Before introducing the recent changes in the YaST land, the team would like to congratulate the openSUSE community for the release of Leap 15.2. It looks like a pretty solid release, and we are proud of being part of this project.

Having said that, let’s focus on what the team has achieved during the past sprint.

Summary of the (Auto)YaST Changes

• Fix an embarrassing installer crash (boo#1172898). We suspect that it might be a Ruby problem, but we implemented a solution in the installer.
• Add a mechanism to ask AutoYaST to export a reduced profile. At this point in time, only the yast2-users module supports such a mechanism.
• Publish our conclusions about the usage of wizards in the Expert Partitioner.
• Study the impact of adding support for new types of LVM logical volumes in our storage layer. We will use the outcome of such research to plan future work in this area. If you are curious, you can start by having a look at LVM features and YaST document.
• Use the REMOVE libstorage-ng view when deleting devices. You can check libstorage-ng#740 if you are interested in the mentioned view.
• Remove the obsolete repository initialization, which made installation using an unsigned/self-signed repository impossible.
• Do not solve dependencies while checking the connection to libzypp.
• Add support to collect memory usage data during installation. If you are interested, check the follow-up document, which contains some nice ideas for the near future.
• Backport to SLE 12 SP4 some fixes related to Ruby gems loading in order to solve a problem some appliances were having after a Ruby security update.
• Do not remove /etc/hosts entries during autoinstallation.

The YaST Blog Poll Is Still Running

A few weeks ago, we announced that we were changing our sprint reports’ format to reduce the amount of work that it takes us to write them. Thus, instead of using a consistent and self-contained nice story, we decided to go for a digest-like approach.

After having published two reports using the new approach, we decided to open a poll to know your opinion of such a change. We have already received quite some feedback, but the poll is still open and we would love to hear from you.

The release of openSUSE Leap 15.2 continues to expand its use and is now available for Windows Subsystem for Linux in the Microsoft Store.

Leap can be executed on top of WSL to deliver the power of openSUSE to the Windows world.

WSL is a compatibility layer for running Linux binary executables natively on Windows systems. WSL is available for 64-bit versions of Windows 10 and Windows Server 2019.

System Administrators who like using tools such as rsync, tar, grep, sed, awk, and more might be limited to corporate environments where the use of Windows is mandatory. With openSUSE Leap 15.2 for WSL, sysadmins are empowered with the freedom, ability and tools to manage systems and networks.

WSL allows users to run Bash shell scripts and GNU/Linux command-line tools like vim and emacs; languages like NodeJS, Javascript, Python, Ruby, Rust, Go and more; and services like MySQL, Apache, MongoDB and PostgreSQL. Additional software is available using openSUSE’s package manager zypper.

Leap 15.2 on WSL isn’t just for sysadmins; developers that want to leverage Linux and users who would like to learn it without setting up a dual-boot system or virtual machine have an opportunity to try openSUSE and a few other distributions on WSL.

Before installing any Linux distributions on Windows, users must enable the “Windows Subsystem for Linux” optional feature. Documentation about using WSL is available on the openSUSE wiki and on Microsoft’s quickstart guide.

I have been working at what has been my dream job at Whirlpool Corporation for six years. Every day I was either working on something new or making something better. The way I saw it, every day I was given a great gift of being payed to play with toys. Sure, they were appliances or … Continue reading New Adventures | Unexpected Change in Employment Status →

Estu Fardani is a helpful & jovial fellow whom I met at the openSUSE Asia Summit last year in Bali, Indonesia. Recently, for the openSUSE Virtual Summit, Estu did a short presentation on Podman. His presentation video is available on YouTube and slides deck available on Google Slides.

While I am not a fan of alias docker=podman I believe Estu added that part in his slide below to make the Podman transition a bit smoother for users already familiar with Docker commands.

Note that the latest release of openSUSE Leap, i.e version 15.2, comes with support for Podman through the libcontainers-common package.

Previously, if one needed to experiment with Podman and/or deploy in production then openSUSE Tumbleweed, Kubic or MicroOS were the supported choices. Now, one may deploy Podman containers on their existing Leap infrastructure (after upgrading to the latest version 15.2).

All sessions videos from the openSUSE Virtual Summit 2020 are available on the openSUSE YouTube channel.

Almost finished this on time… 16th Noodling of things There are certain numbers, due to my nerdiness, that have importance to me. 16 is one of them.

२ जुलाई २०२० को openSUSE Leap 15.2 संस्करण उपलब्ध हुआ।

openSUSE Leap एक निशुल्क और लिनक्स-आधारित ऑपरेटिंग सिस्टम है जो आप अपने पीसी, लैपटॉप या सर्वर पर इस्तेमाल कर सकते है। Leap 15.2 और SUSE Linux Enterprise एक समान कोडबेस उपयोग करते है जिस से openSUSE Leap 15.2 की स्थिरता और ज्यादा मज़बूत होती है।

यह विशेष संस्करण कृत्रिम बुद्धिमत्ता, यानी आर्टिफिशियल इंटेलिजेंस, को अधिक आसानी से सुलभ बनाता है। निम्नलिखित पैकेज ऑफिशल रिपॉजिटरीज से प्राप्त किए जा सकते हैं।

• टेनसरफ्लो
• पाइटोर्च
• ग्राफाना
• प्रोमेथेउस

इस संस्करण में अधिक कंटेनर टूलस् शामिल है, जैसे कि कुबनेटिस् (जो पहली बार के लिए Leap संस्करण में उपलब्ध हुआ है) हेल्म और सिल्यम।

Even if the 99,9% of times all the applications released through the official repositories are reliable and perfectly working, sometime a buggy package might get installed on our systems after an update. With a few steps we can rollback to the previous version taking advantage of the feature made available by package managers and repositories.

I’m going to begin this rant by saying that there are some things that that the Stack Exchange network is really good with: mainly, programming help.

However, it really sucks when it comes to providing help with a specific application where there is already a community. For the past year, I have been the #1 person to answer questions on tor.stackexchange.com. I’m not saying that to pat myself on the back; just to say that I have actually been doing this for a little while. However, I feel that many, if not most, of the questions should never have been there. Here’s what I mean:

1. Nobody googles anything for themselves anymore. A huge number of questions have been answered time and time again and can be found by just searching.
2. Nobody reads documentation or man pages.
3. There are better places to ask the questions.

While #1 and #2 are annoying, it’s #3 that I want to focus on. For example, we get a lot of questions about running Tor relays. Many times, I will copy and paste from the documentation and answer their question. However that question should never have been there at all. It should have been posted to the tor-relays mailing list. That way more people who actually run relays can answer and give better insight. Also other newbies to the list can learn also and the person asking the question can actually be a part of the community.

When it comes to subreddits that are based on a specific application like Tor, take my 3 examples and multiple it by 1000x because it is a continual cycle of the same crap week after week. I had to leave before I flamed someone for asking the same stupid question for the 9th time in a row. I miss good netiquette.

Dear Tumbleweed users and hackers,

Week 27 has mostly been in the light of the release of openSUSE Leap 15.2. With the developers mostly focusing on getting the best Leap release yet out of the door, it’s just natural that Tumbleweed has seen a bit less of churn. But honestly: has it? We have released 6 snapshots during this week so that does not talk for the ‘less active development’ of Tumbleweed during this period. The snapshots released were 0625, 0626, 0627, 0628, 0630, and 0701.

The most relevant changes in these snapshots were:

• Linux kernel 5.7.5
• KDE Plasma 5.19.2
• systemd 245.6
• Mesa 20.1.2
• Valgrind 3.16.0
• hplip 3.20.6

So, not much of a slow-down to be seen. And the staging projects are also still busy with various things, like:

• Python3 packaging rework: switch away from multiple spec files to OBS multi build flavors.
• openSSL 3.0
• RPM change: %{_libexecdir} is being changed to /usr/libexec. This exposes quite a lot of packages that abuse %{_libexecdir} and fail to build

I have recently bought a 14″ laptop, the HP Pavilion 14-ce0830nd. This is a mid-range laptop. It is an upgrade from my previous laptop, the ASUS VivoBook X402NA-FA112T. However, this machine is not without it flaws.

Design and hardware

The HP Pavilion 14-ce0830nd looks and feels like a quality laptop. The body around the keyboard is made of anodized metal and feels quite premium. Somewhat less premium is the plastic cover at the bottom and the plastic screen cover. A nice design touch are the hexagonal shapes in the laptop speaker grille that stretches all the way from left to right. It houses the B&O PLAY speakers. There is a very large trackpad at the bottom of the laptop. The touchpad has invisible integrated buttons (by clicking the whole touchpad on the left bottom or right bottom).

On the left side, this laptop features 2 USB 3.2 type A ports. It also features a headphone jack, an opening for a kensington lock and a SD card reader. On the right side, this laptop features a port for the power plug, an ethernet adapter, a HDMI port, a USB 3.2 type C port and a fingerprint sensor.

The display has an interesting hinge mechanism, that raises the laptop a couple of millimeters when you open it. This means that the keyboard has a slight slope. Which is more comfortable for typing. The disadvantage of this mechanism is that it blocks the hot-air vents on the backside.

The display itself is bright enough, but not extremely bright. The colors look good enough for me, but they are not stunning by any means. The viewing angles of the display are good.

The keyboard feels very good for typing. I could see myself writing entire essays on this laptop. I find it annoying that by default the multimedia keys are enabled instead of the function keys. When I try to access Krunner, I decrease the brightness of the screen instead. This is easily changed in the BIOS. HP calls them ‘action keys’ and you can disable them. I am less enthusiastic about the track-pad, which is by default way to sensitive for my taste. I made some adjustments in the KDE System Settings and now it works fine. It does have a good size. A disadvantage of that size is that the distance between the left bottom click and the right bottom click is too far apart.

The B&O PLAY speakers sound good, relative to other laptop speakers. Voices in songs are very clear. Pop music and Jazz music sound great. The speakers are not very loud. Like many other laptop speakers they fail to produce very crisp high tones (e.g. violins in classical music) and the bass doesn’t feel ‘heavy’ enough (in R&B music). But that is to be expected from laptop speakers.

The weight is just 1,59 kilogram, so its a light laptop. Which is good for portability. The laptop feels quite sturdy because of the metal housing. However, it has a plastic bottom plate which could break, if you access the internals too many times.

Installing openSUSE Leap 15.2 Beta

I installed openSUSE Leap 15.2 Beta in March 2020, 3 months before the official release. The install went without issues. I have settled on the following disk layout:

• SSD 256 GB
  • 500 MB – EFI (boot partition)
  • 80 GB – BtrFS (root partition)
  • 9 GB – Swap (swap partition)
  • 16 GB – NTFS (Windows backup partition)
  • 149 GB – NTFS (Windows partition)
• HDD 1 TB
  • 1 TB – XFS (home partition)

I did encounter issues with hardware detection and drivers of the WiFi chipset and the videocard. I did succeed to resolve the WiFi issue. Unfortunately, I was not able to resolve the videocard issue.

WiFi issue

I knew from past experience that you can still encounter WiFi issues with cards that don’t have proper Linux support. The Realtek RTL8821CE is such a card. After installation, I discovered that I had no access to WiFi. Which makes the laptop a very expensive brick. Fortunately, this laptop has an Ethernet adapter, so I could plug it in on my local wired network.

I first tried installing a driver for the RTL8821CE, which was packaged for openSUSE. However, this failed to work. The second thing I tried, was to follow this guide on manually installing the driver from Github. But that also didn’t work. After multiple hours trying to problem-solve this issue, I was ready to spend my money on an easier solution. In the end, I bought 3 WiFi cards:

• Intel 3168NGW (PCI-Express)
• TP-Link Archer T3U (USB type A)
• TP-Link TL-WN823N (USB type A)

Replacing the internal Realtek card was fairly straightforward. After unscrewing a couple of screws, the bottom plate of the laptop can be removed. And the internal of the laptop are easy to reach. After replacing the Realtek card, the new Intel card produced a working WiFi signal. Which is great! However, the signal strength is low. And my WiFi reception is not great when I am indoors. So I wanted a better solution.

I initially purchased the TP-Link Archer T3U with the WiFi protocol ‘802.11 ac’. Which was a mistake. It uses the Realtek RTL8111/8168/8411 card internally. Which (surprise surprise) is not supported on Linux. I tried to install the driver the easy way (packaged for openSUSE) and the hard way. Both ways didn’t succeed. Which meant that I had to purchase another USB WiFi dongle.

This time, I looked for a WiFi card that had Linux support out of the box. I purchased the TP-Link TL-WN823N card with the WiFi protocol ‘802.11 n’. And it works without any problems on openSUSE. So my suggestion for other Linux users with WiFi problems: purchase this (13 euro) USB WiFi dongle and save yourself hours of fiddling around with DKMS drivers that may or may not be working.

Nvidia videocard issue

The HP Pavilion 14 laptop is an optimus laptop, which means it features both integrated (Intel) graphics and dedicated (Nvidia) graphics cards. openSUSE Leap 15.2 doesn’t install the xf86-video-intel package by default. This is easily remedied by searching and installing this package via YaST and rebooting.

The Nvidia videocard wasn’t showing at all. When the proprietary Nvidia gfx-G04 / gfx-G05 drivers became available, I wanted to try to resolve this issue. I installed SUSE-prime to be able to switch between Intel and Nvidia graphics. SUSE-prime has a very easy to understand Wiki page. After installing the proprietary G05 drivers and SUSE-prime, the Nvidia card was still not showing. I tried the G04 drivers instead and replaced SUSE-prime with SUSE-prime-bbswitch. But I still wasn’t able to switch between the Nvidia and Intel GPUs. The G04 driver did appear to work better than the G05 drivers, because I was able to open the NVIDIA X Server application. Which presented me with an error dialog, informing me to run nvidia-xconfig as root.

When I followed the recommendation, an empty xorg.conf file was created. Which caused Xorg not to work at all after reboot. I had to remove this xorg.conf file to get my KDE desktop back up and running.

sudo rm /etc/X11/xorg.conf

In the blog of another openSUSE user (Cubiclenate) I found that I was not alone in trying to resolve this issue. He linked me to the openSUSE Bumblebee Wiki page. These instructions looked very daunting, so I decided that it wasn’t worth the effort. I can play the same games on Windows (via Steam) where the Nvidia drivers are working.

Dual booting Windows

My reason for installing Windows 10 has nothing to do with the mentioned Nvidia issues. The reason to install Windows is to be able to transfer files between my computer and my Samsung Galaxy S phone and my Fitbit Versa watch.

I encountered problems in the past, trying to transfer pictures and music via Dolphin or via KDE Connect. I did manage to transfer a couple of files without a problem. But a mass download of all pictures from my Samsung phone to my computer was to much for Dolphin/KDE Connect to handle. And uploading a large collection of music from my computer to my Samsung phone was just as much of a problem.

This laptop originally shipped with Windows. I formatted both hard drives when installing openSUSE. I left some space on the SSD for a fresh Windows install. Windows 10 installed without any problems. When I restarted the computer, GRUB only showed the openSUSE entries, so I couldn’t boot into Windows 10. This issue was easy to resolve, I found the solution online.

In Dolphin I opened the Windows partition. Then I opened a terminal and entered:

sudo os-prober
grub2-mkconfig -o /boot/grub2/grub.cfg

GRUB directly found my Windows partition and added it as an option in the GRUB menu. After his, I was able to boot into Windows 10.

As many people have experienced before, Windows 10 is very hostile to your privacy. I already gained an advantage by doing a clean install. This way I didn’t have to deal with the unwanted crapware that HP installed by default on my system. Next, I disabled all spying options in the settings. Windows 10 was also automatically installing games like Bubble Witch 3 Saga and Candy Crush Friends. This apparently cannot be disabled. Microsoft, please stick to Mahjong, Minesweeper, Solitaire and Sudoku.

So what did I install? Mostly open source applications: Firefox, LibreOffice, GIMP, VLC media player, Elisa music player, ImageGlass, Notepad ++, openRA and SuperTuxKart. I also installed Steam (not open source) to play some games. And I installed the Fitbit app (also proprietary software) to communicate with my watch.

Gaming

I have installed OpenArena, Xonotic, SuperTuxKart and OpenRA on both openSUSE and Windows. I will use these open source games to compare gaming performance between openSUSE and Windows. The GeForce Experience app (which controls the Nvidia GPU) didn’t recognize these as games and thus everything runs on the Intel GPU. So this is a fair comparison.

Average FPS	openSUSE Leap 15.2	Windows 10
OpenArena (max settings)	45 FPS	90 FPS
Xonotic (ultra settings)	55 FPS	100 FPS
SuperTuxKart (max settings)	9 FPS	17 FPS
OpenRA – Red Alert (default settings)	60 FPS	60 FPS

I wasn’t expecting this difference in gaming performance. The average frame-rates are almost twice as good on the Windows side. Apparently the Intel GPU drivers on the Windows side are better optimized.

The GeForce Experience app did recognize the games that I installed via Steam on Windows: Tomb Raider, DiRT Rally and GRID autosport. These 3 proprietary games are used to see how well the Nvidia GPU is handling them.

Average FPS	Ultra settings	Low settings
Tomb Raider	40 FPS	60 FPS
DiRT Rally	30 FPS	54 FPS
GRID autosport	16 FPS	60 FPS

Not surprisingly, the frame rates on Ultra settings are not great. However, these games are very playable on full HD resolution on medium/low settings.

Multitasking

The HP Pavilion 14-ce0830nd handles multitasking like a boss. It has no problem handling multiple tasks at the same time. For fun, I tried opening Firefox, Dolphin, Gwenview, Darktable and LibreOffice Writer, while playing music in Elisa music player at the same time. The image below shows the result. The applications started almost instantly. None of the CPU cores reached 100% and most of them stayed below 50%. The 8GB of memory was plenty to handle all of these tasks.

Conclusion

Would I recommend the HP Pavilion 14-ce0830nd? To be honest, its a mixed bag on openSUSE. Installation of openSUSE Leap 15.2 was very easy. And installation of a dual boot system with Windows 10 was easy as well. The laptop has an attractive look and feel. The display, speakers, keyboard and external ports are all good. The touchpad is too sensitive, but this can be adjusted in the KDE settings. The machine has enough RAM, enough storage and the hard drives are performant. The Intel CPU/GPU is great. Which means that this is a great machine for multitasking. The gaming performance on the Intel GPU on openSUSE Leap 15.2 is good enough to play various open source games on medium/high settings.

There are 2 big issues why I wouldn’t recommend this machine:

• the Realtek WiFi card is not supported under Linux
• the Nvidia GPU is not working in openSUSE Leap 15.2

I feel that if you are looking for a good Linux laptop, it should come with an Intel WiFi/Bluetooth chip. And that it is better to avoid laptops with Nvidia optimus videocards.

So is this laptop a disappointment? Not at all. After a bit of tinkering, I am quite happy with it. I replaced the internal WiFi card and use a 13 euro USB WiFi dongle if I need an even better signal. I don’t mind that the Nvidia GPU is not working on the openSUSE side. This machine offers a big performance upgrade in comparison to my previous laptop. I enjoy the better display, speakers and the great keyboard. I have a Logitech wireless mouse plugged in, so I don’t have to use the track-pad exclusively. The battery is also better than my previous laptop. For me, these are enough reasons to happily keep running openSUSE Leap on this laptop.
