When I start anki in my Ubuntu machine, this popups

black screen popup

So I tried starting Anki using terminal, and this is the error it shows.

libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

Specs

  • OS version - Ubuntu 20.04.2 LTS
  • Graphics - AMD Radeon RX 580 Series
  • Processor - AMD Ryzen 7 3800x 8-core processor × 16

I have tried reinstalling my graphic drivers but it didn't work.

Also I was trying to do this method, but I couldn't as I have very low experience with linux and my graphic card is AMD

I have also tried this, but it doesn't seems to work.

If you are using Anki (2.1.54 in my case) with Qt6, try enabling software rendering:

echo software > ~/.local/share/Anki2/gldriver6

Whenever I encounter error messages about missing drivers / files / shared libraries, I will try to find out which deb package the file can be found in:

apt-file search swrast_dri.so
--> libgl1-mesa-dri: /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so

Then I will install that package

sudo apt install libgl1-mesa-dri

and try again.

If apt-file isn't installed, you can install it by typing

sudo apt install apt-file
apt-file update

That being said, anki is one of the very few packages I'm downloading directly from their website apps.ankiweb.net because it's a very active project. Installation instructions are provided on the same page. If you do this, make sure to remove the packaged version from your system beforehand: sudo apt remove anki

  • I ran apt-file search swrast_dri.so and this was the output libgl1-mesa-dri: /usr/lib/x86_64-linux-gnu/dri/kms_swrast_dri.so libgl1-mesa-dri: /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so , then I apt installed libgl1-mesa-dri. Still it doesn't seems to work – Aathik May 22 '21 at 15:12
  • That's unfortunate. In that case you can still try to install the version from anki's website. They package with all/most required libraries -- that has worked well for me in the past. Another idea: do you have any plugins that could cause the issue? – jcsjcs May 22 '21 at 15:23
  • I am installing anki from the official website for the first time. – Aathik May 22 '21 at 15:26
  • You mean the problem is happening with anki installed from the official website? In that case, try installing the ubuntu package and see if that works. – jcsjcs May 22 '21 at 15:29
  • Due to some reason the profiles window works, but the main anki window doesn't work – Aathik May 22 '21 at 16:01
  • Nope, the ubuntu version also doesn't work – Aathik May 22 '21 at 16:01
  • What does this https://stackoverflow.com/a/32056721/13853882 say, I couldn't understand – Aathik May 22 '21 at 16:03
