Anki black screen Linux Mint

Anki Help
1

I’m using linux mint with KDE Plasma and I’m not able to use anki, sometimes it works the first time I open it but when I close it and try to open it again it gets this black screen. I have tried to change the display driver but it didn’t work. Does anyone know how to solve it?

  1. Did you go through all of these steps? Troubleshooting - Anki Manual
  2. Please post the version info that you can access via #3 from the link above.
  3. Does any of these solve it? Blank Main Window - Anki Manual
  4. What gets printed in the terminal if you run anki from the terminal? Please send the entire output.

Hi, good morning! Yes, I went through all these steps and none solved. The version is this:

Anki 25.09 (539054c3) Python 3.13.5 Qt 6.9.1 PyQt 6.9.1 Platform: Linux-6.8.0-79-generic-x86_64-with-glibc2.39

None of these solved the problem. I tried all of this link Blank Main Window This is what appears when I run the anki through the terminal:

Sorry I didn’t know I couldn’t make two posts, I thought that because it was on reddit other people would see it.

I switched to Cinnamon today and Anki worked normally. But in KDE plasma it doesn’t work.

Should I delete reddit post?

Cross-posting is fine if you feel the need – as long as you let folks know that you’re doing it. Then helpers can see if you’re already getting help, and others with the same question know where to find the answer.

Got it, thanks for helping. I’m migrating from Windows 10/11 to Linux Mint, it’s been difficult. In linux I find some problems that I can’t solve on my own.
