Black screen with ubuntu 64 22.04.1 LTS


I’m running a K2200 quadro with ubuntu.
After installing the 525 driver and logout, display is black all the time.
I’ve seen the topic several times and tried many solutions but none of them did the trick.
This PC works correctly with windows.
Here’s the bug report generated with an ssh connection.

Thanks for your help.

Please check if the 470 driver works, switching in Software&Updates

Thankd for your answer, same result with 470. Here’s the new log:
