Public bug reported:
I have a Lenovo Legion 7 Laptop with AMD 7000 series APU and dedicated
NVIDIA RTX 4060 GPU.
Issue description:
Originally, I started with ubuntu 22 which had several missing Drivers. One of
the Problems was that the sceen would sometimes freak out with partial white
flashing which quickly worsens until the whole screen turns white. The OS keeps
running. I can still hear audio and the mouse is still being rendered ontop of
the white screen, changing when I hover over elements. I have also had success
when logging out on the top right corner through trial and error (since I
cannot see whats behing the white screen). Restarting the Machine or logging
out resolves the issue Temporarily.
I have tried several things with varying success:
- I have tried installing KDE plasma, which did not fix the issue
- I have tried switching GPU Drivers (530 or 535 is the offered one in ubuntu,
also tried the generic driver with the same issue) Allegedly this problem is
known with these nvidia driver versions so I tried to install version 550
manually, but that led into a boot loop.
- I have installed ubuntu 24.04 and upgraded the kernel to 6.9-RC6, which
greatly improved on the issue compared to ubuntu 22.04. However is is still
almost 100% reproducible when starting full screen applications such as a game
or going into full screen on youtube
- I have lowered the screen refresh rate from 244hz to 60hz, which also reduced
the frequency of the issue appearing. I can now watch youtube on full screen
most of the time but playing a game for instance still does not work
As for the requested kernel information, I cannot find how to attach a
"separate attachment" here.
Best regards,
Julian Bechtold
