Comment 7 for bug 2062426

On my Ubuntu 24.04, I seem to be getting the same issue when running 6.8.0 kernels (but not on 6.5.0 kernels).
I'm currently using Nvidia driver version 535.171.04 with mobile RTX 3080.

The issue happens always when going to suspend (by closing the lid).
When waking up, X or GDM3 seems to have crash and forces me to log in again. The system seems to be a bit slow/unstable still for a some tens of seconds after logging in.
