Kubuntu 22.04 vs Kubuntu 20.04 with stability on nvidia (lemmy.sdf.org)

Hi

I have a laptop with Ryzen 5900 HX and nvidia RTX 3070 GPU with kubuntu 22.04 (kernel 5.15) installed. The thing is I tried to switch the driver from 520 (it freezes quite often on when entering the desktop and sometimes freeze when doing normal activities like browsing) to 440 (lesser freeze But it still happened randomly). the current solution: hard-reset the computer, which is a notoriously bad solution. So, I have an idea by wipeout everything and downgrade to Kubuntu 20.04 which is older. But, I think it is much more stable. Do you think downgrading is good idea?

@meiko60 why do you think that the reason for the freezes is the graphics driver. Isn't Linux completely freezing typically a running out of RAM (when you haven't set sufficient swap partitions or swap files). On KDE, you can enable the classical Ctrl+alt+del key to reset the xserver/Wayland (advanced keyboard options). Could you check whether this still works when the freeze occurs? Are there any special things in your system log?

I don't think RAM is an issue and besides on the journalctl. I got this nvidia-modeset: ERROR: GPU:0:

What do you think?

@meiko60 newest Nvidia drivers are at the moment 535.xx. you could maybe try upgrading to se whether the situation changes. It's easiest to get new Nvidia driver when following the instructions for installing CUDA. You typically don't need to install all of the CUDA SDK and could for instance just install the package cuda-drivers

I am a casual gamer and I heard this 535 have issue. I might try upgrade to latest 6.2 kernels and upgrade to 525 https://www.gamingonlinux.com/2023/08/recent-nvidia-drivers-are-causing-issues-for-proton/
