<div style="color:black;font: 12pt Verdana, Arial, Helvetica, sans-serif;">When I chose to upgrade from Ubuntu 20.04 LTS to Ubuntu 22.04 LTS (Long Term Stable now seems a bit unrealistic), for some reason they removed my nvidia drivers and installed nouveau. My system freezes intermittently for about 5 minutes when graphically active apps like Firefox, Chrome, GNUCash are running. I am limping along with Chrome set to not use hardware acceleration, a setting both sad and amazingly odd! I recall having a similar problem in 20.04 until I switched to nvidia proprietary drivers. I might do that again, but the controls to do that successfully seem to be harder to find, and maybe 22.04 thinks that they are incompatible. I destroyed my bootability trying to install using the nvidia 340 run file when it failed to make a kernel, and had to reload the whole OS. My GPU is an nVidia GT218 [GeForce 210], NVA8, rather old, now nominally supported by the nvidia 340 series libraries. My system is an Hewlett-Packard p6803w, AMD® Athlon(tm) ii x2 220 processor × 2, with SSD and 16 GB RAM. Ubuntu 22.04.1, Gnome 42.2, Wayland, with all current updates.<br>

How can I help you find the bug? Being both a 20 year hardware and 25 year software computer veteran, I can follow requests pretty well.<br>
<br>
BTW, nouveau does not allow BOINC apps to run on the GPU, which nvidia supported under 20.04.<br>
<br>
I'd hate to have to remove my GPU (the motherboard has a primitive one), or replace the GPU if any compatible ones are still available, or replace my computer to get a stable system.<br>
