What I've heard from within Canonical is that the free AMD driver performs better than the proprietary one. So unless you have requirements other than performance, sticking to the default driver is best.
> Is there a list of drivers that are automatically installed on a fresh Ubuntu install? Yes, but it's too long to be useful. The currently installed list is: find /lib/modules and you can reinstall them with: sudo apt install --reinstall linux-modules-5.15.0-60-generic linux- modules-extra-5.15.0-60-generic so that might resolve the issue after rebooting. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2006955 Title: [amdgpu] Screens not detected anymore in 5.15.0-60-generic (but 5.15.0-58-generic works) Status in linux package in Ubuntu: Incomplete Bug description: I have 3 monitors, but since very recently (yesterday or so), only 1 of them seems to be detected. In the Settings app, under "Screen Display", I used to have a place where I can move my monitors relatively to each other, and adjust each of their settings. Now, I no longer have the monitor drag-and-drop zone, I only have one detected "Unknown display", fixed at 1920x1080 77.00 Hz (physically, it's a 1920x1080 144Hz) and I cannot change any setting except orientation, scaling, and fractional scaling. The bug started happening just when the kernel was auto-updated to 5.15.0-60-generic from 5.15.0-58-generic. `uname -a` reports: `Linux user-desktop 5.15.0-60-generic #66-Ubuntu SMP Fri Jan 20 14:29:49 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux`. When I reboot with 5.15.0-58-generic, all of my 3 displays are detected and working fine. I also noticed the same problem happened when I installed 5.15.0-58-lowlatency.
