There is two kernels available on this system: - 5.4.0-47-generic - 5.4.0-48-generic With kernel 5.4.0-47-generic: - GNOME shell loads properly on Radeon X1950 PRO, - Unvanquished game runs on ATI Radeon X1950 PRO at 70 fps on 1280×720 resolution, - Unvanquished game runs on ATI Radeon 9500 at 40 fps on 640×480 resolution. Everything looks consistent with the limits and the age of the hardware. With kernel 5.4.0-48-generic: - GNOME Shell never finish to load on Radeon X1950 PRO, either a grey screen is displayed and keyboard shortcuts does not respond, or the top bar is stuck between the center and the top of the screen and the shell does not respond, or the top bar on the top of the screen but the shell does not respond, to get a desktop I run `sudo systemctl stop display-manager` then `startx /usr/bin/lxsession` from a TTY. Running GNOME Shell with startx or from a lone xterm started with startx leads to same issues. - Unvanquished game runs on ATI Radeon X1950 PRO at 7 fps on 1280×720 resolution, - Unvanquished game runs on ATI Radeon 9500 at 3 fps on 640×480 resolution. Note: for unknown reasons, GNOME Shell loads properly on the ATI Radeon 9500 but not on the Radeon X1950 PRO. Everything is slow. When the game is running, a very high load is reported by htop, which does not look like the experience seen on the 5.4.0-47-generic kernel. When the game is running cycling between windows using Alt-Tab takes a lot of second while it's immediate on 5.4.0-47-generic kernel. Also, even without the game running or on a lightweight desktop like LXDE, cycling windows is not smooth and window refreshing is slow enough to be noticeable. About the hardware, note that: - the CPU only has one core, no hyperthreading (AMD Athlon 64 FX for socket 939), - the GPUs are AGP ones using R300 and R500 technology (pre-TeraScale), - there is 3GB of DDR RAM, - there is no on-disk swap but zram-based swap in compressed ram is used, - system is stored on and boots from an USB 3.1 key plugged on an USB 2.0 port, - /tmp is a tmpfs ram disk, - CPU is set to performance profile, - the install is not really messy and not many packages are installed, this USB key is purposed for hardware/system testing and to diagnose such issues.
