[SOLVED] Terrible graphical performance

My system has an AMD Radeon R7 240 graphics card, amdgpu module and modules that use it are loaded, VDPAU packages are installed but "vdpauinfo" returns

display: :0.0   screen: 0
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
Error creating VDPAU device: 1

and "grep -i vdpau /var/log/Xorg.0.log" returns nothing

To fix this, should I add "export VDPAU_DRIVER=radeonsi" to the ".bashrc" file?

Re: [SOLVED] Terrible graphical performance

If you have no nVidia card, try blacklisting nVidia modules at boot.

to try it out, add this to the grub boot line... tap 'e' to edit the grub boot line at boot.

module_blacklist=nvidia

If it works, add a file to your /etc/modules.d/

/etc/modules.d/nvidia-blacklist.conf

# generated by nvidia-installer
blacklist nvidia
options nvidia modeset=0

I hope this helps

Re: [SOLVED] Terrible graphical performance

That didn't help, but during boot, I caught a glimpse of "ERROR" and "radeon" and this is what my # "nano /var/log/kern.log" said

[drm] radeon kernel modesetting enabled.
[drm:radeon_pci_probe [radeon]] *ERROR* radeon kernel modesetting for R600 or later requires firmware installed
See https://wiki.debian.org/Firmware for information about missing firmware
[drm] linux how to see bootamdgpu kernel modesetting enabled.

The Wiki doesn't say why the firmware is missing but the "Firmware missing from Debian" section did point me to the right place.
Now which "/tree/amdgpu/oland_*.bin" should I install?

Well, under the assumption that you have Daedalus installed, you will need to add "non-free-firmware" to your sources.list, do an apt update, and install firmware-amd-graphics, then reboot.

Re: [SOLVED] Terrible graphical performance

All of the lines already have "non-free-firmware" appended after "main". # apt install firmware-amd-graphics did work. Thanks!
