[...] Hi, thanks for providing the info requested, that's really helpful. I'm not the best person to answer your questions because I have never needed to take much interest in graphics card technology, so I expect that I'm quite ignorant of it relative to many readers of this list. So my contribution here is limited to trying to help you provide information that might allow someone else to give you informed answers. We have at least definitely indentified the card that you have. These lines from the 'inxi' output you provided: > Device-1: AMD Cedar [Radeon HD 5000/6000/7350/8350 Series] > vendor: Hightech Information System > arch: TeraScale-2 plus that you wrote previously that you have a: > AMD Radeon R5 220 2GB Graphics Card confirm that you have a: Radeon R5 220 card released 21 December 2013 [1] which uses: Terascale 2 40nm GPU which dates from September 2009 [2] which is why your card was a "low end" (ie budget) model when it was released, because it was AMD's way of selling off stock of a GPU which was "old" at the time the card was released. > Are you saying that the needed driver is provided by the > xserver-xorg-video-amdgpu package and do I do not need to install it. > Indeed, it was istalled automatically in my system. All I can do is point you to the Debian wiki [3] that I mentioned previously, which says that you don't need xserver-xorg-video-amdgpu, and you do need xserver-xorg-video-ati, which you have shown that you have installed. In the information that you showed, I would be very concerned about this: > [ 52.592548] [drm:radeon_pci_probe [radeon]] *ERROR* radeon kernel > modesettin> That error message has been truncated. What does the full message say? Because I wonder if it says something like: "radeon kernel modesetting ... requires firmware-amd-graphics" So can you please show the output of: $ apt list --installed 'firmware-amd-*' And if firmware-amd-graphics package is not installed, can you try installing it and see if that fixes your issue. If it does not, then I am out of ideas and hopefully someone else will be able to further assist you. The firmware-amd-graphics package is provided by Debian in the non-free-firmware repository. Also, in your 'inxi' output, these lines are bad: > loaded: vesa > unloaded: fbdev,modesetting,radeon because you need the radeon driver to be loaded !! > Does the statement resolution: > 2024x768 mean it is current or is the only available one? You have 1024x768 as the current resolution because that is the maximum provided by the vesa driver, which is currently the only working driver, and in use. To get the higher resolution that your card is capable of, you need to get the radeon driver working.
