Description Elmar Stellnberger 2019-11-01 10:40:28 UTC
My Radeon R5 230 has always worked with modesetting in Full HD out of the box. It is strange why this is no more supported. Even worse if I have to activate the VESA driver this one only yields 640x480. However the VESA standard would also support Full HD, something I remember that has already been implemented with Xorg. I have noted that the driver name has changed from radeon to amdgpu. The radeon kernel module is loaded. xorg-x11-driver-radeon is installed and I wonder why I can not state "radeon" in the Driver section of my xorg.conf

This is what xrandr offers with the vesa driver:
Screen 0: minimum 640 x 480, current 640 x 480, maximum 640 x 480
default connected 640x480+0+0 0mm x 0mm
   640x480        0.00*

> [  2141.996] (II) AMDGPU(0): [KMS] drm report modesetting isn't supported.

means the amdgpu kernel driver didn't initialize. Please attach the output of dmesg.

You need to install the firmware package:
[    1.629363] [drm:radeon_pci_probe [radeon]] *ERROR* radeon kernel modesetting for R600 or later requires firmware installed

  Ahh, I should have known. That is a detriment with the Debian live dvd. Basically I could install the firmware with hindsight and then restart the X-server. 
  There is another bug with the VESA driver which has gone unreported yet. If the DPMS standbys the screen then the color palette is wrong on resume (no s2ram, only a display standby). I wonder if anyone cares to still support the VESA driver.
