The GPU chip on my motherboard died, and so I plugged in a cheap video card, a maxsun AMD Radeon R5 220 2GB Graphics Card. As the result my resolution is locked at 1024 x 768, which makes work very difficult.
$ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 76.00* The graphics card supports my desired resolution of 1920x1080, but it is not accessible. The module is loaded: $ lsmod ... video 65536 2 amdgpu,radeon I tried several things: I put the statement xrandr --output HDMI-1 --mode 1920x1080 in my .Xresources file. I have modified the line in /etc/default/grub to be GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.alpha_support=1" I uncommented this line /etc/default/grub and changed it so GRUB_FXMODE=1920x1080 I have several questions Is there something in BIOS I need to change with the switch to a graphics card. I didn't see it. Was my choice of card unwise? Is buying a new and better card a good idea? What inexpensive Intel or Radeon card can someone recommend that is known to work? -- Haines Brown
