Display resolution fails in the sense that

  $ 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*

  $ lsmod 
  ...

radeon driver is good for my graphics card.

On other installations of Daedalus the resolution is
automatically the desired 1920x1080.

Running this has no effect:

# xrandr --output HDMI-1 --mode 1920x1080
xrandr: Failed to get size of gamma for output default
warning: output HDMI-1 not found; ignoring

In /etc/default/grub, I added the resolution to the line
RUB_CMDLINE_LINUX_DEFAULT="quiet" to no effect.

Installation of the operating system did not install xterm by
default.
