[Bug 1462611] Re: monitor off after grub


i feel a bit stupid as i now found out where this comes from and i didnt
try that before. my linux boot command line included "$vt_handoff".
removing it made everything work as expected. so it is definitly not a
kernel problem i think.

  monitor off after grub

Status in linux package in Ubuntu:

Bug description:
  on my main machine the monitor shuts off after grub, but the system
  boots in background. the monitor wont come back on so i have to power
  it completely off and on again. if i do this early enough i can see
  the glowing kubuntu logo. i tried various "video=" kernel options
  among other things but with no success. my laptop has an simliar
  problem except the screen goes back on when displaying "starting 219".

  i have a radeon r9 270x and the monitor is connected via dvi-d.
  my laptop has a r710 radeon.
