Bug Description

Binary package hint: xorg

xserver-xorg-video-vesa doesn't work when KMS is in use on my machines, but changing /etc/X11/xorg.conf.failsafe to use fbdev lets failsafe X work. pm-utils has a method of determining of KMS is in use that could possibly be used in the /etc/gdm/failsafeXServer script to determine which driver should be picked for fallback_driver in there instead of just using vesa.

grep -q -E '(nouveau|drm)fb' /proc/fb

a nouveau KMS fb is called nouveaufb, a radeon KMS fb is called radeondrmfb a vmware KMS fb is called svgadrmfb and an intel KMS fb is called inteldrmfb. those are the only use cases of KMS currently.

---------------
xorg (1:7.5+1ubuntu7) lucid; urgency=low

  * debian/local/Failsafe/failsafeXServer:
    + Actually produce xorg.conf.failsafe with the detected driver.
      Important for failures while running in KMS mode.
      (LP: #496773)
    + Force overwrite of existing xorg.conf.failsafe. Since above
      change produces different xorg.conf.failsafe's depending on
      what driver was selected, we must force it to regen each time.
