Can you post the output of: $ cat /sys/devices/virtual/backlight/fujitsu-laptop/brightness $ cat /sys/devices/virtual/backlight/fujitsu-laptop/max_brightness ?
$ cat /sys/devices/virtual/backlight/fujitsu-laptop/brightness 0 $ cat /sys/devices/virtual/backlight/fujitsu-laptop/max_brightness -1 The crash happened immediately after install. The kernel has been upgraded to 4.0.3-300.fc22.x86_64 now so I don't know the output of these commands before.
We'll fix the crash but backlight adjustment won't work for this laptop. Is there any other devices listed under /sys/devices/virtual/backlight/ ? Did backlight adjustment work before?

See above ;) And I rebooted the 4.0.0-0.rc5.git4.1.fc22.x86_64 kernel, same outputs.
(In reply to Marco Nolden from comment #15) > It's actually a desktop machine. Ok thanks, but that's a kernel bug since it makes the rest of the system assume that there's a backlight when there actually isn't one. You should report that as a kernel bug. The crash here will get fixed in the next gnome stable release.
