[Bug 1455002] [NEW] Thinkpad x200t backlight settings
Public bug reported:
ubuntu 15.04 AMD64
Howto reproduce this bug that did not exist up to ubuntu 14.10
Set your required backlight power with the Fn-Keys and shutdown the
machine. Now bootup again, the login screen and your desktop is on
lowest backlight power that can be set, maybe you have to lower the
light to see your display. You have to power the backlight up with the
Fn-Keys after login., but this will not survive next shutdown.
