Public bug reported:
Binary package hint: xorg
I have a thinkpad R50e, which has a intel 82852/855GM.
I like my brightness level to be at the maximum value (7).
In /sys/devices/virtual/backlight/thinkpad_screen, I have :
actual_brightness : 7
brightness : 7
When I switch from a graphical console (VT7) to a text console (VT1) using
ctrl-alt-f1, the brightness is kept.
When I switch from a text console (VT1) or a graphical console to a graphical
console (VT8) using ctrl-alt-fX, the brightness is set at its minimal level (0).
actual_brightness : 0
brightness : 0
I have the same result with the user-switch applet.
I didn't have this issue with karmic.
