Ok, I am confused by all your earlier replies then. You seem to say that t-acpi being loaded does not change anything. Did you find any configuration (I mean is t-acpi loaded? + which backlight method does xrandr report?) that always work or always fail?

Did you find any configuration (I mean is t-acpi loaded? + which backlight method does xrandr report?) that always work or always fail? Ok, let's summarise, sorry for the chaos: 1. Boot normally 2. Thinkpad acpi is loaded automagically 3. X starts via gdm 4. Brightness is reduced from 100% to 80%~70% 5. You set brightness back to top 6. You start zsnes or switch to a VT 7. Brightness goes back to 80%~70% 8. You change the backlight control via xrandr to *whatever* except kernel 9. Brightness stays at what you set That's the flow, the output of xrandr when the problem happens is: [EMAIL PROTECTED]:~$ xrandr --prop Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1024 x 1024 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm BACKLIGHT_CONTROL: kernel supported: native legacy combination kernel BACKLIGHT: 6 (0x0006) range: (0,7) 1024x768 59.3 + 85.0 75.0*70.1 60.0 832x62474.6 800x60085.1 72.2 75.0 60.3 56.2 640x48085.0 72.8 75.0 59.9 720x40085.0 640x40085.1 640x35085.1 After setting to native: [EMAIL PROTECTED]:~$ xrandr --prop Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1024 x 1024 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm BACKLIGHT_CONTROL: native supported: native legacy combination kernel BACKLIGHT: 0 (0x) range: (0,0) 1024x768 59.3 + 85.0 75.0*70.1 60.0 832x62474.6 800x60085.1 72.2 75.0 60.3 56.2 640x48085.0 72.8 75.0 59.9 720x40085.0 640x40085.1 640x35085.1 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Or I should say that I couldn't trigger the bug. Note that the missing thinkpad|ibm-acpi module seems to be the cause. I quickly tried your command but nothing seems to have changed, I tried running zsnes with each variation of the command but nothing happened. Shall I try without the module? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
