This seems to be related to the fbdev driver. After I installed the ati-fglrx driver, I can change the brightness level even if I switched to console before. Attach /etc/X11/xorg.conf and /var/log/Xorg.0.log. Created attachment 160094 [details]

Did this work before with fbdev driver? I'm not sure, because the whole brightness stuff (thinkpad_acpi and kpowersave) was broken before. If I find some time I can install an alpha version if this helps? IIRC it works in 10.2. No need to install an alpha version. You think it worked in 10.2. Were you using fbdev or fglrx on 10.2? I did a testrun on my private workstation (openSUSE 10.2). It works with both, fbdev and fglrx. In openSUSE 10.3 it only works with !fbdev. evtest /dev/input/event0 doesn't show any keycodes when pressing these keys, but "showkey -s" shows the following scancodes: brightness up: 0xe0 0x54 0xe0 0xd4 brightness down: 0xe0 0x4c 0xe0 0xcc After restart of fbdev driver brightness control works again, so something seems to be wrong in the VT switch code of fbdev driver? minor issue. Most users are not satisfied with fbdev driver anyway ... Well, you have to use it until the ati-fglrx is usable :( Btw: you know that thinkpads change the brightness in hardware? So it seems that fbdev overwrites some values... The fbdev driver does not reset any brightness bits of the GPU. This issue can only be fixed by a proper native graphics driver like radeonhd. Possibly you get better results with using the vesa driver. If it worked with 10.2, you were lucky. I can't see a reason for this. Please understand WONTFIX as CANNOTFIX and please give radeonhd driver at least a try. Thanks. |
