Do you see any events when you hit the hotkeys while running $ lshal -m ? Created attachment 257795 [details]
Output of 'lshal -m'
Thanks, Kirill. The events get reported as expected. This is a duplicate of bug #382855. *** This bug has been marked as a duplicate of bug 382855 *** Are you sure? 382855 is about function keys, but I can't change brightness even with software. Are you sure? Become root and go to $ cd /sys/class/backlight/$DRIVER where $DRIVER is a sub directory. Just do an ls in /sys/class/backlight to find out. In this directory you find a pseudo file called "brightness". You may run $ echo x > brightness to switch the brightness. Valid values for x range from 0 to $MAX, where $MAX is the value stored in /sys/class/backlight/$DRIVER/max_brightness . /sys/class/backlight is empty. Ah, alright. Reopening. Adjusting summary. Re-assigning to kernel team. It's /sys/devices/virtual/backlight I also always mix them up... Do you have this dir? No. There is no backlight directory in /sys/devices/virtual/ Still present in release. This problem affects me too (Lenovo 3000 N200). The brightness slider in the powerdevil profiles menu is not clickable. Brightness Hotkeys don't work either. lshal -m only recognises Fn+F11 (brightness up), Fn+F10 has no effect. Output of xev is keycode 212 (keysym 0x0, NoSymbol) for Fn+F11, again nothing for Fn+F10. /sys/class/backlight is empty. No directory named backlight in /sys/devices/virtual/. I've search bugs and found that: https://bugzilla.novell.com/show_bug.cgi?id=450307 https://bugzilla.novell.com/show_bug.cgi?id=456420 So I think that this bug is actual on all Lenovo 3000 series laptops. *** Bug 456420 has been marked as a duplicate of this bug. *** (In reply to comment #14 from Kirill Gagarski) > I think that this bug is actual on all Lenovo 3000 series laptops. And at least for the N200, it used to work (in 11.0) It worked in 11.0 on G410 too. Brightness fn-keys didn't work correctly (it wasn't so critical for me). In 11.1 betas all was fine (and fn-keys too) (In reply to comment #17 from Kirill Gagarski) > It worked in 11.0 on G410 too. Brightness fn-keys didn't work correctly (it > wasn't so critical for me). > In 11.1 betas all was fine (and fn-keys too) > Right. I can't say when exactly it broke but I think all of the alpha releases were fine... must have broken in late beta? @Kirill: Do you have other regressions, too? Like not correctly detecting "on ac" (and showing an empty battery icon)? Maybe this is all due to some ACPI stuff broken? 2Michael: No, power management works fine (except changing brightness, when AC adaptor is plugging on/off) I have try vanilla and default 2.6.27.8-9 kernels from http://download.opensuse.org/repositories/Kernel:/SL111_BRANCH/openSUSE_11.1/ . Brightness control works on vanilla kernel (but I have other troubles with it), but still doesn't works with 2.6.27.8-9-default. Hi I've the same problem (Lenovo 3000 N200), however lshal -m responds to the brightness-down key only for me (Fn+10), unlike another user reported, so this seems to be kinda weird too ... Still present after updating kernel to 2.6.27.19-3.2 Also present in 2.6.29 kernel from HEAD repo. This will be fixed in 2.6.30. We are still at 2.6.29, but Jeff will probably soon introduce .30-rcX. Keep an I on our latest kernel builds: ftp://ftp.suse.com/pub/projects/kernel/kotd/HEAD/x86_64 (or i586 dir) If you still want to give it a try before (you should be or get familiar with kernel compiling/installing then), download the latest vanilla 2.6.30-rcX kernel from kernel.org, take the .config file from our .29 kernel and just hit enter if you are asked for additional configs. Hmm, not sure whether it's already included in the current 2.6.30-RCx kernel, but it should be in the next one. Should be fixed mainline, but will probably not be backported. Please try a kernel from here: ftp://ftp.suse.com/pub/projects/kernel/kotd/master if you want to try this out. 11.2 should work then. Please reopen if it still does not work. Closing won't fix for 11.1. |
