[Bug 197929] Re: Backlight adjustment no longer works on Thinkpad X61s
Hello, i came from same bug #176888. I have vaio VGN-FZ210CE, todays intrepid live cd i386. I confirm that after login, hotkeys do work, but backlight is not changed really, only bars in OS. after swtiching to any other backlight control, i have fully working backlight. all native, legacy and combination do work, kernel does not. I found also some problem, but applet from gnome-power-manager applet called gnome-brightness-applet. Until i change method using xrandr, it does respond, moves bar up or down. It does not however dim the screen. After xrandr, when i try raise or lower brightness using applet, all desktop hangs. I can still switch to text terminal or use control+alt+backspace to terminate X, but no keys or clicking work in any application, nor can i switch apps using alt+tab. I have simple compiz effect enabled by default. -- Backlight adjustment no longer works on Thinkpad X61s https://bugs.launchpad.net/bugs/197929 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 197929] Re: Backlight adjustment no longer works on Thinkpad X61s
Hi, Coming from #176888 which has been marked duplicate of current issue : Hardware : sony Vaio BZ11XN (Intel GMA X4500MHD). I confirm, on latest Intrepid (as of 2008-08-30), that the xrandr manual-call is *needed* to be able to use xbacklight. My Fn-keys are not working but this is another problem (#251665). As I stated in #173652 : 2 times out of 3, the rc.local call to xrandr seems to make some kind of race condition with gdm startup ; X do not start completely and the machine hard-locks : gdm starts, the screen blinks 2 or 3 times, then remains black (with backlight on) ; no response from anything (CAPS led is unresponsive, nor SysRq-reboot). Pulling the xrandr call out of rc.local and calling it in a terminal *after* GNOME session has opened is OK and makes xbacklight work everytime.
