[Bug 176888] Re: Backlight dimming not working in Hardy or Intrepid because of wrong XRandR BACKLIGHT_CONTROL setting
Vaio VGN FS840/W (915GM chipset) here, using the latest xserver-xorg- video-intel v2:2.4.1-1ubuntu10. I also have this problem with my backlight. After quite some time debugging the gnome brightness applet and gnome-power-manager, I realized gnome-power-manager is seemingly dependent upon xrandr. When running gnome-power-manager with --no-daemon and --verbose, I can see that it thinks the range for my brightness is (0,0). Xrandr also thinks the range is (0,0). If I change BACKLIGHT_CONTROL to legacy with xrandr, --prop will say my backlight range is (0,255), which is reflected in gnome-power-manager. Unfortunately, adjusting the BACKLIGHT with xrandr or the brightness applet does nothing (I have tried setting BACKLIGHT_CONTROL to native, kernel, legacy and combination with no results). When I run xbacklight, it returns "nan". If I write a value from 0 to 7 into /class/backlight/sony/brightness, my screen brightness will be adjusted. I understand this to be a function of the sony-laptop module however, not the video driver. The brightness applet doesn't use this method, so it is effectively broken. If I use the VESA driver, xrandr and the brightness applet work as expected. I assume this has to do with the intel video driver? -- Backlight dimming not working in Hardy or Intrepid because of wrong XRandR BACKLIGHT_CONTROL setting https://bugs.launchpad.net/bugs/176888 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
