Hi, Same issue on emachines E725 Tried different options in grub2: acpi_osi=Linux, acpi_backlight=vendor and legacy, acpi=off and none work out.
Maverick: 2.6.38-020638-generic VGA: Intel Mobile 4 series IGP rev 09 When start ubuntu in 2.6.38, i cant see, but can go to gnome-command and launch the last command to setpci brightness to 77 and start to see !! and debug. Then, when close the lid with 2.6.38, backlight turn off and on, normally. Brightness control still not work. Only work setpci. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/518002 Title: extensa 5635z backlight dimming not working. works with setpci. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
