You have been subscribed to a public bug: It is not possible to change the brightness on my Samsung p560 Laptop. The OSD shows up when using the brightness keys, but the brightness is not changed. I am not sure which package this problem is in. I can only change the brightness before booting ubuntu.
I have the Intel GMA4500 gpu, and this has been an issue since around 9.04. There is some information in this bugreport: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/338182, which describes a different issue. And an old bugreport set as wont fix: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/338173 Sadly any nvidia tools will not help. I currently have a clean install of: Distributor ID: Ubuntu Description: Ubuntu 11.10 Release: 11.10 Codename: oneiric Kernel: 3.0.0-12-generic-pae #20-Ubuntu SMP Fri Oct 7 16:37:17 UTC 2011 i686 i686 i386 GNU/Linux ** Affects: gnome-power-manager (Ubuntu) Importance: Undecided Status: New ** Tags: p560 samsung -- Cannot change the brightness on Samsung P560 Plavos https://bugs.launchpad.net/bugs/882434 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in Ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
