I'm running Kubuntu Edgy. There are no error messages, other than KPowersave under the brightness settings tab simply giving the grammatically broken phrase, "Your hardware currently not support changing the brightness of your display." If you want more hardware information you're going to have to be more specific about what you want, I've already indicated it's an Inspiron 8000 and the video card driver being used, Rage128. More specifically it's a Rage 128 Mobility M4 32, but all Rage128's use the same xorg driver so I'm not sure if that helps.
If you tell me what to type into the command line and copy and paste here I can do that. -- Inspiron 8000 can't change brightness of display https://launchpad.net/bugs/49316 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
