xorg i810 driver and 24 bit color depth
This stupid thing defaults to 16 bit color all of the time. Can someone help me out on this. The video card is a intel 845gm. Using vesa driver gives correct 24bit color depth.

Re: xorg i810 driver and 24 bit color depth
Do you have any 24 bit modes in your BIOS defined? i810 reads available modes from the BIOS. Sometimes you need to patch it with 915resolution (it's in the community repo). Also make sure that it has enough VideoRam for this resolution and color depth.

Re: xorg i810 driver and 24 bit color depth
no idea what just happened here, I started installing some random distributions, checking if they would work.
opensuse was a no go, ubuntu feisty did the trick. As I kinda dislike ubuntu I started installing Arch again after a night of sleep.
I installed 915resolution, however I did not do anything with it besides a '915resolution -l', so it has changed nothing. Guess what, I'm on 24 bits now 
Is it something ubuntu did with my bios, or is it just a miracle, I don't know, but it's working. Let's hope it stays this way!

Re: xorg i810 driver and 24 bit color depth
The BIOS can't be patched permanently with 915resolution you need to add it to daemons in rc.conf (which just patches BIOS with every boot).
I guess in the whole process you simply updated arch drivers (or something else from xorg packages) to the latest version and it just worked out of the box :-)
Anyway, it's good that it works now.

Re: xorg i810 driver and 24 bit color depth
I guess I have found the common factor, it's kde. Playing a video in gnome gives me 24bit colors, playing a video in kde (most of the time (not always!) even with kmplayer under gnome.
Well I'm perfectly happy to use gnome, but wtf is kde doing with my display ? :S
