CrunchBang Linux

I just installed the new Debian-based #! on my FSC Amilo Pro V2035.
However, the resolution is set to 1600x1200 (as I find out when hitting the menu option "Adjust with grandr") at 0.0Hz, and this is wrong. The monitor can only handle 1280x800. In the list of available modes in grandr there's several options listed, one which is "1280x800 61.0Hz". Trying this, the screen is filled with artifacts and it seems like it somehow shows the same desktop three or four times, side by side, all scrambled. Pretty useless.

So I guess I have to edit xorg.conf to get the correct resolution, but I can't seem to find it at /etc/X11... Am I missing out on something?

Also, doing that "lspci" thing in the terminal tells me on the last line that:
01:00.0 VGA compatible controller: VIA Technologies, Inc. CN700/P4M800 Pro/P4M800 CE/VN800 [S3 UniChrome Pro] (rev 01)
...and as far as I recall the onboard graphics is some kind of SiS-deal (with a 64MB memory limit). So does that need fixing somehow?

And yes, I am still somewhat of a newbie on these Linux matters.

Update: http://forums.debian.net/viewtopic.php?f=30&t=61573 told me what I needed to know.
Had a look-see over at http://www.linuxquestions.org/questions … on-444052/ and figured out what to add to my xorg.conf.
Basicly, I got the system to generate a new xorg.conf, and then I copied it to /etc/X11, added depth and resolution, saved, rebooted... and smiled.
