Re: Dell Optiplex and X not working ('no screens found')

Hello,

hopefully someone can help. I have a nice Dell box here
with an unidentified graphics card (ATI, but no idea what
else). It is the Dell Optiplex GX 280, and when saying I
want the 'ati' driver for X11 it just bombs out with the
message 'no screens found' and nothing else. The XF86Config
is identical to my old version on some box with nv drivers,
and I tried everything - from changing the 'Driver' from
'nv' to 'ati' up to redoing dpkg-reconfigure xserver-xfree86
from scratch, etc.

  
"lspci -v" might give you more info on your ATI card.

The following may or may not apply to the GX280s.

(At least some of) the GX270s had a BIOS that misreported the amount of video RAM available; the Linux kernel, believing the report, would only find 1 MB of video RAM, which was pretty much useless for any kind of decent screen resolution / color depth.

You might try dropping your preferred resolution/depth with "dpkg-reconfigure xserver-xfree86", and/or look in the XFree86 logs for a reference to how much video ram is being found. If it's only 1 MB, check your BIOS settings to make sure it's set higher than that, and if that doesn't solve the problem, look for a BIOS update from Dell (I had to have the Dell tech send me a beta version of a non-released BIOS to fix my issue).
