Hi all,
I've installed Sarge on a Dell Optiplex GX270 at work, and everything is
running great except I can't get a decent refresh rate in X. In windows
I could set the resolution to 1152x867 (or something like that) with a
76Hz refresh rate which was kind on my eyes and gave me a decent amount
of screen real-estate, but I can't seem to do this under X at all (nor
even get past 60Hz at 1024x768).
I'm using the i810 driver with agpgart and dri. I've tried with
ModeLines as detected by Knoppix (which also fails to work at a decent
res) and without (leaving X to auto-detect) without any difference. The
only thing in my XFree86.0.log that sheds any light is the lines:
(II) I810(0): Monitor EDID v2 checksum failed
(II) I810(0): XFree86_DDC_EDID2_RAWDATA property may be bad
lspci lists my graphics card as:
0000:00:02.0 VGA compatible controller: Intel Corp. 82865G Integrated
Graphics Device (rev 02)
My monitor is a Sun CM751U (or SUN0564 from DDC).
Does anyone have any ideas? I'll provide my complete XFree86.0.log or
whatever if need be.
Many thanks,
Chris

This might be a soloution to your trouble.
Take a look at your XF86Conf-4, at the section "Screen". You have got the
depths listed but you seems to not having the "modes" listed for the
proeriate depths.
It sould look somthing like this:(the section in my XF86Conf-4)

Swap my GeForce with your Generic Video Card and my ___:ffff with your Generic
Screen.
Beware! If your screen was autodetected, as it looks like, you have got a low
HorizSync and VertRefresh rate. I am a bit unsure, but my screen is 30-70(HS)
and 50-120(VR) and I am not alowed to have more than 1280x1024 at 60Hz,
neither in linux or windows. It looks like your Windows has gone a bit far if
you have had 1152x867 at 76 Hz. Try 1024x768 at 72Hz(or a bit more).
72 Hz is the lower limit for your eye to registrating flickering. Everything
above will look "solid".

Hi Helge,
I *had* added the Modes lines before, but I took them out in case it
wasn't exactly 1152x864. With them out the graphics settings can go all
they way up to 1600x1200@60Hz, but that's positively tiny! ;-)
I tried fiddling with the VertRefresh / HorizSync and extended them to
values I found by searching google for my monitor, especially since I
found the following in my log:
(WW) I810(0): Generic Monitor: Using default hsync range of 28.00-33.00kHz
(WW) I810(0): Generic Monitor: using default vrefresh range of 43.00-72.00Hz
I added these values:
HorizSync 30.00-92.00
VertRefresh 40.00-130.00
I thought we were onto something but still no luck. Depite being
properly detected (see log snippets below), they don't work.

At least now it seems I get a decent refresh rate (85Hz) at 1280x1024,
which will do me just fine, but I don't actually know until I get to
work tomorrow and have a real look. Would be nice to have 1152x864
though, since it's not too small...
Many thanks,
Chris
