Red Hat Bugzilla – Bug 232810
no widescreen resolution for intel g965 chipset
Last modified: 2007-11-30 17:11:59 EST
Description of problem: i can't get the proper resolution (1680x1050_60) with
the intel video driver (modesetting i believe).
I have an Intel DG965WH botherboard with the g965 video chipset and i'm running
Fedora rawhide with latest updates.
Version-Release number of selected component (if applicable):
Actual results: if i choose the i810 driver i can only get a stretched 1280x1024
resolution, while with the intel driver i get a 1400x1050_60 resolution wiche
does look odd on my screen (worse than 1280x1024).
Expected results: get the 1680x1050_60 resolution

The intel log looks like it's giving you 1680x1050. What does 'xrandr -q' say?
meanwhile i updated to the latest rawhide (and xorg-x11-drv-i810-1.6.5-14.fc7),
but still the same problem.
[filippo@localhost ~]$ xrandr -q
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 1680 x 1680
VGA connected 1680x1050+0+0 (normal left inverted right) 433mm x 271mm
1680x1050 60.0*+ 60.0
1280x1024 75.0 59.9

800x600 72.2 75.0 60.3 56.2
640x480 75.0 72.8 66.7 60.0
also gnome-display-properties shows 1680x1050_60 as current resolution, but it's
a lie: the desktop looks odd and the OSD of my monitor shows it's working at
As of xorg-x11-drv-i810-1.6.5-19.fc7, 915GM and all 945 and 965 chips will use
the intel modesetting driver by default. Please update, and test with that
driver, and reopen if you have further issues.
I have updated to the latest drivere and still I get the same problems. I'm
giong to upload a couple of files that i hope will make the problem clear.
It looks like that if I check the xorg log and xrandr -q everything should be
fine but it is not. Even if i take a screenshot and look it on a different PC,
it is a perfect 1680x1050 picture with all in the right place.
And when I tried this monitor on a different PC with a Nvidia videocard (with
fedora core 5) everything was perfect.

I had to choose the intel driver via system-config-display because without it
still load the i810 driver by default.

this is the osd info of the monitor showing it working at the wrong resolution

the resolution problem is clear looking at how i see the fonts: look at "Home
di filippo" in particular the first "o" and the "i". This is just an example of
how i see the whole screen.
Do the other resolutions available from xrandr work? For example:
$ xrandr --output VGA --mode 1024x768 --rate=60.0
Yes, I just tried some resolution and they do work. All of them work well except
they are stretched from 4:3 to 16:10, but looks fine.
It seems the problem is just with 1680x1050, maybe not but it's the only 16:10
resolution I can try.
I forgot to tell: the monitor is connected via VGA cable not DVI.
searching on the web, I found this bug:
I guess it's the same problem I have: same motherboard, similar monitor (same
native resolution, same brand) and same driver version.
For what it's worth, a new version of 915resolution was released on Monday which
supports the q965/g965. I'm running a q965 chipset (Dell optiplex 745) and was
having similar problems as documented here (using latest fc7 xorg). Now with
915 I can get 1920x1200, but any lower widescreen resolutions do not fill the
the problem is still there. Looking at freedesktop, a similar bug was "resolved"
for both a Samsung Syncmaster 226BW (bug #10545) and a 225BW (see
https://bugs.freedesktop.org/show_bug.cgi?id=10814), in the same way.
Unfortunately i am absolutely unable to modify and install the patch by myself.
Thus, if anybody could make a patched rpm or explain how to make one, i can test

Applying the attached patch i got everything working as it should. The patch is
obtained modifying those found on bugzilla.freedesktop.org for SyncMaster226
This is the first patch i ever "made", so probably it could be better or
I really hope there will be an update with the fix for fedora 7 soon after the
This patch has been integrated in F7 updates.
