Description Lars G 2005-04-24 04:59:06 EDT
From Bugzilla Helper:

Description of problem:
somehow the 1400x1050 resolution is broken with the newest xorg version for my crt.
when i use 1400x1050 res. i only get 1280x1024 60hz. 
other resolutions work ok.
as a temp. fix i use now the modeline
Modeline     "1400x1050" 179.26 1400 1504 1656 1912  1050 1051 1054 1103 +hsync +vsync in the "Monitor" section of my xorg.conf.
with this i'm able to get the right display (85hz) but the monitor osd still tells it is 1280x1024 but
it's really a 1400x1050 res.

relevant part of my xorg.conf:

Thanks for the report.  For users who are experiencing problems
installing, configuring, or using the unsupported 3rd party
proprietary "nvidia" video driver, Nvidia provides indirect
customer support via an online web based support forum.  Nvidia
monitors these web forums for commonly reported problems and
passes them on to Nvidia engineers for investigation.  Once
they've isolated a particular problem, it is often fixed in
a future video driver update.

The NVNews Nvidia Linux driver forum is located at:


Once you have reported this issue in the Nvidia web forums,
others who may have experienced the particular problem may
be able to assist.  If there is a real bug occuring, Nvidia
will be able to determine this, and will likely resolve the
issue in a future driver update for the operating system
releases that they officially support.

While Red Hat does not support the proprietary nvidia driver,
users requiring technical support may also find the various
X.Org, XFree86, and Red Hat mailing lists helpful in finding

X.Org mailing lists:

XFree86 mailing lists:

Red Hat mailing lists:

Setting status to "NOTABUG" (unsupported).
Comment 2 Lars G 2005-04-25 08:36:15 EDT
have to add that i get the *exact* same behavior with the open "nv" driver.
so i guess it has something to do with this change:

* Fri Apr 22 2005 Soren Sandmann Pedersen <sandmann@redhat.com>
- Make old custom-modelines RHEL4 only. Add .laptop-modes.patch with
  support for various weird laptop resolutions.

so i'm reopening this one

Comment 3 Lars G 2005-04-25 12:30:32 EDT
any particular reason why this is set to closed notabug ?
