Red Hat Bugzilla – Bug 223773
Xorg default config unusable on GeForce 6200 / Acer AL1716 monitors
Last modified: 2008-08-02 19:40:34 EDT
Description of problem:
Using a nVidia NV44 [GeForce 6200 TurboCache(TM) rev. a1] on an Intel DP965LT
mainboard (version AAD41694-206) leads to unsupported video modes on an Acer
AL1716 monitor. The issue is reproductible in Fedora Core 6 as well (both
default packets and updated ones, as to 20070122).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install RHEL5 Beta 2 / FC6 on a system having a previously described hardware
2. reboot the system after install either in runlevel 5 or runlevel 3 and
'xinit' or 'startx'.
Actual results: The monitor displays "Invalid input mode".
Expected results: on screen image at the required resolution (1280x1024).
Additional info: Output is OK in RHEL4-ES-U2; installing NVidia-provided drivers
on RHEL5 Beta 2 / FC6 appears to solve the problem. I have also tried to
manually edit /etc/X11/xorg.conf and define the vertical refresh freq. It
appears to work, although the frequencies displayed by the monitor are quite
different than the ones set up in xorg.conf (e.g. 60 Hz vert. / 64 kHz hor.
despite having set Mode "1280x1024@75Hz" in xorg.conf).
Can you attach the X log from the failed startup please?
