[Jaunty] Resolution 1920x1200 not available after installing Nvidia driver 173

[Ari Torhamo]

Binary package hint: xorg

I installed Ubuntu 9.04 (Jaunty) to a PC that has a 24" LG W2452T monitor and
an Nvidia Geforce FX 5200 graphics card. After the installation the resolution of
the monitor was set correctly to the native 1920x1200.
After installing the proprietary driver Nividia 173, resolution was changed to 1600x1200. This was also the highest available option in the display settings. Uninstalling Nvidia 173 didn't bring 1920x1200 back, so the system is now stuck with 1600x1200 as the highest setting available.

I might add that I got 1920x1200 to work in the same computer with Ubuntu 8.10 (Intrepid). There was some hassle, perhaps changing between the drivers a couple of times and a couple of reboots, but no tweaking of xorg.conf, etc.

There probably is no connection, but Windows doesn't get the resolution right either. There the desktop is too wide to fit into the display area, part of it being left outside, although the driver (latest, from Nividia web site) says that the resolution is set to 1920x1200.

I found a fix for the problem. I added these two lines to Section "Device" in xorg.conf:

Option "ModeValidation" "NoMaxPClkCheck"
Option "UseEdidFreqs" "on"

This solution was presented here:

I have the same card and the same problem but i am stuck at a 640x480 resolution. Could not solve the problem. Can you be more specific on the solution you took?

Thanks

[Kemel Zaidan aka Legendario (kemelzaidan)]

those lines on xorg.conf didn't work for me.

Had the same problem. The two lines, poster #3 mentioned, did the job for me.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

Unfortunately I haven't noticed any messages that may have been sent to me afterJune 2009 concerning this bug report. I don't currently have an access to the computer which the report is about. That may change later, and in that case I will update this report. Thanks!
