Problem enabling higher resolutions on LCD


New V7 22” LCD R22W02 monitor with 30-82KHz horiz freq, 56-75Hz vert range and WSXGA 1680x1050 max resolution. Cannot get more than 1280x960 using System-Preferences-ScreenResolution option. AMD system. Have installed the nVidia accelerated graphics driver (restricted drivers) and had video running great at a lower resolution with old AOC crt monitor, which was in system, when Feisty first installed. After searching I have been trying to rerun the Autodetect script to find the new monitor as described in the “Ubuntu Documentation” “FixVideoResolutionHowto” at “https://help.ubuntu.com/community/Fi...solutionHowto”. Have entered the lines below as instructed,
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
sudo sh -c 'md5sum /etc/X11/xorg.conf > /var/lib/x11/xorg.conf.md5sum'
sudo dpkg-reconfigure xserver-xorg
But the resulting reconfigure process wouldn't run to completion. So I manually added the horiz and vert refresh lines to the Monitor section of my xorg.conf file as described in the second method of the Howto, saved and restarted X, logged in, checked and my available screen resolutions are still limited to 1280x960 for widescreen. The two new lines do show up in my xorg.conf file as shown below (with the Identifier and Option lines still the same as old),

Option "DPMS"

VertRefresh 56-75

At a loss where to go from here. Have already done complete reload of Feisty once after really messing up video, when learning how to install the glx-new nVidia driver. I'd hate to mess up again sorting the monitor. Can I somehow enable the higher resolution choices? I know at least some higher resolutions are possible for Intel chipsets, but I have AMD. Or is there a LCD setting, which might enable them? -just surmising here. Many thanks.

I had a similar problem.
What I did was remove the resolutions that I did not want and added what I needed.
Then re-booted.

Thank you!!

Many thanks! I took your advice and had a look at the resolution entries in my xorg.conf file. Backed the file up, then with vim deleted the entries in the original and substituted 16:10 aspect ratio values found by googling widescreen resolutions. Saved file, did ctl-alt-del to restart X, logged in and I now have all of the higher resolution settings up to 1680x1050. Have included the mod to the xorg.conf file below. These were the only changes, which I had to do.
