Can't get 1280x1024 on LCD
I just installed a new XFX 7600 GT XXX edition. It's a big improvement over the onboard Radeon Xpress 200 and the buggy fglrx driver.
Unfortunately, I can't get it to drive my LCD at it's native 1280x1024. It only goes up to 1024x768. With no modelines in xorg.conf, the log file says "No valid modes for "1280x1024"; removing." So, I added "Modeline "1280x1024_60" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync" from the output of gmt to the config file and changed the default mode to 1280x1024_60. Now the log says, "No valid modes for "1280x1024_60"; removing."
/usr/sbin/nvidia-xconfig -query-gpu-info correctly shows my monitor as 1280 x 1024.
