I am assuming you really do have an ADI GD-790 monitor ?
Either that or there is something going horribly
wrong with the nv
driver.
I thought modern X could read the monitor's EDID which should have at least one detailed video timing for the preferred mode. This is particularly important for LCD screens which expect lower pixel clocks than the traditional CRT timings for the same modes.
Yes it is an ADI GD-790 monitor
Adding 'HorizSync 30.0 - 100.0' to the Xorg.conf file did the trick. It boots fine now into Desktop and I can change resolution via Desktop - Prefences - Screen Resolution. thanks wayne & tim
Before that fix the desktop resolution the 1600x1200 85Hz setting gave a sort of virtual desktop. i.e not all the desktop was shown on screen but when the mouse reached the screen edges the desktop scrolled to reveal more. that exact resolution option isn't available now. only 1600x1200 75Hz. Was that scrolling a bug or a separate feature of Gnome thats now turned off?
Best wishes
