XFree can't go higher than 640x480

i'm having slight difficulties getting the full cooperation from xfree

well it runs, which is allways a good thing

less good, however, is the fact that it stubbornly refuses any resolution above 640x480

i've succesfully had my monitor running 1024x768 in debian before i had to reinstall the whole darn thing after a CPU overheat, but xfree doesn't aknowledge that fact at all....

in fact it subtle enough to not give me any error messages, it just plainly refuses to do anything I tell it to do with the resoltuion via the XF86Config-4 file....

so could any one help me out convincing it that I am, in fact, not blind, and are fully able to use it in a higher resolution?

I've tried removing all resolutions other than 1024x768, it still runs in 640x480

I've commented out the hsync and vrefresh lines, (it detects HorizSync 28-33, VertRefresh 43-72 in dexconf) it still runs in 640x480

I've (succesfully) changed drivers from nv to nvidia and back, it still runs in 640x480

I've added 'option "NoDCC"' to the monitor and device section, it still runs in 640x480

i've run out of ideas, and the IRC channel isn't much help.... so anyone able to come up with some ideas/suggestions/explanations?

In a recent thread zero79 had exactly the opposite problem, but perhaps you could also try the solution that is revealed in the last post of the thread:

I had the same problem, by using a XF86Config generated by xf86cfg (the new graphical configurator). So I created a new XF86Config, using the old text-mode xf86config program.

It worked. The differences I saw between the two files were mostly the order in which Sections were declared.

Your problem is bad configuration of the xserver-xfree86

#dpkg-reconfigure xserver-xfree86

if you take the 'Advanced' option, MAKE SURE YOU HAVE THE CORRECT INFORMATION.

your horiz and vertical frequencies do not sound right. Make sure you check on the monitor manufacturer's site for the correct ones.

Generally a 17" monitor has something like this:
horiz = 30-70
vertical= 50-160

it varies with the size of the screen.
Do not use this unless this is your case. The final resolution is a mixture of the information you give debconf, your video card and its amount of memory, the monitor's frequencies, this is no guessing game.

If this is over your head, try the 'Medium' or 'Simple' options.

Xfconfig and xfcfg are slackware tools and are erased once you reboot, read the top of the XF86Config-4 file, it will say this.
