1280*760


May be it's sounds fun but I need the command to change my resolution to 1280x760... I have set my 3d card drivers through xorgconfig command. My 3d card is ati radeon xprees and I think i have done it in the right way.. But i have not the 1280x760 selection in my list.. so i am wondering if is possible to change my resolution through bash!

Thanks in advance,
Cyhaxor

The way I have always done it is to edit /etc/X11/xorg.conf and find the section for Screen. You will see your available resolutions, just add the ones you want that your monitor/video card can handle. It should look similar to below. After you edit you will have to restart X to get the new options. You can do this by rebooting, or just close out of all running X apps and then hit 'CTRL+BACKSPACE' this will close and restart X.

You have several display settings with different modes. My solution has alway been to add the mode I want to each section. Then after I restart X the option is there to change the resolution. So in each mode line add "1280x760". Also, I am sure you thought about this but just in case, it is best to copy your xorg.conf to a backup just in case. If the display does not work after restarting X you can always replace the original.

Check /var/log/Xorg.0.log for warnings or errors, and what resolutions/video modes were dropped (and why), and what was then used (and why). The logfile will very probably tell what's going on, if you take the time to read the relevant parts of it..it's a good idea to add the resolution you want to each colour depth just in case, but that won't solve the problem here I guess. Of course it could be that depth 24 is rejected here for some reason, but I doubt it..

Some video modes, colour depths, screens and/or video cards just don't want to play it nicely. Others don't do it unless you configure them just the right way, and some do it more or less painfully..but reading logfiles usually helps deducing what actually went wrong.
