Monitor Doesn't Work with Video Card (worked in windows xp)

Asked by rickharman@yahoo.com on 2012-09-23

My graphics card only has a dvi out connector. I have a dvi to VGA adapter which will drive up to 2 monitors. My 17" LCD monitor can only take up to 1152x864. When I use that monitor solely, unbuntu requests 1280x1024 and my monitor gives me an error message. The only way I can get my monitor to work is to plug in an old CRT monitor along with my LCD monitor. I can then set the video to 1152x864 and both monitors work. I would like to get rid of the CRT. How can I tell unbuntu to use 1152x864 and nothing else. If it doesn't see my CRT, it goes into auto mode and screws up my LCD (no output image, only an error message). Any suggestions? Thanks!

Have you tried installing the proprietary driver, it may help.

I couldn't find a driver. I ran your command again with both monitors up and running.

Thanks for the link and spending some time on my problem. I tried the link, downloaded the theoretical driver, changed the permissions to r/w/e, typed sudo ./ati-driver-installer-9.3-x86.x86_64.run, typed in my password, and got "can't open". Any other suggestions? Thanks!

Is there a way to force a particular monitor resolution? It seems that ubuntu is automatically looking at the capabilities of the video card each time I start up the OS and trying to max out what the card offers.

There is the driver in the additional drivers app. Much easier

Can you help with this problem?
