I just installed Ubuntu 11.1 on my desktop pc. It was a clean install, no upgrading. I have a Samsung Syncmaster BX2450 connected to the PC. My problem is that I cannot make Ubuntu recognize my monitor - which is capable of more than 1024. I ran a shut down of lightdm, and ran sudo X -configure, but it gave me a "configuration failed". Nothing seems to work - any ideas?
