The spec sheet for that monitor doesn't seem to show these frequency/resolution pairings, but they should indeed be possible given the scan ranges its capable of, assuming its efficiency hasn't dropped significantly with age. I wish I could confirm this without reproducing it myself, hopefully this gets fixed, nouveau should be capable of determining safe refresh rates. If you're feeling up to it, you can specify those modes manually: http://ubuntuforums.org/showthread.php?t=83973 and bit more recent: http://askubuntu.com/questions/59621/how-to-change-the-monitors-refresh-rate
I've never attempted this myself, so if you run into trouble I'm sure the folks in #ubuntu on IRC can help you out. ** Tags added: hw-specific -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/910072 Title: DELL P790 missing crucial refresh rates for critical resolutions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/910072/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
