So I can confirm that adding the extra modeline works, eg I now have 2560x1440@60 Hz both appearing in xrandr and working on the laptop monitor using the modeset driver.
(There's a separate bug for the modeset driver whereby if you change the mode, eg from 1920x1080 to 2560x1440, the new screen only uses the top 1920x1080 display space - except, curiously, for the unity launcher and top bar - but once I restarted lightdm, the new resolution works fine.) No, I hadn't heard of quilt before. I'll check it out. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1606103 Title: modeset driver is missing some modes that the intel driver (and Mir) has To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1606103/+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
