No, the issue didn't occur in Xenial, which defaults to the intel driver. (The intel driver doesn't have these issues.)
Just to be clear - it is possible that the issue is resolved with the later BIOS, but I won't know until I can test the known bad configuration again. (Unfortunately, I can't use the later BIOS full- time thanks to the brightness issue.) In general, the modesetting driver works fine (and it doesn't tear on the external display when scrolling, unlike the intel driver, which is nice). Modesetting does struggle a bit when changing resolutions, and X slows down for a while after the resolution changes. It usually speeds back up within say 10 seconds, but sometimes the slowdown persists. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1618423 Title: Modesetting driver cannot handle different display resolutions for two monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1618423/+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
