Ah, apologies, this is on Ubuntu GNOME, so I'm running gnome-shell and gdm. -- ⊨ Michael Gratton, Percept Wrangler. ⚙ <http://mjog.vee.net/> -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1632165 Title: modesetting driver unbearably slow on intel graphics Status in lightdm package in Ubuntu: Confirmed Status in xorg-server package in Ubuntu: Confirmed Bug description: After upgrading to Yakkey, I found the graphics performance of my MacBookPro12,1 (13", 2015, retina/hidpi display) became unbearably slow - switching workspaces, playing games, even just scrolling web browser tabs was visibly slower. The computer became constantly warm, and battery life dropped. Switching from using from modesetting back to the intel driver fixed these problems.
