Same problem here. I rarely had this problem previously with Ubuntu 14.04, but since updated to Ubuntu 16.04 I am suffering this issue very often.

The laptop has an intel HD Graphics 4400 video adapter, the one integrated within the Core i7-4510U CPU $ lspci ... 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) -- 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/1574266 Title: Xorg freeze [drm] stuck on render ring - gpu hanging too fast, banning To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1574266/+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
