Actually I'm going to revise my last statement, even with Kernel 3.19.0-10-generic this issue is present ** Summary changed: - Switching from the TTY7 to a different TTY, causes Xorg crash + Intel Display i915 driver crashes, X1 carbon Gen 3 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1436590 Title: Intel Display i915 driver crashes, X1 carbon Gen 3 Status in xorg package in Ubuntu: New Bug description: - start ubuntu 15.04 and log in - use CTRL+AL+F2 to switch to TTY2.
