Look like same symptoms of bug #1510970 Disable window animations in Compiz reduces the frequency of the crashes. Use compizconfig-settings-manager for this tweak (sudo apt-get install compizconfig-settings-manager) I didn't run into this issue for several days after upgrading to kernel 4.3 from http://kernel.ubuntu.com/~kernel-ppa/mainline/ Please join me in testing this. ** This bug has been marked a duplicate of bug 1510970 Intel driver crashes on Ubuntu 15.10 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1512097 Title: Random crashes of X11 Status in xorg package in Ubuntu: New Bug description: This seems to happen when opening a new window. Just when the new window is going to open my screen goes black and I see the last lines of the boot process like I switched to the first virtual terminal. I wait a second or two and then I'm back at the login screen. Xorg crash log attached. The report 1509846 seems to be very similar to the behavior of what I'm seeing. I've tried turning off the animations in compiz now and will see how it goes.
