Comment 14 for bug 1284134

One other note: I am fully dist-upgraded on Trusty (no held back packages), but I cannot run the 3.13.0-16-generic #36 kernel because that exhibits the log in freeze of LP: #1289410. So at grub select "Advanced options for Ubuntu" and boot the 3.13.0-15.generic kernel. This allows me to log in and reproduce the bug.

@Brad thanks for trying to reproduce. Note that when I hit Alt to bring up the launcher, just type enough of "Terminal" to see it in Applications. Then I use the arrow keys to select the Terminal. I actually don't think it matters *how* gnome-terminal is started though. Same thing happens if you start it with Gnome Do. I just wanted to eliminate one non-standard package from the mix.

The problem clearly is that even just starting Emacs 24 corrupts something in X. Emacs doesn't even have to be running when you crash X, hence the suggestion to start it and then immediately kill it before triggering the bug.

Also @Brad: you could take a disk snapshot, then dist-upgrade away your held packages. It would then be easy to restore the disk snapshot if things break for you.
