[TEN <1341270@xxxxxxxxxxxxxxxxxx>]

The following from a resumed-to Ctrl-Alt-F2 text console results in the
same sort of crashes, so the cause seems to be something other than
(only) the display auto(re)detection:

chvt 7
xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode DFP-1 "1920x1080_60.00"

The final crash hit so hard it corrupted all of /dev/sda's file systems
(requiring to press F on each to even reboot).

Looks a lot like https://bugs.freedesktop.org/show_bug.cgi?id=35648 back
with a vengeance.

Title:
  Ubuntu 14.04 freezes on resume from suspend: GeForce GT 520 GPU with
  nouveau or proprietary nvidia-331 drivers, even when booted nosplash
  noquiet

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Generating individual reports as requested by Christopher M. Penalver
  and Chris Bainbridge in
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283938 via
  "ubuntu-bug linux".

  After forcing switch from nouveau to nvidia-331 (a sad story in itself
  as the System Settings pretend to handle that:
  https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-
  drivers-331/+bug/1315156) at least apportcheckresume does catch the
  issue as attached, but after Continue gives no further indication what
  data has been sent where (if at all) and how it may be commented or
  complemented, i.e. nothing opens in the browser, only local password
  prompt(s).

  Sometimes the screen shows a blinking text console mode prompt and the
  NumLock key can still turn its LED on and off for a few seconds under
  nivida-331 before the machine freezes with fans running after resume,
  while nouveau would even permit Ctrl-Alt-F1 occasionally (but then has
  other log-flooding issues as indicated at the prior link).

  Not being able to resume after suspend has kept my Ubuntu 14.04 LTS installation unusable for 3 months already.
  This is a recurring issue already exhibited by 12.04 LTS, affecting numerous systems even back then (cf. references from https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/999638) on kernels before 3.2.0-25-generic-pae, as well as with Intel graphics - but in spite of the regression users continue to be isolated into individual bugs (hardly cross-linked with the major ones) and sent through BIOS upgrades and mainline kernel testing while the bugs in spite of their Heat continue to lack the requisite Importance and Assignment (or orchestrated testing for potential Mode Setting implications).
