Title:
  longstanding display driver bug elicited by xscreensaver or lightdm or
  chvt

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  i've been hitting this bug since natty or earlier.  today, as per
  usual, the evidence of the bug is that chvt no longer functions
  normally.  in today's case, two instances of xorg had been running,
  both crashed, xorg would not relaunch (immediately crashed again)(tho
  no trouble launching Xvnc), after the xorg crashes ctl-alt-F7 shows:
  "The system is running in low-graphics mode", ctl-alt-F8 shows all
  black, and the clear clue, ctl-alt-F1 shows the text you would expect
  to see there, but at the same time the mouse cursor is still being
  displayed and responding to mouse movement as if we were still looking
  at ctl-alt-F[78]!  same for ctl-alt-F[2-6].  when i hit this same bug
  on other days, the behaviour of ctl-alt-Fn will be peculiar in unique
  bizarre ways.

  i tried to submit this bug via ubuntu-bug (in 2 or 3 "screen" windows,
  then killed them all, then tried one more time), then zipped up the
  apport log, the Xorg logs, the single /var/crash/*Xorg* i found, and a
  process list.
