[Bug 787821] Re: Random X server crashes on keypress using natty

[Shinoda]

Like TiGR wrote in comment #28, this only happens to me once on every
boot, usually a few minutes after logging in and typing something, for
instance in Pidgin. At a random press of the Enter key, X restarts
before the message I wrote is sent, meaning the key stroke never reaches
the application, as far as I understand it. By "X restarts" I mean
suddenly all running applications are killed and Ubuntu goes back to the
graphical login prompt.

Oddly enough, if Audacious was running before the crash and I relaunch
it afterwards, it warns me that another instance of itself may already
be running. Ignoring the warning allows Audacious to run properly. Maybe
a lock file of some sort the application wasn't able to release or
delete before X crashed?

This issue started happening around May or June 2011, if I recall
correctly, and never happened in previous Ubuntu versions (using 11.04
at the moment).

Title:
  Random X server crashes on keypress using natty

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  Binary package hint: plymouth

  I'm on Natty 64 bit and I'm experiencing "random" X crashes on
  keypress.

  The bug surely happens on pressing enter or "2" (i don't know about
  other keys), however it does not happen on the first time they are
  pressed but randomly.

  When X restarts on the terminal a bunch of characters appears as If
  some keycodes where misinterpreted and echoed back to screen (note
  that the characters are not the ones on the pressed keys).

  I'm using LVM with encryption and proprietary Catalyst drivers on a
  switchable graphics (Intel / ATI) configuration.
