We are sorry that we do not always have the capacity to review all
reported bugs in a timely manner. You reported this bug some time ago

Do you still see a problem related to the one that you reported when
using a currently supported version of Ubuntu? Please let us know if you
do otherwise this report can be left to expire in approximately 60 days
time.

Title:
  Xorg freeze when switching from graphic  to text konsole

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  When changing from graphic X11 Window (screen 7) to an text konsole (screen 1 
- 6) everything ok. 
  When changing back tty1 to graphic system hangs. 
  Mouse can be moved, but click doesn't have any effect. 
  Changing back to text konsole is working, but takes a long time (~ 1 minute).
  In syslog an error message is logged. (see attached file kernel.dump)

  Error in syslog could be reproduced on 2 lenovo thinkcenter m91p and
  one fujitsu esprimo c700, all of them with intel graphic.
