[Bug 1048230] [NEW] display freezes


Public bug reported:

(compiz may or may not be the right place for this - please relocate if

When running unity, every now and then the display will freeze. The
image remains visible on the screen, but is static - the cursor can
still be moved around the screen, and ctrl+alt+F1 still brings you to a
virtual terminal. When running top from tty1, it can be noted that the
compiz process is still running, also no crashes appear in /var/crash/*.
The only way to resolve this seems to be a reboot. The issue started
occurring about 2-3 weeks ago. From memory I have encountered this
lockup maybe once or twice whilst only using the internal monitor of the
netbook. When an external monitor is connected however, within a few
minutes the display will freeze. The machine in question is a dell mini
9 using the i915 driver.
