Public bug reported:
Screen either becomes garbled or goes grey/white or multicoloured
vertical stripes associated with complete system freeze that requires
holding down the power button down until system powers off. When the
screen becomes garbled the mouse pointer is often still visible on top
of the garbled image.
The frequency and cuase of the freezes varies but when using firefox
opening a new tab often induces it.
I have experienced this under 11.10 64 bit install using both a standard
setup and after trying the xorg-edgers ppa. I have also repoduced the
problem using a Mandriva 2011 live cd. I dual boot the machine with
Windows XP and that works without issue.
My laptop is a Compaq NX6125 with a ATI Radeon Xpress 200M graphics card
which uses 128Mb of system memory. I am also using the default radeon
driver.
