                    xserver-xorg-video-ati 1:6.14.0-0ubuntu4
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: s.j.turner at uqconnect.net


I am forwarding this bug from https://bugs.launchpad.net/ubuntu/+bug/761723

The original reporter has the following hardware"

GraphicsCard:
 ATI Technologies Inc Mobility Radeon HD 3650 [1002:9591] (prog-if 00 [VGA
controller])
   Subsystem: Toshiba America Info Systems Device [1179:ff62]
LiveMediaBuild: Ubuntu 11.04 "Natty Narwhal" - Beta amd64 (20110413)
MachineType: TOSHIBA Satellite A300D

The original bug description is:

After upgrading from Maverick to Natty, this machine (now running via a Live
CD) becomes unbootable. The boot process seems to start off OK, but then
finishes with an "aubergine screen of death" with a solid blue line at the top
(see attached photo). I have tried the upgrade via both apt and the live CD but
the two methods fail in the same way. Trying to boot via the fail safe mode
also results in a system freeze (black screen of death this time!)

Also:

Tried again this morning, with the newly released final released. I was very
disappointed to see that the problem remains. I wonder how many first time
Linux users will have this as their very first Ubuntu experience.

Another user reports what they believe to be the same problem, saying "This
also impacts me. Here's the relevant part of dmesg:"
