Public bug reported:
I have tried to dual boot Ubuntu 12.04 with a new laptop (HP 6z1000
Sleekbook) with the new AMD A-10 4655 APU (Trinity processor). The
performance was sluggish and had a watermark 'AMD hardware not
supported'. Using the recommended proprietary graphics drivers didn't
help, and removal of the watermark didn't help performance. The Ubuntu
experience is similar to a poor Windows Vista experience as far as
speed. The Windows 7 boot with this processor is very good-very close to
my previous experience with Ubuntu on a older laptop.
I tried 'Ask Ubuntu' and trialed the suggested 12.10 Alpha 2 build--I
also tried the Alpha 3 build. Both had a similar behaviour of a typical
purple Ubuntu splashscreen followed by an absolutely blank black screen
--nothing.
Any suggestions would be helpful.
