[Bug 568605] Re: ATI radeon KMS driver - gpu lockup

[Thomas Antepoth]

Thanks David.

Due to your hint using the ppa-Kernel I went off to install this one:

root at sofa:/var/log# uname -a
Linux sofa 2.6.35-18-generic #24~lucid1-Ubuntu SMP Mon Aug 23 04:49:33 UTC 2010 x86_64 GNU/Linux
root at sofa:/var/log#

Overall scrolling performance feels somewhat improved and the first link
did not lock up my machine which it did quite reliable before installing
the 2.6.35.

The second link provided did also not lock up the machine but while
building up the page in the browser there were some interruptions in
screen updates (e.g. clock seconds did not advance, mouse pointer froze
for several seconds, rendering stopped amidst the picture).

In order to install that kernel I had to set:

root at sofa:/etc/default# grep nomodeset grub 
GRUB_CMDLINE_LINUX="nomodeset"
root at sofa:/etc/default#

to avoid a EDID checksum error and to prevent the screen resolution
being throttled to 1376x768
