Thanks David. Due to your hint using the ppa-Kernel I went off to install this one:
r...@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 r...@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: r...@sofa:/etc/default# grep nomodeset grub GRUB_CMDLINE_LINUX="nomodeset" r...@sofa:/etc/default# to avoid a EDID checksum error and to prevent the screen resolution being throttled to 1376x768 -- ATI radeon KMS driver - gpu lockup https://bugs.launchpad.net/bugs/568605 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
