Comment 26 for bug 519891

With 'nomodeset' I still get the garbled screen (and indeed tiny pixels
whenever I type something), but can fix it by using alt-sysreq-k.

Without 'nomodeset' I'm getting all vertical lines and cannot use my
system. Can't get past that with alt-sysreq-k or ctrl-alt-backspace.
Every once in a while it actually boots ok without the 'nomodeset' and
then Plymouth works ok, but at the moment I feel this is getting less
frequent.
Because I can't reproduce the behaviour without 'nomodeset' right or
wrong, I feel there is some issue to do with timing or a race condition
somewhere between the kernel and the radeon driver.
But I'm not a dev.

Updating Lucid twice a day. I'm not trying daily cd's unless I can't get
into my system even by booting into rescue mode.

cheers
