[Bug 355508] Re: [i945gm] Kubuntu: corrupt login screen and X freeze on startup when using desktop effects (UXA bug)

 

I've just done an install of kubuntu karmic alpha 3 from the latest
packages and have experienced the following issues;

Font sizes at login screen are huge (~72 points or so)
During login, screen/cursor visibly freeze every few seconds
On login, font sizes are still huge
Taskbar at bottom is drawn without corruption
Clicking on anything makes a window appear (although there is a brief freeze as the window is drawn), but the contents are entirely corrupted (mostly horizontal banding lines) - cursor is not visible when it overlies corrupted area

I would attach screenshots and configs, but the laptop is utterly
unusuable - nothing coherent is visible on the screen, and for some
reason ctrl-alt-backspace won't work to let me drop to a terminal so I
can tinker with xorg.conf. To me this sounds exactly like a
manifestation of the above issue, but I don't have any way of checking
my config and/or changing any settings. Can anyone confirm this? Just to
reiterate that this is a completely standard install on first boot, and
no customisation has been done.

Hardware is an HP nx7400 laptop with the i945 GM. Going to try the same
hardware with Debian tonight after I try and get some pics of what the
screen looks like. If this really is endemic to i945's it's a real
showstopper IMHO.
