Bug Description

I noticed that Ubuntu computers may sometimes start up or resume from suspend and show many lines over the screen. Everything is fine except there are a bunch of black flickering lines over the screen that look like this:

                            _ _
                            _ _
                            _ _
                            _ _
                            _ _
                            _ _
                            _ _

This only happens sometimes, and when it does, a Ctrl-Alt-backspace or suspend and resume usually fixes it.
This has happened on a hardy computer and also on an intrepid computer.
I couldn't get a screenshot of this happening, when I screenshot it it looks normal, without these lines.

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

It's still happening in 8.10 with the latest updates!
This is probably the most annoying bug with running it on the laptop.

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:

  http://cdimages.ubuntu.com/releases/karmic/

If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as
well.

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.
