[Bug 407793] [NEW] [i865g][Karmic Alpha 3] X corruption and freeze when clicking "Other" on GDM login screen

 

Public bug reported:

Binary package hint: xserver-xorg-video-intel

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System
-> About Ubuntu.

michael@kiwi:~/dri_debug$ lsb_release -rd
Description:	Ubuntu karmic (development branch)
Release:	9.10

2) The version of the package you are using, via 'apt-cache policy
packagename' or by checking in Synaptic.

michael@kiwi:~/dri_debug$ apt-cache policy xserver-xorg-video-intel
xserver-xorg-video-intel:
  Installed: 2:2.8.0-0ubuntu1
  Candidate: 2:2.8.0-0ubuntu1
  Version table:
 *** 2:2.8.0-0ubuntu1 0
        500 http://ca.archive.ubuntu.com karmic/main Packages
        100 /var/lib/dpkg/status

michael@kiwi:~/dri_debug$ apt-cache policy gdm
gdm:
  Installed: 2.27.4-0ubuntu6
  Candidate: 2.27.4-0ubuntu6
  Version table:
 *** 2.27.4-0ubuntu6 0
        500 http://ca.archive.ubuntu.com karmic/main Packages
        100 /var/lib/dpkg/status

3) What you expected to happen

The screen would display a "username" field and allow me to type in my
username.

4) What happened instead

The screen displays the username field, but black boxes (corruption?)
appear above and below it, and the computer stops responding to all
keyboard input, with the exception of Alt-SysRq keys. Hitting Caps Lock
does NOT make the respective keyboard LED go on, but hitting Num Lock
does. It is possible to move the cursor with the mouse, but clicking
does not do anything.

--- As per https://wiki.ubuntu.com/X/Troubleshooting/Freeze

# When did you first notice it? Did you change any settings (Desktop
Effects?) or update your system prior to first noticing it?

Freezes have generally been intermittent on this machine since Jaunty,
but it hasn't been possible to reproduce with any sort of consistency.
Doing a clean install of Karmic Alpha 3 causes this particular freeze to
always happen when doing these particular steps.

# What frequency does it occur? Just once? Hourly? Daily?

Occurs every time I start the computer.

# Try to determine actions which reproduce it or make it more/less
likely to reproduce.

Always reproduceable by clicking "Other" in gdm.

-- As per (https://wiki.ubuntu.com/X/Reporting)
