Bug Description
This bug report started as a comment in the thread associated with bug 38915 (https:/
Problem: 7 out of 10 times my PC freezes when I logout from my Ubuntu session. I get a black screen and my LCD says that there is no video input. Ctrl+Backspace and Ctrl+Alt+Del keyboard salutes don't work, and remote ssh sessions into my machine die; the only way out is a hard reset of my PC. As far as I can say nothing is logged in either the syslog or the X log files.
Environment:
* Ubuntu 8.04 running on an ASUS P5E-VM mother board with the Intel G35 (3500) chipset and 2 GB of RAM.
* My home directory is not local but NFS-mounted from another machine running Ubuntu server 8.04.
* My xorg.conf file is the barebones one created by running "sudo dpkg-reconfigure -phigh xserver-xorg"; it
has no mention of a specific driver or monitor details; I guess these days everything X-related is found
dynamically as X takes over.
* My PC was upgraded from Gutsy to Hardy. While on Gutsy, my video chipset was not well supported, I
couldn't enable desktop effects for example, but I never experienced these freezes.
Things that I have done include:
1. Booted Hardy with the Feisty kernel. No changes.
2. Created a brand new user with a local home directory (not NFS-mounted) and tried login in and out. No changes.
3. Tried turning off desktop effects. No changes
4. Modified my xorg.conf file to force X to use the VESA driver ... success, no more freezes after logout.
Of course with this last option I get a sub-optimal desktop but this makes me conclude that the problem is X-related. My first call would be to blame the new Intel driver in xorg.

Same problem with me (dell d505, intel 801 card). acpi-support, as discussed in /bugs.launchpad .net/ubuntu/ +bug/38915/ comments/ 61 hibernate. sh from command line. This gave me some freezes as well and a clue: acpi and kernel.
I have tried to chance several options inside /etc/defaults/
https:/
No success. So, I decided to test if my system could hibernate from console, using /etc/acpi/
The only think that it is working at this moment: adding acpi=off inside menu.lst.
I can not hybernate anymore but system is working after logout.
So, problem seems to be related to kernel+acpi+video.
I can help in debugging if someone say me what to do (files, logs, etc).
