[i965] [GM965] Kubuntu: after logging out, the KDM login session opens no more

[Katsudon]

Kubuntu 9.10 alpha 3.
Kubuntu + later installed Ubuntu.

After system start, KDM opens correctly the login screen. However, after the logout the screen stays in the text mode with some messages on it and no login screen shows up. One can change screen (Ctrl-Alt-1) and login to the text console.

Could you please attach a copy of /var/log/Xorg.0.log.old and /var/Xorg.0.log after a failed log out and a reboot, along with the output of lspci -vvnn? Thanks.

[Jonathan Thomas (echidnaman)]

Thanks. It appears that the intel video driver is causing Xorg to crash when restarting. I am moving this report on to the intel driver package, and the Ubuntu X people will probably want a full backtrace of the crash: https://wiki.ubuntu.com/X/Backtracing

[Katsudon (katsudon)]

I am afraid I had problems to produce backtrack:

1. apport says "No pending crash reports. ".

2. command
sudo gdb /usr/bin/Xorg /etc/X11/core
results with
/etc/X11/core: No such file or directory.

For other methods from https://wiki.ubuntu.com/X/Backtracing I am probably a bit too lazy. Sorry.

[Jonathan Thomas (echidnaman)]

Ok, we'll see if this is good enough.

A solution/workaround for this bug has been described in the duplicate, bug #404902:
Add

"TerminateServer=true"
in /etc/kde4/kdm/kdmrc in the [X-:*-Core] section.

[Wesley Schwengle (wesleys)]

I have the same issue.

syslog:

/var/log/syslog.1:Aug 23 15:58:18 eniac kdm[3441]: X server for display :0 terminated unexpectedly
/var/log/syslog.1:Aug 23 15:58:18 eniac kdm[3441]: Unable to fire up local display :0; disabling.

Do you need further debug for xserver-xorg-video-intel ?

After system start, KDM opens correctly the login screen. However, after the logout the screen stays in the text mode (tty) and no login screen shows up. One can login to the text console.

Description: Ubuntu 9.10
Release: 9.10
Codename: karmic

This happens after upgrading from 9.04 to 9.10.

The proposed fix does not work:

This bug report has been inactive for quite some time and in the meantime Ubuntu has moved along. I hope the reported problem has been resolved in the current version of Ubuntu. If it has not and there are people willing to follow up with information collecting and testing, it is best to file a new bug report with the latest Ubuntu development version (10.04 still works, but soon 10.10 is better), using the ubuntu-bug command if possible. Feel free to mention the bug number of this bug.

We are sorry that we are not always have the capacity to look at all reported bugs in a timely manner. Occasionally we have to purge old bug reports where no progress has been made, whether it is due to reporter not being able to respond or lack of manpower on the Ubuntu side, in order to keep our list of "active" bugs current. Sorry for the inconvenience this may cause.

Here are a few tips that will make it easier for triagers and developers to process your bug:
* Read https://wiki.ubuntu.com/X/Reporting
* Browse https://wiki.ubuntu.com/X and see if there is some relevant information for you problem
* Respond quickly to questions from triagers
* Try changing things to see if the behaviour changes, e.g.
  * A new mainline kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D (more information at https://wiki.ubuntu.com/KernelTeam/MainlineBuilds)
  * The xorg-edgers PPA: https://launchpad.net/~xorg-edgers/+archive/ppa
  * Various options in `/etc/X11/xorg.conf` (see `man intel`)
* Browse other bug reports to see if you find a similar one and provide the information that is being asked for there.
