Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here.

I am able to reproduce this issue in VirtualBox.

Thanks for taking the time to make Ubuntu better!

Randy Kein - I would suggest filing a new bug report for that. This is restricted to the Natty Xubuntu 64bit images only, probably related to Xfce 4.8. Thanks in advance.

This bug is only present using the "session menu" to reboot and shutdown. If the panel is right-clicked, high-light Panel, then click "Log Out", the system will give you a window with 5 actions. Choose "restart" and the machine restarts as expected. Either method when clicking on "shutdown" will simply logout and leave the user at the GDM screen.

I had the same bug with the logout dialog also... Could someone provide a .xsession-errors from a session that didn't restart/shutdown correctly (if you relogged in after, it will be in .xsession-errors.old instead)? If you can see some errors such as "error 104 (connection reset)", I think Xorg is crashing on shutdown (this bug only appeared with the recent X upload).

Fresh Natty pre-alpha3 installation, instead of running update-manager, went to shutdown. The VBox 64 install went to gdm instead. Checking screens, Alt+F7 is blank, gdm is on Alt+F8. Am attaching the Xsession-errors.txt log file copied while at the gdm screen, before going further.

I have the same problem on one of my computers, which has a Radeon 4650 running the open source radeon drivers. It is intermittent, though, and sometimes doesn't crash. I have yet to see this crash on my other computer, which has a NVidia 460 GTX with the proprietary drivers. (though since I've heard that NVidia replaces part of XOrg with their drivers, I suppose that isn't too surprising that the behavior is different...)

I've disabled the code that causes the crash in bf07cc0, but I think it might be a problem in X itself.
X might still try to use/unref the pixmap set by xfdesktop, but when xfdesktop is closed, this is obviously not available, causing the crash. Not very important to keep the background when xfdesktop is not running any more, but not a proper fix as well.

Yep, noticed that. My terminal windows are not transparent anymore, so i'll wait for a better fix before updating xfdesktop..

partially ... Terminal has back transparency but XChat 2.8.8 has not.

Closing Terminal leaves a zombie process behind, which consumes all CPU time.

It was?? I'm running a freshly-installed copy of Xubuntu 11.04 (with the latest updates, of course), and it's still doing this to me. When I click the Shut Down option, it logs me off instead. I tell my machine to shut down and I go to bed, then come downstairs in the morning to find my computer's been on all night doing nothing, sitting at the login screen.

Xubuntu 11.04 is not running xfdesktop4 4.8.2-1ubutnu1, it is running an older version. Oneiric Ocelot is running the current version and does not have the logoff instead of reboot/shutdown issue. In the status line at the top of the report, the task for natty is still in triaged status, showing this has not been fixed in the release you are using.

there are still no (software rendered) transparent backgrounds in terminal (or rxvt-unicode) on my machine.
