guest session, switch user, fail, "cannot start new display"

[nanotube]

Binary package hint: xorg

Using intrepid 32bit, with latest updates.

When I try to switch user, or start a guest session, screen locks, but nothing else happens, and I am just stuck at the locked screen. I unlock it and see a "cannot start new display" error.

I tried running gdmflexiserver with -d option to see what happens... but that's not too helpful:

gdmflexiserver[998]: DEBUG: Sending command: 'VERSION'
gdmflexiserver[998]: DEBUG: Got response: 'GDM 2.20.8'
gdmflexiserver[998]: DEBUG: Sending command: 'AUTH_LOCAL e8d364c4fa93aea39a02c39a53983c61'
gdmflexiserver[998]: DEBUG: Got response: 'OK'

gdmflexiserver[998]: DEBUG: Got response: 'OK'
gdmflexiserver[998]: DEBUG: Sending command: 'FLEXI_XSERVER_USER :guest'

didn't see anything that looked suspicious in xorg.0.log either, but maybe i didn't look well :)

Please let me know if there's any other info I can enclose that may be helpful...

Thank you for your bug report. It is not obvious from the information you've provided why the second session fails to start. Could you please try switching user, and then attaching your /var/log/Xorg.20.log and /var/log/Xorg.20.log.old files if you have them?

Thanks

Hi,
Aha, yes, these files do exist (I have tried switching user several times). Here they come.

Same problem here. I have a different last messages in my Xorg.2[01].log files:

(II) Open ACPI successful (/var/run/acpid.socket)
(II) Loader magic: 0x81d9a40
(II) Module ABI versions:
        X.Org ANSI C Emulation: 0.4
        X.Org Video Driver: 4.1
        X.Org XInput driver : 2.1

        X.Org Font Renderer : 0.6
(II) Loader running on linux

Fatal server error:

Should be fixed now. This was being caused by an Xv patch for another bug, which now is solved a different way.

Hi Bryce
Thanks for the update.
Will this fix be released for intrepid?
