           Summary: X freezes when changing of X session (or DISPLAY)
           Product: xorg
           Version: 6.8.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: lsom at free.fr


I am using 2 user accounts simultaneously : one to work and one to go on the
web, etc.
I am switching from one session to the other using the keys ctrl-alt-F7 /
ctrl-alt-F8.

On versions 6.8.1 and 6.8.2 X freezes when beginning to display the new session
: no more keyboard (numlock doesn't work), sometimes ctrl-alt-del enables to
reboot "cleanly". ctrl-alt-backspace to kill X does not work.

This is typically a bug on the driver : I had the problem with XFree with the
first versions of the driver.

I have a Radeon 9200SE

* Slackware 10.0 - Xorg 6.7 (Release Date: 18 December 2003 - X Protocol Version
11, Revision 0)
 !! OK !!

* Slackware 10.1 - Xorg 6.8.1 : PROBLEM
* Slackware 10.1 - Xorg 6.8.2 (binary package) : PROBLEM
* Slackware 10.1 - Xorg 6.8.2 (compiled with the Slackbuild) : PROBLEM
Back to 6.7:
* Slackware 10.1 - Xorg 6.7 (binary package of Slack 10.0) : !! OK !!

There is a bug on the 2 last versions of Xorg but I had no better perfs (on
single display, with glxgears) than with the 6.7 version...

Thanks
