I don't have an Intel video adapter but an Nvidia one and this bug affects me as well. The released fix obviously hasn't solved the bug on my system.

Given that the backtrace for this bug involves routines specific to the intel driver, actually if you're using the -nvidia driver there is zero chance you have this bug.

Hi Nicolo, EXA and server-xorg-video-intel 2.6.3-0ubuntu5 works fine. UXA and server-xorg-video-intel 2.6.3-0ubuntu5 shows not exactly the described bug, if I open a new session, I get directly a black Screen. Previosly I could open a new session and the black screen occurd when switching back to the first session (I'm not shure if this was only with EXA, if necessary I could retest). I'm not shure if this helps, but what works is to open the first session with UXA (then change xorg.conf to EXA) and open the second session with EXA. -- Switching to another user and then to anything else causes freeze in drm_intel_bo_unreference () https://bugs.launchpad.net/bugs/348428 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 348428] Re: Switching to another user and then to anything else causes freeze in drm_intel_bo_unreference ()
The change from 0u1 to 0u2 is the inclusion of these two patches cherrypicked from upstream, to solve bug #344740 which affects i855 chipsets: 114_fix_xv_with_non_gem.patch 115_fix_crash_xv_overlay.patch Both are just tiny one-liners, but as Yoda says, Size matters not! Anyway, I was a touch skeptical at the time that these patches could lead to regressions. Christoph's testing seems to confirm that is indeed the case here. Of the two, 114 seems the most suspicious since it deals with the memory manager. 115 sounds like it corrects a crash situation, so if it is innocent here it would be nice to keep it. I have uploaded a fix which disables 114. Please test and verify this resolves the user switching issue. If not, we can also try reverting 115. -- Switching to another user and then to anything else causes freeze in drm_intel_bo_unreference () https://bugs.launchpad.net/bugs/348428 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

}
*** glibc detected *** /usr/bin/X: double free or corruption (out):

Sounds like a double free. Could 2 sessions cause 2 frees? Or is it
something else. Probably needs additional debug statements to track the
frees. Maybe upstream can provide better insights when they respond.

I am thinking, the second session did not need to allocate a shared resource, and so it did not allocate, but it tries to free it.
