I have the same exact issue. I can run startx from the cli and then launch Unity from a terminal -- as soon as Unity tries to launch, it kicks me back out with the same error message you guys are seeing: https://launchpadlibrarian.net/113232426/IMG_0855.JPG
I started a bug report here as well: #1039148. Let's hope that this gets resolved soon. Very frustrating and unproductive. I noticed that, besides Firefox and Thunderbird, crashing, the Online Accounts app from within System Settings kicks me out of the session back to lightdm. So what's the thought here? Are we looking at an NVIDIA, Xorg or Unity or Compiz issue here? What else can I do to provide debugging info? Thanks. ** Tags added: compiz nvidia-current unity -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1037173 Title: Xorg crashed with SIGABRT in FreeResource() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1037173/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
