I'm running Intrepid Ibex (gnome) and noticed this issue after reinstalling NetworkManager. After logging into gnome, not able to get anything requiring a window to run. I stopped networking (via networkmanager-applet) and everything is ok. Turn on networking, no programs allowed.
Workaround for me was to stop network, open term, "xhost +", then restart networking. Hope this helps anyone. -- Warning: Unable to open display ':0' and cannot connect to X server :0 https://bugs.launchpad.net/bugs/250712 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
