I do have the same problem but this happens only on some computer (HP for instance). This is caused by the gnome settings daemon that crashes when the user logs in :
kernel: [ 63.358948] gnome-settings-[2697]: segfault at 8 ip b5bc514c sp bfa389d0 error 4 in libpower.so[b5bb5000+18000] Removing the library that crashes gnome-settings is a workaround (in my case /usr/lib/gnome-settings-daemon-3.0/libpower.so). I'm not sure if it's related to bug 971353. I also noticed that the original admin account on the workstation don't experience the crash. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/995372 Title: switching external monitors impossible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/995372/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
