Viktor Pal, I'm using both gnome-session-flashback + Metacity in Vivid and Wily, and I've not been able to reproduce this.
Despite this, to advise, the scope of this report is precisely: " The program 'metacity' received an X Window System error." Hence, reviewing another report you previously filed isn't going to be terribly helpful here. Also, if you are going to use gnome-shell going forward, or want to report an xorg related crash while using it, it will be helpful to file it in a new report, versus mention it here. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1455916 Title: [Dell Inspiron N5110] Xorg unexpectedly crashed Status in xorg package in Ubuntu: Incomplete Bug description: Xorg unexpectedly crashed bringing down down metacity and gnome-flashback too.
