Today when I was visiting a website and wanted to take a screenshot, I pressed Shift+Print Screen. Then I changed my mind and right-clicked the mouse to cancel the screenshot. After I did this, however, the gnome-shell collapsed and there came out a notification asking me to send messages to ubuntu. A moment later the gnome-shell restarted again. So I tried again the operations described above and the same thing happened, except that gnome-shell didn't restart at this time. What was worse, I couldn't input any more! That means I couldn't restart my computer in the terminal. So I used tty2 to restart and reported the problem here, wondering if this is a bug? Or the conflict with other programs? The distribution I use is Ubuntu 12.04.1, and the gnome-shell's version is 3.4.1. Hope my messages do some help. Thank you for reading! _______________________________________________ gnome-list mailing list gnome-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gnome-list
