Comment 0 for bug 1299821

After closing my laptop lid and allowing it to suspend to RAM, the system would not resume properly.

The visuals on the GUI returned to its previous state without any artifacts, however the mouse pointer was not working. I used a trackpad and a nipple on my T420 laptop. I left it in this state and the mouse was still dead after about 3-4 minutes. After coming back from making a cup of tea the mouse moved but did not interact with any GUI elements.

I have seens some success on previous ubuntu versions if I did a tty switch. This did not work (ctrl+alt+F1), the Unity GUI stayed visible. I then tried the sysreq triggers alt+sysreq RE and lost the mouse pointer again, but the gui stayed visible. I needed to go through the whole alt+sysreq+reisub to make the machine reboot.
