Ticket #11995 (new defect)
Saving Ubuntu guest in full-screen mode causes guest X session hang when resuming. Windows 8 host.
|Reported by:||jimav||Owned by:|
Host is Windows 8 64-bit, guest is Ubuntu 13.04 64 bit.
Everything works fine including saving state & restoring when the guest is in a normal window. But if the guest is saved while in full-screen mode, then when the guest is restored it is unresponsive, cursors do not flash, etc.
However the "hung" guest does respond to Host-F1 and switches to a VT where you can log and kill the X server, after which normal operation resumes.
So saving or restoring in full-screen-mode breaks something related to sending events to the guest X server.
HOW TO REPRODUCE:
Start Ubuntu guest Go to full screen (Host-F) Put cursor at bottom of screen to get vbox menu, then Machine->Close-Save Machine State
Restart the saved VM. It hangs.
(to recover: Host-F1, log in as root and kill the X server process)
I'll attach two log files (one from the session which ended with a save while in full-screen mode), the other from the restarted VM with the hung X server.
