Bug Description
Linux Mint Cinnamon 16 64 bit.
The Desktop freezes randomly:
During the freeze it seems, that the desktop is unable to update its contents and process keyboard/mouse input;
The respond to movement, and even change the arrow shape when hovering on different parts of the screen. The applications are still running in the background.
No keyboard combination can affect the display; what works is only the Ctrl+Alt+Fx (and I guess SysRq combinations too, but never tested).
No usefull information can be get from any of the /var/log logs at all... All the logs have no entries at the time of the hanging event.
To reproduce:
1. Install the Linux Mint 16 Cinnamon 64 bit on Asus N56VZ notebook; (https:/
2. Install VirtualBox
3. Run Virual machine. The more machines are simultaneously run, the more probable the freeze is.
Some extra details, just in case:
I use no swap (I still can't get it working with hibernation and encrypted home folder, but that is a different story)
The system uses MBT, / is on BTRFS partition, /boot on smal EXT2 partition, and obligatory FAT32 EFI partition mounted on /boot/efi.
please help...
Correction:
I did more tests and concluded, that the running VirtualBox machine gets damaged during the freeze. I didn't mention, that the VirtualBox machine (Windows XP) was running in seamless mode, so it had a good chance to mess with desktop.
I am doing more tests and I will post more information later.
