Linux Mint 17 32bit virtual machine loads but then crashes with the error message:
"The display server has been shut down about 6 times in the last 90 seconds"
Mint Display Manager (MDM) 1.6.7 issue
The issue is fixed in Linux Mint 17 x32 v2.
To manually fix this issue on older Linux Mint 17 version, update MDM:
sudo apt-get install --reinstall mdm
