lightdm crashes when running a full screen Webex

[Ayan]

I am running Ubuntu 12.04 LTS on my production machine which is a Dell E 4300 laptop. For emails and Webex, I have a VMware Workstation 9 installed which is running Windows XP professional 32 bit

Often, when I am in full screen in Workstation and have Webex running fullscreen, if I need to click back to my second monitor (Ubuntu Desktop) the screen briefly flickers and lightdm crashes.

Generallu Firefox is the only application that is running on Ubuntu at that moment and all Windows menubars etc dissappears and there is no way to gain access back to the desktop or the applications other than a restart of the machine aby hitting the Alt+Clrt+F1 and logging in and issuing a "reboot" command

A sudo /etc/init.d/lightdm restart does not fix the issue.

This is consistently being hit in 2 out of three Webex sessions

Closing assumed fixed. Sounds like a driver / X issue anyway.
