Ubuntu X crashes and shows blank screen with the mouse pointer upon Wake-up

Asked by Rakitha S Beminiwattha

When I tried to wake up my ASUS U46E laptop running Ubuntu 12.04.1 LTS, X crashed and showed blank screen with the mouse pointer after suspend. Only way to recover is to do alt+ctrl+f1 and restart the lightdm by

rakitha$ sudo service lightdm restart

I have a clean installed Ubuntu 12.04.1 LTS and this is the first time I encounter it after the clean install.

system information,
rakitha$ lsb_release -rd

Are there any bugs reported?
Do you have the latest BIOS?

So far I have not submitted this issue as a bug. If you want to I can submit this as a bug. Let me know

About the BIOS version, I checked for updates from Windows before installing the Ubuntu and no new updates were found for the BIOS. My current BIOS release date is,
05/17/2011 and version is U46E.204 (I used the command dmidecode )
also I have never tried to update the BIOS from Ubuntu.
