--- Comment #12 from Sandeep sandy.8925@gmail.com --- Note:
Suspend and resume works fine on Windows - the laptop's LVDS display is active and working even after suspend and resume.
I remember that this problem used to occur for Catalyst as well, around version 11.5 , but it got fixed a few months afterwards, and the LVDS display was active after suspend and resume.
I haven't used Catalyst for several months, so cannot comment on whether it still works fine now.
