First,though this is a duplicate question,but i am asking because the other posts didnt help me,and my case is a little different i guess.
This problem is not recent but since 4-5 ubuntu releases...
When i put my system to sleep,it goes to sleep but when wakes up the screen is totally blank. At this moment the real OS is awake as from a diff system,i can do ssh and even tried to play an mp3 file through mplayer and the music played through the speakers.
So the real issue is that the graphics system is not waking up.
I can debug whats wrong and can compare few things before the sleep and after wakeup,but i dont know what tools would help me to see whats wrong with the graphics hardware not waking up.
So please help me debug this problem.
PS: I am on ATI x700 Mobility Radeon Graphics.
