I am new to linux. I have just upgraded from 11.04 to 11.10 and now whenever my computer goes to suspend mode I cannot wake it up. I hear the hard drive moving, the screen switches on but it is completely black. I can't do anything except pressing the power button during 5 seconds to shutdown and then restart.
Do you have any idea about what I could do to make it work again, except disabling the suspend mode ?
