I installed Ubuntu desktop over Ubuntu server and am facing a serious problem with suspend. When I press any button to resume, the screen flashes white then turns black. Pressing Ctrl+Alt+F1 and other combinations do nothing.
My laptop is the Ubuntu G780. Processor is i7-3570M, GPU is VESA Intel Graphics (Intel HD Graphics 4000). I tried to install the Intel graphics drivers, which has done nothing to fix the problem. I have also used Google to no avail. The backlight problem does not apply to me. Tried the Ubuntu Page with no success.
