Suspend by menu at right upper corner. Waits... Wake up by button. Wallpaper
and logon screen is appeared, periodically I can login and begin work, but not
more than 5 seconds and system completely freezed. I can stay at login screen
without keypress and its freezed too after some seconds.
No mouse, keyboard, led or ssh activity is allowed. Kernel dead.
Using fglrx or fglrx-updates it's no problem with suspend and resume, while
using discrete card (not workaround for me).
I disabled Radeon card (in BIOS) and using i915. All fglrx and fglrx-
updates is completely removed, xorg-radeon too.
kernel option i915.modeset=0 resumed without hangs (but with black
screen), and nomodeset too.
tried to create xorg.conf with uxa

but hangs too :(
Hibernation works without any problem.
Tried latest Linux Mint (booting with usb-stick) - hangs on
suspend/resume too. Sometimes ago can suspend/resume at Windows 7, but I
hate this OS.
I suffered to resolve this problem last three days...
