I just installed kubuntu 11.04 on my laptop which a hp pavilion dv6, and suspend/hibernate don't seem to work. More specifically, when I try to get out of sleep/hibernation mode, the computer does restart but the screen remains black while the fan starts and the computer gets hot. I have to reboot by pressing on the power button.
I was wondering whether anyone has come up with this problem and might have found a fix for it.
