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.

Thanks !

F Edit : here are the files requested /var/log/kern.log

and /var/log/pm-suspend.log

Could you post your /var/log/kern.log and /var/log/pm-suspend.log on and add the links to your question? – Lekensteyn Jul 25 '11 at 14:07
This happens on some HP laptops with certain kernel/driver combinations. What kernel are you using and what is your graphics card? – RolandiXor Aug 27 '11 at 20:13

I used to observe exactly the same problem after I had updated 11.04 ubuntu to 2.6.38-10 kernel's version. The problem resolved when I switched back to 2.6.38-8 version.

Having struggled with this the whole weekend on my HP pavilion dv6, i finally found a solution! Trust me, I have tried every suggestion that can be found on google before this.

What I did was to reinstall windows, update BIOS (download file from HPs support pages), reinstall linux (Linux Mint 14 XFCE). Finally suspend to ram works perfectly!
