I'd like to have a thing cleared.
I just started using Ubuntu and installed 12.04 the only problem is that when i turn my laptop back on after suspension i get a black screen with this written:

legacy_resume():pnp_bus_resume+0x0/0x70 return -19
PM: Device 00:09 failed to resume: error -19
i8042: Can't reactivate AUX port

and after this message at times my touchpad doesn't work as well.
I am currently using a vpc eh2n1e
thanks for the support

pertinent thread (with similar error description but no solution as yet): and also – nutty about natty Feb 13 '13 at 21:34
"Sleep & Resume works fine [from a clean boot]. Following a couple of sleeps, however, the machine gets cranky." Cranky, in my case, means powering-off (physically pulling the plug). This has happened twice already (just now and some time last week). Attempting a tty-rescue would also not work, as the tty-1 session would freeze, too! Very disconcerting! :-( – nutty about natty Feb 13 '13 at 21:41
Do you get past the error message(s) or does your system freeze upon resume (so that you need to physically power-off, as well) ? – nutty about natty Feb 13 '13 at 21:43
In my case this might (unfortunately) be a recent hardware issue, with the following message coming up on boot: 0200: Failure Fixed Disk 1 on my venerable IBM Thinkpad X41 ... :-( – nutty about natty Feb 13 '13 at 22:11

According to this bug it could be due to a bug causing a race condition in libcgroups.

Try this from a terminal:

sudo apt-get install cgroup-lite

sudo apt-get remove cgroup-bin

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – fossfreedom Oct 14 '12 at 9:39
