Hi *
I installed Ubuntu 12.04 on my MacBook Pro 8, 1 when it was released. It has been working well overall, but I have a problem when it comes to suspend and resume operations.
When instructed to (by the closing of the lid etc.), the laptop suspends most of the time.
Ever since the update kernel 3.4 my laptop runs slow until after a suspend/resume.It seems something has gone wrong with the power management settings from powerup, that then get corrected through the suspend/resume cycle.Its now getting rather anoying having to suspend my machine after boot, just to be able to use it.Does any know what the problem might be or what information I should look at to
This is not 100% reproducible, but occurs at least half the time.
I am using Fedora 18 on my laptop (HP EliteBook 2540p) with the MATE window manager. After installing lightdm to replace gdm, I can set my laptop to suspend when the lid is closed. However, when I resume by opening it and pressing the power button, it often wakes only briefly (a few seconds) and then suspends again.
I'll copy the post of "ethanay" from the m1330 thread that seems to be unanswered...
I'm having the same problem:

Suspend works for me mostly, but when I close the lid and leave it suspended for a while, then resume, it automatically suspends a 2nd time.
Hi world
I need your help.
My Dell latitude D800 shows black screen on Resume/Thaw.
Hi,
I am running Fedora 17 on a Fujitsu Siemens Amilo li1718 laptop with Radeon Xpress 200m graphics card. When trying to resume after suspend I just get a blank screen. Also the wireless light goes out. No buttons work. I have to hold the power button to force the computer to turn off, then reboot.
Hello everyone, it seem like a good idea to leave the computer along when it is updating. Because if for some reason I still using the computer, it might interrupt the updating process.(e.g. update manager freeze, or corrupt some file) I remember I run into this problem quite a few times back in FC6, but did not have problem on F10 and F11(merging from preview?) until the day before yesterday.
After a kernel update from 3.3.7-1 to 3.4.0-1, my AMD64 F17 desktop system will no longer resume from suspend. The keyboard has no effect. When I hit the power button, I can hear the disk spin up, but the system is still unresponsive. /var/log/pm-suspend.log shows a normal suspend, but nothing else ( a successful resume will start with an "Awake" entry after the last suspend entry).
Getting a screen full of white and black pixels when trying to resume operation on a laptop.
Suspend operation in one of two ways:
1) simply close the cover
2) select "suspend" from the menu
By resuming, I mean to try to turn on the laptop again.
I get a bunch of "failed" messages re. channel 1, channel 2, etc.
