slumbergod, just to clarify, this bug report is only about your computer
suspending to a black screen. Any other issues regarding mouse
detection, VPN, etc. would need to be handled in a separate report, one
per issue. Hence, when using the latest upstream kernel, was the suspend
to black screen problem reproducible?

** Description changed:

- I'm using a Samsung NP350E5C laptop and I've been having strange issues.
- I gave up on Xubuntu 13.10 and went back to Xubuntu 13.04 until Xubuntu
- 14.04 LTS came out. I'd hoped that the strange issues had been resolved
- but since doing a clean install I have been dogged by weird issues.
- 
- Here's what is causing me grief at the moment. I leave my laptop on 24/7
- and just close the lid when I am away from the machine. I go into the
- system's power settings to disable suspend and hibernation so that
- closing the lid does does nothing. With the kernel that 14.04 shipped
- with it was as though those settings were completely ignored. I'd close
- the lid and when I opened it again, there was a blank screen and I was
- unable to do anything at all, not even start an alternative log in. The
- only option was to hold the power button until the machine ungracefully
- turned off.
- 
- I then applied some hacks I found on line to permanently disable
- hibernation and suspend. I've also installed all the newer kernels as
- they have been offered in synaptic. The problem changed to being
- **intermittent** - my system would randomly hang when I opened the lid.
- 
- With the latest two kernels (including the 27 one that just came out) it
- is now happening **more often**! I'll wake up in the morning, open my
- laptop and there's the blank screen with no way to wake the system up.
- 
- I wonder if there is something strange with Samsung laptops and the
- kernels at the moment. I have to add the acpi_vendor backlight tweak to
- get the brightness working correctly. And for the first  kernel releases
- under 14.04 my usb wireless mouse would not be recognised after a reboot
- -- I'd have to unplug the transmitter then plug it in again.
- 
- I'm still experiencing random system slow downs where my machine slows
- to a crawl. Trying to move the mouse across the screen would take 5 mins
- in little jumps and starts, with no mouse clicks being registered.
- 
- Looking on the forums (http://ubuntuforums.org/showthread.php?t=2224455)
- I see I am not alone and it has been suggested I try a mainline
- lowlatency kernel which as of today I will try.
- 
- I am happy to try any suggestions to help resolve this because this is a
- good machine and it was frustrating having to give up on ubuntu 13.10
- and stay with the older, more dependable versions.
