[Bug 1320554] Re: [Samsung NP350E5C-A02AU] Suspend hang with blank screen on lid open
Christopher, I have changed kernel to 3.15.0-031500rc2-generic.
After reboot, the **wireless mouse was not detected**
I have changed back from xscreensaver to light-locker.
Bug #1303736 suggests that the bug is with the interaction between light-locker and xfce4-power-manager settings.
Lots of Xubuntu users are affected.
I'll continue using this kernel until it something goes wrong but these
issues are starting the affect my ability to work on my machine and soon
I will revert back to Xubuntu 13.04, the last stable Xubuntu.

Title:
[Samsung NP350E5C-A02AU] Suspend hang with blank screen on lid open
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
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.
