Black Screen After Sleep

[Lewis Cowles]

Linux lewis-cd2-xubuntu 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Samsung NP300E5C Laptop
XUbuntu 14.04 64-bit (UEFI enabled with secure boot)
The problem is intermittent (this first occurred when reaching my linux user group, and has only occurred once since upon flapping my laptop down last night, I have however done the same thing on the way back from my LUG and no problem occurred...).
Oh, The system does show the screen to prompt me for my user password but it is after accepting that the screen becomes black, if I flap down the lid and open again then I can again see the user password prompt screen, I enter the password and again black screen, I have also tried leaving the laptop for 15minutes to no avail, it has an intel i3 processor with a 2.8Ghz turbo and 6GB RAM with minimal applications open (Thunderbird, Chrome, Terminal)

Okay I would suggest you have great difficulty reading, my screen does come back on, it merely fails after I enter login details, I have checked that bug and the output of ps -e does not indicate any problem in power management. Also if I switch to another TTY via ALT+F[1-6] I can terminate the graphical session and either terminate X or trigger a soft reboot... I Must say this seems a very lazy response...

Hi thaddus, thanks for taking the time to educate me I am very new to all
this, being that the bug seems to affect XFCE (so not Ubuntu directly) was
something I was worried about, I have now worked out a work-around...

simply CTRL+ALT+F1, login as me, sudo into root, use top to find the
process ID of xfce4-desktop and pkill that process, then the desktop
restarts (no apps though), and I can continue. By no means is this ideal,
but it works for now. Also sadly other than blaming the driver (which I
know it is not as I have since tested this by changing drivers), the "Find
the right package" seems to point to me needing to contact the XFCE
project. Thanks for taking the time to reach out though ;)
