It seems #1303736 is Not fixed.

Black screen on resume when using standby on close lid is confirmed on
Dell Latitude D400 on completely new install of Xubuntu 14.04.1 32 bit.
downloaded 14 Aug from repository as a .ISO image.

This despite claims to the contrary on the website.

Using the "Suspend" key results in correct operation, i.e. the laptop
suspends and resumes correctly on lid open. Suspending by closing the
laptop lid results in the black screen when re-opening. Once in black
screen mode, the only recourse is power off re-boot.

Although power manager is set correctly to "Suspend" in the power
manager , on closing the lid the system does NOT appear to suspend as it
does when the "Log-off Suspend" button is clicked or the hardware
"Suspend" key is pressed i.e. the problem APPEARS to be on lid close.

Power manager and light-locker set NOT to lock on suspend or shutdown
makes no difference to behaviour.

Xubuntu up to 12.04.4 (plus latest updates) worked absolutely correctly
before new install of 14.04.1

This is a MAJOR inconvenience for an upgrade of an LTS.
