Bug Description
The laptop does not suspend on closing the lid, if a DisplayPort monitor is connected. It does suspend normally on closing the lid if no external monitor is connected.
Syslog notes:
Dec 13 21:19:11 down kernel: [ 1627.804109] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment
WORKAROUND: Suspend using method other than lid-closing, e.g. using the System Menu on the desktop.
