Second monitor not used

[Christopher Yeleighton]

I connected two external monitors to my computer HP EliteBook 840: Samsung S2RC450 over HDMI and Samsung SyncMaster 22BW over VGA. The other connection is not visible in Ubuntu (xrandr says "DP2 disconnected").

The monitor connected to the External VGA monitor port recognises the computer.
Ubuntu does not recognise the monitor whereas Microsoft Windows does.

Christopher Yeleighton, any change updating to the Vivid enablement stack as outlined in https://wiki.ubuntu.com/Kernel/LTSEnablementStack ?

[Christopher Yeleighton (giecrilj)]

I can use both displays after updating, thank you!
