More evidence, of a rather confusing nature. With default /etc/systemd/logind.conf (which has everything commented out).
With only the laptop display Unity and VT both suspend ok when lid is closed With laptop display + external display Neither Unity nor VT suspend when lid is closed. With HandleLidSwitchDocked=suspend in /etc/systemd/logind.conf With only the laptop display Unity and VT both suspend ok when lid is closed With laptop display + external display Unity does not suspend the first time the lid is closed, but does the second, in fact it suspends every second time the lid is closed (though not absolutely sure this is completely consistent). I think once it was not till the third time that it suspended. VT suspends ok when lid is closed. This is software so there is some sense there somewhere. It is just a matter of finding it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1415958 Title: Laptop + external display does not suspend on lid close Status in unity-settings-daemon package in Ubuntu: New Bug description: Since update to Vivid, laptop does not suspend on lid close if an external monitor is connected, even though suspend is selected in the power settings for lid close. The display flashes and apps move to external display. Syslog shows no attempt to suspend. On Utopic it suspended ok with external monitor. In the logs the lid was closed on Jan 29 15:04:00 and opened at 15:04:30. There are messages in syslog at that time but I suspect they may be a different issue: i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment WORKAROUND: Suspend via the menu. WORKAROUND: Disconnect external monitor first.
