Another problem, bug report here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1458327
When using Marco, I can connect to an external monitor, as one would expect. However, using Compiz, both screens go black on connection. So, can have either working suspend, but no external monitor with Compiz, or a working external monitor, but no suspend with Marco :-( -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1454651 Title: Ubuntu Mate with Window Manager Marco fails to properly resume from Suspend on DELL XPS13 Status in linux package in Ubuntu: Confirmed Bug description: I have the DELL XPS13 laptop which came factory pre-installed with Ubuntu 14.04. I changed the desktop to Ubuntu Mate. This had the Window Manager "Marco (Simple desktop effects)" activated. Whenever I went into Suspend, the laptop did resume, but the desktop was not redrawn, no panels, no menus and submenus, no buttons. When I moved the mouse pointer over the places where I assumed the elements to be, some of them did show up, and were clickable. After a reboot, all was normal. WORKAROUND: System > Control Center > MATE Tweak > Windows > Window Manager from Marco to Compiz. --- ApportVersion: 2.14.1-0ubuntu3.10 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: ullix 2099 F.... pulseaudio /dev/snd/controlC0: ullix 2099 F.... pulseaudio CurrentDesktop: MATE DistributionChannelDescriptor: # This is a distribution channel descriptor # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-somerville-trusty-amd64-20140620-0 DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=7b6c248b-36d3-4dcf-9e9e-427d50206af6 InstallationDate: Installed on 2015-04-24 (19 days ago) InstallationMedia: Ubuntu 14.04 "Trusty" - Build amd64 LIVE Binary 20140620-04:25 MachineType: Dell Inc.
