** Description changed: Hi, I switch to activated guest session, but the screen remains blank. I have to wake it up with keyboard/mouse action. How to reproduce: 1. login with your account normally. 2. switch to guest session from the panel menu "Switch Account... -> Guest Session", now it's under guest session and the display is normal. 3. switch back to your user account, then switch to guest session again. 4. The screen remains blank. Another method: 1. sudo true && gdbus call --session --dest org.gnome.ScreenSaver \ --object-path /com/canonical/Unity/Session --method \ com.canonical.Unity.Session.ActivateScreenSaver && \ sleep 1 && sudo chvt 1 && sleep 1 && sudo chvt 7 I can't reproduce this issue under Precise. Vivid snapshot 22-Mar-2015 can also reproduce this issue. [Test Case] 1. Run: sudo true && gdbus call --session --dest org.gnome.ScreenSaver \ --object-path /com/canonical/Unity/Session --method \ com.canonical.Unity.Session.ActivateScreenSaver && \ sleep 1 && sudo chvt 1 && sleep 1 && sudo chvt 7 2. Wait few seconds 3. Make sure the screen is black - 4. Move the mouse or type something with the keyboard - 5. Make sure the screen the lockscreen is correctly restored + 4. When restored on tty7, the screen should be not blank anymore [Regression Potential] None - Package: lightdm 1.10.3-0ubuntu2 unity-settings-daemon-14.04.0+14.10.20140606~0ubuntu1 --- ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 CurrentDesktop: Unity DistributionChannelDescriptor: # This is a distribution channel descriptor # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-stella-datong140729-kylin-trusty-amd64-20150205-2DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2015-02-09 (1 days ago) InstallationMedia: Ubuntu 14.04 "Trusty" - Build amd64 LIVE Binary 20150205-07:08 LightdmConfig: [SeatDefaults] autologin-guest=false autologin-user-timeout=0 autologin-session=lightdm-autologin Package: lightdm 1.10.3-0ubuntu2 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 3.13.0-38.65stella1-generic 3.13.11.8 Tags: trusty third-party-packages Uname: Linux 3.13.0-38-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True
