Sorry I couldn't provide backtrace with debug symbols… Regarding proposed packages: To be sure, I went back to the old versions of packages unity, unity-services and libunity-core-6.0.9 (7.2.5+14.04.20150521.1-0ubuntu1), reboot, crashes are back.
Then I installed the proposed repository, updated the three packages to latest version: 7.2.5+14.04.20150603-0ubuntu1, reboot, no more crashes. ** Tags removed: verification-needed ** Tags added: verification-done -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1451613 Title: [regression] Unity/compiz crashes when locking screen Status in Unity: Invalid Status in Unity 7.2 series: In Progress Status in unity package in Ubuntu: Invalid Status in unity source package in Trusty: Fix Committed Bug description: [ Impact ] A crash is occurring for many users of Trusty when the screen is locking.

The debdiff is found at https://bugs.launchpad.net/unity/+bug/1451613/+attachment/4409311/+files/unity.revert-3810.debdiff ----------------------------------------------------------------------------- Original Description: Since a recent update (around April 29th), sometimes (approximately once a day) when I lock my computer screen (CTRL+L or using system menu) the computer freeze for a while (2 to 30 seconds) before showing the login screen. Then when I try to unlock the screen I need to enter my password twice (with no error message after the first try). Once logged in, all applications are closed. Uptime is still running (since no reboot) and services too (with no interruption). Looking at the apport.log file (see attached) it seems that when I try to lock the screen, compiz crashes. I've attached the compiz crash file too (_usr_bin_compiz.1000.crash) but without the 100Mo data of base64 core dumb… I'm using Ubuntu 14.04 AMD64.
