Hi, I encountered the same problem since 2-3 weeks now.
My setup : - Ubuntu 14.04 LTS - Lenovo ThinkPad T420 + an additional Lenovo Screen ThinkVision (20") + Logitech Anywhere MX mouse I use the shortcut "Windows + L" (same as CTRL+ALT+L but less fingers are needed) to lock my laptop. I cannot reproduce the issue, but it happens every day. I have the same crash with Compiz (_usr_bin_compiz.1000.crash) I tried to update Unity package, but the crash hasn't been fixed. unity 7.2.5 + 14.04.20150 amd64 compiz 1:0.9.11.3 + 14.04. all -- 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: Unity/compiz crashes when locking screen Status in Unity: Confirmed Status in unity package in Ubuntu: Confirmed Bug 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.
