The leak is around 200 bytes (one XEvent) per frame or about 12.5KB per second. It is most noticeable if some application is continuously redrawing during this time. But only if the application itself does not sync to vblank. For example: KVM, QEMU or: env vblank_mode=0 glxgears WORKAROUNDS: 1. Before leaving/locking the PC run ccsm, and in the OpenGL section disable "Sync To VBlank". 2. Before leaving/locking the PC, minimize all active windows. 3. Install fglrx driver from AMD/ATI. But then you'll have bug 969860. ORIGINAL DESCRIPTION: There are two issues. Compiz has a memory leak so it expands to take up all memory plus swap (12 + 4 gig) Unity shows a blank screen and does not come up with a login prompt, only the mouse pointer is displayed. ctl+alt F1 works so you can get into a console and create the attached bug report. This was after killing vviewer and before restarting lightdm I was running KVM and vviewer as well and killed vviewer but still did not get get login screen Killed compiz which freed the memory still did not get login screen had to restart lightdm to get back into Unity and restart everything.
