Okay, I think I know what is causing the problem. My user account is "chris". I created a new user on the system ("sonya") to test with a clean user config, and I could not get the new user account to be choppy on login. Upon examining the config files for user "chris", I noticed that .compiz/session was full of randomly named files, 68 in all. Each one I examined contained basically the same information with the session ID (and corresponding filename) being the only difference:
<?xml version="1.0" encoding="UTF-8"?> <compiz_session id="1011829eca591da96125556878120133800000019200024"> <window id="1011829eca591da96125556878122553100000019200026" title="x-nautilus-desktop" class="Nautilus" name="desktop_window" command="nautilus"> <geometry x="0" y="0" width="1280" height="768"/> </window> </compiz_session> When I deleted all of these files from user "chris", the choppy compiz problems went away. When I copied the session files to user "sonya", the choppy problems began happening with that user. I have attached the 68 session files to this bug report for testing. Simply extract them to your .compiz/session folder. I don't know if this is important, but I am using home encryption. ** Attachment added: "compiz session files for testing" http://launchpadlibrarian.net/33703035/compiz-session-files.tar.gz -- desktop effects occasionally extremely slow https://bugs.launchpad.net/bugs/451382 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
