Bug Description

I am used to the fact that sometimes (since at least Ubuntu 10.04) that at least parts of compiz do not work sometimes after reboot or after a while working.

While under Ubuntu 12.04 this works without problems under Ubuntu 12.10 pressing ALT+F2 and entering compiz --replace the restore of the session does not work: Unity launcher is missing, top panel and window borders/decorators also.

See screenshot.

I think that is correct and normal. Try this instead:
    unity --replace

Currently I do not have an Ubuntu 12.10 available (from which I reported this bug) but tried on a test-vm with 12.04 and effect there is that Unity-launcher comes back and top panel, but window decorations still missing.

After applying all the latest updates (machine was not fully up-to-date) they came back after unity --replace but system shows strange behaviour then like flickering windows or starting nautilus twice when clicking on the launcher. Could be related to the vm guest (via virtualbox), so I will try this also on a bare metal installation.

I have tried unity --replace after expierencing high processor usage on a baremetal installation of 12.04 on my laptop.
First attempt did dont bring back the panel elements on the upper right.

On second attempt pressing ALT+F2 and executing unity --replace everything came back but apport came up with a crash report.

I can definitely say, that compiz --replace works fine (better than unity --replace) on Ubuntu 12.04.
So if unity --replace is the one to prefer, it should be fixed.

Hmm, actually I should have tested it sooner. Running compiz --replace on 12.10 fails because of bug 1085591. Marking this as a duplicate of that until proven otherwise.
