[Bug 466546] [NEW] Compix does not work when home is under an encryptfs partition


Public bug reported:

Binary package hint: compiz

>From the outset I should say I don't know if this is a compiz, encryptfs
or gdm issue. Let me describe the problem.

I have been running karmic (64bit) since about 3 weeks before the
release on my Sony Vaio VGN-NW15G laptop. My home partition is encrypted
using encryptfs (enabled during the setup procedure). Initially compiz
worked fine, but at some stage about 2 weeks before Karmic official
release I noticed that nm-applet and other system tray (battery monitor,
volume control etc) applets failed to launch at log in. If I launch them
manually they work fine. Additionally I noticed that compiz failed to
work any more. My .xession-errors file contained this:

timlinux@timvaio:~$ cat .xsession-errors

Manually starting compiz using the apperances dialog failed too. However
I found that I could get things to behave normally using the following

Press Alt-F2 to get a TTY
Log in as my normal user
sudo stop gdm

Doing this, all the system tray applets would appear as expected on log in, compix works.

It would be great if this could be resolved so that logging in to my
encrypted home gives me a full desktop experience.
