Compix does not work when home is under an encryptfs partition

[Tim Sutton]

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:

{{{

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

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

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.

When you see this problem is Xorg using 100% CPU? This sounds like it may be bug 449437.

[Tim Sutton (timlinux)]

Hi

No its using very little CPU (see below) and doesnt resemble the symptoms from # 449437 at all.

Can someone update this status from incomplete or tell me what other information I can provide to help in finding a resolution to this issue?

Thanks

Tim

It looks like you're running a failsafe GNOME session. Check your session options in gdm before logging in. Compiz will refuse run in a failsafe session since we use that session if compiz is malfunctioning.

[Tim Sutton (timlinux)]

Hi

Erk! That was it - well done & many thanks! Please go ahead and close this ticket.

Regards

Tim

[Travis Watkins (amaranth)]

Alright, thanks for the update. Sorry it took so long to respond and that I didn't spot that the first time.
