Desktop icons gone in MATE, caja not started automatically

[Cigydd]

Hello everybody,

I screwed up my system, my fault but I hope someone will help me.

Played around with the GNOME icon themes. I installed the gtk+-3.0-dev package and the librsvg2-dev package in order to compile the basic GNOME icon themes, and that in order to display another icon theme correctly. OK until here.

But this installation filled my 18GiB root partition up completely so I was shocked and decided to remove all the GNOME related stuff I have just installed (provided that the icon theme isn't worth such a mess in the system.

But I accidentally removed gtk+-3.0 binary package itself and I was in a hurry so I didn't read what I'm actually uninstalling.

A big part of the MATE desktop and Mint essentials were gone.

I managed to reinstall everything I hope. Now MATE works as before but I'm missing my desktop icons, it means I'm missing caja being run as the desktop manager. Maybe it crashes on the MATE startup.

When I issue

Code: Select all

pgrep caja

, I get no output. Caja just doesn't run.

As soon as I start caja from the terminal or from the Alt-F2 window, the desktop icons appear.

But if I run caja from the menu, the desktop icons don't appear and I know why: the menu shortcut specifies that caja shouldn't handle the desktop:

Code: Select all

caja --no-desktop --browser %U

So, as a conclusion, there raises a question: how do I start caja on MATE startup to only manage the desktop (without displaying a window with a default location)?
Or, is there a crash happening preventing caja from starting?

I saw a very similar topic to this but it ended up without a clear solution.

Is there a more systematic way than adding

Code: Select all

caja -n

to the Startup Applications list?

If not, I solved this while writing. If yes, I'd like to know that solution.

Solved this by installing the mint-meta-mate package:

Code: Select all

sudo apt-get install mint-meta-mate

All missing packages were installed and caja runs even though I removed it from the Startup Applications list. So should it be.
