Caja starts multible instances after login

Support & Help Requests
#1

Mate 16.04, std paketsources, update, upgrade, dist-upgradeā€¦

I have no idea what the cause isā€¦

After login caja starts multible instances in the taskbar, its full of it (more than 30?.. less than 300?), but the Notebook stays responsible, no crash. Only caja is not usable.

almost the same as here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746339

if I start " caja --sync" in terminal, the cajainstances will shrink till zero, afterwards the caja starts again.
Here is a terminalsession:

I testet system repair, deletet ā€œ.cajaā€, purged and installed caja, switched from compitz to comptonā€¦
nothing helped.

any ideas?

The laptop worked without any problems until maybe 1 or 2 weeks ago, and I really donā€™t remember what iā€™ve done except update, upgrade, dist-upgrade and installed midnight-commander :wink:

Thereā€™s some glitch happening with Antiviral and endless ā€œStarting Cajaā€¦ā€ Have you recently installed that program too?

I think thereā€™s something buggy with how Caja respawns itself, since I can reproduce this too:

killall caja && caja

The correct way to ā€œquitā€ Caja (which only re-opens itself) is this command:

caja -q

Iā€™d suggest checking which extensions are enabled in Caja, and if Midnight Commander has an extension too, itā€™s possible this is causing the problem too.

PS. From your htop output, it seems a bit strange compiz is using a lot of CPU. Is that normal on your system?

synaptic > searched for caja > found installed antiviral-for-caja removed it:

that did the trick! :wink: thanks alot!

htop:
the laptop has nvidia optimus. Because I have no idea whats the best way to deal with it, I use the xorg - nouveau driver until now. Later I will find a better solution with optimus and mate 16.04ā€¦
May be thats the cause withe strange compitz reports in htop?
