[solved] XDG_CONFIG_HOME to /dev/shm

sk4hrr · 2016-09-06 10:41:24

Hello,

To limit HDD usage, I want to put .cache directory to /dev/shm. On many website, I read the best way is to define XDG_CONFIG_HOME variable in ~/.profile or /etc/profile.

I tested this solution on Lubuntu and works perfectly but on BunsenLabs not.

Here are the lines I added at the end of ~/.profile:

# Optimize
mkdir --mode=755 /dev/shm/sk4hrr
export XDG_CACHE_HOME="/dev/shm/sk4hrr"

After reboot and login, I check if variable is set with the following command :

env | grep XDG

If I type the commands in a terminal, it works.

Thanks for your help :)

edit 15h39:
I just try two things in ~/.profile:
# Optimize
XDG_CACHE_HOME=/dev/shm
and
# Optimize
export XDG_CACHE_HOME=/dev/shm
Same result, I don't understand why my .profile is ignored.

edit 15h47:
This is probably not the best way but this works by editing ~/.xsession and adding commands at the end.

Try adding your command to ~/.xsessionrc instead.

Welcome! And you may have been viewing it from a more Ubuntu-centric login process. Or at least assuming a console based login. I believe that debian's login process of the gui variety, sources your profile from the xsession and .xsessionrc files.

~/.xsession is only run by LightDM if "Default Xsession" is selected as the desktop.

Also, I think Ubuntu handles these things in exactly the same way as Debian.

...and if it exists - which it doesn't in a default BL.

Thanks and sorry, it's ok for now

I don't understand why ~/.profile was edited by developers if it is not used.

.profile is used in non-graphical logins. You can test this by setting some variable there and logging in to another tty and not starting X.

The woes of still trying to remember which login process gives you which profile/xsession/bash config is used..

Actually, .xsessionrc is read in all default X sessions, regardless of DM, but if you startx from a tty .profile will also have been read first.

The movement and flow of which files are called would make for a great full color flowchart diagram...future project idea..
