Is it possible?

I mean keeping current user enviroment (starting from another user isn't appropriate at my case).

KDE applications will follow the configuration settings as set in the user configuration directory, which is usually ~/.kde or ~/.kde4 and can be changed at runtime with the $KDEHOME environment variable.

I must keep current environment, KDE's one also.

Can you please clarify what you are trying to do?

I try to find a workaround of this famous (I mean highly voted) and longstanding bug:

https://bugs.kde.org/show_bug.cgi?id=229452

So you wish to start Amarok with a different colour scheme to the rest of KDE?
You can do this by having a different set of settings for it.

Open Konsole, and enter "export KDEHOME=$HOME/.kde4-amarok/"
Then run "systemsettings" and configure how you would like Amarok to appear ( colour scheme, etc. )
Finally, run "amarok" to start Amarok itself.

Note that you will need to run the first command ( export... ) in Konsole each time you wish to start Amarok. ( And Amarok must be started from that same console )

Ugh... At least an hour for all settings is needed

Thanks! I'll try (well, of course I'll try to use bash script for amarok starting, when the settings be done).

New config dir contains links to 'cache', 'socket' and 'tmp' inside /tmp. This way main KDE environment intersects with amarok's one. Is it safe?

As long as there is no significant difference in settings, it should be fine.

Thanks!

So there are no environment variables which allow overriding color or UI schemes? I think GTK allows such kind of thing with GTK_PATH variable, which can be useful in some cases to point to a custom theme. I just run into a problem with running Meld with Krita Dark color scheme (using oxygen GTK theme set for GTK applications). Meld looks really unreadable in that case...

You can change the style engine which is used, but from what I am aware Krita forces this to Oxygen anyway.
Unfortunately I am not aware of any environment variable or command line argument you can pass to an application which would change it's behaviour in regards to using a different colour scheme. The only thing you can do is set an alternative KDEHOME and have a completely different set of settings for that application.

This is an old post, but I am trying to do something similar with plasma 5, but it seems like changing KDEHOME doesn't work. Do you maybe have a clue why?

I'm trying to do this in Plasma 5 too.

I would like to set a couple of apps to run with the normal Breeze theme while having Breeze Dark as my default.

With the KDE Frameworks 5:

Thanks!

I made an alternative .config directory and now I can use

Code: Select all

export XDG_CONFIG_HOME = /home/user/.config_alt ; program

I made the alternative config directory by changing the theme to the alternative theme and saving the .config directory in another directory, called .config_alt.

EDIT: Still does not work for libreoffice.
