@Rockman98 said in Installing different desktop environment rather than the default one over retropie os?:

Hello,

Is it possible to install a different desktop, specifically Trinity Desktop Environment adn boot over emulation station interface?

Which platform ? On a Raspbery Pi, RetroPie doesn't use a desktop at all.

How can i install it top of retropie os?

RetroPie is not an OS, but runs on top of a Linux distribution - on a Raspberry Pi it's running over RaspiOS, on other platforms is runs over Debian/Ubuntu.

Look up how the desktop environment you want to install is installed on Debian/Ubuntu if you want to install it on your RetroPie - compatible - system.

Would there be any performance issues?

Depends on the system, if it's a Pi3 or less it's probably going to affect the performance, for newer Pi models it's less noticeable and on a PC the difference is basically insignificant.

Can i make it launch like how i start raspberry pi's default desktop environment over retropie os?

Probably, but depends on the platform you're using (PC / Raspberry Pi / etc.).

@logiseye said in System Environment Variable pointing to RetroPie dir?:

@horaceandspider Just tried your tip. Unfortunately e.g. UAE config maker fails, since not only /home/pi is burned in, but also the username pi (e.g. chown pi:pi gets called). And amiberry does seemingly not like symlinks.

@logiseye scripts should be able to use ~/RetroPie. That will point to the RetroPie directory in the home directory of the current user.

All the paths on UAE Config Maker can be changed using the command-line options:

--scandirs
--outputdir
--rom-path

The RetroPie Menu script, you are correct, does use a chown to 'pi' but that can be manually edited, and the script is only provided for less technical users, and is not really the suggested running method.

I will look at switching to ~/RetroPie by default however which seems a clean solution
