Hi, i'm doing this suggestion because on a laptop running linux with an igpu and dgpu, by default Minecraft is going to be started with the igpu, however I have an nvidia dedicated gpu (rtx 3080) and I would like to be able to use it on Lunar Client, other launchers like Minecraft official launcher allows to be able to set our own java executable per instance, if you need more informations about that please see:

#[Linux] add a DRI_PRIME mode or let users be able to set a custom java executable.
