Description
I can not enable the option that starts Minecraft with Feral GameMode in Prism Launcher running in Firejail, despite adding
whitelist /usr/bin/gamemoderunSteps to Reproduce
Install GameMode (in my case, with
sudo pacman -S gamemode) and install theprismlauncherprofile (into/etc/firejail)Create the file
/etc/firejail/prismlauncher.local(as sudo) and add the following lines to the file (in a text editor as sudo or usingechoas sudo)Run in bash
LC_ALL=C firejail --profile="prismlauncher" /usr/bin/prismlauncherClick on 'Settings' in the top bar
Expected behavior
The 'Enable Feral GameMode' option is not greyed out and you can enable it.
Actual behavior
The 'Enable Feral GameMode' option is greyed out and you can not enable it because 'Feral Interactive's GameMode could not be found on your system'
Behavior without a profile
When running
LC_ALL=C firejail --noprofile /usr/bin/prismlauncher, the behavior is as expected and I am able to enable the 'Enable Feral GameMode' option.Additional context
GameMode is installed on my system. Behavior is as expected when running without Firejail or with
--noprofileEnvironment
