Common problems (historical)

These problems have already been fixed. If you still encounter them on the latest firejail version, please report it as a bug.

• Device access on non-systemd systems
• 3D acceleration with nVidia-Hardware

Device access on non-systemd systems

Note: This should be fixed as of firejail 0.9.68 (see RELNOTES, #4725 and #4732).

In order to access devices in /dev on non-systemd systems your user account must be in a supplementary group like audio for example. By default firejail removes all supplementary groups for the most programs. This breaks functions that need devices access like webcams or raw ALSA on such systems.

Add

ignore nogroups
ignore noroot

to your globals.local. If you only need the tty and games group, you can omit ignore noroot.

3D acceleration with nVidia-Hardware

Note: This should be fixed as of firejail 0.9.68 (see RELNOTES, #4725 and #4732).

Users with NVIDIA hardware may need to add ignore nogroups to globals.local, see #3144.
