libgl-switcheroo

FUSE filesystem that pretends to contain $LIB/libGL.so.1 symlinks. On access, redirect to system libGL or primus' libGL based on user's response. User choices are saved in $XDG_CONFIG_HOME/libgl-switcheroo.conf.

Usage

Add the following lines into ~/.xprofile:

mkdir -p /tmp/libgl-switcheroo-$USER/fs
gtkglswitch &
libgl-switcheroo /tmp/libgl-switcheroo-$USER/fs &

If you are using KDM, GDM, or LXDM to login into an X session, the commands from ~/.xprofile are executed. Otherwise, make sure that .xprofile is sourced during X session startup (add . ~/.xprofile into your .xinitrc).

You can then run the following command in a shell session to make all programs run from that session go through the libGL switcheroo (useful for Steam):

export LD_LIBRARY_PATH=/tmp/libgl-switcheroo-$USER/fs/\$LIB${LD_LIBRARY_PATH+:}$LD_LIBRARY_PATH

Building

make LIB64PATH=\"lib\" LIB32PATH=\"lib32\"

Adjust LIBxxPATH variables above as appropriate for your distribution (reflecting how /usr/lib* are named):

• Arch needs lib and lib32 as above
• Gentoo needs lib64 and lib32
• RPM-based may need lib64 and lib
• Debian (with multiarch) needs lib/x86_64-linux-gnu and lib/i386-linux-gnu
• Ubuntu (with multiarch) needs x86_64-linux-gnu and i386-linux-gnu, and additionally LIBPATH=\"/usr/lib\"
