Some Logitech Gaming Keyboards can work on Linux through Unofficial drivers. There are a few packages available

g15daemonAUR and its dependencies are available in the Arch User Repository (AUR). G15daemon drivers still work for the keyboards they supported, but their development was mostly dropped in 2008, the source is still available for anyone to pick up and continue their development, there are a few bugs in them that were never solved. These drivers use the g15macroAUR to interact with the G keys. There is also a g15statsAUR plugin to show system information on the LCD display.

sidewinderdAUR

hid-lg-g710-plus-dkms-gitAUR

keyledsAUR is available through Arch User Repository. Detailed configuration, effects and LUA scripting are in the project's documentation.

Gnome15 has a list of supported devices on its front page. The keyboards are:

A patch was written to make the G510 keyboard fully compatible with the g15daemon drivers. It is however not compatible with g15macro and as such an alternative approach was needed (which involved heavy modifications of the original code) the result yields much better performance for than using the gnome15 drivers which can currently result in severe input lag for this keyboard.

To apply the patch you must download the g15daemonAUR and libg15AUR sources.

Then download the libg15 and g15daemon patches and modify to your will. The color profiles per M-Led settings are hard coded into the libg15 patch at line 341, 344, 347 and 350 in R,G,B color code.

Then place the files (libg15.patch and g15daemon.patch) into the folders that your packages were downloaded into, after this you must replace the PKGBUILDS with the new ones: g15daemon, libg15 These new PKGBUILDS refer to local sources only, this means they do not fetch sources from the net if they are not present so make sure you hold on to your tar.bz2 files. If you want them to fetch these from the net you can refer to the original PKGBUILDs.

Now install the packages, libg15AUR comes first, libg15renderAUR is required as well before you install g15daemon:

This will compile, install and clean up the extracted sources afterwards to avoid cluttering the folder. I also recommend installing g15statsAUR from AUR next. For fluff.

After the installation you need to create the macro script files, and place them into /usr/share/g15daemon/macros. If you want to create them yourself the files need to be executable and the filenames are corresponding to the label on each key (so for the G1 key use /usr/share/g15daemon/macros/G1). Normally these files should use the bash script syntax.

For commands on the G keys to work with graphical applications g15daemon must be started after the X11 session. To do this you must add these commands to your autostart/xinitrc:

And congratulations! you have a working G510 keyboard on Linux :) With a few issues of course (known issues are in the forum thread linked to at the start of this section)
