My new Logitech G5 and changing events (help)
6/9/08 12:27:47 PM

I have recently purchased myself a new Logitech G5 Mouse and attached it to my PC running OpenSuSE 11 (64 bit).
I have everything set up and working, that wasn't very hard.

I followed the directions at http://adterrasperaspera.com/blog/2006/06/20/logitech-g5-review-under-linux (The bit at the bottom, under "How to get it to work in Linux", and "Update:"). This works perfectly. Until I reboot. At this point my problem starts.

After I reboot (or unplug/replug) the mouse, the event handler number changes and the mouse stops working.
Even now it's easy to fix: Change to console, Log in as root, find correct event number, edit xorg.conf, restart X .
I guess it's not so much a problem, more an annoyance.

What I would like to be able to do is either
a) To force a certain event number to be associated with the mouse each and every time the system detects it.
b) Write a script that finds the event number and edits the xorg.conf, either before X loads, or that restarts X after changing xorg.conf.

I'm sure that 'b' would be possible, but I don't know enough about grep, sed, etc... to write the script myself.
I think that 'a' would probably be a better solution though, if it is possible. Maybe through HAL or UDEV?

Can anyone help please?

Have a look in your /dev/input directory. If SuSE has done what many other distributions have done, the appropriate device will be symlinked to some name based on the device's ID.

That's where I'd start looking.
