Did you see this wiki?
OKey. here is my story. I did fresh install 8.10 two days ago and my logitech Dinovo was kinda plug in play. mouse pad was working just fine. all the media buttons as well. to get my Fn7 and Fn8 keys working i followed wiki guide. but it seems to me little confusing. I have few questions for the wiki guide.
Q 1. where should I add the line, options usbhid quirks=0x046d:0xc71f:0x00080000 in my options file ? I mean beginning or end ? What is the command in Kubuntu to edit text file ?
Q.2 My /etc/X11/xorg.conf file does not have any thing that says.....
Option "XkbLayout" "us"
Option "XkbVariant" "basic"
Option "XkbModel" "pc105"
so what am I suppose to do. ?
I modified my /usr/share/X11/xkb/keycodes
put those FK08 ; FK07 numbers and I got my window key working but still no key working to bring main menu. I am lost , Please help me.
by the way, I am editing those files with sudo kate (file path) in terminal. I am not sure is it the proper way ?
