Determine the Mouse to use
xinput --list --short
returns:
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Corsair CORSAIR K70 RGB MK.2 Mechanical Gaming Keyboard Consumer Control id=11 [slave pointer (2)] ⎜ ↳ Corsair CORSAIR K70 RGB MK.2 Mechanical Gaming Keyboard Mouse id=12 [slave pointer (2)] ⎜ ↳ Razer Razer DeathAdder V2 id=8 [slave pointer (2)] ⎜ ↳ Razer Razer DeathAdder V2 Consumer Control id=9 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ Corsair CORSAIR K70 RGB MK.2 Mechanical Gaming Keyboard id=10 [slave keyboard (3)] ↳ Corsair CORSAIR K70 RGB MK.2 Mechanical Gaming Keyboard Consumer Control id=13 [slave keyboard (3)] ↳ Razer Razer DeathAdder V2 Consumer Control id=14 [slave keyboard (3)] ↳ Razer Razer DeathAdder V2 Keyboard id=15 [slave keyboard (3)] ↳ Razer Razer DeathAdder V2 System Control id=16 [slave keyboard (3)] ↳ Razer Razer DeathAdder V2 id=17 [slave keyboard (3)]
NOTE: In this case, the “Razer Razer DeathAdder V2” is the mouse.
- As there are multiple entries, the name “Razer Razer DeathAdder V2” cannot be used as it is not unique.
- Instead, use the id.
- How to know which of the id to use.
Which id to use
In the above results, the Razer DeathAdder is shown multiple times.
- Only the salient id is needed.
xinput | grep -m 1 "DeathAdder"
returns:
⎜ ↳ Razer Razer DeathAdder V2 id=8 [slave pointer (2)]
NOTE: Many mouse show as as both Mouse and Keyboard.
- The Keyboard entries can usually be ignore.
- -m 1 in the grep returns only the first line.
- This shows that id=8 is the relevant line.
- This id may change upon system reboot, so for any future scripts using the id, it is best this is calculated beforehand:
xinput | grep -m 1 "DeathAdder" | sed 's/^.*id=\([0-9]*\)[ \t].*$/\1/'
- returns:
8
Determine Other Device Idenfiers
Device Product Name (Model)
The Product Name (or model):
xinput --list --short
returns:
... Razer Razer DeathAdder V2 ...
NOTE: This is the same as above.
Determine the Device Node
xinput list-props 8 | grep 'Device Node'
returns:
Device Node (279): "/dev/input/event7"
Device Vendor Name (Manufacturer)
The manufacturer or vendor name:
udevadm info --query=property --name=/dev/input/event7 | grep 'VENDOR='
returns:
ID_VENDOR=Razer
NOTE: This is the same as above.
udevadm info --query=all --path=$(udevadm info --query=path --name=$(xinput list-props `xinput | grep -m 1 "DeathAdder" | sed 's/^.*id=\([0-9]*\)[ \t].*$/\1/'` | grep 'Device Node'| awk '{ print $4; }' | sed 's/\"//g')) or udevadm info --query=all --path=$(udevadm info --query=path --name=/dev/input/event7)
returns:

Other way to obtain information
For USB devices:
lsusb -v | grep -e idProduct -e idVendor
NOTE: lsusb uses /var/lib/usbutils/usb.ids to translate ids to names.
For the IDs only:
grep . /sys/bus/usb/devices/*/id*
XOrg Configuration
Putting it all together, a new XOrg configuration InputClass Section would look like:
- /usr/share/X11/xorg.conf.d/60-razer-deathadder-v2.conf
Section "InputClass" Identifier "Razer Deathadder v2" MatchDevicePath "/dev/input/event*" MatchProduct "Razer Razer DeathAdder V2" MatchVendor "Razer" EndSection
NOTE: See Change Mouse Properties.
