Razer Imperator

[HTS]

Hey guys,

Just got a Razer Imperator gaming mouse and thought I would share some settings which worked well for me.
I booted windows and installed the Razer configuration utility to set the DPI to 5600 DPI and polling rate to 1000Hz for games (I don't use the top buttons to switch DPI profiles as I use those for gaming macros).

Booting Linux with those settings obviously makes the mouse pointer SUPER fast.

The best way to fix this is to use xinput to find the right values.
use:
xinput list
to find the device

Note: if you get 2 Razer mice in the list, try setting the pointer speed on each in turn to find out which one is the correct device.

and:
xinput list-props [device]
to discover the supported properties.

I hate pointer acceleration so I basically only played with ConstantDeceleration.
Once you found the right values store them in /etc/X11/xorg.conf.d/10-mouse.conf.

Here is my mouse section for reference.

Code: Select all

Section "InputClass"
   Identifier "mouse" 
   MatchIsPointer "on"
   MatchDevicePath "/dev/input/event*"
   Driver "evdev" 
   Option "AutoServerLayout" "on" 
   Option "AccelerationProfile" "-1" 
   Option "ConstantDeceleration" "5.0" 
   Option "VelocityScale" "1.0" 
EndSection

The "Match" part could be improved to only match the Razer mouse if using multiple mice.

Enjoy your super smooth mouse in Gentoo!

Edit: updated for newer Xorg

Hi HTS, this works nicely for my Imperator too.

You wouldn't have a Razer Keyboard lying around, would you?
I have a Razer Reclusa and am having some sort of conflicting situation with the very Imperator mouse. It's driving me mad...

But anyway nice config.

Moved from Desktop Environments to Documentation, Tips & Tricks as it fits better here.

Thanks tomk.
Sorry popsUlfr I do not have the keyboard yet but might well get it at some point as I'm running out of macro buttons

Thanks alot mate!

I think it doesn't work with the Gnome 3 preferences is because the Razer mouse is listed twice by xinput --list.

Code: Select all

xinput --list
Virtual core pointer                    	id=2	[master pointer  (3)]
   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
   ↳ HID 046a:0023                           	id=10	[slave  pointer  (2)]
   ↳ Razer Razer Imperator                   	id=11	[slave  pointer  (2)]
   ↳ Razer Razer Imperator                   	id=12	[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)]
    ↳ Video Bus                               	id=7	[slave  keyboard (3)]
    ↳ Power Button                            	id=8	[slave  keyboard (3)]
    ↳ HID 046a:0023                           	id=9	[slave  keyboard (3)]

Thanks for this nice config HTS.

It came in handy when I had to add
Option "AutoAddDevices" "OFF"
to my xorg for my keyboard to work flawlessly.

Somehow the combination of both configs is not working perfectly as I lost the back/forward functionality of the mouse's buttons in browsers.
Do these still work for you or did you find another trick to make them work?

Hey jupiter,

I remapped the back/forward buttons to gaming macros so can't easily test this right now. If I can backup the mouse config I'll try it.
