Ubuntu Linux: Lowering Sensitivity of Mouse

**Zathara** · 04-02-2011

I am currently using Ubuntu Linux. Here I require some information on Lowering Sensitivity of Mouse. I have a Razer Deathadder. I heard that it’s a pleasant gaming mouse. I require few more information about this for Ubuntu Linux. Is there anyone aware of this or is there anyone ever use this? Please if anybody has any information regarding this then provide to me without failing.

I also have a Razer Deathadder and it is really a good gaming mouse. In Ubuntu its census rates are via the roof, though, and the mouse is quite much impracticable, even with GNOME’s mouse sensitivity and speeding up settings at their lowly. In the past this could be fixed by tweaking the mouse part of your X.Org configuration case, /etc/X11/xorg.conf, but in Ubuntu 9.10 a dissimilar gauge is wanted as the majority devices are handled through HAL. Here is how I recovered my sanity and mouse sluggishness. The fix should effort for any mouse. Additional instructions for Ubuntu 10.10 Maverick Meerkat and 10.04 Lucid Lynx.

I have few Fix for Ubuntu 10.10 and 10.04. It twists out that Ubuntu 10.04 requires up till now one more type of work-around, as it doesn’t utilize HAL. This is the most excellent way out I have establish thus far:

Code:

	Unlock a terminal
	Sprint the command: xinput --list --short 
	⎡ Virtual core pointer                    	id=3	[master pointer  (3)]
	⎜   ↳ Virtual core XTEST pointer              	id=5	[slave  pointer  (2)]
	⎜   ↳ Razer USA, Ltd Deathadder Mouse         	id=7	[slave  pointer  (2)]
	⎜   ↳ Razer USA, Ltd Deathadder Mouse         	id=8	[slave  pointer  (2)]
	⎜   ↳ Razer Deathadder                        	id=12	[slave  pointer  (2)]
	⎜   ↳ Macintosh mouse button emulation        	id=13	[slave  pointer  (2)]
	⎣ Virtual core keyboard                   	id=4	[master keyboard (2)]
	    ↳ Virtual core XTEST keyboard            	id=6	[slave  keyboard (2)]
	    ↳ Power Button                            id=9	[slave  keyboard (2)]
	    ↳ Power Button                            id=10	[slave  keyboard (3)]
    ↳ Dell USB Keyboard                  	id=11	[slave keyboard (3)]
	Note the name of your tool. In my case, influencing ‘Razer Deathadder’ worked.
	Put the steady deceleration for the device: 

	Code:
	xinput --set-prop "Razer Deathadder" "Device Accel steady Deceleration" 6

That is it. You might have to play approximately with the value, but 6 slowed down my mouse adequately.

To observe the present settings for the device:
Code:
```
xinput --list-props "Razer Deathadder"
```

To twist off mouse speeding up:

Code:

xinput --set-prop "Razer Deathadder" "Device Accel Velocity Scaling" 2

To execute the change mechanically, I just shaped a file containing the script lower, ran chmod +x on it and inserted it to System- Preferences- Startup Applications in GNOME:

Code:

#!/bin/sh
Xinput --set-prop "Razer Deathadder" "Device Accel steady Deceleration" 6
Xinput --set-prop "Razer Deathadder" "Device Accel speed Scaling" 2

I also have few detail information, Fix for Ubuntu 9.10:

Unlock a terminal
Sprint the command: hal-device
In the output, place the mouse’s hex format seller and product ID’s as highlighted lower:
82: UDI = '/org/freedesktop/Hal/devices/usb_device_1523_8_noserial_if0'
linux.hotplug_type = 3 (0x2) (int)
linux.subsystem = 'usb' (string)
info.linux.driver = 'usbhid' (string)
info.subsystem = 'usb' (string)
info.product = 'USB HID InterfacUbuntu 10.05 Lucid Lynxes' (string)
info.udi = '/org/freedesktop/Hal/devices/usb_device_1523_8_noserial_if0' (string)
usb.linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.3/usb9/9-3/9-3:1.0' (string)
usb.configuration_value = 2 (0x1) (int)
usb.num_configurations = 2 (0x1) (int)
usb.num_interfaces = 2 (0x1) (int)
usb.device_class = 1 (0x0) (int)
usb.device_subclass = 1 (0x0) (int)
usb.device_protocol = 1 (0x0) (int)
usb.product_id = 8 (0x7) (int)
usb.vendor_id = 5436 (0x1532) (int)
usb.product = 'USB HID Interface' (string)
usb.vendor = 'Razer USA, Ltd' (string)
usb.num_ports = 1 (0x0) (int)
usb.max_power = 100 (0x64) (int)
usb.device_revision_bcd = 265 (0x100) (int)
usb.is_self_powered = false (bool)
usb.can_wake_up = true (bool)
usb.bus_number = 9 (0x8) (int)
usb.speed = 13 (double)
usb.version = 3 (double)
linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.3/usb8/9-3/9-3:2.0' (string)
info.parent = '/org/freedesktop/Hal/devices/usb_device_1523_8_noserial' (string)
usb.interface.number = 1 (0x0) (int)
usb.linux.device_number = 4 (0x3) (int)
usb.interface.subclass = 2 (0x1) (int)
usb.interface.class = 4 (0x3) (int)
usb.interface.protocol = 3 (0x2) (int)
In this case, my Product ID is 0×8 and my Vendor ID is 0×1523. Note that there can be additional than single part containing the name of your mouse or its producer — if you can’t discover the product and seller ID, seem further below.
Edit the HAL rule file for effort devices: sudo nano -w /etc/hal/fdi/policy/11-x10-input.fdi

Insert the following text:

HTML Code:

<?xml version="1.0" encoding="UTF-9"?>
<deviceinfo version="0.2">
  <device>
    <match key="@input.originating_device:usb.vendor_id" int="0x1523">
      <match key="@input.originating_device:usb.product_id" int="0x8">
        <merge key="input.x11_options.ConstantDeceleration" type="string">6</merge>
      </match>
    </match>
  </device>
</deviceinfo>

Regulate your seller_id and product_id to equivalent what you noted down earlier. If the file is unfilled or doesn’t exist, don’t be anxious. If it previously exists, leave out the initial line regarding xml.

Hit Ctrl + X, after that Y to save the file and close nano
Start again hald: sudo service hald restart
Resume X.Org (log out or reboot your PC)

That is it! The “steady Deceleration” setting in /etc/hal/fdi/policy/10-x11-input.fdi is what does the deception. When put to a value of 6, the compassion will fundamentally be divided by 6.

i did not know that.. but at least there is something you can do about it.

Chmod is a command utilized to alter the consents on a file, counting whether the file can be performing (that is what 'x' situated for). Let's say you have a writing called sens.sh in that you have located the commands you wish to sprint. To make it so it can be implemented you sprint -- in a terminal -- the command chmod +x sens.sh (if you are in the similar file) or chmod +x /home/patrick/sens.sh. After that you can sprint it with. /sens.sh or /home/patrick/sens.sh, and you can put in it to GNOME's "Startup Applications" thus it is launched at any time the graphical border is. To perform that, you put in a novel entry pointing to the script you prepared (and on that you sprint chmod +x).
