Thread: Configure mouse wheel scroll lines

  1. #1

    Default Configure mouse wheel scroll lines

    Hello. I'm installed 64-bit openSUSE 11.4 with GNOME. I have a DELL mouse with middle wheel. How do I configure the lines the wheel scrolls? By default it is about 1-2 lines. I need more.

    I searched many places. Seems only KDE supports this settings. I also digged up VertScrollDelta in xorg.conf, but the latter is not used currently (not exists in /etc/X11/).

    Thanks for help.

    Hi
    If you run the following command, do you see your device?
    Code:
    xinput --list
    Then look at the properties;
    Code:
    xinput --list-props "YOUR DEVICE"
    The files hang out down in /etc/X11/xorg.conf.d now

    Thanks for reply!

    I can list out the device, named "USB Optical Mouse". If I --list-props, the output is

    Code:
    Device 'USB Optical Mouse':
    	Device Enabled (141):	1
    	Coordinate Transformation Matrix (143):	1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
    	Device Accel Profile (260):	0
    	Device Accel Constant Deceleration (261):	1.000000
    	Device Accel Adaptive Deceleration (262):	1.000000
    	Device Accel Velocity Scaling (263):	10.000000
    	Evdev Axis Inversion (264):	0, 0
    	Evdev Axes Swap (266):	0
    	Axis Labels (267):	"Rel X" (151), "Rel Y" (152)
    	Button Labels (268):	"Button Left" (144), "Button Middle" (145), "Button Right" (146), "Button Wheel Up" (147), "Button Wheel Down" (148), "Button Horiz Wheel Left" (149), "Button Horiz Wheel Right" (150)
    	Evdev Middle Button Emulation (269):	0
    	Evdev Middle Button Timeout (270):	50
    	Evdev Wheel Emulation (271):	0
    	Evdev Wheel Emulation Axes (272):	0, 0, 4, 5
    	Evdev Wheel Emulation Inertia (273):	10
    	Evdev Wheel Emulation Timeout (274):	200
    	Evdev Wheel Emulation Button (275):	4
    	Evdev Drag Lock Buttons (276):	0
    However, I cannot find any clue how to find this device under xorg.conf.d. In 11-mouse.conf, there is not an entry with Identifier equals to "USB Optical Mouse". Should I go for 10-evdev.conf or 50-vmmouse.conf?

    I remember I tried to add "VertScrollDelta 99" to all sections in 11-mouse.conf and reboot. Nothing is changed. Therefore I thought openSUSE does not use anything prefixed with "xorg.conf".

    Sorry, I'm very new to openSUSE.

    Hi
    OK, if you try this;
    Code:
    xinput --set-prop --type=int --format=8 ""USB Optical Mouse" "VertScrollDelta" 99

    ... which does not change anything, plus the setting is not retained after reboot. xinput --list-props clearly shows the setting.

    So is this a openSUSE problem or Gnome problem? I heard KDE has such kind of setting.
