USB mouse moving slow

Postby ronnil on Sun Sep 02, 2007 3:02 am

Hi everyone

I have installed Cassandra on a dual boot laptop. My touchpad seems to work fine even if i comment it entirely out in /etc/X11/xorg.conf but my USB just won't move allright

I've checked with sudo cat /etc/input/mice and i get results whenever the mouse moves on the screen (like it jumps when i move it)

My mouse is a Kensington ValuOptical Travel mouse, but i also tried with another noname USB mouse with the same result.

I tried setting all sorts of things in xorg.conf and it currently looks like

Code: Select all

Section "InputDevice"
   Identifier   "Configured Mouse"
   Driver      "mouse"
   Option      "CorePointer"
   Option      "Device"      "/dev/input/mice"
   Option      "Protocol"      "ImPS/2"
   Option      "ZAxisMapping"      "4 5"
   Option      "Emulate3Buttons"   "true"
EndSection

Section "InputDevice"
   Identifier   "Synaptics Touchpad"
   Driver      "synaptics"
   Option      "SendCoreEvents"   "true"
   Option      "Device"      "/dev/psaux"
   Option      "Protocol"      "auto-dev"
   Option      "HorizScrollDelta"   "0"
EndSection

...


Section "ServerLayout"
   Identifier   "Default Layout"
   Screen      "Default Screen"
   InputDevice   "Generic Keyboard"
   InputDevice   "Configured Mouse"
   InputDevice     "stylus"   "SendCoreEvents"
   InputDevice     "cursor"   "SendCoreEvents"
   InputDevice     "eraser"   "SendCoreEvents"
   InputDevice   "Synaptics Touchpad"
EndSection


(i left out a lot of stuff for the ease of readability)

I was also reading about setting psmouse_noext=1 in the /boot/grub/menu.lst and tried that, but not sure i did it entirely right.
I also read about some other mouseconfigs to put the same place, about the refresh time for the mouse or something...

would appreciate it alot if i could get it to work, cause it's kinda the only thing stopping me from working entirely in linux (still need iwindows for debugging purposes and netbanking though)

I searched a bit more around, and i think i have to increase my mouse "polling".

found this article for gentoo http://gentoo-wiki.com/TIP_Change_mouse_hz but zcat isn't a part of my library, so i have no idea how to do this on mint.

Any help is more than welcome :) ty in advance

Hi Boo

I got the script working and my touchpad went off (can't find it again with psmouse though, so guess I'll have to reboot...)

However, my mouse is still moving slow :( I'm getting more and more convinced that it has something to do with the refresh rate/polling (heh guess i have learned a new word :P) of the mouse.
Will try searching more for it.

Thanks for the reply though, it's gonna be usefull turning off the touchpad :D

Ok initial problem solved

I got some new info by making that previous touchpadoff.sh thing.

by running lsusb i got the following output

Code: Select all
ronnil@ronnil-laptop:~$ lsusb
Bus 005 Device 001: ID 0000:0000 
Bus 004 Device 001: ID 0000:0000 
Bus 003 Device 001: ID 0000:0000 
Bus 002 Device 003: ID 1267:0201 Logic3 / SpectraVideo plc A4Tech SWOP-3 Mouse
Bus 002 Device 001: ID 0000:0000 
Bus 001 Device 001: ID 0000:0000 


So i googled "Logic3 / SpectraVideo plc A4Tech SWOP-3" finding this post http://ubuntuforums.org/archive/index.php/t-207099.html

so i booted the kernel with irqpoll and voila.... the mouse is moving as it should

Now i just need to work around irq (whatever that is =) )

I'm gonna search the forum and turn back here when further questions arrive. The above was just a little "guide" to other people hopefully finding this post in a google search ;)

I'm the meanwhile I'll just boot with irqpoll
