I recently moved from a serial mouse to a PS/2 mouse. So far so good.
The new mouse is a MS optical mouse, which according to my research
should have a resolution of 400 pixels-per-inch. Well, I ran the mouse
along a ruller and I get 18cm for a full 1600pixels which is equivalent
to 222p/i, way below spec.
I did ensure I do not have any acceleation set. In /etc/X11/XF86Config-4
I did NOT set
Option "Resolution"
in
Section "InputDevice"
Anyone has an idea how I can get back the basic full resolution? Does
the X driver have anything to do with it? I run XFree86 4.0.2 with the
nvidia binary driver (1.0.1521, now upgrading to .1541). But I think
X uses a generic mouse driver anyway:
(II) Loading /usr/X11R6/lib/modules/input/mouse_drv.o
Here are the relevant sections (/dev/mouse -> /dev/psaux):
Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/mouse"
EndSection
Section "ServerLayout"
Identifier "Simple Layout"
Screen "Screen 1"
InputDevice "Mouse1" "CorePointer"
InputDevice "Keyboard1" "CoreKeyboard"
EndSection
