[Qemu-devel] usb tablet working with linux/xfree86 guest in absolute mode

[Jim C. Brown]

The tablet works with the evtouch driver.

To get this to work in a guest:

make sure you have support for usb hid and evdev in the kernel (or as modules).

make sure you have the devices /dev/input/event0 /dev/input/event1 ...
	they might be called /dev/input/evdev0 etc

download the evtouch driver, and install the evtouch_drv.o to
	/usr/X11R6/lib/modules/input

	You can download the driver from
	http://www.stz-softwaretechnik.de/~ke/touchscreen/evtouch.html

Change the default mouse in XF86Config/xorgconfig:

    Section "InputDevice"
        Identifier "Mouse1"
        Driver "evtouch"
	Option "Protocol" "usb"
        Option "Device" "/dev/input/event0"
        Option "DeviceName" "touchscreen"
        Option "SendCoreEvents"
        Option "CorePointer"
        Option "MinX" "0"
        Option "MinY" "0"
        Option "MaxX" "32767"
        Option "MaxY" "32767"
        Option "ReportingMode" "Raw"
    EndSection

    Sample working config is at http://jma-box.student.umd.edu:8080/XF86Config-4

Now restart the X server, and it should work.

Scrolling and the middle button don't seem to be supported by the driver.

Great work!

How about using the old ps2 for that (not disabling it completely, after 
all)?

The following patch (to the evtouch driver) enables both the middle 
button and scroll wheel:

I'll send it to the maintainer of evtouch and see if he'll include it 
for future versions.

Binary driver and sample config available at:

http://jma-box.student.umd.edu:8080/evtouch_drv.o
http://jma-box.student.umd.edu:8080/XF86Config-4

Note that you must have the Option "Emulate3Buttons" "off". Otherwise the
middle button will not work.

Binary driver was compiled with X.org 6.8.2 but it works with XFree86 4.2.1
