TFT Touchscreen with eGalax Touch driver + USB Mouse -> weired mouse pointer action
By: c.monty Rank: Starfleet Lieutenant, Junior Grade Postings: 8 From: Germany	Posted: So Aug 23, 2009 - 09:28 hi! i'm running ubuntu 9.04, kernel 2.6.28-15-generic, X server X.Org X Server 1.6.0 Release Date: 2009-2-25 X Protocol Version 11, Revision 0. to get the TFT touchscreen working, i've installed package xserver-xorg-input-evtouch and driver eGalax Touch driver for 32bit Linux kernel 2.6.x, version 2.06.2905-32b-k26. output of cat /proc/bus/input/devices I: Bus=0003 Vendor=0eef Product=0001 Version=0112 N: Name="eGalax Inc. Touch" P: Phys=usb-0000:00:1d.0-2/input0 S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb2/2-2/2-2:1.0/input/input5 U: Uniq= H: Handlers=mouse1 event3 B: EV=1b B: KEY=401 0 30000 0 0 0 0 0 0 0 0 B: ABS=f B: MSC=10 everthing works fine UNTIL i plugin USB mouse controller. then the mouse controller is not working properly, means the pointer is moving on the screen, but i cannot select anything. this problem is described here "Since Xorg 7.2 there is always a default-mouse-pointer which will run simultaneously with evtouch if you do not prevent it from loading. It is extremely important that you add the following to your configuration. Otherwise you will get double click events and all kind of strange things." but as HAL is used i don't know how this should be implemented. can someone assist here? THX

For details, please see the driver guide in the driver package. There also are new Linux drivers available now. Please check http://www.cartft.com/support/drivers/TFT
