Hi everyone: I have a xubuntu filesystem of arm s3c6410 and I can enter the system desktop, but s3cXX touchscreen can't work. The filesystem does not have "xorg.conf" and "xorg.conf.d/" in "/etc/X11", then I have created a xorg.conf, As follows： Section "InputDevice" Identifier "My touchscreen" Driver "tslib" Option "CorePointer" Option "Protocol" "Auto" Option "Device" "/dev/input/event0" Option "AllowMouseOpenFail" "true" EndSection Here is log infomation from /var/log/Xorg.0.log: X.Org X Server 1.6.4 Release Date: 2009-9-27 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.28-14-lange51 armv7l Ubuntu Build Date: 26 October 2009 05:21:20PM xorg-server 2:1.6.4-2ubuntu4 (buildd@) Before reporting problems, check <a href="http://wiki.x.org">http://wiki.x.org</a> to make sure that you have the latest version.
