view story

http://forums.fedoraforum.org – I have FC 17 running. and the touch screen function of the monitor does not work. the HP site says there is no driver. :Y However, % lsusb shows the L2105tm coming in as a QUANTA TouchScreen % grep QUANTA /var/log/Xorg.0.log shows it as /dev/input/mouse1 The other 3button mouse comes in as /dev/input/mouse0 %xinput shows both mice but the touchscreen does not work. % xinput test ... works for the mouse, but no joy with the touchscreen. Any ideas on how to get this to work? Do I need a /etc/udev/rules.d/99thingie.conf file? Do I need a rule in /etc/X11/xconf.d/ (HowTos)
