An alternative is just to disable hotplugging from HAL for a specific device. Until the features I needed were ported to the evdev driver, I had to keep using mouse for my trackpoint. By removing the input.x11_driver field, Xorg won't try to hotplug it: $ cat /etc/hal/fdi/policy/no-hotplug-trackpoint.fdi <?xml version="1.0" encoding="ISO-8859-1"?> <deviceinfo version="0.2"> <device> <match key="info.product" contains="TrackPoint"> <remove key="input.x11_driver"/> </match> </device> </deviceinfo> Look at the lshal output to find appropriate fields to match on for your device. > The other option is trying to make the detected driver > use the correct mapping, by suppling some parameters. > > According to the instructions available here > > https://fedoraproject.org/wiki/Features/EvdevInputDriver > > I would have to look at this file: > > /usr/share/hal/fdi/policy/10osvendor/10-tabletPCs.fdi > > However, I did not see anything that I could change > to fix my problem. I'm not really sure how the tablet calibration works. What was the old driver you were trying to use?
