I was running into problems getting the Top/Bottom X/Y attributes to work in an xorg.conf.d file when I stumbled across the following thread: http://old.nabble.com/Wacom-drivers-ignore-BottomX-td31169628.html
I was trying to figure out what was going wrong (since I saw no obvious problems with the referenced commits) when I stumbled across a weird hotplugging issue. It seems that on my system, hotplugging a tablet will cause other attached tablets to reset some of their properties back to the default. My system (Arch Linux; kernel 2.6.39.1-1; xorg-server 1.10.2-1) and Ping's install of Fedora 15 both exhibit the behavior, though I was unable to reproduce it on a VM of Ubuntu 11.04. I've tested with the latest git as well as 0.11.0 and the issue was present in both. Properties that are being reset include: * Area * PressureCurve * Mode * TabletPCButton * Touch * Rotate Testing procedure: 1. Have at least one tablet plugged in 2. `xsetwacom set $FIRST_TABLET_STYLUS area 1 2 3 4` 3. `xsetwacom get $FIRST_TABLET_STYLUS area` 4. Plug in another tablet (unplugging and replugging a 2nd tablet works as well) 5. `xsetwacom get $FIRST_TABLET_STYLUS area` 6. See if the output from step 3 and 5 are different I did a little poking around in GDB to see if I could figure out what's going on, but I'm missing the server's debug symbols at the moment. What little I can tell though is that wcmSetProperty is being called by XIChangeDeviceProperty for several (all?) tablets after the newly-hotplugged tablet is completely initialized. Tying back in with the original issue, this causes the Top/Bottom X/Y settings to be immediately reset to their defaults... Anyway, I won't be able to do much poking around on this over the weekend, but I figured I'd let the list know in case somebody else is interested.
