Anyone know a solution or work around for this?
Ah... Yes, *that* problem. I've seen this as well and the underlying problem is this: (X:0 - first X-server, X:1 - second) * X:0 starts and open the tablet. It also GRABs it to prevent data going to /dev/input/mice (which quite a few X-configurations uses for mouse-input). * You start X:1, but before that happened the VT is switched so X:0 closes the tablet. * X:1 starts and opens/grabs the tablet. * When you switch to X:0 again somehow the close/open/grab cycle fails and that way you will not be able to use the tablet on X:0. I did ask on the linux kernel mailing list about this problem (there are other situations than running two X-servers which are more likely to happend), but I don't think there has been any changes to get the linux kernel 'behave better' in this situation. I have a feeling that the upcoming X-releases will have a better support for hot-plugging input-devices (thus eliminating the mice-device). But until that works and is included in your distro (my guess is that it might take a while) there's not that many options for you. I developed a kernel module to solve some other things I'd wanted and at the same time I (without much thought actually) tweaked the GRAB-behavior to work better in this situation. Feel free to use it if you'd like.
