Ok, I guess I should have been a bit more verbose. I'm fighting with sysfs here, and given that I'm not very familar with it, forgive me my ignorance. Kernel Config I: HID_MULTITOUCH=M USB_HIDDEV=Y TOUCHSCREEN_USB_COMPOSITE=N I do have three mice input devices from udev: mouse0: The Wacom 056a:0090 mouse1: The eGalax 0eef:a001 mouse2: Some attached USB mouse As for mouse1, udevadm points me to input7 in sysfs, and I do get response (with xxd), but no hid_multitouch.ko is loaded (so apparently it is not the reason for existance). Maybe you can extract information from the modalias input: b0003v056Ap0090e0206-e0,1,3,k140,141,14A,14B,14C,ra0,1,18,mlsfw Kernel Config II HID_MULTITOUCH=N USB_HIDDEV=Y TOUCHSCREEN_USB_COMPOSITE=M TOUCHSCREEN_USB_EGALAX=Y Dito. Module not loaded either, but I got the 3 input devices. > > I'm generally wondering why there is not ONE UNIFIED X > > tablet/touchscreen driver for all touchscreens there are.

It all depends on the kernel driver used to > which X driver gets loaded. We'd need that info to go any further. I tried evdev and it does not work (properly), see my mail to xorg-devel for that. And it never will, I think, not for touchscreens (but I'd welcome to be proven wrong). If you need any more infos, shoot, I'll readily trying everything you suggest. PS: There is an opensource KO called "tkusb" provided by the producer of the eGalax for kernels 2.6, but their readme leaves me unclear on whether it is still current, what it requires, and so forth. I also tried their Xorg module (which is said to be for 1.10 and is closed source) and it loads without errors, but shows no response.
