Yet the Microsoft users around me are continually struggling to get basic hardware (SATA controllers, USB3 adapters, USB devices, etc..) working with their machines. Example: android phone/tablets.. driverless for Linux, horridly complex on Windows. But once in a while, yeah, somebody does have to "install a driver" on Linux. And like Microsoft systems, how easy or difficult that is, depends on the hardware vendor supplying the driver. Except on Linux, it doesn't normally include 100MB+ of bloatware along with the driver.

Ok, another try... here's the resullt of the Pi:

Code:

And the result of the Mint box:

Code:

er@desktop ~ $ modprobe usbtouchscreen hid-generic

Again, thanks for all your help Mark!

The touchscreen doesn't appear to show up there on either system, Did you have in a workable state on the RPi when you dumped that info? Oh well. I could probably help a lot more if I had one here to sort out my lack of basic knowledge of the unit. Such a pity that the manufacturer doesn't provide a decent Linux install script for it, or hasn't bothered to get plug-and-play support into the kernel you're running. Weird that the RPi kernel gets it fine though -- Linux is Linux, but perhaps the RPi has some extra patches for stuff like that (which makes sense). Cheers

I must admit: I also find it strange why the "xinput calibrator" works just fine on the RPi, but it doesn't succeed in calibrating the same screen correctly in Mint...When I run it in Mint, the cursor remains in the 4 corners when in tap it in the area of the corner, but is not able to reach the rest of the screen... So I guess this is it: the only option I have left is to cave in and buy a Windows licence. I would have preferred avoiding this, but I guess I have no other choice now. Oh well... Thanks a lot for all your help! _________________________ Riocar 80gig S/N : 010101580 red Riocar 80gig (010102106) - backup
