02-21-2008, 01:54 PM #1 jesmith LQ Newbie What's built-in for touchscreens with 2.6.24? I'm working with SLAX 6, which is based on the very latest (7.3) xorg and uses a 2.6.24 kernel (derived from Slackware 12.1). I'm trying to get a touch screen working. The vendor provides closed-source drivers, which need to be recompiled to work with the latest xorg (which he's promised to do for me, but I have no idea how long that will take). I had other problems getting the venerable evtouch_drv driver working. The rub is that my touch screen actually almost works already! It seems that the usbtouchscreen driver in linux and the built-in mouse drivers in X pretty much know what to do. The only problem is that I don't know how to calibrate things. So my mouse cursor doesn't quite reach the left and right edges of the screen, and it goes a a little beyond the top and bottom. It seems odd to me that Linux/Xorg would go this far providing touch screen support, but not take the extra step of giving me some way to calibrate. I'm guessing that instead of using /dev/input/mice, I'd set up separate InputDevice sections in my xorg.conf for the real mouse, and for the touchscreen "mouse", and then I'd give the touchscreen "mouse" some extra options for calibration. But I can't find any documentation on what those options might be. Or perhaps there is some way to push parameters down into the usbtouchscreen driver? Any ideas? -Joshua -- Hardy / touchscreen calibration doesn't work on panasonic t2 (driver evtouch) https://bugs.launchpad.net/bugs/205293 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
