#touchscreen
I've been looking at improving the usefulness of my separate #touchscreen when using a #program like #xournalpp for making sketches and writing on a display for other to see. It works OK with #X11 but the response to touches of the #stylus on the screen is a bit frustrating. However, with #Wayland, it seems to be so much better, which means the #hardware is fine and it's the #software that is not very sensitive.
The only issue I have now is that I can only get it work as a clone of the laptop display and not as a separate screen. This works with X11 though I have to adjust things a bit with #xinput. But in Wayland, touches on the screen as configured "to the right" of the main display map back to the #mouse #cursor on the main screen and not on the touchscreen itself. Does anyone have any ideas about a possible solution?
Today I had to give two different presentations in two entirely different places, neither of which had an #HDMI connection, which is the only #video output I have on my #laptop. Both still had #VGA, which is pretty ancient these days. Luckily, a few years ago, I bought an HMDI-to-VGA #adaptor but initially I had difficulty with using it, perhaps because of lack of full support in #KDE. Colours were sometimes different or flashed or gave some odd artefacts on the projected image. Happily, now things have been sorted out and everything worked really well. I was also using an extra #touchscreen and an #HDMI duplicator to send the signal to two outputs at once. Thanks to all the #FreeSoftware hackers who made this possible.

“Stomach Shot” Halloween Costume
Wed, 12 Nov 2014 06:00:48 +0000, by Josh Marsh
Halloween may have come and gone, but [Luis] sent us this build that you'll
want to check out. An avid _Walking Dead _fan, he put in some serious effort
to an otherwise simple bloody t-shirt and created this see-through "stomach
shot" gunshot wound.
The project uses a Raspi running the Pi
Camera script to
feed video from a webcam on the back of his costume to a 7″ screen on the
front. [Luis] attached the screen to a GoPro chest harness—they look a bit
like suspenders—to keep it centered, then built up a layer of latex around the
display to … Read more
