Touchscreen HOWTO

[greengeek]

I have a touchscreen enabled Windows tablet (Acer Iconia W501) which uses a 64 bit AMD cpu. I have been trying various 32 and 64 bit puppies with varying degrees of touchscreen success, but would like a recommendation for which puppy would be considered 'standard' enough for testing the concepts in this thread (which I only just stumbled across today...)

Tempestuous - I don't want to waste your time trying non-standard puppies so can you suggest a 'standard' puppy that I could do some meaningful testing with?

(So far I have good reliable behaviour using Slacko 5.3.3t so I know the eGalax usb touchscreen is functional. With 533t the touchscreen is treated like a touchpad - responding to finger direction, and treating a screen tap like a mouse click. It does not provide positional accuracy, so I cannot generate a click at the exact point where my finger touches the screen, but I can position the cursor at the correct position and tap the screen anywhere to click at the cusror position)

I know there are many drivers, and a variety of kernels which treat the drivers differently, so I am not sking for miracles - I just want to work with a 'standard, official' puppy and see where i get to...

Hello @Greengeek. This post assumes one would use their finger on the screen to carry out some needs.

Assuming your smartDevice is x86 64bit Touch technology
I think you may have already tried LightHouse64 on your tablet. If not, you will find some good functionality. Touch an open area on the desktop and navigate the PUP menu system. Open ROX or FM and drag/drop or expand/shrink a window. Taps and double-taps working. All of this desktop touching behaves as if one has a single-button mouse on a system which understands it.

BUT, there is no long-pause and there is not touch mouse-button 2 currently.

Just about everything you can do with a single button mouse was thought of in the build. This included the changing around of mouse activity on an open area of a desktop.

Recently, Slacko64 has resolved a tracking issue with finger and mouse accuracy. But the mouse 1 on desktop has not been addressed yet by any PUP where the tap brings the Menu into visibility for navigation and application launch. This now opens the door for other Puppy advancements in finger-touch control of system activity in the X-Window desktop.

One 3 year-old path in the forest has been paved for us in this OOTB full function PUP distro.

Hope this helps

Hi all.

I try to setup a Master Touch MT500USB screen on Puppy Precise 5.7.1
I installed evtouch-0.8.8 driver, but touchscreen doesn't work correctly.
When I tap screen, cursor moves in little area (approx. 1cm x 1cm), which is scaled from whole screen area.

I did steps from 1st post in this topic.

My xorg.conf

Does anybody could help me to get touchscreen working?

Thanks in advance.
