Serial Tablet
« on: March 08, 2013, 05:46:25 PM »
simple question? Has anyone actually gotten a serial tablet working?

Im working on M-275 tablets. with the input-tablet-touchscreen drivers, xorg, and the xorg.conf.d from a working tablet im not getting cursor movement. the device (dev/ttyS1) gives some output in cat with some movements across the screen.

Hi fmayhewubh
Have you looked through   /var/log/Xorg.0.log   for possible clues or errors?

Hi fmayhewubh
If the file is not there then Xorg is probably not running. Does the first line in your  /home/tc/.xsession  file
say Xorg or xvesa?

Hi fmayhewubh
Copy /etc/X11/xorg.conf.vesa to /etc/X11/xorg.conf and make any changes you need to that.
Add the xorg.conf file to your backup. Press Ctrl-Alt-Backspace and then run startx
If Xorg plays nice with your hardware, you'll see your desktop.

Xvesa is still in the .xsession (xvesa -br -screen 1024x786x32... etc) should i change this or will xorg set itself?

Hi fmayhewubh
I don't remember what makes the change in .xsession. Change the first line to:
Code: [Select]
/usr/local/bin/Xorg -nolisten tcp &

Hi fmayhewubh
xorg.conf.vesa is just a sample, Xorg does not look at it. Is Xorg running? Open a terminal and run  top
Is Xorg or xvesa listed?
