Touchscreen on Intermec CV60
« on: November 09, 2012, 02:16:18 PM »
I'll preface this, with I am a bit of a noob.  I am running CorePlus on an Intermec CV60.  Everything is working, and working well, except the touch screen.  I don't think the touchscreen is being recognized, and it certainly isn't working.  When I did a "cat" function on the device events, I could not find an event that was reacting to me touching the screen.

If anyone has some insight (even into where I should start) it would be very helpful and much appreciated!  Thanks!

--I'm going to break this up a bit because the system keeps thinking I'm posting external links....though I'm not.

When I try to list the devices, I can only see a power button, PC speaker, keyboard and mouse, which seem to be handled on events 0-3.

The events shown under the /dev/inputs are event0, event1, event2, event3, mice, mouse0, and ts0.

I have seen another post related to the CV60 that suggested that the 8250_pnp driver may be involved and required.

The 8250 patch bug report says you need to set the serial ports to "always enabled" in bios, when using kernels < 3.1.
The only barriers that can stop you are the ones you create yourself.

Curaga.  Thanks for the reply.  I have them all set to enabled.  The other options were auto and OS managed.  I'm not sure what those mean or whether I should bother trying them.

I have discovered the following:
First, the touchscreen is providing input.  I can see it when I run "cat /dev/ttyS0."
Second, I believe Xvesa will not work due to a limitation of inputs (not 100% sure on that yet).

I'm trying to figure out how to install Xorg, so that I can try evTouch.  Xorg, however, is giving me some difficulty.  I did download a file called Xorg-vesa.lite.core.tcz.  I loaded it with tce-load -i ./Xorg-vesa.lite.core.tcz, and it claimed to load fine.  However, running startx appears to take me back to Xvesa.  I'm new enough that I'm very fuzzy on what needs to be installed and how.

Thanks.

I'm trying to figure out how to install Xorg..

use the apps gui or tce-load to load the Xorg-7.6 extension - hopefully things should work without the need for a configuration file...

Unfortunately, using the tce-load, I have installed Xorg 7.6 and the intel video drivers, and Xorg just gives me a black screen.

In /var/log/Xorg.0.log the system complains about a missing /usr/local/lib/dri/i810_dri.so

According to http://www.x.org/wiki/IntelGraphicsDriver/ the i810 is supported by xf86-video-intel and the package does supply the source for i810 (http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/tree/src/legacy)

The source is placed in "legacy", so it is unclear if the driver is actually supplied or not.

Any help would be appreciated.

(The touch screen does react, incorrectly, to input under Xvesa, if tsharc304c is used.)

which version of tc and which version of Xorg?

You'd have to go back to Xorg-7.5-3d to find /usr/local/lib/X11/modules/dri/i810_dri.so

Hi Juanito
/usr/local/lib/X11/modules/dri/i810_dri.so  is also available in  Xorg-7.4.tcz  and  Xorg-7.6-3d.tcz

All in all, I need to revert to TC 4.4.7 (currently on TC 5.0.2 with Xorg7.7) to get a previous version of Xorg, right?

easy answer: yes, due in part to the significant refactoring of X libraries, libpng, etc, that occurred between tc-4.x and tc-5.x

harder answer: you could attempt to compile the legacy i810_dri.so on tc-5.x

regarding the easy answer: I'm trying to pick this one .. but seem to be unable to grasp the concepts of creating a bootable usb from a freakin' iso .. it's gonna be a long night (apparently it's pretty impossible to make a bootable usb for the CV60, form a Mac .. retrying on an X40 at home ..)

regarding the harder answer: that's how I spend yesterday .. I wouldn't recommend it.
