Xorg and Tslib

Hello guys!

First of all, congratulations for the great work you have been doing on the Buildroot project!

That's my first message on the group. I have been using Buildroot professionally for some time now.

Nowadays I have a training company here in Brazil, and guess what I am using to teach embedded Linux? Buildroot, of course! :)

OK, so now that I have introduced myself, I would like to talk about about a problem I was having here with X11 and touch screen devices.

I have generated a rootfs with X11 and Matchbox support. Everything but the touchscreen works fine. I could use the ts_calibrate and ts_test tools to test the TS device. But when I started X11/Matchbox, the cursor was not calibrated.

Then I discovered that for X11 to talk directly to TS devices, it needs the xf86-input-tslib driver. And we don't have it on Buildroot (as far as I understood, it was developed by the Ubuntu team, not the xorg team).

I integrated this package to the Buildoot build system, compiled and tested. Everything is working now.

Here is the patch to include the xf86-input-tslib driver:

Pardon a small bit of nit-picking...

Plain text works best for patches.

Thanks for the feedback Michael.

I totally agree that plain text is much better for patches. The problem is that Gmail wraps lines somewhere around 80 characters, as you can see from my first email, and the patch gets all messed up.

I search everywhere in the Gmail configuration and Google forums, and I did not find a way (yet) to disable it.

Anyway, here is the patch again, with the change you suggest:

Hello,

Please don't include "personal" messages before the "---". Everything which is placed before this "---" marker ends up inside the commit message which is stored forever in the Git history.

Moreover, you should add a Signed-off-by: line to your patch. Some further comments below.

Instead of Debian, could you use the upstream version available at
http://www.ptxdist.org/software/xf86-input-tslib/download/ ?

Not needed, this is the default.

Since Buildroot 2011.11, this line should be simply:

$(eval $(call AUTOTARGETS))

The same from me, Merry Christmas and a great 2012 for all of you!

Although I haven't followed buildroot for that long, I have the impression that quite some infrastructure improvements were made this year. Several new download methods were added, including support for development source trees; a cmake infrastructure was created next to gentargets and autotargets; the board support was completely reworked; there have been quite some changes on the toolchain part; linux and the bootloaders now use gentargets as well; and the documentation was converted to asciidoc.

Looking at these achievements, I'm looking forward to seeing the changes in 2012!

All the best,
Thomas

Merry Christmas and Happy New Year from me too!

There were really a lot of improvements in BR this year. I hope next year will bring even more. Let's make it real.
