Obviously I meant ":0.1", not ":1" here.

The "as soon as I touch the touchscreen" statement needs to be corrected.
The error occurs if the :0.1 screen uses a larger resolution than :0.0

I experimented a little more and I found that the touchscreen still reports
coordinates scaled according to the larger screen resolution, in this case
the native 1920x1080 on the external screen.

If I touch the touchscreen outside the 1024x768 area or use a mouse and
move the pointer outside the first screen, then the pointer jumps to :0.1
and appears there at a position just like if :0.0 was overlayed on :0.1.

If I force Screen 1 to have the same or lower resolution than Screen 0,
then obviously the pointer cannot leave Screen 0 and this mouse pointer
bug doesn't occur.

So, yes, "xinput fun".

But in practice, this will be enough since with the POS software we don't
use resolutions higher than 1024x768.

Thanks again for your driver fix!

Zoltán Böszörményi

How to setup independent screens with the Intel driver?

2015-10-30 Thread Boszormenyi Zoltan

Hi,

I am using kernel 4.2.3, Xorg 1.16.4, Mesa 11.0.4 and the current 
xf86-video-intel GIT tip
(commit be3748802398a741208715233d36935378ceff58) on an
OpenEmbedded / Yocto derived distro.

This machine I have to configure and develop for is a POS machine with this 
Intel chip:

# lspci -s 00:02.0
00:02.0 VGA compatible controller: Intel Corporation Atom Processor 
D4xx/D5xx/N4xx/N5xx
Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller])

Without a configuration file, I get clone mode with the two screens.
But I would like to setup two separate screens with :0.0 and :0.1
without Xinerama or unified framebuffer, in order to make fullscreen
X apps cover only one of the screens.

Below is the xorg.conf I am trying to use with the touchscreen configuration 
omitted.

However, Screen 0 gets VGA1 and Screen 1 gets LVDS1+VGA1 according to xrandr:

I tried adding the ZaphodHeads option to the device sections before.
It didn't work. The driver throws an error:

I'm baffled. xinput fun? cursors in the driver are allocated per-CRTC
and handled at a screen level. As far as I am aware, the driver only
has to position a cursor at a certain coordinate on the framebuffer (and
so has to translate that into a CRTC location).

Looks fine to me.

It seems the device pipe and screen matching doesn't work properly.
The driver seems to be assuming that its pipe numbers always match
the same X screen numbers.

In the (semi-)working (mis-)configuration in my original post, LVDS1 is
attached to pipe 0 and VGA1 to pipe 1:

[3110459.475] (--) intel(1): Output LVDS1 using initial mode 1024x768 on pipe 1

and

[3110459.564] (II) intel(0): switch to mode 1024x768@75.0 on VGA1 using pipe 0, 
position
(0, 0), rotation normal, reflection none
[3110459.564] (II) intel(0): Setting screen physical size to 270 x 203
[3110459.591] (II) intel(1): switch to mode 1920x1080@60.0 on VGA1 using pipe 
1, position
(1024, 0), rotation normal, reflection none
[3110459.591] (II) intel(1): Setting screen physical size to 778 x 285

 I tried adding the ZaphodHeads option to the device sections before.
 It didn't work. The driver throws an error:

For the record, switching the screen numbers made the setup work.
Now the problem is that the cursor pointer is on the default screen (:0.0, VGA1)
and the touchscreen obviously controls the pointer on the default screen
and you cannot move the pointer to the secondary screen with the touchscreen.
This won't go with the POS software with further configuration.

Now, how can I convince Xorg to move the core pointer to screen 1?

Assuming? That's how I documented it.

Swap around Screen 0 and Screen 1, i.e. use VGA in Screen 0 and LVDS1 in
Screen 0.

"man intel" on Fedora 22 doesn't says anything like that. Where is it 
documented?

In my case with this particular POS machine, the intended primary display,
the built-in LVDS with a touchscreen attached is apparently wired to pipe 1.

With this driver behaviour, I can't configure it to be kept as the default :0.0 
screen
if an external display is plugged in. Can this behaviour be changed?

Best regards,
Zoltán Böszörményi

Thanks for your work, I just tested it. At startup, it seems to work:
1. it doesn't complain about invalid pipe
2. cursor appears on :0
3. application appears on :0

Then as soon as I touch the touchscreen, the cursor jumps to :1 and
further cursor movements are on :1 from that point.

Attached is my current configuration, hopefully I got it right.

Apparently in my imagination. I could have sworn that I wrote about the
relationship between the Screen number and the CRTC it was assigned and
how you needed to look at the xrandr output to work out possible
arrangements. Probably lost in some bugzilla.

It would need another user parameter. There are several technical
limitations that make automatic assignment difficult. So try

BTW, this is the touchscreen driver in question:
https://github.com/SICOM/xf86-input-eeti-egalax

It doesn't have anything directly screen related, I used xf86-input-void
as the driver skeleton.
