Mimo 740 Touch Display

[cryporchild]

To use your desktop's keyboard on the plug, try synergy http://synergy2.sourceforge.net/.
It's a really useful program.

Which input driver are you using? If it's "evdev", use xinput to swap the axes like this (once you've got synergy set up):

Code:

xinput set-int-prop 2 "Evdev Axes Swap" 8 1

where 2 is the input device number.

I played with some settings in xorg.conf and finally i got it working correctly

Here is my config:

Code:

Section "Device"
        Identifier      "dl0"
        driver          "displaylink"
        Option  "fbdev" "/dev/fb0"
EndSection

Section "Monitor"
        Identifier "monitor0"
EndSection

Section "Screen"
        Identifier "screen0"
        Device "dl0"
        Monitor "monitor0"
EndSection

Section "InputDevice"
    Identifier "dummy"
    Driver "void"
    Option "Device" "/dev/input/mice"
EndSection

Section "ServerLayout"
        Identifier "Default Layout"
        Screen  "screen0"
        InputDevice "touchscreen" "CorePointer"
InputDevice "dummy"
EndSection

Section "InputDevice"
        Identifier "touchscreen"
        Driver "evtouch"
        Option "Device" "/dev/input/event0"
        Option "DeviceName" "touchscreen"
        Option "MinX" "719"
        Option "MinY" "1057"
        Option "MaxX" "32316"
        Option "MaxY" "31499"
Option "ReportingMode" "Raw"
Option "Emulate3Buttons" "false"
Option "SendCoreEvents" "On"
Option "SwapY" "1"
EndSection

Rabeeh,

Great.  I think the differences were that you are:

1.) Using 2.6.31
2.) Using the  evtouch driver vs. the evdev
3.) Disabling the mouse

I'm not having any issues with interactions between the mouse and the touchscreen...  Maybe because they are both using evdev? 

I would like to try out your calibration utility... wondering if the output will work with the evdev driver... 

Cheers,
Mike

Hi mike,
i've follow your installation steps, but i've used the Rabeeh Khoury's kernel image.
Alla work fine. I'm able to see into my Mimo UM-740 the login shell. But whe i try to run gnome...i see a small graphic blink curson on the left-top of the screen.
I've used your xorg.conf.

Where are my errors?

Hi,

I had the same experience when I first set it up.  I used KDE, and it worked better, so I did not go back to gnome.

OK.
Thanks

[mitsus]

Oh they looks great Love them
It seems that your pictures are brighter
What was the problem finally?

I'm recompiling all system. KDE work great for me too, but with gnome...i'm able to see all using VNC, but nothig on Mimo 740.

Stay tuned.

Regards

[mike]

I'm pretty sure I had the same problem.

Ok now I might need some help.

I have debian-lenny currently running in my guruplug plus 8G sd card. My intention is to have my mimo 720-s running with kde desktop.

Code:

sheevaplug-debian:/# uname -a
Linux sheevaplug-debian 2.6.32-00007-g56678ec #1 PREEMPT Mon Feb 8 03:49:55 PST 2010 armv5tel GNU/Linux

Rabeeh suggested to do the following.
1. Patch kernel 2.6.31 with displaylink support
2. Patch kernel 2.6.31 with ei touch screen support (attached e2itouch.diff)
3. Build kernel with attached .config
4. Use attached xorg.conf that uses evtouch AND disables xorg mouse support (otherwise all sort of artifacts on clicks will happen).
5. Use calibrate application in order to perform the touch screen calibration. Cut and paste the results and place them in your xorg.conf.
Im pretty new to linux so dont wonder if I have some dum questions.

Is suggestion 1. equavalent to download http://www.conan.de/touchscreen/evtouch.html#download xf86-input-evtouch-0.8.8.tar.bz2 and installing it? using the following commands;

Code:

xvjf xf86-input-evtouch-0.8.8.tar.bz2
./configure (in the proper folder)
make
make install

2. I have no idea how to do this.

3. I have no idea how to do this.

4. copy xorg.conf into /etc/X11

5. I'll try calibrate if I get kde running

now if I type startkde through my jtag module it gives this

Code:

sheevaplug-debian:/# startkde
xsetroot:  unable to open display ''
xset:  unable to open display ""
xsetroot:  unable to open display ''
startkde: Starting up...
startkde: Running kpersonalizer...
kwin: cannot connect to X server
kpersonalizer: cannot connect to X server

Step by step instructions are highly appreciated. 

[mitsus]

Try to start X server with:

Code:

# /etc/init.d/kde start or
# startx

...and attach your Xorg log.
