AM1808 - Chromium and firefox browsers wouldn't display on the touch screen

Any suggestions? Please.

Never tried that on an AM18xx system. Are you sure you running an X server and it is providing the display?

regards.

Thanks for the replay, Frank!

The board uses Matrix GUI to provide the display. I ran a Hello World, and it displayed fine.

In the Matrix User Guide, is says:

"Any application can be launched by Matrix GUI"

"Matrix GUI uses the graphics display layer. If a launched application also uses the graphics display layer there will be a conflict." (I wonder if it's the case when running Chromium and firefox)

I did look into the X server, and it seemed the board does not have it installed. I'll try to install X server on the board, and see what happens.

Thanks, Prabindh!

Does 'export DISPLAY=0:0' work on Matrix GUI? I had tried this, but it didn't work for me. I wonder if I need to have X server on the board in order for this to work.

Currently, I only have Matrix GUI on the board, and still trying to get X server to work.

Prabindh, thank you so much for this great info!!

I built a rootfs image with Narcissus, and the image works fine on the board. However, the xserver still doesn't seem to work.

Here are the settings that I used to build the rootfs image on Narcissus:

Base setting:

          Select the machine you want to build your rootfs image for: am180x-evm

          Choose your image name: random

          Choose the complexity of the options below: simple

User environment selection:         X11

X11 Desktop Environments:          Xfce 4.6

Additional packages selection:     Firefox

After the system boots, I enter the following two commands:

          $ export DISPLAY=0:0

          $ firefox

I got 'Error: cannot open display: 0:0'

I then enter (to see if the x server is running)

          $ startxfce4

I got

---------------------------------------------------------------------------------------

/usr/bin/startxfce4: X server already running on display 0:0
/etc/xdg/xfce4/xinitrc: line 97: xrdb: not found

(xfce4-session:1840): Gtk-WARNING **: cannot open display: 0:0

---------------------------------------------------------------------------------------

If I enter the following command right after system boots (without 'export DISPLAY=0:0')

          $ startxfce4

I got:

------------------------------------------------------------------------------------

/usr/bin/startxfce4: Starting X server

xinit: unable to run server "X": No such file or directory
Use the -- option, or make sure that /usr/bin is in your path and
that "X" is a program or a link to the right type of server
for your display.  Possible server names include:

    Xorg        Common X server for most displays
    Xvfb        Virtual frame buffer
    Xfake       kdrive-based virtual frame buffer
    Xnest       X server nested in a window on another X server
    Xephyr      kdrive-based nested X server
    Xvnc        X server accessed over VNC's RFB protocol
    Xdmx        Distributed Multi-head X server

xinit: giving up
xinit: unable to connect to X server: No such file or directory
xinit: server error

------------------------------------------------------------------------------------

 Any idea what might be causing all this?

Thank you!

The problem was for some reason Xorg was not included in the rootfs image created by Narcissus (even though I selected X11 as user environment)

I then installed Xorg, but when I try to run 'X - configure', it gave me the following errors.

What could be the problems?

Thank you!

Thanks for everyone's help here!
