Hi there,

I had already bought a GuruPlug and a Mimo Touch Screen but was never able to make it work well, so I recently bought a GuiPlug, without buying a screen since I had already one.

At first, everything seem to work, the GuiPlug booted on the screen, but unfortunately, impossible to interact through the touch screen, as if the touch interface was not properly configured.

I decided to reboot the plug, and since then it seems to always boot in "vnc mode". I manage to vnc to the plug and everything is working fine, but I would really need to make the screen work.

Any advice how to proceed? A configuration file I should update/delete?

Many thanks in advance.

Cheers,
Stephane

Stephane,

Try with v2.6

Edit: Nevermind that post, tested on another laptop and the SD card mounts just fine...Back to burning the image to the card now...

Hi James,

Thanks for the quick reply. I downloaded the v2.6 image and extracted it, but I am facing a new problem: I am not able to mount the SD card. I have tried both my laptop's internal SD card reader, and an external USB card reader, but impossible to see the card...
I have checked on the GuiPlug, it is still working fine, but it doesn't show up on my laptop.

How do I copy the image on the card then? I assume I need to use the command 'dd' for that, but I don't know what to put for destination...

Sorry if this is an obvious question.

Cheers,
Stephane

Finally had the time to burn the v2.6 image on the SD card and boot up the GuiPlug.

Unfortunately, it still doesn't work. Exact same behavior.

Plug boots fine, screen comes up fine, things are moving around as they should at boot time, little thingy rotating and all, but once everything is ready, I cannot interact through the touch screen, nothing moves, no way to 'click' the menu or move the cursor...If I don't plug in the monitor, I can VNC to the plug with no problem, so I believe it has something to do with the "touch" part of the touch screen?

Could it be that a config file got created with wrong parameters and is still hanging around and causes the touch interface to not work?
Anything i should check, any log file or config file I could submit to check with you?

Stephane,

Could you  plug the monitor into the booted plug and post a dmesg log please.

Hi James,

Here are the output of dmesg from the GuiPlug. Noob as I am, I cannot make much of it, but it looks like the screen was identified successfully, to a certain point...

Stephane,

Could you post the output from 'ls /dev/input -l'

You should have event 0-2 in that listing so try 'cat /dev/input/event2' then touch the screen, do you see output? (CTRL-C to quit)

Have you tried the monitor on a Desktop PC to confirm that it's not actually a hardware fault?

If you plug in a Usb mouse does the Cursor move normally?

I have only event0 and event1, no event2. Could this be the problem?

I have tested with a usb mouse plugged on the 4 port usb hub, the cursor does move normally.

I have not been able to test on another pc, my ubuntu laptop does not seem to support the monitor, I only get a green screen. But I can confirm it was working with the GuruPlug I had bought previously (with GuiPlug on a usb stick...)

Cheers,
Stephane

[Stephane_Varin]

Anything else I should try? Is this result completely unbelievable? I could have made a mistake in the previous steps...

[Confusticated]

try 'cat /dev/input/event2' then touch the screen

Try James's suggestion with 'event1', the system thinks you have two mice, chances are the second is the touch screen.

If that fails, post the results of

Code: [Select]

grep -C3 'No input driver/identifier' /var/log/Xorg.0.log
and

Code: [Select]

Hi Confusticated,

Unfortunately, cat /dev/input/event1 does nothing (neither does event0)

Looks like the touch screen is indeed identified as a mouse...I suppose it shouldn't ?
