Multiple issues on XU

Post by jolmer »

Hi everyone,

I've got some questions / issues with my XU's in combination with this image:

http://www.odroid.in/Ubuntu_XU/20131030 ... 030.img.xz

My questions:

1) The device won't boot when it's connected to the screen via micro HDMI. Only when I disconnect the screen the device boots.
2) I selected the 'don't ask for a password' option in the user management section, but after every (re)boot the login screens pops up. Is there a way to select a default user, which is used to automatically login?
3) Chromium doesn't support Flash (YouTube). I thought this was build into Chromium?

I hope you can help me with this. Looking forward to get these issues fixed.

~Jolmer

You need ARM pepperflash
http://forum.odroid.com/viewtopic.php?f=8&t=2374
You extract it and with the files moved to the correct place (/usr/lib/PeperFlash) and the config file updated it should work.
Or maybe some one made a ubuntu package to do this ?

1) Its a issue that is almost non-fixable :( Your HDMI screen is sending too much current on the HDMI cable, enough to the XU keeps in a "almost powered" state. So when its connected the Auto-boot feature doesn't work. Because the energy there is enough to keep this part alive. There's a topic on the forums explaining how to add an power button to XU so you can use the power button ..

2) I never did that way.. :( I'll have to test and see what's wrong.. what I do normally is actually edit /etc/lightdm/lightdm.conf and put there

3) Someone will answer, but AFAIK for ARM its not there.. you have to use some "pepperflash" to get it work. Search the forums for pepperflash and you'll probably find the instructions or waiting until someone posts here :)

2) after boot user session can be opened without asking for password
sudo vi /etc/lightdm/lightdm.conf
And then edit the file to look as follows:
[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu
autologin-user=username

Hi everyone,

Thank you for your feedback, I'll look into it.

Mdrjr, I think I have a solution to the issue of not automatically boot on power up when a HDMI cable is attached. I shot a brief and raw video with my cell and post it here:

https://www.youtube.com/watch?v=vw5e33j-zVc

I used a small elco (electrolytic condensator) of 4.7 uF to do the auto power on. The positive pole of the elco is attached to pin #1 and the negative pole to pin #12 of the I/O connector. This briefly shorts those two together, but not continually. That wouldcause the XU to power down after 10 seconds.

I hope this will help others with this issue.

Kind regards

Jolmer

I copied the files to the correct location. Which config file should I edit next, in order to get this working?

This is a very brilliant idea.
Thank you so much.

This worked out fine, thanks for the tip!

How about the installation of PepperFlash? How do I continue?

And one other thing: when I start Chromium in kiosk mode, there's a 1 pixel high gray line at the top of the screen, from side to side. Is there anyone who knows how to fix that?

I found a possible solution myself. I'll give that a try first. Remains the PepperFlash installation. Is it described somewhere already, or can someone help me with a step by step instruction?

Edit /etc/chromium-browser/default so it look like this (or maybe /etc/chromium/default , depends on which distro you are using)

Code: Select all

# Default settings for chromium-browser. This file is sourced by /bin/sh from
# /usr/bin/chromium-browser

# Options to pass to chromium-browser
CHROMIUM_FLAGS=" --ppapi-flash-path=/usr/lib/PepperFlash/libpepflashplayer.so --ppapi-flash-version=11.7.700.225"
Open a tab with chrome:plugins and then disable gnash (if installed) and enable pepperflash

I only get audio, no video. And after I close the browser, the whole screen blanks out for 5 seconds and then it turns on again, very strange.

I use Chromium 28.0.1500.71 on Ubuntu 13.10 (the original image from HK) in Full HD (1920 x 1080).

Any ideas to get this running?

If flash is somehow mulfunctioning with the Chromium browser, you can remove one file as follows:
rm ~/.config/chromium/Local\ State

After that you can invoke Chromium again and flash shall work again.
Thanks to @gripped, he has described that in his/her post. The problem is that one does not
read somebody else's explanations well enough. That was my problem, too.
I didn't read properly at the first time.
If same problems appears again, then one should remove the same file again.
I don't still know, why the file removal helps, and I don't know what tis the relation
of pepperFlash and ordianry flash. Anyway, please read what @gripped was explaining.

Thanks for the explenation, I'll give it a try tomorrow. I didn't read the other thread, since it was explained in this one. Never mind. In all it's pretty much reading, so from time to time I overlook some text.

Thanks, this was the fix!

Is it normal for HD YouTube content to be too heavy to play on the XU, with the setup above (Chromium and PepperFlash)? Can this be optimized in some way?

This will be the starting point?

Has anyone did this before and tested it on the XU and Ubuntu 13.10? Any detailed instruction would be great.

If you find a instruction for U2 or X2 or X2 it will work for you :)

Thanks guys, I'll have a look. But first I'll have to undo the PepperFlash install, right?

I tried it without luck. I get several errors and the video's on YouTube won't play.

So I tried to reverse the previous setup with PepperFlash, but now I get errors there too. The first time I try to open a video, there's an error 'unable to locate or open video' or something like that. After another click on the video it starts playing. Anyone that has a clue on what this might be? I deleted the files in ~/.config/chromium, so that cannot be the problem anymore.
