In some earlier posts, I reported that the screen flickered off. It was sensitive to vibration perhaps.
Pakt reported that it is most likely a faulty HDMI cable.

Yes, that does seem to be the case. Using that cable with my Odroid XU4, when compiling the kernel, the screen started flickering off a lot, I think probably it is a heat issue affecting the cable contacts -- maybe.

Whatever, with my Odroid order I also received a new HDMI cable, and that is working fine. Haven't tried it with the Pi yet.

Perhaps should just throw out the old cable.

GTKhash program launches from the start menu but I can't open a file

Code:
gtkhash  myfile



A gschemas file was missing. Those files are in /usr/share/glib-2.0/schemas. I added DEB 'libgtk-3-common', which has the gtk3 schemas.

Those schemas also need to be compiled, which was not happening in a woofQ cross-build.

Both problems are fixed, thanks for the feedback.

This is just an FYI. A new Raspian OS

Not sure if it will help with compiling behavior.

I purchased Linux-compatible wifi and bluetooth USB adaptors from Amazon, they arrived today.

Tested them on my Pi2, running Quirky 8.0.23 (not uploaded), success.

It's good that RPI3 has both wifi and bluetooth built-in. Can't wait to begin testing...

Update on sound problem...

Here is how I partially solve sound problem on quirky arm...
(the procedure needs to be done each time I boot Rolling Eyes )

When I first boot up I must launch retrovol configuration from tray.

I switch the sides so that left side now has



__________________________________________________


Next I launch retrovol from start menu or tray.

Here is what I see...




I must drag mouse over and set to...



(full is also possible)


Now my volume is excellent and there is no stuttering problem.

I check with
Code:
 madplay  ivy.mp3

_______________________________________


I have just started to look into audio today. Pristine 8.0.23, the audio setup is unchanged from 8.0.18, restarting X server, I don't get the multiple retrovol icons as you reported.
Restarting X, all the X apps get killed, including retrovol, at restart, a new retrovol runs.

I increased the volume to 100%, did a reboot, and it was still at 100%. So, the 10-alsa is remembering the setting, volume anyway.

Running the mixer window, there are two bars, both labeled "PCM", the top one has a ticked checkbox, and that works. Click on the bottom one, crashes retrovol.

I played some short audio files using Pmusic, didn't notice any stutter. Maybe I need to play something longer?

So far have not got sound out of my TV, just using the headphone jack.

Have not yet tried any mods to config.txt.

I think the stuttering is specific to my tv SET. Certain cheaper tv sets aren't
completely compatible to HDMI. But this does happen to others.
There are lots of complaints on the Raspberry pi forum.

I wasn't able to compile gmic plugins
gmic plug-in

but I was able to download someone's rpm package.

gimp-plugin-gmic-1.7.1-3.mga6.armv7hl.rpm

and it worked when I put in a libpng16 link to libpng12.

the 'shared-mime-info' package mis-identifies some text files as binary files. This causes failure of some scripts.

I have posted about this on my blog:

http://barryk.org/news/?viewDetailed=00424

Ubuntu 16.01 has shared-mime-info version 1.5, but I notice the latest is 1.7.

Probably this mis-identification should be reported to the developers, however I just applied the quick fix, rolled back to 0.90.

Another problem with this mis-identification, is that text editors refuse to open the file.

This may cause trouble though, as libpng16 has significant API differences from libpng12.
The libpng developers keep making API changes, which is probably why the Debian (and Ubuntu) developers have stayed with libpng 1.2.x

I'll keep it available for anyone who really needs it.

I noticed that libfftw3 doesn't have header or package content file.
Not that that is very important.
