Quirky Xerus 8.1.4 for Raspberry Pi2 and 3

[dancytron]

That seems to be the normal "make Chromium run as root" problem.

Try

Code: Select all

/usr/bin/chromium-browser  --no-sandbox

or

Code: Select all

/usr/bin/chromium-browser --user-data-dir=/root/chrome/user --disk-cache-dir=/root/chrome/cache  --no-sandbox

You can put that in a script or edit the chromium wrapper script for convenience if it works.

PM Mike Walsh if that doesn't work, he's the Chrome guy.

I took a look at 'raspi-config' in Raspbian. It is a text-mode utility to set various things. A bit like QuickSetup in Quirky, kind of.

The feature I like best about raspi-config --->
it allows user to set up ssh if desired

and I tried

I will do as you suggest and send a PM to Mike Walsh. Thanks again.

I was able to compile the latest
imagemagick 7.0.3

It's a big package. It could be reduced I'm sure if I knew more about the app.

Hi dancytron,

Thank you for those links on Chromium browser crashing, very interesting and informative.

For those who have not read the links, the problem seems to affect the armhf version of Chromium rather than any specific device. The problem has been described on Raspberry Pi 2 and 3, also on the odroid XU3. It has been described with Ubuntu Mate and Arch Linux Arm (not sure about Raspbian).

Apparently Chromium browser was stable through version 48, and the seg fault problem began appearing with version 49. The chromium-browser version in Quirky Xerus 8.0.25 is 52.0.2743.116.

I did a PM to Mike Walsh about the problem, including the error messages. He said that Chromium usually contains cutting-edge work and is compiled against the latest glibc. Google then takes this source code and then alters it as Chrome and re-compiles it against an older glibc to give a new ‘stable’ release compatible with as much hardware as possible. His thoughts were that the problems I encountered were due to conflicts between the ARM porting, the kernel used and Chromium’s source code. I sure wish Chrome were available in the repository.

Interesting…Raspberry Pi just released a new operating system called ‘PIXEL’, and the default browser is chromium-browser 51.0.2704.91. In my limited experience with it, the browser seems to boot without problem and take you where you want to go. But thus far it will not allow me to sign in to my gmail account (“Uh-oh!

Testing version 8.0.25

The sound is much better!!

Audio setup procedure:

Retrovol needed the sliders moved to left hand
side to make active, but sound volume was correct and persisted between boots.

Retrovol didn't need the sliders adjusted so there was no crash.

There appears to be a new bug introduced in this version.
leafpad version 0.8.18 appears to have a bug with some arm kernels
when saving a bash script to disk. It produces garbage characters
making the script unusable. sometimes the files are "application/octet-stream"

Geany doesn't have this problem fortunately.

Fatdogarm version .0.8.17 works OK so replacing may be the solution.

I have bypassed the problem of Retrovol showing bogus sliders in the mixer (and crashing), by using pnmixer and aumix:

I got xine working on the Pi2, but it is very unsatisfactory. Weird error messages, videos don't play, etc.
http://barryk.org/news/?viewDetailed=00432

...also in above link, I reported that ethernet reconnection at bootup is now fixed.

Anyway, the video player. I know that you guys have been trying various video players. Which one do you reckon would be the best replacement for xine?

I guess the choices are VLC, mplayer, xfmedia. Anything else?

The replacement should be something that doesn't have too many dependencies.

[BarryK]

Testing on the Pi2, Shutdown -> Exit to prompt just produces a black screen, and the keyboard no longer responds.

I don't know why, so I have implemented a workaround.

For the Pi only, "Exit to prompt" is replaced with "Reboot to commandline". This works.

I looked at the leafpad website, 0.8.17 is the latest version. I wonder where 0.8.18 comes from?

Latest is 0.8.18.1

I am compiling VLC, with support for the GPU in the Pi:

I also posted links to light-weight GUIs for VLC.

Here is another GUI:

I was able to get omxplayer to work by adding a lot of libraries.

Did you compile that omxplayer-v7-0.3.7.pet, or was it a ready-made binary from somewhere?

I have compiled VLC, without Qt. I did everything recommended for compiling on the Pi2, but when I run it like this:

cvlc --vout omxil_vout big_buck_bunny.mp4

I just get an error message;

"core decoder error: failed to create video output"

However, "sdl" and "x11" work.

[BarryK]

if retrovol is launched from the start menu it creates a speaker icon in the tray.
The icon doesn't disappear when retrovol is quit, so there will be multiple
speaker icons . (see image)

When retrovol is launched from the tray this doesn't occur.

I just re-read this post, I had misunderstood it before.

Yes, you are right, that does happen.

Anyway, now I am using 'pnmixer' for the tray and 'aumix' mixer, two separate apps, so it avoids that problem.

[don570]

Remember to compile mhwaveedit for the new audio mixer

Code: Select all

./configure --with-default-mixerapp=aumixer --prefix=/usr

I stole the whole thing from a media server OS that is available at the
berryboot site. Then I made a few links so that there wouldn't be complaints
when launched at the terminal.

There is a huge number of dependencies so it won't be easy to compile.

I compiled latest nano 2.7 to edit text in terminal. It selects text with arrow keys.
Ctrl-K Ctrl- U will copy text to clipboard buffer. Ctrl - U will paste text.

Yay, vcl now works with the 'omxil_vout' option.

It was simple, vlc could not find the libraries. I added "/opt/vc/lib" into /etc/ld.so.conf, then ran "ldconfig".
For good measure, I also added "/opt/vc/bin" to PATH variable.

Right now I am compiling MPV. ...hey, that was quick, finished. It downloaded latest ffmpeg and compiled the libs statically only, so end up with 'mpv' as one big executable -- 12MB.

And yep, it works.

I am impressed at the speed of 0.8.25 on my rPi2! Great job!
Is wifi supposed to work? I tested two different USB micro adapters in two different wireless networks, with all three connection managers. In all cases the connection managers report that the DHCP client can't connect to the network, this is with WPA security. I know the wifi APs are set for WPA2 security. Is that the problem?

The micro adapters are the Edimax and TP-link 8188eu, which are commonly found on rPis. SID scanning works fine for both adapters and all connection managers.

Then I connected on eth0 and that worked fine. seamonkey as spot worked fine. Youtube didn't show any video placeholders, just text. And while I was browsing another site Seamonkey just crashed.

Like I said I'm impressed with this piece of work. Thank you very much.

I clicked on tray icon and followed instructions.
My USB adaptor driver showed up in list.
