What installation method did you use? I have an XU4 and have been struggling for weeks now. I cannot get GQRX to open, there is some error with X11 when you use the standard method...

Hi,
I am putting an odroid xu4 on a hill with a bunch of antennas and wish to have a permanent remotely-usable Linux SDR system on the hill as well, so I can confirm RF is working.
My odroid starts headless, then I bring up X and Mate on demand by using X2Go from a windows machine. Everything works, but sadly when I have a X2Go client running Mate and I try start up GQRX I get this error :-
odroid@odroid:~$ gqrx
linux; GNU C++ version 5.3.1 20151219; Boost_105800; UHD_003.009.002-0-unknown
linux; GNU C++ version 5.3.1 20151219; Boost_105800; UHD_003.009.002-0-unknown
failed to get the current screen resources
The X11 connection broke: Unsupported extension used (code 2)
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":50"
after 6 requests (6 known processed) with 0 events remaining.
Segmentation fault

XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":50"
after 6 requests (6 known processed) with 0 events remaining.
Segmentation fault
The display the X2GO client is using is actually no 50.
Running Ubuntu 16.04.2 LTS (Xenial) fully up to date.
Installed GQRX (with no errors) using the standard PPA procedure.
X2Go latest version, using NX3
Installed as per here
Any tips?

Did you set/export the display before starting gqrx?

The website says with bold letters that it only works with i386 and
amd64 processors and shoyuld not be used on ARM.

Oh.
Well it works perfectly on my pine64, even if it's a touch slow. One I saw it working on the Pine I went 'Aahhh Ha!' and thought of running it on the Odroid :) Actually, just today I used the Pine64 and GQRX to identify which were the best digital TV antenna cables out of a sizeable pile... ;-)
Thanks for replying though.
If you have a minute, I am not sure what you mean by "Did you set/export the display before starting gqrx? "

Yep, that last post was probably a hint at the problem. X2Go only supports GLX1.2
at
extract:
According to http://wiki.x2go.org/doku.php/doc:de-compat , X2Go just does not support GLX 1.3 and will not do so in the near future because it means rebasing their fork of the ancient X.Org 6.9 to something much more recent. This is unfortunate because several parts of Qt 5 require GLX 1.3 (not just QtWebEngine, but also QML2). (The generic workaround is
export QT_XCB_FORCE_SOFTWARE_OPENGL=1. But for QupZilla, qupzilla --disable-gpu is almost certainly more efficient.)and
extract:
This been a long time I want to use Qt5 on my QML application, but there was that bug. Now Qt5.5 is live, and I still can't use Qt5 app on X11 ...
I develop only on Ubuntu or Debian VM with no screen, so I use SSH and X11 forwarding (Xming and or MobaxTerm).
My app is fully working under Qt4.8, and works on Qt5 if not throught a virtual screen (tested on an imx6 card on screen without any problems)
I've compiled Qt 5.5 sucefully
My take home point is that, assuming you are using QT5, with components that rely on GLX 1.3, the current version of GQRX just won't work over X2Go, where it starts an xsession on demand on what is usually a headless server.
It seems that QT4.8 might work, so on I go to find some rtl-sdr app that uses the older QT versions. If I don't fall asleep I'll report back.
Hope this helps,
X

Hello Xenek,
Curious, do the modern versions of NoMachine work for Qt5? Have you considered some of the RDP server solution for Linux as an alternative?

I'll try over the next few days or so... I broke x somehow and now it only starts remotely :( Might need a rebuild!

Actually it was first recently that we started to require Qt 5.
Versions prior to 2.6 might compile fine with Qt 4.8.

It looks like I won't find a remote xwindows client/server combo that will run QT5. A couple of systems have active projects that will support GLX 1.3 (and so QT5) but neither are complete nor have a trial release.
Either I use a different rtl-srd product or recompile an older version, as suggested, that will be static.
Would be great if someone reading this who knows the best way to install Gqrx 2.5.3 with Qt-4.8.4.. Do I have to compile or can I get away with a series of apt-get commands?
I think that version is probably a good candidate to try.
Cheers,

Xenek,
have you tried XPra https://xpra.org/ ?
i sometimes use it to run gqrx remotely on my headless arm-box.
But my arm-box is running archlinux arm with qt5 5.8.0-7, and grqx built from git..

No, didn't try that Robert. But I am very, very very pleased to report that nomachine for arm 7 works perfectly. Unbelievably quick, totally no comparison to x11vnc or realvnc. Those are, in my opinion, relegated to the 'emergency' department. X2Go was quick, but not this quick, and the latest GQRX wouldn't run over it, unlike nomachine.
nomachine works so well that I can run the system monitor showing CPU usage, while playing a youtube video, while scanning with GQRX, and not fill all cores on the 8 core Odroid XU4 microcomputer. It's seamless, just about like being there. There is of course an almost imperceptible lag, but it's so tiny that I only mention it in the interests of being anal. The Mjpeg on the video is visible, but it's fast enough that the slight drop in quality isn't an issue. It works.
Nomachine was easy to install, easy to run, it has a discovery, and is easy to use.
Only catch will be when I put the device behind a couple of nats, I can't use the NM protocol over port 4000, and will instead want to tunnel SSH via a bridge server of some sort. That is yet to be done, but what I have seen so far gives me great hope. Crossing fingers.
It looks like I can run now GQRX via a wifi bridge kilometres away, and scan my Lorawan packets, happily, even if I can't access it from 100 kilometres away via 4g, wifi bridges & VDSL2 :)
Cheers to all,
X
