Title: having issues starting jriver on debian VM via VNC client
Post by: stevemac on January 17, 2017, 05:26:17 am
Hi,

Preface this with - I do not have good *NIX skills & am out of my depth.  Appreciate some help if anyone has time

Background

When I need to access JRiver for tagging or other admin work I do so via a VNC client (TightVNC Viewer) on a Windows machine.  The VNC client is using the IP address allocated to VirtualBox installation and the port allocated for the debian guest within VirtualBox (eg 192.168.2.150:9000).  This works but the screen resolution is poor & it takes a lot of time to do things.

I thought about installing vncserver on the debian VM and accessing it directly (instead of via VirtualBox).  So

Code: [Select]
Jan 17 21:58:20 deb64vm001 kernel: [   105.948190] mediacenter22[1358]: segfault at 10 ip 0000000000eb1799 sp 00007fff713075a0 error 4 in mediacenter22[400000+1185000]

I'm at a bit of a loss at what to check / look at.  I'm guessing I have setup vncserver incorrectly, but not skilled enough to progress further. Any thoughts?

Appreciate your help & sorry for the complex setup

Cheers,

Steve

and some further info

if I start mediacenter22 from a terminal session via the TightVNCViewer I get the following

Code: [Select]
Xlib: extension "RANDR" missing display on ":1.0".
Segmentation fault

cheers,

Steve

If you use Authentication on the Linux Server, you could use another copy of MC on another machine to do tagging.

It's a known issue that's been happening that Bob's aware of. I think this might fix it - try installing these in Debian where MC is running from;

Code: [Select]
sudo apt-get install libxrandr2 x11-xserver-utils

Thanks Jim

Authentication already enabled

made tag change & selected sync changes with library server & it worked.
then created a playlist, synced & playlist available on library server

that addresses the more common reasons for needing to access the VM.  Appreciate it

Steve

Just did some testing on this and the issue appears to be the vncserver on the linux side. By itself it doesn't support xrandr which is necessary for multiple monitors and has been part of MC's requirements since theaterview was added.

What I do here is use the dummy xserver and x11vnc on top of that. It works without any issues. Can even use remote desktop protocol with xrdp as well.

Hi Bob,
we are running into issues as well. We were using just using vncserver on our (console only debian 8) linux machine in the past, which now fails with latest mediacenter.
I followed your instructions here to install xserver-xorg-video-dummy and x11vnc (https://yabb.jriver.com/interact/index.php/topic,109419.msg757258.html).

Should these steps still work without any problems?
I installed both packages (with all prerequisites), updated the xorg.conf, but the x-server won't start with the dummy device.

It should.
How are you trying to start it?

Hi Bob,

I got it working.

I expected that the x-server will start automatically with existing xorg.conf.

I just needed to start the x-server with "sudo Xorg :0" and everthing works fine.

Thanks
