Thread: VNC server on 42.1 - currently no way?

  1. #1

    Unhappy VNC server on 42.1 - currently no way?

    Hi everybody!

    I use VNC servers on opensuse 13.1 / 13.2 for headless or normal remote access. But with 42.1 Leap I didn't get it work yet. vncserver starts a server, I can connect remotely, enter password, but the desktop on the remote computer stays black, error report, Plasma crashed (although in xstartup kde ist started?!?):

    Error log has GDEpolicy.kit error, as there are more than half a dozen pol-manager onboard in LEAP (wow...)...

    Anybody out there successful using VNC server on LEAP? Any help highly appreciated

    Kind regards

    Ok, changed the startup script to:

    The server log looks like:

    (too large... fu*cking forum policy, no attachments allowed...)

    Can't open display, surprise, surprise! BUT WHY? :-(


    Started vncserver (tigervnc) both, as user and as root, didn't make much difference at all...

    ...as I use the nvidia legacy driver, might this here be remotely related:

    ...?

    Yes, this is apparently the problem with the plasma desktop crashing 3 times in short succession:

    ...
    kscreen: Primary output changed from KScreen:utput(Id: 60 , Name: "VNC-0" ) ( "VNC-0" ) to KScreen:utput(Id: 60 , Name: "VNC-0" ) ( "VNC-0" )
    QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
    Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize 8, stencilBufferSize 8, samples -1, swapBehavior 2, swapInterval 1, profile 0)
    Application::crashHandler() called with signal 6; recent crashes: 3
    ...

    Afterwards the VNC server is started, which runs perfecty, but with no desktop it makes no sense at all.

    Anybody out there knowing how to fix this OpenGL thing here?

    Any help highly appreciated

    Many thanx in advance

    Default Re: VNC server on 42.1 - currently no way?

    Now I’m not sure if my problem have anything to do with yours. My problem started maybe 1.5-2 weeks ago. I cant use KRDC or Remmina from Leap42.1 clients to connect to my 13.1 server any longer. The connection window just disappears(on the client side).
    It is impossible to start remote control in YaST2(ok the server swallow it but if you reopen the function again it's still disabled).

    So what may be wrong? I have no idea, here is how the /root/.vnc/servername:3.log look in the 13.1 server after have run the command vncserver in a terminal:

    Code:

    The X11 connection broke (error 1). Did the X11 server die?

    I can use the clients to connect to RDP servers (even linux WM's under Virtualbox) and I can use a web browser to connect server ip:5803 (13.1 server(but not the 42.1)). I havent try to put any energy in to it but it semms that the vnc client have some problems as well.

    Anyone else with similar problems? Maybe time for a bug report then.

    regards

    Hej!

    My VNC connection works just fine, but the plasma desktop to be served by VNC just crashes...

    You should have a look at the startup log for the server (for VNC it'S in /user/.vnc).

    God jul! :-D

    Your problem here is that the nvidia driver breaks Mesa, and in particular Mesa's software OpenGL renderer, because it replaces some of Mesa's libraries with incompatible versions.
    Plasma5 (and parts of Qt5) *requires* OpenGL though.
    You'd probably have the same problem with GNOME.

    The only way around that I am aware of is to uninstall the nvidia driver and use nouveau.
    Or use a different desktop that does not depend on OpenGL...

    Thanks, this was what I was fearing...

    But you remember that the NVIDIA driver was the resolution for this here?

    Well, if you want to use Plasma5 (or GNOME) over VNC, that is.

    The only real solution would be if nvidia finally really would support the nouveau development as they promised a year ago.
    They did a bit, but so far only for some (quite new) chipsets AFAIK...
