[opensuse-kde] Configure indirect rendering for X under leap 42.1
Hello, I find out a problem with visualization under Leap 42.1 and I 'm looking for an option for a permanent configuration of indirect GLX for example in /etc/sysconfig/displaymanager. Under Leap 42.1 the X-Server behaves as if AllowIndirectGLXProtocol = FALSE and because of this OpenGL-Applications don't function per SSh and X11-Forwarding I did some of the proposed configuration i found in the web. 1) Change /etc/X11/xdm/Xservers to :0 local /usr/bin/X -nolisten tcp +iglx -br vt7 But after "rcxdm restart" this option +iglx is not shown in the Xorg-command with ps 2) Change of etc/X11/xorg.conf Section "ServerFlags" Option "AllowIndirectGLX" "on" or "True" and Option "AllowIndirectGLXProtocol" "on" or "True" EndSection despite of this glxgears shows direct rendering : Yes ------- Our constallation of several workstations is : Leap 42.1 Kernel : 4.1.34-33-default x11-video-nvidiaG04-367.57-27.1 xorg-x11-server-7.6_1.17.2-24.2 libva-glx1-1.6.0-3.2.x86_64 libxcb-glx0-1.11.1-1.1.x86_64 DISPLAYMANAGER="kdm" DEFAULT_WM="kde" If you locally login with session "KDE Plasma workspace" and call a visualization-program such as blender or even glxgears all is fine , but if you do an ssh-login to the other workstation and even call glxgears , an error occurred. X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 154 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 30 Current serial number in output stream: 31 It seems to be a problem with direct rendering , you should install indirect rendering. Can anybody help me here?

The nvidia driver doesn't support indirect OpenGL rendering at all AFAIK. So I see no way to fix your problem except uninstalling nvidia. It may work if you connect via VNC though, by running "x11vnc" inside a running desktop session and connect to that. This is not really related to KDE though...
