Hello,
I find out a problem with visualization under Leap 42.1 and I 'm
looking 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"
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
DISPLAYMANAGER="kdm"
DEFAULT_WM="kde"
If you call a visualization-program such as blender or even glxgears
locally all is fine ,
but if you do an ssh-login on 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 .
Can anybody help me here? Thanks in advance
Kindly regards
