Running a Mac Pro, OS X El Capitan 10.11.4 With ATI Radeon Graphics card, and XQuartz v 2.7.9
I am able to run qdec and freeview perfectly fine on my machine. The problem comes when I attempt to SSH into an Ubuntu 12.04 (Nvidia GeForce GTX 650) machine and use these programs (it used to work fine, but I am wondering if something in our configuration has changed now)
I get the following errors after ssh into the Ubuntu machine.
[myuser@ubuntu-machine:~] freeview Xlib: extension "NV-GLX" missing on display "localhost:10.0". X Error: BadValue (integer parameter out of range for operation) 2 Extension: 150 (Uknown extension) Minor opcode: 3 (Unknown request) Resource id: 0x0 Abort (core dumped) [myuser@ubuntu-machine:~] qdec Xlib: extension "NV-GLX" missing on display "localhost:10.0". X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 150 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 1504 Current serial number in output stream: 1505
Based on my limited knowledge, It seems likely to be a problem with X / SSH, and the graphics card, but I am unsure on how to proceed from here. If anyone has any ideas on how to overcome this, I would be incredibly grateful!
The Ubuntu machine itself also has a monitor, and can run qdec and freeview fine locally, with no problems. the issue seems to happen over SSH. Some programs on the Ubuntu machine will work correctly this way (but they complain loudly in the background terminal about X)
The Mac recently updated XQuartz but I am not entirely sure if this problem was happening before the update or not.
ssh -y but this returns the same error.
export LIBGL_ALWAYS_INDIRECT=1 after SSH into the Ubuntu machine, but still get the same error.
The official question: What do these errors mean, and how can I attempt a fix?
