Hello, Xvfg seems to be unmaintained. I've got some good results with XDummy.
First I made sure OpenGL is installed with xdummy
yum install mesa-libGL mesa-dri-drivers xorg-x11-drv-dummy xserver-xorg-video-dummy
I then created a config file for XDummy (dummy-1920x1080.conf)
Section "Monitor"
Identifier "Monitor0"
HorizSync 28.0-80.0
VertRefresh 48.0-75.0
Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync
EndSection
Section "Device"
Identifier "Card0"
Driver "dummy"
VideoRam 256000
EndSection
Section "Screen"
DefaultDepth 24
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Depth 24
Modes "1920x1080_60.00"
EndSubSection
EndSection
I then started Xdummy on the server
sudo X :99 -config dummy-1920x1080.conf
Once the server started, make sure you export the environnement variables
export DISPLAY=:99
export MESA_GL_VERSION_OVERRIDE=3.2
After than I managed to run a python program that was using VTK
python headless.py
Note that for pyvista, you might need to export some additionnal env variables
export PYVISTA_OFF_SCREEN=true
export PYVISTA_USE_IPYVTK=true

Hello, I understand this topic has been discussed few times. Wondering if anyone made it work on a headless virtual machine with Centos OS. All I am trying to do is to load existing vtk files and put them together as a gif animation. I have installed Xvfb and mesa-libGL. Also, created a shell script to config Xvfb
But still when running the python script, it tells me 'could not find a decent visual'
I have checked that there is a xvfb process running in the background:
Can you tell what i missed and where i did wrong here?
Thanks!
Junting
