OPEN_GL and NVIDIA

[jhjun724]

Hi! I'm really interested in your SUMA and SUMA++ and I'm trying to run it on my computer. It was successful to build. Thank you for your posts. But there was a problem in visualizer. I think this problem caused with my computer(without graphic card). I want to ask you that my guess is right.

$ glxinfo | grep "version"
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Max core profile version: 4.6
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.2
OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.0.8
OpenGL core profile shading language version string: 4.60
OpenGL version string: 3.0 Mesa 20.0.8
OpenGL shading language version string: 1.30
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.0.8
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
    GL_EXT_shader_implicit_conversions, GL_EXT_shader_integer_mix,

Here is the result of version check and

~/catkin_ws/src/SuMa/bin$ ./visualizer 
OpenGL Context Version 4.6 core profile
GLEW initialized.
OpenGL context version: 4.6
OpenGL vendor string  : Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 530 (SKL GT2)
Segmentation fault (core dumped)

this is the error message. I didn't try SUMA++. This problem is related with SUMA which is uploaded on github.com/PRBonn/SuMa. But there was no issue link, so I'm asking here.

Thank you.

Hey @jhjun724, I never tried our method without an Nvidia graphic card (facepalm). Since our method is based on OpenGL shaders, I guess it would be very hard to make it work without a graphic card.

@jbehley Jens, do you have any comments on this?

Thank you for your answer!

@jhjun724 When you install Nvidia driver, don't add '-no-opengl-files'. When you reboot, you will find you can't open you ubuntu. This is true. Here, don't select 'Ubuntu' but 'Ubuntu on Wayland' cd /etc/X11 Backup 'xorg.conf'. Then, set 'xorg.conf' like this: https://forums.developer.nvidia.com/t/opengl-doesnt-use-nvidia-drivers-on-ubuntu-18-04-uses-llvmpipe/126084/4

Section "ServerLayout" Identifier "layout" Screen 0 "nvidia" 0 0 EndSection

Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Fake" HorizSync 15.0 - 86.0 VertRefresh 60 Option "DPMS" "False" EndSection

Section "Device" Identifier "nvidia" Driver "nvidia" VendorName "NVIDIA Corporation" Option "ConnectedMonitor" "DFP-0" Option "AllowEmptyInitialConfiguration" EndSection

Section "Screen" Identifier "nvidia" Device "nvidia" Monitor "Monitor0" EndSection

Reboot and you can select 'Ubuntu' and can go in! Next, you need sudo apt install nvidia-settings sudo apt install nvidia-prime When you input 'nvidia-settings' you can find this: Congratulations!
