ubuntu opengl not supported
I connect to my azure ubuntu server using tightvnc and open the terminal.I check if opengl is supported using the fallowing command.
-
First command using "glxgears" The results Error: couldn't get an RGB, Double-buffered visual
-
Second command using "glxinfo" The results name of display: :1.0 Error: couldn't find RGB GLX visual or fbconfig
Is this mean that my ubuntu server doest not support opengl?
Also I tried to install QT creator to ubuntu server. I tried to create project and run it. I get error like
GLX extension not found
screen shot.
Is this graphics driver issue? how to fixed this

just as a note:
tightvnc as far as i know, does not support openGl.
only VirtualGL and TurboVNCAlso indicated by glxgears not running.

@jhovarie First question is: does your app have an UI?
Usually you don't run UI apps on a server.
If your app does not have an UI then remove "gui" and "widgets" from "QT +=" in your pro file. Rerun qmake and rebuild.@jsulm said in qt ubuntu opengl not supported:

Hi
Sorry i dont know what it is.
however, BadMatch and X_PutImage on google
seems to talk about color depth.
Make sure to read the docs
https://virtualgl.org/vgldoc/2_1_1/
and check color depth if your X session etc.
