i have a remote-host (ubuntu 20.04),
and a local-host (win10 pc, with nv rtx3050ti gpu, updated driver), i started vcxsrv on local-host by(win\cmd):
vcxsrv.exe -multiwindow -clipboard -wgl -ac
then with win\cmd on local-host, i ssh to remote by:
set DISPLAY=localhost:0.0
ssh -Y username@remote-ip
i don't know why it first need set DISPLAY... in cmd then ssh -Y, but it works for the started vcxsrv to display something, e.g., xclock or rqt (one of ros2's gui tools) will display as expected on local-host.
but when i try to start rviz2 (another ros2's gui tool), on ssh\bash i got error like:
...
[ERROR] [1665571456.729849309] [rviz2]: RenderingAPIException: OpenGL 1.5 is not supported in GLRenderSystem::initialiseContext at /tmp/binarydeb/ros-galactic-rviz-ogre-vendor-8.5.1/.obj-x86_64-linux-gnu/ogre-v1.12.1-prefix/src/ogre-v1.12.1/RenderSystems/GL/src/OgreGLRenderSystem.cpp (line 1201)

among which, the key-error should be:
RenderingAPIException: OpenGL 1.5 is not supported in GLRenderSystem
i understand it's something with the opengl version, so i checked the followings, but still found nothing can further do, any help would be appreciate, thx:
glxinfo -B in the ssh prompt(ssh\bash) on local-host(with set DISPLAY... and ssh -Y):
libGL error: No matching fbConfigs or visuals found

then as some suggested, i tried (on ssh\bash)
export LIBGL_ALWAYS_INDIRECT=1
export MESA_GL_VERSION_OVERRIDE=3.3
then got (libGL error disappeared)

i know nothing much about how x11/vcxsrv/opengl works, but don't understand why the opengl version is different when i check directly in remote-host or with ssh in local-host.
since other graphic-ui could displayed as expect(xclock, rqt of ros2), but rviz2 of ros2 could not, i think it's the dependency of rviz2 with opengl, but why and how to ensure the right opengl version for my case/env?
thx
