Hi, I have a Dell R720 server running RHEL 8.5 with Ansys 2021R2<\/p>\n

This has the standard Matrox graphics card on the m\/b but has a Tesla K40c GPU. I connect to it using Xming from a PC with a Quadro card in it. <\/p>\n

Issue with trying to edit the Geometry. Unable to start.<\/p>\n

GLXgears runs OK. Ansys WB starts up OK. Fluent starts OK and can see the GPU. It does report "Direct rendering unavailable, hardware acceleration will be disabled." which is fair enough.<\/p>\n

Relevant output from lspci is <\/p>\n

05:00.0 3D controller: NVIDIA Corporation GK180GL [Tesla K40c] (rev a1)<\/p>\n

0b:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. G200eR2<\/p>\n

And<\/p>\n

 lspci -nnk | grep -i vga -A3 | grep 'in use'<\/p>\n

    Kernel driver in use: mgag200<\/p>\n

glxinfo | grep -i "opengl renderer"<\/p>\n

OpenGL renderer string: Software Rasterizer<\/p>\n

Running the CUDA samples finds the GPU ok. This driver is at the 460.106.00 revision.<\/p>\n

Tried using the mesa drivers in the Ansys directories.<\/p>\n

Any way of getting this to work?<\/p>\n

I suspect if the Geometry editor is trying to use an OpenGL card on the system then the Matrox card won't do this and the K40 running in TCC mode won't do it either. I was hoping it could be used for frame buffering. I'm going to fit another Quadro card in it to see if this makes a difference when I get the chance. Obvs, I won't be connecting a monitor to it..<\/p>\n
