OS: Linux<\/span>
Distribution: Ubuntu 22.04<\/span>

I have installed the ANSYS 2023R2 on my system. When I run fluent I get the following problem:

\"\"<\/a><\/span><\/p>\n

 <\/p>\n

I have tried following possibilities:
- FLUENT_LAUNCHER_OPTIONS=-driver x11n<\/a>
- ANSGPU_OVERRIDE=1<\/a>
- run fluent with driver option: \"fluent -driver nvidia\" \/ \"fluent -driver amdgpu\" \/ \"fluent -driver radeon\"
- Replacing GPU ( AMD Radeon HD6450, GeForce GTX 590 )
- Repository drivers \/ Manufacturer drivers
...none of those worked.

And the unbeliveable information is that on the same hardware ( better or worse GPU ) BUT, on SUSE-Linux everything runs well.
