Hi, Chimera community. I have seen similar problems addressed, and the solution is always to update drivers and make sure there is only on OpenGL renderer. I am unable to resolve my problem this way. When Chimera is launched using my dedicated NVIDIA 3060 Mobile graphics card, there are mixed results. If launched from a terminal instance an by the NVIDIA card, it produces the error below. Display misconfiguration. Please increase the color quality (24 bit color or greater), update your display (graphics) driver, and/or upgrade your graphics card. Also see chimera installation instructions. Using primusrun, it succesfully launches on the dedicated card. Unfortunately, the nvidia-primus and bumblebee-nvidia packages seem to conflict with the NVIDIA drivers. The only way Chimera works reliably is by launching it through an instance of Steam ran on the NVIDIA card. The Steam client opens ~/.local/bin/chimera, the same file opened through the terminal. I am not sure what is so special about launching an application through Steam. Thanks! W.
