less color depth possible?
Hi all,
We are trying to set up cryoEM data processing in the university HPC. We use X2go for remote accessing the HPC, but it doesn't have enough color depth, so Chimera (24-bit) doesn't start.
One workaround is to download the volume from HPC to local machine, but it is less convenient. But I wonder is there a way to use Chimera in less color?
Thanks a lot.
Best,
Tat
Hi Tat,
Chimera has no controls for color depth. I guess its OpenGL rendering asks for 8-bit color depth for the OpenGL context. What error does Chimera give? Using less than 8-bit color depth for visualization is absurd. X2Go must be able to do 24.

Hi Tom,
Thanks for your message. Here is the error message. I am confused as well, because X2go should be running at 24 bit as I read from the internet.

Tat,
To use ChimeraX with x2go, you need to install virtualgl and then use "vglrun chimerax" to run ChimeraX. The problem is probably not the 24-bit visual, but the OpenGL support.
