Hi Józef,

  OpenGL provides no mechanism for an applications to choose among multiple GPUs, or even know that multiple GPUs are available.  It is up to your operating system to choose the GPU.

Hi Tom,

Thanks. This is weird because I have recently updated to the latest NVidia drivers, which should have fixed this (and it didn't). I have been searching around based on your pointers and I suspect that Windows somehow tells ChimeraX to use the integrated graphics rather than one of the four NVidia GPUs (I guess Intel graphics is the GPU default in the Win installation) I have never checked or tried to update the driver for the integrated graphics so it might be that it is using some ancient generic driver (I just assumed that Windows would automatically directed ChimeraX to the more powerful GPU options). 
I have found some instructions to force ChimeraX to use NVidia GPUs so I will try this (when I can access my workstation again).

Best,
Józef

Hi Józef,

  The reason ChimeraX does not start on hour Windows computer is given in the middle of this error message:

ERROR: ChimeraX requires OpenGL graphics version 3.3.
Your computer graphics driver provided version 1.1
  
Your OpenGL graphics driver is not working.  Version 1.1 is from the 1990s and is what Windows gives you when you have no working graphics driver.  So the fix will be to install a working graphics driver.

  When ChimeraX does not get a usable graphics driver it is supposed to still start and present a message explaining this.  I am not sure why it crashed in your case.  But I see in your error message

Windows fatal exception: code 0x80000003

and searching online this says you have misconfigured Windows system files.  All the top hits when searching for that error look like scams telling you how to use their special utility to "fix" your system.  Be cautious -- I would not suggest running any spacial "cleaner" tools as they are usually malware.

Hi Tom, 

I finally got to run ChimeraX-console with --debug (did not have access to the machine during lockdown) to see why ChimeraX does not start on my system. I am pasting the output below message. Can you give me any pointers on how to make my ChimeraX installation to work. From a cursory look it seems there is a problem with OpenGL implementation.
Any tips would be welcome. I had latest Nvidia studio drivers, now I updated to the latest Nvidia gaming drivers and the problem with starting ChimeraX persists.

Thanks,
Józef

Hi Józef,

  Try starting ChimeraX from a Windows Command Prompt with the debug option

"c:\Program Files\ChimeraX\bin\ChimeraX-console.exe" --debug

and you will probably get a Python traceback which will give some clue as to what is going wrong.  If your graphics driver is not functioning ChimeraX is supposed to show you a window with an error message, but perhaps this has not been tested on Windows.

Hi, 

I am trying to get ChimeraX on a Windows 10 installation on a workstation with 4 GPUs (RTX 2080Ti).
The program installs just fine but when I start it, it shows the splash screen up to Loading main interface and then quits. I have tried both with the 0.92 release and the daily_build.
Any chance you could help with with getting it to work?
Browsing archives I learned that this may be down to some incompatibilities with drivers.
The onboard graphics is ASPEED Graphics Family  with driver version 9.0.10.102
The four Nvidia GeForce RTX2080Ti have driver 26.21.14.4219 installed (I updated to the latest drivers hoping it fixes it - it doesn't).
Any ideas or suggestions?

Thanks,
Józef
