comment:3 by Tom Goddard, 3 years ago

It looks like you are running Linux with Wayland. That is probably what causes this OpenGL graphics error at startup. We put a fix into the ChimeraX daily build a few weeks ago for this problem. Try the ChimeraX daily build and please report if that worked. Thanks!

Tom,
Thank you for your response.
I tested chimerax-daily version 1.4 on the same wsl2 ubuntu 20.04 system and Ryzen5-RADEON platform with newest adrenaline driver.
After installation, following message was output. 
After typing chimera-daily, the main window was popped up, but small popup-windows were sticked left top-conner and did not move. Same thing was also observed at ver1.3.

Comment (by Tom Goddard):

 It looks like you are running Linux with Wayland.  That is probably what  causes this OpenGL graphics error at startup.  We put a fix into the
 ChimeraX daily build a few weeks ago for this problem.   Try the ChimeraX
 daily build and please report if that worked.  Thanks!

That's my fault. We are in the process of reorganizing some of our source code. I will have a fix in tomorrow's daily build.

Moved most of core/__main__.py into core/__init__.py since, as far as I know, it's at least inconvenient (if not impossible) to import code from a module's __main__.py so it should stay pretty minimal. See tkinter/__main__.py

I'll look closer later, but ouch. Sounds it like it would be better to put main in its own package for now. Perhaps chimerax/main/init.py. Besides, it's easy to import: from chimerax.core import __main__.

comment:8 by Zach Pearson, 3 years ago

I'm not sure that's the case. On my machine:

ChimeraX git:(develop) Ⲗ ./ChimeraX.app/bin/python3.9
Python 3.9.11 (main, Jun 17 2022, 14:27:48)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from chimerax.core import __main__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name '__main__' from 'chimerax.core' (/home/zjp/ChimeraX/chimerax/core/__init__.py)
>>> import chimerax.core.__main__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'chimerax.core.__main__'
>>>

Not even in ChimeraX's own shell using the old location:

from ChimeraX_main import __main__
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

----> 1 from ChimeraX_main import __main__

ImportError: cannot import name '__main__' from 'ChimeraX_main' (C:\Program Files\ChimeraX 1.4.techpreview202202250804\bin\lib\site-packages\ChimeraX_main.py)

You can import __main__ from the shell, but if you type __main__. and press tab it looks like the only useful attribute that it has is the session.

I guess the ChimeraX Linux daily build installer is broken. Hopefully it will be fixed tomorrow. You will need a daily build created June 21, 2022 or later.

Hi,
I tested the newest chimerax-daily.deb(built: 2022-06-22 03:28:47 PDT).
Installation does not have any problem.
After starting, small pop of bug report attached at the left top conner. I could not make it move nor input any word, even nor press cancel.
I tried to type "open mypdb.cif" in the appearing command line under the main window.
However, the window was closed down with a message of Segmentation fault.
Kama

Resolution: fixed
Status: assignedclosed

The original OpenGL error was fixed by using a daily build.

I made a new ticket #7151 for the subsequent problems.
