[chimerax-users] Difficulties running ChimeraX

[Greg Couch]

Did you install ChimeraX 1.4 or 1.3?  We did a major upgrade of the UI 
toolkit in 1.4 and that might be the issue (we went from Qt 5.15.2 to 
6.3.0).  The ChimeraX daily build has a newer version (6.3.1).  So 
please try out the daily build and let us know if that fixes the problem 
for you.

On Windows, the common solution for bugs like this is to update the 
graphics driver.   That is less common on Linux, but still a 
possibility.  If using the daily build doesn't work, then please send me 
(just me) the output from "lspci | grep VGA" and the output from the 
glxinfo command (you might have to "sudo apt install mesa-utils" to get 
it).  And we'll go from there.
