Thank you for reporting this. There is a missing dependency on the libxcb-xinerama0 package. Please install it with: sudo apt install libxcb-xinerama0 and then try ChimeraX 1.2.5 again. This bug is also present in the current Ubuntu 18.04 and 20.04 downloads. It will be fixed within 24 hours. -- Greg On 6/13/2021 7:31 AM, Zhou, Bing-Rui (NIH/NCI) [E] via ChimeraX-users wrote:
Hello ChimeraX developer,
I am trying to update ChimeraX from v1.1 to v1.2.5 on a Ubuntu 16.04 Linux machine, but Chimerax v1.2.5 failed to start with the following error message:

I could downgrade to ChimeraX v1.1 and it works fine, just wondering what has changed in v1.2.5 and if there is a fix for this issue.
Thanks,
Bing-Rui
