Like I said before in http://plato.cgl.ucsf.edu/pipermail/chimera-users/2019-August/016113.html, you need to use the daily build of Chimera.  Go the Chimera download web page, http://www.cgl.ucsf.edu/chimera/download.html. Scroll down past the 1.13.1 downloads, and pick the 64-bit Linux daily build version to download.  Then install it. When 1.14 comes out, it will not have this problem.     -- Greg On 8/29/2019 11:22 PM, Aleksandra Jarmołowicz wrote:

I am using Ubuntu 19.04. So what can I do to use Chimera with this version? Before update of the system programme runs well.
