"dnf search libxss" shows that the missing package on RHEL/CentOS/Rocky/Alma 9 is the libXScrnSaver package.   So someone needs to install that package.   If you are a system administrator for that computer, run "sudo dnf install libXScrnSaver". And remember, Chimera is no longer being developed or supported (except for easy things like this).  If you can, you should switch to ChimeraX.     HTH,     Greg On 3/23/2024 12:48 PM, Evan Kantrowitz via Chimera-users wrote:

Hi All,

    I am trying to move our viewmotions.bc.edu <http://viewmotions.bc.edu> server to a new server running Centos 9.  I downloaded the most recent chimera (chimera-1.17.3-linux_x86_64.bin <https://www.cgl.ucsf.edu/chimera/cgi-bin/secure/chimera-get.py?file=linux_x86_64/chimera-1.17.3-linux_x86_64.bin>).  Followed the install procedure with no issues.

When I ran chimera I got these errors, both in commandline mode or regular. Any help would be appreciated.

Thanks
