Greetings:

Many years folding, updates to kernel series 6. suddenly FAHControl launch from icon is broken. Processor status shows FAH threads running and reporting results normally. Click on icon does nothing.

Running FAHControl from command line provides the following error results:

pcwolf@B550:[/usr/bin]$ FAHControl
Traceback (most recent call last):
File "/usr/bin/FAHControl", line 25, in <module>
from fah import FAHControl, load_fahcontrol_db

from ._cairo import * # noqa: F401,F403
ImportError: /usr/lib/python2.7/site-packages/cairo/_cairo.so: undefined symbol: cairo_tee_surface_index

Any clues on what broken and how to repair?
Thanks in advance

It looks like this updated version of Manjaro has removed support for Python 2.7. Some distros have that version of Python available as a legacy install, don't know if that is an option for you.

An option that exists for newer versions of Linux with only support for Python 3 is - https://github.com/cdberkstresser/fah-control. They took the open source for FAHControl and recoded it to work with Python 3.

Solved by rebuilding python2-cairo from AUR.
