I can't backport conky-all 1.9.0-2 due to a problematic build dependency:
Package libxnvctrl-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
nvidia-settings-updates:i386 nvidia-settings:i386 nvidia-settings-updates
nvidia-settings
E: Package 'libxnvctrl-dev' has no installation candidate
It seems this package is no longer virtual in trusty-backports and later.
