i have a hard time understanding this paragraph.

your hardware problems are a totally unrelated issue.
i understand that this issue is the reason why you are mixing both
"stable" aka "jessie" (which seems to work fine for you) and "testing"
aka "stretch" (picking the parts you want updated).

but this doesn't mean that Debian supports such a setup, (and as a
consequence: that bugs caused by this setup are valid).

furthermore, you have plenty of other repositories outside of debian
some of them are known to make problems (e.g. deb-multimedia), that's
why you might get heated replies about them.
others are from other distributions (e.g. linuxmint).
others are totally unknown.

if you have only a single package installed from any of those
non-Debian repositories, this package might depend on a certain
version that is *conflicting* with an official package like 'inkscape'
as found in testing, making it uninstallable.

so who do you think is to blame?

so to conclude:
a large eco-system like an entire operating system with thousands of
libraries and applications is a complex system.
it takes a lot of man power to make all its components work together.
Debian does this work.
if you (the user) deliberately replaces some of it's components, then
Debian cannot be held responsible for any damage you do to your system.

that's why your bug report is considered invalid and has been closed.

the good news is: even though you have tampered with your system, it
still is consistent (everything works). it just won't let you install
things that are known to break your existing setup (this is the actual
reason why you cannot install 'inkscape').
/this doesn't mean however, that

there *is* a way to install newer versions of (selected) packages on a
"stable" system. it's called "backports", and provides specially buit
packages that integrate into e.g. "jessie".


note however, that backports only provides a small subset of the
~50000 packages available in Debian.

and of course (to reiterate what others have already said): if you do
want to have support from Debian, you need to first /use Debian/: that
means uninstalling all packages from unofficial (wrt Debian)
repositories and disabling all unofficial repositories.
