I am on latest 9.0 testing,
My box has a 970 nvidia, and i was forced to use 375.26, directly via the nvidia installer, which works as expected.
otherwise, the card is developing "garbage" similar to a RAM issue well known to some folks without luck, if I go with crap from what the Debian apt factory provides, the x session freezes, hard reset is required to get the window manager back. This happens after running the system idle, for at least one day or so.
I am wondering what is the process before feeding such non-free trash to Debian users... some of us might post such equipment on fleabay, as non-working, for 20 bucks as a result.
I understand, open-source will be monitored 100x better than proprietary crap, but this should not even appear in testing, and confuse the hell out of people.
