Debian 9 amd64 20170403 installation leaves my HD6790 system with unusable X
Hello to the Debian installer developers, once again, this 4head card is
unusable in Debian. It would not work at all on Debian 7 (bug #747218)
while it worked on Debian 8. Now it fails to work on Stretch.
This time Xorg cannot start at all UNLESS firmware-amd-graphics is
installed from command line.I did not file a bug report since I do not
want to run reportbug from cli. If the card is unusable on Debian 9
without the firmware why didn't the installer ask for it?
I must also remind you that the kms cannot be turned off since 3.9(?)
kernels and that was a quick solution on Debian 7,8.
In case the installer team wishes to add f/w request code, the pci
device id is 673e.
I am almost certain that many other amd gpus will have the same problem
and I will check some of my own cards later this week.
