Hello everybody,
I am running Debian "Sid" on a desktop PC with the "AMD ATI FirePro
W5100" graphics card. When I connect a second monitor, Debian recognizes
it but the monitor stays black. I can even move windows on it, but I
cannot see them.
On the same computer is a Windows 10 partition on which the connection
of both monitors works without problem.
I have installed all drivers like described here
https://wiki.debian.org/AtiHowTo . I also tried to install the
proprietary driver from the AMD website. Everything without success.
Do you have any idea what the problem could be?
I am happy about any hint.
Thanks and best wishes,
Jakob
