Doc Type: Known Issue
Doc Text:
GV100GL graphics cannot use correctly more than one monitor Due to missing signed firmware for the GV100GL graphics, GV100GL cannot have more than one monitor connected. When a second monitor is connected, it is recognized, and graphics set the correct resolution, but the monitor stays in power-saving mode. To work around this problem, install the *NVIDIA* binary driver. As a result, the second monitor output works as expected under the described circumstances.

I tried different monitor with the same resolution but still the same

Comment 2 Tomas Pelka 2018-08-31 10:08:26 UTC
I basically can see the same messages when booting with no screen attached and than plug just one monitor in. The result is the same, so black screens or rather  monitoring just reporting it is switching to powersave mode but xrandre seems to be happy:

Hi Tomas,

This bug is on the list of candidates to be documented for RHEL 7.6 Release Notes.

Please, could you provide initial info in CCWR structure (cause, consequence, workaround, result) to document this bug?

Thank you!

Marie

Comment 8 Tomas Pelka 2018-10-19 08:05:48 UTC
Well this is a consequence of Bug 1457161, due to missing signed firmware for this particular graphics it can operate only using just single monitor output. The workaround is installing/build nvidia binary driver.
