Hi, I am running Debian Testing with two monitors in portrait mode. I never had a problem with this configuration.
This week, I received a desktop notification telling me that there were updates available that required a reboot. I proceeded, and after the reboot and after introducing my password to enter my session, I got both monitors with black displays, apparently unresponsive.
Ctrl-Alt Fn5 would at least give me a command line (in landscape mode). With this I ran update & upgrade, but packages were all fine.
After trying different things, I created a new user, and then rebooted. With the new user I can log in and I get a GNOME desktop alright (in landscape mode). If I select a display and rotate it, that display will go black.
I have searched for this problem, but the keywords won't help to get results related to this specific problem. Any ideas?

Portrait display goes black after updating Debian Testing
Re: Portrait display goes black after updating Debian Testin
First, do you have inxi installed.
If not install it.
Then run inxi -Fxx so we can see what hardware you have.

Re: Portrait display goes black after updating Debian Testin
It looks like it might have something to do with this:
I don't use GNOME or Wayland so I hope someone else has some insight.
I would say do some more searching on the web.

Re: Portrait display goes black after updating Debian Testin
Thank you, your hint was useful.
I haven't been able to find anything useful (to me) about GNOME, Wayland and portrait screen, but I found an interim (or not) solution, quite simple:
Clicking the cog icon in the login screen, four options are offered:
* System X11 Default
* GNOME
* GNOME Classic
* GNOME on Xorg
The only option that leads to the blck portrait screen is "GNOME" (I assume with Wayland). The other three work.
Now, which one to choose? Is there a reason to choose one over the other apart from UI taste? Classic does look classic. Meh. After a few clicks, I don't see any difference between X11 and Xorg. I haven't been following the X* / Wayland discussions for a long time...
