This isn't a super serious problem, more like a QoL thing.

I have Debian 13 with KDE. I have a second monitor that is rotated 90 degrees. In KDE I have set the system so that the monitor orientation is correct, and it works fine. The "problem" is, the orientation only becomes fine upon logging into KDE for the first time. During boot and before logging in, the computer still thinks the monitor is in its standard orientation, so everything on the screen is sideways.

So my question is, is there a way to configure Linux to always treat this monitor as its correct orientation on boot, even before logging into KDE? The monitor itself doesn't have the option to do this at a hardware level.
