I want to put one monitor (L, HDMI) on the onboard card (the one provided by the i5) and two more (M, DVI; and R, DP) on a graphics card (GTX 970). The card works as well as it ever did, and its two work fine. The onboard one is rotated. It is connected, but when I run "startx" it retains the sideways text and doesn't show the X desktop. The hardware's not disabled in the BIOS. How should I proceed?
I have Debian 12.9 (Bookworm), xorg something or other (not Wayland), and XFCE 4.18.
