UHD Graphics 630įlags: bus master, fast devsel, latency 0, IRQ 140, IOMMU group 1 Lspci -v gives this output which seems fine: 00:02.0 VGA compatible controller: Intel Corporation CometLake-S GT2 (rev 03) (prog-if 00 )

The offending line seems to be this: (WW) modeset(0): No outputs definitely connected, trying again. However, as expected, the computer responds normally to SSH access and I can interact with it remotely. Nothing is displayed in the X terminal and regular terminals cannot be accessed with for ex. I get graphics at boot time and in BIOS, but when the system tries to start X, the screen goes blank permanently. It seems that no displays are detected by the graphics chip at all.

I am using Debian testing (Bullseye), XFCE and lightdm. The motherboard is an ASUS Prime B560M-A and the display used is a Sony Bravia KDL-55W905A. I'm trying to build a new media PC, and chose a low-power Intel Core i5 10600T processor, which has an integrated UHD 630 graphics chip.
