I just bought a new MSI Z790 motherboard with an Intel i9 and 32 GB of memory.
It has one HDMI built in and one antique NVidia for which Debian drivers are no longer available. "inxi -G" says 12Device-1 Intel Raptor Lake-S GT1 [UHD Graphics 770] 12driver i915 12v kernel 12Device-2 NVIDIA GF108 [GeForce GT 630] 12driver nouveau 12v kernel 12Display 12server X.Org 12v 1.21.1.7 12with Xwayland 12v 22.1.9 12driver 12X 12loaded modesetting 12unloaded fbdev,vesa 12dri swrast 12gpu i915,nouveau 12resolution 121 1920x1200~60Hz 122 1920x1200~60Hz 12API OpenGL 12v 4.5 Mesa 22.3.6 12renderer llvmpipe (LLVM 15.0.6 256 bits) I have two displays on the NVidia GF108, an Envision L22W898 (and old TV) 1600x900, and an old HP vs17 (1280x1024). When I booted with only these two displays connected, everything works correctly. If I boot with the HDMI device powered up, the GDM3 login screen doesn't appear on the primary display. Rather it's kind of a dull big- pixel dirty pool-table green without my user name or a box for the password. Maybe it's displayed at 10000x10000 on a 1600x900 screen. If I type in my password blind, KDE starts up OK. After having started once with the HDMI plugged in, the GDM3 screen doesn't return to normal even with the HDMI device unplugged or powered off but plugged in. Is there a GDM3 setting that can repair this? The KDE System Settings => Display and Monitor => Display Configuration configures the HDMI device correctly if it's connected and powered on when I boot. If I power it on after booting, it doesn't come. And there's no "scan for more devices" button in the system settings widget. Is there a way to turn it on after I boot, maybe in a Gnome widget? And gkrellm only shows 16 of the 32 threads; the other 16 are presumably. Is there a version of gkrellm, newer than the Debian 12.5 distro, that allows to set up multiple columns, or has a scroll bar?
