Hello,
I Installed a new video card (same model is running on another computer using openSUSE Leap 15.4 with same proprietary drivers just fine). Since then the computer boots to a blank screen.
What this computer used as video output before you installed this card? Where is video connected?
Using legacy grub2 to boot (menu displayed fine, first lines of initrd
What is "legacy grub2"?
are displayed, then screen goes blank). Tried booting using nomodesset, uninstalled plymouth, rebuilt initrd, reinstalled bootloader no changes. I can start the X-Server via SSH, then screens work. I can also switch
I am not sure I understand what "screens work" means. You get output on connected monitor? How exactly are you starting X-Server (full commands)?
to other ttys then, showing the console. Probably a serial console would work also. ;-)
video card is a Nvidia GeForce GTX 1080 Ti nvidia drivers (nvidia-video-G06-525.116.04-lp154.8.1.x86_64) load fine, dmesg (last thing I did was start the X server) can be found here: https://www.swabian.net/extern/opensuse/dmesg_blankscreen.txt
Normally kernel is using framebuffer. This shows VGA as console device which implies that your device is not considered framebuffer-capable. Can you show cat /proc/ioports cat /proc/iomem
current cmdline: BOOT_IMAGE=/boot/vmlinuz-5.14.21-150400.24.63-default root=UUID=406791e3-4103-4da5-8235-aa35ed5be74c nosplash resume=/dev/disk/by-id/scsi-36c81f660cfd00400232bc7c603abcd39-part4 splash=nosplash debug showopts elevator=cfq mitigations=auto nomodeset
what do I miss? only significant difference to other pc (despite of other hardware (but identical video card)) is, that that one uses efi not legacy boot.
This sounds like something between the system BIOS and NVIDIA BIOS.
