--- Comment #17 from Alois Schlögl alois.schloegl@gmail.com --- so far I've not been able to fix it. I submitted this bug report to debian https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1007832
I compiled vulkan-loader and vulkan-tools from source, but this did not change anything. I the course of investigating the issue, I came across these issues #175, #249, and #446 at https://github.com/KhronosGroup/Vulkan-Tools/issues?q=cuda
I noticed also that unlike in Debian10, on Debian11, that the framebuffer is assigned to the first gpu. This is shown as "logical name: /dev/fb0" when running
# lshw -C display *-display description: VGA compatible controller product: GP102 [GeForce GTX 1080 Ti] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:05:00.0 logical name: /dev/fb0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom fb configuration: depth=32 driver=nvidia latency=0 mode=1024x768 visual=truecolor xres=1024 yres=768 resources: iomemory:27f0-27ef iomemory:27f0-27ef irq:27 memory:c4000000-c4ffffff memory:27fe0000000-27fefffffff memory:27ff0000000-27ff1ffffff ioport:b000(size=128) memory:c5000000-c507ffff
On Debian10, this is not the case. That is currently the most promising lead, but I do not have a solution yet.
