Black screen and blinking cursor on resume with multi-GPU (desktop) setup

Support Graphics & Display

Hello, I’m facing a real head-scratcher with a multi GPU setup, where I can’t resume from sleep if my thunderbolt eGPU was plugged in at all during boot or after.

Basically what I want is to be able to use my iGPU (this is on a desktop, it’s the Intel Alder Lake-S GT1 [UHD Graphics 770] built into my motherboard) to run the desktop etc. then use my dGPU (RTX 3080 Ti) in addition to my eGPU (RTX 3090, plugged in via a Wikingoo mount over TB4) for more demanding applications including games and ML inferernce.

So far it’s working pretty well, I can use prime-run to offload applications onto my dGPU, and I can use CUDA_VISIBLE_DEVICES=1 to restrict applications like llama.cpp to my eGPU. I also really like that kwin and the gang are no longer hogging 2-3GB of my dGPU’s VRAM. To be clear, the DisplayPort cable is plugged into the slot on my motherboard, and I have no other monitors.

But when I try to bring my computer back from suspend (S3 state) I’m stuck with a black screen and a blinking cursor. Switching to TTY1 through 7 it’s the same thing, no consolr or login prompt. Then if I do CTRL+ALT+F2 it’s just a plain black screen.

Here’s my /etc/modprobe.d/nvidia.conf as per the recommendations on the Arch Linux wiki for External GPUs as well as for Nvidia GPUs in general

options nvidia NVreg_PreserveVideoMemoryAllocations=1
options nvidia_drm modeset=1
options nvidia_drm fbdev=1

softdep nvidia pre: thunderbolt
softdep nvidia_drm pre: thunderbolt

Here’s my /etc/mkinitcpio.conf:

MODULES=(thunderbolt)
BINARIES=()
FILES=()

And here’s the relevant line from my /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet udev.log_priority=3 pcie_ports=native pci=assign-busses,hpbussize=0x33,realloc,hpmmiosize=128M,hpmmioprefsize=16G"

The weird thing is, when I boot without my eGPU attached via thunderbolt, I can resume from suspend, but it still displays the black screen with a blinking cursor for a little bit. But it does let me back. So there’s clearly some interference with the eGPU.

The eGPU is such that it’s basically a PCIe backplane with an adapter card to thunderbolt, and the whole thing has its own PSU. Even in suspend I still have a green light on the thunderbolt adapter card, but that’s probably normal.

Let me know if there’s any more relevant detail I can give. Presumably a journalctl would be helpful, but I could use some help with the specific command to provide the most relevant data. I didn’t want to just dump the whole thing.

Sorry if this is already a solved thing, but I just didn’t find any drop-in solutions for my use case. I tried all sorts of kernel params, a clean install, etc. and this is the closest I’ve gotten but the suspend issue is still present. Any help would be greatly appreciated, thanks!

I should also mention I’ve tried with and without thunderbolt.host_reset=0 in the kernel params, as well as with and without the following to no change in the resume/suspend situation:

pcie_link_state=off usbcore.autosuspend=-1 intel_iommu=on no_console_suspend

Hi @substrafe and welcome to the Manjaro Community! :vulcan_salute:

Re: journalctl an example would be journalctl -b -1 | tail -50 - this shows the last 50 entries from the previous boot; adjust as necessary.

It may well also help if you provide the output of inxi -zv8 - this is normally asked for in Support topics. :wink: Note: The output of this command is privacy-filtered.

Hopefully someone with more knowledge of these setups will be able to assist further. :slight_smile:

Thanks for the welcome! I’ve been a long-time lurker but I’ve always appreciated this forum, especially the update threads. Thanks for sharing those logging commands, yeah I hope someone will have some insight. I feel like this can’t be that obscure of a use case, but maybe I’m wrong.

OK so it took a bit more then 50 lines, but here’s what I hope is the relevant part of the journalctl from last boot. Sorry if it’s a bit messy. Pretty sure the AER logs don’t mean anything. Crucially the system seems to suspend but I never see anything about it resuming. It’s like it just cuts off at a certain point.

I wouldn’t call this a full solution (yet at least) but I think I’m getting somewhere. Basically I’m able to soft-disconnect the eGPU then physically unplug it after running these commands:

echo "0000:70:00.0" | sudo tee /sys/bus/pci/drivers/nvidia/unbind 
echo 1 | sudo tee /sys/bus/pci/devices/0000:70:00.0/remove
echo 1 | sudo tee /sys/bus/pci/devices/0000:70:00.1/remove

Then I can suspend and resume properly. Plugging the eGPU back in after resume gets it automatically recognized. Still a bit of a pain, and I have to ensure no processes are running on the eGPU before I want to suspend, but it’s better than r

I tried to be as systematic as possible with troubleshooting, but it devolved into a little bit of this, little bit of that as it often does. But I’ll try to document what I changed at least.

/etc/mkinitcpio.conf now has MODULES=(thunderbolt nvidia nvidia_modeset nvidia_uvm nvidia_drm)

These are the enabled kernel flags:
pcie_ports=native pci=assign-busses,hpbussize=0x33,realloc,hpmmiosize=128M,hpmmioprefsize=16G thunderbolt.host_reset=0

And here’s /etc/modprobe.d/nvidia.conf:

options nvidia_drm modeset=1
options nvidia_drm fbdev=1

softdep nvidia pre: thunderbolt
softdep nvidia_drm pre: nvidia

options nvidia NVreg_DynamicPowerManagement=0

Also I disabled the nvidia-suspend, nvidia-hibernate, and nvidia-resume services because apparently in driver version 595 and above these are no longer needed (see point 10 on the Arch forums’ NVIDIA Tips and Tricks article). Not sure if I had to do that, but keeping them around didn’t make much sense if they weren’t needed.

Like I said it’s still not a perfect solution, and I’d like to think there’s a better solution out there just beyond my reach. But maybe this could be helpful if someone else is in a similar boat.
