External displays not waking up after suspend (Hyprland, NVIDIA)
Good day everyone,
I'm new to Arch Linux forums but have been using the operating system for a year or two now. I'm setting a fresh install on my laptop and encountered an issue where after waking up from suspend, the external displays don't wake up (internal one works fine) and even after I power cycle the displays they say "no signal."
My specs are as follows:

...
[ 0.326084] ACPI: PM: (supports S0 S4 S5)
...But cat /sys/power/mem_sleep shows:
[s2idle]... which seems contradictory. I believe s2idle is supported due to my laptop being quite new and wakeup time after systemctl suspend to be quite fast (only a few seconds).
<QuickTangent>
I haven't been able to get hibernate working:
Call to Hibernate failed: Not enough suitable swap space for hibernation available on compatible block devices and file systems</QuickTangent>
When I put my laptop to sleep either by systemctl suspend or closing the lid, it behaves normally, turning off lights and all displays. However, upon waking back up my external displays stay off as described above.
Interestingly, xrandr outputs the same thing as before. Even hyprctl monitors lists everything normally:

I can open apps on and move apps to/from external displays just fine. But they stay black.
hyprctl dispatch dpms on returns ok and powers on the external displays but they don't display anything besides indicating that there is a signal. The backlight turns on but the display stays black.
xrandr --output HDMI-A-1 --auto and xrandr --output DP-3 --auto have no effect.
It's worth noting that (as far as I know) my external displays are hardwired to the dGPU. I suspected that the dGPU wasn't waking up somehow but nvidia-smi still shows P8 and I can even do a prime-run glxgears and it works fine.
Following various forum posts, I tried unplugging and replugging the displays to no avail. In fact it's worse now as xrandr says this:
...
HDMI-A-1 connected 0x0+5120+0 (normal left inverted right x axis y axis) 530mm x 300mm
0x0 0.00*+
DP-3 connected 0x0+2560+0 (normal left inverted right x axis y axis) 600mm x 340mm
0x0 0.00*+hyprctl monitors appears to be unchanged.
hyprctl dispatch dpms on returns ok but has no effect now.
xrandr --output DP-3 --auto does nothing but ... HDMI-A-1 ... outputs this:
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 21 (RRSetCrtcConfig)
Value in failed request: 0x1400
Serial number of failed request: 36
Current serial number in output stream: 36Also, I can't move my mouse cursor off the internal display now. Interestingly, using keyboard navigation I can still use apps on external displays as before.
I hope I've provided enough information. I can always provide more, too. Much appreciate any help for this problem -
Thanks,

Re: External displays not waking up after suspend (Hyprland, NVIDIA)
Update:
After even more browsing I came across this post:
seth wrote:
Is this S3 ("deep") or s2idle?
https://wiki.archlinux.org/title/Power_ … end_methodDo the systems still respond to an ICMP request (ping) and/or can you ssh into them?
Is this also an issue when only booting the multi-user.target (in doubt along "nomodeset")?
Can you reboot the system from the "black screen" using the https://wiki.archlinux.org/title/Keyboa … el_(SysRq) (nb. that you've to explicitly enable that first!)Since it's both nvidia, do you https://wiki.archlinux.org/title/NVIDIA … er_suspend ?
I have a ping LA.PT.OP.IP running on another computer and it stops while the laptop is suspended (both after lid close and after systemctl suspend).
Also, I should have tested this earlier but restarting Hyprland fixes the issue. Might anyone know a way to resume sleep without restarting Hyprland? Thanks.

I can't say my knowledge is quite enough to understand what all of it means though. :sweat_face:
Also, my fans seem to sometimes spin up when I do a suspend, although not always.

Re: External displays not waking up after suspend (Hyprland, NVIDIA)
Did you setup the suspension hooks as detailed in https://wiki.archlinux.org/title/NVIDIA … er_suspend ? These are somewhat of a requirement for proper wakeup from suspend on nvidia.

Re: External displays not waking up after suspend (Hyprland, NVIDIA)
Hello,
Thanks for the reply. That was actually something I had just seen late yesterday night and was planning to try in the morning 
I will look into that and report back.

Re: External displays not waking up after suspend (Hyprland, NVIDIA)
Hello,
It works! Thank you so much :sweat_face:
For documentation purposes, I did:
$ sudo vim /etc/modprobe.d/nvidia.conf
# add: options nvidia NVreg_PreserveVideoMemoryAllocations=1
$ sudo mkinitcpio -P
$ sudo systemctl enable nvidia-suspend.service nvidia-hibernate.service
$ rebootOffline
