External monitors not detected unless connected at boot.
I have been using arch for about a year now. Until about a week ago (not sure exact of when this started) my setup was working perfectly. Recently I started running into an issue where my laptop (Lenovo P1 Gen 2) only detects my two external monitors (one connected via HDMI the other via USB-C) if they are both connected at boot. If I try to disconnect after boot and reconnect, my machine cant seem to detect them.
I am very confused and would really appreciate any help. Here is the output of Xrandr after both connected (after boot).

I have recently run pacman -Syu but other than that I have not done much system maintenance since original install.

Re: External monitors not detected unless connected at boot.
The extra outputs will be wired to the nvidia chip, you running on the intel one and reverse prime only implicitly triggered when the outputs are active on the nvidia GPU when X11 starts.
Explicitly set the output provider source, https://wiki.archlinux.org/title/PRIME#Reverse_PRIME

Re: External monitors not detected unless connected at boot.
Thank you sir! This worked perfectly. But I must ask, any idea why this had been working perfectly until just recently? I am still pretty confused on that point.

Re: External monitors not detected unless connected at boot.
Check your pacman log - either the X11 server had unconditionally activated the redirection or some DM/session startup script did.
I was quite frankly not aware of any such implicit behavior (and would not rely on such magic either)
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Re: External monitors not detected unless connected at boot.
So actually this is not solved. It just turns out that now, when I boot with the monitors connected I can connect and disconnect no problem. But if I boot without the monitors connected I run into issues.
Here is the output of some commands used when follwing the reverse prime directions:
➜ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630] (rev 02)
01:00.0 VGA compatible controller: NVIDIA Corporation TU117GLM [Quadro T2000 Mobile / Max-Q] (rev a1)Based on that I set my /etc/X11/xorg.conf to the following
Section "ServerLayout"
Identifier "layout"
Screen 0 "intel"
Inactive "nvidia"
Option "AllowNVIDIAGPUScreens"
EndSection
Section "Device"
Identifier "nvidia"
Driver "nvidia"
EndSection
Section "Screen"
Identifier "nvidia"
Device "nvidia"
EndSection
Section "Device"
Identifier "intel"
Driver "modesetting"
BusID "PCI:0:2:0"
EndSection
Section "Screen"
Identifier "intel"
Device "intel"
EndSectionThe command xrandr --listproviders now gives me
➜ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x42 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 1 associated providers: 1 name:modesetting
Provider 1: id: 0xca cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 4 associated providers: 1 name:modesettingNotably both have a name of modesetting and I am not sure what to do here.

Re: External monitors not detected unless connected at boot.
Please post the output of
lspci -k
pacman -Qs 'nvidia|linux'
uname -aand your xorg log, https://wiki.archlinux.org/title/Xorg#General
Something went wrong about your nvidia driver installation.
Edit: perhaps a race condition and you need https://wiki.archlinux.org/title/NVIDIA … de_setting or - if you have the modules in the initramfs - https://wiki.archlinux.org/title/NVIDIA#pacman_hook

Re: External monitors not detected unless connected at boot.
Well, you certainly had it configured.
If you're using sddm see https://wiki.archlinux.org/title/Xrandr#Configuration and run "xrandr --setprovideroutputsource NVIDIA-G0 modesetting" in the Xsetup script
