Unable to wake external monitor with xrandr

smartding · 2022-03-27 04:31:06

My Environment

I'm using a laptop with an external monitor. The monitor is connected to the laptop via a usb-c to usb-c cable.

The laptop CPU is 11th Gen Intel(R) Core(TM) i7-1165G7, it has a builtin Iris® Xe Graphics.

I'm running the 5.16.16-arch1-1 kernel, with xorg-server 21.1.3-6, and the suckless dwm window manager.

According to xrandr, my external monitor is DP-1 and laptop builtin monitor is eDP-1.

Problem Description

The problem I have is this: I can't wake up the external monitor with xrandr after it's gone to sleep, steps to reproduce:

1. turn off the external monitor with xrandr --output DP-1 --off
1. external monitor says: "no signal, going to sleep"
1. wait a few seconds, until external monitor is actually asleep
1. run xrandr -q, the output is as follows, it looks like external monitor (DP-1) is still alive:

Additional Info

If I try to wake up the external monitor after I turn it off with xrandr --output DP-1 --off, but before it's fully asleep, I can wake it up.

It shouldn't be a hardware problem, because I can wake up the external monitor when using Windows10.

https://wiki.archlinux.org/title/Power_ … utosuspend ?
"usbcore.autosuspend=-1"

nb. that userspace power managers can and will alter that at runtime, so you need to configure it there (as well)

Is this on xf86-video-intel or the modesetting driver?
Does the monitor re-appear when you re-plug it?

ceterum censeo: 3rd link below.

smartding · 2022-03-27 08:04:52

@seth

Adding "usbcore.autosuspend=-1" as kernel parameter doesn't work.
I checked the value at /sys/module/usbcore/parameters/autosuspend, and it's still "-1" after I boot, so I guess no userspace power managers changed the value.

My xorg log at ~/.local/share/xorg/Xorg.0.log says the following, I think I'm using the modesetting driver:

The external monitor doesn't re-appear after I unplug/re-plug it. It only appear after I reboot my laptop.

seth · 2022-03-27 14:26:30

Does it show up when you reload the "evdi" kernel module?
You could try the xf86-video-intel driver (though I don't expect it to be an improvement)

Do you have the configlet that assigns the modesetting driver to the evdi module?
https://wiki.archlinux.org/title/Displa … xx_Devices

Maybe post the entire xorg log (particularily after you lost the display) - oh, and you did make sure that windows fast start is (still) disabled?

smartding · 2022-03-29 12:16:24

@seth

I can't find any kernel module "evdi" from lsmod.

From the wiki page you referenced, it's for DisplayLink devices. My external monitor is LG 27UL850, is it a DisplayLink device?

I've uploaded my xorg log here: https://pastebin.com/raw/ggc7fHez,

I experimented a bit more, I can turn up the external monitor with xrandr --output DP-1 --auto after unplug/re-plug it.

I was under the impression because of

The monitor is connected to the laptop via a usb-c to usb-c cable.

The board maps it it to DP.

It's normal that a new output doesn't become auto-enabled, you could use https://aur.archlinux.org/packages/x-on-resize for that.
Instead of physically reconnecting the display, you could perhaps write the device ("n-m") into /sys/bus/usb/drivers/usb/unbind & /sys/bus/usb/drivers/usb/bind (iff it shows up in lsusb), but first

smartding · 2022-03-29 15:29:12

@seth

windows fast startup is definitely off.

How do I determine the "n-m"?

dmesg says [ 681.686937] usb 3-3.4: Manufacturer: LG Electronics Inc., but the external monitor is still on after running echo 3-3.4 | sudo tee /sys/bus/usb/drivers/usb/unbind

seth · 2022-03-29 15:30:54

Try just "3-3" but you'll also have to echo it into /sys/bus/usb/drivers/usb/bind afterwards ("plug it")

smartding · 2022-03-30 05:45:00

@seth

Physically unplug/re-plug the external monitor, or writing to /sys/bus/usb/drivers/usb/unbind & /sys/bus/usb/drivers/usb/bind is kind of the last resort.

Any idea why I can't wake up the external monitor with xrandr --output DP-1 --auto in the first place? I always can wake up the external monitor if I cold boot or reboot the laptop.

seth · 2022-03-30 06:01:31

Because the connection (very likely) breaks on the USB - if the communication is inhibited there, xrandr can't do anything.
I'd check dmesg/the sysmte journal and compare lsusb from before and after the output is gone.

zacstewart · 2022-03-30 07:17:56

This sounds like the same issue I'm having. I have to unplug/plug my type-c monitor every time it falls asleep.

Are you using one of those Intel integrated iris Xe graphics card?

My external monitor works fine with my older laptop, which has an older graphics card built into i7-8565U CPU.

So I suspect the issue is related to kernel drivers for the new Intel graphics card.

seth · 2022-03-30 12:55:29

My external monitor works fine with my older laptop

Also via usb-c?

Yes, my older laptop connects to the external monitor also via usb-c toi usb-c cable.

It's a Dell xps 13, has nothing but usb-c ports.

The dmesg is as follows, the monitor is detected when I try to wake it up, but nothing is displayed

And there's from journalctl, it's telling the same story as dmesg

Mar 30 21:39:38 archbook kernel: cdc_acm 3-3.4:1.1: ttyACM0: USB ACM device

That's not in the dmesg - when yo boot and the monnitor gets initially detected, is there an ACM device as well?

Edit: https://archlinux.org/packages/communit … odeswitch/ might come in handy …

Sorry, that was the wrong dmesg, I dual boot arch with gentoo, and they have the same issue.

The following is the dmesg from archlinux, it does have the cdc_acm device:

The interesting part is whether the monitor also shows up as an ACM when you boot w/ it or re-plug it.

@seth

Here's the dmesg when I boot the laptop in archlinux, there's a message about cdc_acm device around the time the monitor was detected:

Actually in the two lines above, Fresco Logic is the "not display link" vendor.
Does it re-show when you re-plug the output? (Maybe just post an entire system journal after losing, failing and re-gaining the output w/ the physical cycle)

You also haven't mentioned whether rebinding usb 3-3 gets the job done w/o any cable pluggery.

I've pasted the whole dmesg: https://pastebin.com/raw/jSeyDGBG

It includes the whole process: boot---> turn off external monitor with xrandr ---> try to wake up with xrandr, but fails ---> physically unplug/re-plug external monitor ---> successfully wake up with xrandr

Also, I tried echo 3-3 | sudo tee /sys/bus/usb/drivers/usb/unbind and bind, nothing happened.
