External display goes black after suspend or log in

Support Graphics & Display

Hello everyone,

My secondary display (HDMI or USB-C) works fine, but after a suspend, sleep or whatever, when I log in again, display goes black. It is still connected and detected, but black. Turn off & on screen doesn’t do anything. The only solution is to unplug and plug cable a couple of times and then goes on again normally. Do you know how to solve this issue? I’m on a Lenovo ThinkPad X1 Carbon Gen 11 (Manjaro 6.4 XFCE).

A workaround I found is to use xrandr to turn off & on DP-1, something like: xrandr --output DP-1 --off && sleep 5 && xrandr --output DP-1 --auto --above eDP-1 (or with --mode 1920x1200) but then resolution 1920x1200 is not recognized by monitor anymore, and turns on with a shitty resolution. I then created a script to add such resolution but didn’t work, and screen went black again:

cvt 1920 1200
xrandr --newmode “1920x1200_60.00"  193.25  1920 2056 2256 2592  1200 1203 1209 1245 -hsync +vsync
xrandr --addmode DP-1 “1920x1200_60.00”

Any idea?

Here a few outputs that may be useful:

Hello @sakinyu :wink:

What I suspect is that the display port connection is not waking up from power save mode. So when you wake up, a signal is sent to the monitor that it should be active again, but apparently your monitor doesn’t understand the request or ignores it. This then results in an existing connection, but the screen remains black.

If I were you, I would look for the menu items “eco”, “signal” or “compatibility” in the monitor settings and test them.

Thanks @megavolt. I’ll check. Weird thing, I’m pretty sure the monitor worked well before upgrading Kernel 6.1 or 5.15 to 6.4; and had no troubles with my previous laptop (Dell XPS) also on Manjaro. So I suspect something changed when I upgraded Kernel, maybe on this request you mention. I cannot go back to previous kernel because then I have screen flickering problems unfortunately.

4

BTW, I tested all settings, and I don’t think it is a problem with the monitor. Anyone has a workaround to this problem?

I remember there was problem with another Lenovo Laptop. One of a friend, on the forum or it was mine, can’t say exactly. Anyway, the problem was that the HDMI connection stays powered off when you suspend/hibernate and then wake it up.

Linux also power off these connections just like any usb ports when in battery mode.

You could check:

grep . /sys/class/drm/card[0-9]-*/power/control /sys/class/drm/card[0-9]-*/{status,enabled,dpms}

If power/control is set to auto then overwrite it temporary with on.

sudo bash -c 'echo on > /sys/class/drm/card1-DP-1/power/control'

Now the connection should not be powered off, means: It doesn’t turn off the power.

Maybe also disable dpms: Display Power Management Signaling - ArchWiki

Set this and test a suspend/wakeup. If that works, then I believe it must be the issue with BC/AC mode of the laptop. So:

You start the laptop, Monitor connected: Works in BC/AC :white_check_mark:
Switch to BC mode: HDMI still works :white_check_mark:
Re-Plugin the cable: No :x:
Wakeup after suspend: No :x:
Reason: While in Battery mode, it will not power on again the connection.
Solution: Disable power saving.

You are right, turning power/control on seems to work. I’ll check all the other tests you suggest (AC/BC, etc). I’ll let you know how it goes.

Cheers

@megavolt is there a way to make this change permanent?

Also, I checked the link for the dpms, but the script they show seems to be for the main screen. Do you know how to turn off dpms only for DP-1?
