description |
The scenario is two identical 4K-HDR@60Hz DP1.2 monitors plugged into their own TB3 docks plugged into two different TB4 ports on my laptop, and a closed laptop lid (eDP off)
The expected behavior is for both my monitors to enumerate on boot, with mirrored kernel consoles to appear on boot, or as drm initializes, and then for gdm to present a login screen on one of the two monitors as part of an extended desktop across both screens side-by-side.
What happens is that one of the monitors remains blank on boot, even after drm has initialized devices, and then as gdm loads, the opposite monitor comes to life, and the one that showed drm output during boot goes blank. Blank is off, not a lit black screen. The one that is off when gdm is loaded (on previously during boot) is actually where gdm is attempting to display the login prompt. The one that is now on is just lit with a solid black background, which is normal for the second monitor on a desktop extended across both screens. I am familiar with the login, so without seeing the actual login prompt, I can just login as if I could see it on the blank screen, and wayland loads up. Unfortunately even as wayland takes over and applies my display settings, there is no change and the primary display is still off.
I see my desktop wallpaper and icon bar, and can right-click on the desktop and launch the Display Settings, which confirms that wayland thinks both displays are lit. To workaround the issue, and to make the primary display active, I just open display 1 settings and toggle the refresh from 60Hz to 30Hz, and then back to my desired 60Hz, and the screen that was off lights up. Both monitors are now active in 4K@60Hz, like the intended boot settings.
Inspecting xrandr, wayland_info and drm_info shows that drm_info does not align with the other two outputs. I have attached the full outputs as xrandr.txt, wayland.txt and drm.txt respectively.
The drm_info shows the preferred resolutions are correct, but for CRTC 1 (CRTC ID 167) it show the mode @30.00Hz, even though the monitor is running at @60Hz.

The exerpts from xrandr and wayland_info report the correct, running 60Hz on both monitors.

I am looking hard at i915/xe/drm as the culprit, especially given the conflicting output from drm_info after I toggle the monitors into the correct working configuration manually.
I have another laptop (XPS 13 9380 with TB3 ports) where the monitors and docks work properly (expected behavior) so it does look to be isolated to how drm is working in this setup.

Updated (6/17). The scenario is two identical 4K-HDR@60Hz DP1.2 monitors, one plugged into a TB3 dock, plugged into one TB4 port, and the second plugged into a DP-Alt-Mode dock on a 2nd TB4 port on my laptop, with a closed laptop lid (eDP off)
The expected behavior is for both my monitors to enumerate on boot, with mirrored kernel consoles to appear on boot, or after drm correctly initializes during boot, and then for gdm to present a login screen on one of the two monitors as part of an extended desktop across both screens side-by-side.
Since the end monitors are DP1.2, they are limited to HBR2, simplifying the expected protocol configuration on either TB3 or TB4 ports, as each 4K@60Hz HDR monitor will use 4x5.4Gbps lanes (21.6Gbps) to deliver the required 16Gbps using TB3 or TB4.
It works perfectly, in the same configuration on my Dell XPS 9380, using two Alpin Ridge TB3/JHL6540 ports.
On my Lenovo X1 Yoga G6 using Tiger Lake TB4 ports, one monitor remains off during the boot process, and then they switch, and the opposite monitor remains off during the gdm3/mutter/wayland startup.
The workaround is to toggle the display refresh (switching from 60Hz, to 30Hz (monitor wakes up), then back to 60Hz). (I log in blindly as the gdm3 prompt is on the screen that is off, and then right click to "Display Settings" once logged in)
This results in my functioning extended desktop across both screens @HDR-4K-60Hz.
Even in the final working state, there are obvious issues I can see. The first is the drm_info reports that one of the monitors is still running at 30Hz, which is not the case.

The second is gnome shell messages, I assume are from mutter, which repeat periodically, but are shown here from the journal log captured between starting up with one screen off, and fixing it by toggling the refresh as described above.

Inspecting xrandr, wayland_info and drm_info shows that drm_info does not align with the other two outputs. I have attached the full outputs as xrandr.txt, wayland.txt and drm.txt respectively.
I am trying to figure out how to get more debug from these errors, as it looks like drm is making an error as to how the port and monitors line up, if I was to just guess.

description |
Updated (6/17/24). The scenario is two identical 4K-HDR@60Hz DP1.2 monitors, one plugged into a TB3 dock, plugged into one TB4 port, and the second plugged into a DP-Alt-Mode dock on a 2nd TB4 port on my laptop, with a closed laptop lid (eDP off)
The expected behavior is for both my monitors to enumerate on boot, with mirrored kernel consoles to appear on boot, or after drm correctly initializes during boot, and then for gdm to present a login screen on one of the two monitors as part of an extended desktop across both screens side-by-side.
Since the end monitors are DP1.2, they are limited to HBR2, simplifying the expected protocol configuration on either TB3 or TB4 ports, as each 4K@60Hz HDR monitor will use 4x5.4Gbps lanes (21.6Gbps) to deliver the required 16Gbps using TB3 or TB4.
It works perfectly, in the same configuration on my Dell XPS 9380, using two Alpin Ridge TB3/JHL6540 ports.
On my Lenovo X1 Yoga G6 using Tiger Lake TB4 ports, one monitor remains off during the boot process, and then they switch, and the opposite monitor remains off during the gdm3/mutter/wayland startup.
The workaround is to toggle the display refresh (switching from 60Hz, to 30Hz (monitor wakes up), then back to 60Hz). (I log in blindly as the gdm3 prompt is on the screen that is off, and then right click to "Display Settings" once logged in)
This results in my functioning extended desktop across both screens @HDR-4K-60Hz.
Even in the final working state, there are obvious issues I can see. The first is the drm_info reports that one of the monitors is still running at 30Hz, which is not the case.

Updated (6/17/24). The scenario is two identical 4K-HDR@60Hz DP1.2 monitors, one plugged into a TB3 dock, plugged into one TB4 port, and the second plugged into a DP-Alt-Mode dock on a 2nd TB4 port on my laptop, with a closed laptop lid (eDP off)
The expected behavior is for both my monitors to enumerate on boot, with mirrored kernel consoles to appear on boot, or after drm correctly initializes during boot, and then for gdm to present a login screen on one of the two monitors as part of an extended desktop across both screens side-by-side.
Since the end monitors are DP1.2, they are limited to HBR2, simplifying the expected protocol configuration on either TB3 or TB4 ports, as each 4K@60Hz HDR monitor will use 4x5.4Gbps lanes (21.6Gbps) to deliver the required 16Gbps using TB3 or TB4.
It works perfectly, in the same configuration on my Dell XPS 9380 (WhiskeyLake-U GT2 [UHD Graphics 620]) using two Alpine Ridge TB3/JHL6540 ports.
On my Lenovo X1 Yoga G6 (TigerLake GT2 [Iris Xe Graphics]) using Tiger Lake LP TB4 ports, one monitor remains off during the boot process, and then they switch, and the opposite monitor remains off during the gdm3/mutter/wayland startup. (Used to file this bug report)
The workaround is to toggle the display refresh (switching from 60Hz, to 30Hz (monitor wakes up), then back to 60Hz). (I log in blindly as the gdm3 prompt is on the screen that is off, and then right click to "Display Settings" once logged in)
This results in my functioning extended desktop across both screens @HDR-4K-60Hz.
Even in the final working state, there are obvious issues I can see. The first is the drm_info reports that one of the monitors is still running at 30Hz, which is not the case.

The second is gnome shell messages, I assume are from mutter, which repeat periodically, but are shown here from the journal log captured between starting up with one screen off, and fixing it by toggling the refresh as described above.

Inspecting xrandr, wayland_info and drm_info shows that drm_info does not align with the other two outputs. I have attached the full outputs as xrandr.txt, wayland.txt and drm.txt respectively.
I am trying to figure out how to get more debug from these errors, as it looks like drm is making an error as to how the port and monitors line up, if I was to just guess.

There are a lot of unused ports to possibly confuse DRM.

I am looking hard at i915/xe/drm as the culprit, especially given the conflicting output from drm_info after I toggle the monitors into the correct working configuration manually.
Any help appreciated
