When a display is set to be turned off at startup, all displays fail to properly modeset when using an NVIDIA GPU with the proprietary NVIDIA driver. This results in all monitors being turned off and the desktop being unusable.

Turning off the display after starting niri does not cause this, though it weirdly does cause both displays to modeset even if the mode hasn't changed on the other display.

System Information

• niri version: niri 26.04 (8ed0da4)

• Distro: Arch Linux x86_64

• GPU: NVIDIA GeForce RTX 3070 Ti

• CPU: AMD Ryzen 7 5700X

Uhh can you replicate this on sway and cosmic-comp

Uhh can you replicate this on sway and cosmic-comp

On Sway, the second monitor correctly turns off upon starting the session. In Cosmic, it doesn't result in a black screen but the second monitor doesn't actually turn off, instead just showing whatever was last visible on the tty. It properly disabled when I initially set the config.

[Sempyos]

Uh could you test in some other compositors such as gnome or kde,

[coatlessali]

I have now tested it in both GNOME and Plasma. When I log in, the monitor correctly turns off without anything happening on my primary monitor. Niri is thus far the only compositor I've found that exhibits this behavior.

[Sempyos]

uh when it breaks on niri could you provide the output of journalctl -e --user-unit niri --no-pager

This patch for libglvnd helped me fix launching niri.

[Sempyos]

idk, I feel that would make this mainly a nvidia/gl issue and not niri

unsure though

[Sempyos]

..?

[FurryMileon]

..?

The crashes are caused by this library. The problem is that the library has already fixed it, but Niri hasn’t updated it yet.

[Sempyos]

Can't really say that without any logs, as it's an assumption
