Used to work a couple of weeks ago.

No problem from console with concurrent Xorg session running, though:

What is the version of xorg-xserver you're using? What xf86 driver?

[emersion]

DRI3 1.2 adds GetSupportedModifiers, PixmapFromBuffers, and BuffersFromPixmap. We'd need to add fallbacks for these if we want to support 1.0.

What is the version of xorg-xserver you're using? What xf86 driver?

What xf86 driver?

I used xf86-video-modesetting in my testing. Maybe xf86-video-intel doesn't support DRI3 1.2.

[CaptainBloodz]

xf86-video-intel removed, xorg-drivers rebuild, xorg-server rebuild, xorg-server restart.

wayfire now displays fine from terminal.

wlroots-X11-1 main window forever remains grey, i.e. without any display:

[emersion]

Re-opening because this is still an issue with the xf86-video-intel driver.

[jbeich]

Bisected to d79a00bf0208. xf86-video-intel defaults to DRI3 disabled but when enabled the error appends (has 1.0, want 1.2).

xf86-video-intel defaults to DRI3 disabled

It sounds like this bug report is due to a downstream distribution not enabling DRI3?

when enabled the error appends (has 1.0, want 1.2)

Right. See https://github.com/swaywm/wlroots/issues/2586#issuecomment-753031332 for the action needed to fix this.

[emersion]

Can you try https://github.com/swaywm/wlroots/pull/2655?

[jbeich]

0.12.0-254-gb0b9638e showed transparent/black screen but 0.12.0-256-g77e7c0c0 works fine if DRI3 is enabled.

[emersion]

Thanks for testing. What are these hashes? They don't look like wlroots commits.

[jbeich]

What are these hashes? They don't look like wlroots commits.

git describe origin/pull/2655/head output. With only hash: b0b9638e and 77e7c0c0.

[emersion]

Oh, I see
