Wayland: Display Rotates to Portrait Mode when Certain Apps Open

[Patrick Garraud]

When using a 2 in 1 tablet with auto-rotation (Dell Precision 5530 2 in 1), the screen will frequently incorrectly rotate whenever some apps open. This has been observed with Settings, Videos, Steam, Lollypop and Firefox. Issue still occurs when the screen rotation is locked.

Interestingly Xwayland thinks the screen is portrait:

XWAYLAND2 connected 2160x3840+0+0 (0x3d3) normal (normal left inverted right x axis y axis) 190mm x 340mm

but the BIOS and Xorg think it is landscape:

[ 0.495406] efifb: mode is 3840x2160x32, linelength=15360, pages=1

[ 52.062] (II) modeset(0): Modeline "3840x2160"x60.0 533.25 3840 3888 3920 4000 2160 2163 2168 2222 -hsync -vsync (133.3 kHz eP)

so that makes me think it's just mutter/gnome-shell giving the wrong info to Xwayland and certain apps.

Do you find the same bug in Xorg sessions? Try logging into 'Ubuntu' instead of 'Ubuntu on Wayland'.

The bug doesn't occur in Xorg and the Auto-rotate overall is much faster and more responsive.
