10.0.38 display issue

[plinej]

Everything boots up fine but for some reason my display isn't the preferred 1920x1080.

Code: Select all

wlr-randr --output eDP-1 --mode 1920x1080@40.036999 Hz --pos 0,0 --transform normal --scale 1.25

The 1.25 that it defaults to makes my display 25% larger and actually makes it 1536x864. When I try to change the scale to 1.00 it will either make large black bars on the bottom and right side of screen taking up 25% of my screen or it will correctly adjust 1920x1080 at 1.00 scale but that same part of the screen will just flicker. Sometimes the screen will freeze when using the Wayland video wizard tool as well. I can't figure out why it defaults to 1.25 scale instead of 1.00. I am using the amdgpu module if that makes a difference.

wlr-randr output:

dwl is patched so it automatically chooses the scaling factor that matches your screen DPI.

The scaling factor = (width in pixels / (width in mm / 25.4)) / 96, and it's rounded down to 1, 1.25, 1.5 or 2.

In your case, it's (1920 / (340 / 25.4)) / 96 = 1.49, which is <1.5, therefore the chosen scaling factor is 1.25.

Flickering and crashes are indeed issues that will hopefully get fixed before the stable 10.0.0 release. At the moment, I don't have a fix.

The weird thing is that the modified remastered version of 10.0.24 that I posted actually displays correctly 1920x1080 at 1.00 scale.

[dimkr]

There is a possibility that 10.0.24 was built before this feature was added

Moving the dwl-kiosk executable from 10.0.24 over to 10.0.38 seems to have resolved my issue...

[dimkr]

I added 10.0.x development builds with X.Org, at least until for now. Ideally, I'd like to get the two Wayland flavors polished and stable enough so I can drop this third X.Org flavor before the first stable release.

Yes, I'm currently running the 10.0.42 with Xorg. Everything seems to be working fine. Thank you!
