Your monitor does not seems to support that resolution... very strange, can you try on sway if it gets the right resolution?

Also, on IRC you mentioned wlr-randr --custom-mode doesn't work can you attach the stderr of dwl -d (in that session try to set the custom mode)

EDIT: just in case, run dwl directly from the tty

sway cannot get the right also..

idk how to get the stderr of dwl

sevz17 commented 9 months ago

So... here are two problems:

wlroots somehow does not recognize all modes of you monitor
dwl can not set a custom mode

To get the stderr of a program you need to redirect it to a file which is done with 2> path/to/file, e.g dwl 2> dwl.log, this will create a file named dwl.log in your current directory, attach that file 1> or almost always used as > is to redirect the stdout

EDIT: please use the latest commit to get the logs, -d was added recently

Thank you for your help.

I tried ways and find that add my resolution to grub's GFXMODE and this time wlr-randr custom-mode works well.

I also successfully get stderr from dwl -d, but this time it looks good, so I don't paste it here.

sevz17 commented 9 months ago

Ah, then your driver/monitor did not expose all the modes.
