can't set virtual console resolution

[mro]

when EFI booting my x250 Thinkpad into 14.3-RELEASE.

I have the resolution during boot via /boot/loader.conf

exec="gop set 2" # during boot, 800x600x32
kern.vt.color.0.rgb="#303000"
kern.vt.color.15.rgb="#00f000"
kern.vt.fb.default_mode="640x480x16" # has no effect

But not on the virtual terminals afterwards.

I know https://forums.freebsd.org/threads/drm-user-defined-mode-not-supported.96680/#post-710068, read
vt() and

$ cat /usr/local/etc/pkg/repos/kmods.conf

Mind there is no connector.

How can I get consistent 800x600 on all virtual consoles?

Try setting efi_max_resolution="800x600" in /boot/loader.conf, see if that works better for you.

           efi_max_resolution

           vbe_max_resolution
                     Specify the maximum desired resolution for the EFI or VBE
                     framebuffer console.  The following values are accepted:

                     Value           Resolution
                     480p            640x480
                     720p            1280x720
                     1080p           1920x1080
                     1440p           2560x1440
                     2160p           3840x2160
                     4k              3840x2160
                     5k              5120x2880
                     WidthxHeight    WidthxHeight

loader.conf(5)

added

$ fgrep efi_ /boot/loader.conf
efi_max_resolution="800x600"

rebooted, no effect.

 

[SirDice]

kern.vt.fb.default_mode="640x480x16" # has no effect

That one is wrong by the way, you only give it the resolution, not the number of color bits. So kern.vt.fb.default_mode="640x480"

thanks SirDice, changed to

$ fgrep 800x600 /boot/loader.conf
exec="gop set 2" # during boot, 800x600x32
# kern.vt.fb.default_mode="800x600x32"
kern.vt.fb.default_mode="800x600"
efi_max_resolution="800x600"

reboot, still no effect.
