[solved] low screen resolution when booting with efi stub

I've just switch to boot my machine with efi stub, before this I used grub.

Everything works except the screen resolution is really low during boot, which looks like 640x480.
The screen resolution becomes full HD after xorg server is started.

I used to set the resolution during boot with /etc/default/grub like this:

GRUB_GFXMODE=1024x768x32,auto
GRUB_GFXPAYLOAD_LINUX=keep

But now, without grub, I don't know how to set the resolution.

I'm running linux-lts kernel with nvidia-lts driver.

Disabling the CSM (compatibility support mode) and setting boot mode to "UEFI only" fixed the issue.

Interesting...
