Hey!

I've just jumped to booting via UEFI. Truth be told, I'm booting grub from UEFI, and grub boots my gentoo. It works 8)

Well, 2 things are missing. After grub starts booting the linux kernel, there's nothing to see anymore. I don't see boot messages, and I can't see the TTYs. After X is started, I can login and use my PC normally, but changing to TTY1 or such leaves me with an empty screen. I _can_ still use that TTY, I can login and type commands (which I can verify by switching back to X and look in the process list), but the screen stays empty.

I didn't see anything about that in the docs. Did I miss something? Thanks for any pointers!

I also just upgraded my system and converted to UEFI boot. I had a problem something like this and had to play with the framebuffer settings. I have use nvidia-drivers and used this thread as a guide:

Thanks for the link. It's mostly concerned with X though, which wasn't my problem. I tried a lot with framebuffers and the like, to no dice.

I found the solution from Ubuntu though: https://wiki.ubuntu.com/BootGraphicsArchitecture. The winner is
Code:
gfxpayload=keep
For reference, here are the relevant parts from my /etc/default/grub:

Code:

# The resolution used on graphical terminal.
# Note that you can use only modes which your graphic card supports via VBE.
# You can see them in real GRUB with the command `vbeinfo'.
GRUB_GFXMODE=1280x1024x32

# Set to 'text' to force the Linux kernel to boot in normal text
# mode, 'keep' to preserve the graphics mode set using
# 'GRUB_GFXMODE', 'WIDTHxHEIGHT'['xDEPTH'] to set a particular
# graphics mode, or a sequence of these separated by commas or
# semicolons to try several modes in sequence.
GRUB_GFXPAYLOAD_LINUX=keep


Before I was using 'text' for GFXPAYLOAD, which does not seem to work out with UEFI. Still ok now :)
