UEFI hangs

Hello,
 
I followed this guide for setting up UEFI: http://www.funtoo.org/UEFI_Install_Guide

 

After I select an option from GRUB the screen just goes black. I have SSH server on for testing and the system never goes up.

 

I have tried with both the debian binary kernel and a custom kernel. I also haven't ran an emerge -auDN world (maybe this is my problem), as I'd imagine it shouldn't matter if Xorg radeon drivers are installed to get to a shell.

 

Here is the config for the custom kernel I tried.

 

  Reveal hidden contents

 

 

Here is my make.conf

 

  Reveal hidden contents

 

 

And my grub.cfg

 

  Reveal hidden contents

 

 

Any ideas? My video card is an R9 270x if that helps :).

 

Thanks.

Thanks for your reply. nomodeset didn't work for me. Your advice was helpful and I made sure my settings were right, so thank you for that :).

 

Unfortunately, it still didn't work. So I decided to try something different.

 

I ended up finding a fix! I'm now able to boot in correctly. I believe this is a fix for someone that's exhausted all possible kernel trials. I'm assuming this is a funtoo grub packaging problem or something was wrong with my grub.cfg. It's just weird because grub was loading fine, that is why I assumed kernel error.

 

Here is what I did to fix it:

  1. emerge --unmerge grub
  2. Added a local overlay, something like /usr/local/portage is good.
  3. Added gentoo's version of grub to the overlay. It was also a newer version than funtoo's.
  4. emerge -va grub
  5. grub-install --target=x86_64-efi --efi-directory=/boot /dev/sda
  6. grub2-mkconfig -o /boot/grub/grub.cfg
  7. Restarted and was able to get into my system.

If anyone has any idea why the funtoo grub didn't work for me, let me know.

I had a similar problem a few months ago, since you are able to see the grub menu and select an option, that's working fine, and since you don't seem to be getting to init, I don't think the @world upgrade is relevant, have you tried booting with the nomodeset flag on the kernel command line?

 

I didn't look at your kernel config but my problem was in the video drivers, In the framebuffer ones, I activated the framebuffer for efi, and my video card, also the generic one, they didn't play nice all at boot, and after some search i found out, I pretty much just wanted the xorg driver for my video card, so I disabled the kernel ones, this might be your case.

Good you solved your problem, I think this is a bug in Funtoo, you should report it, I did my instalation of grub kinda like you, and usually update my configs manually(grub-mkconfig desn't do what I want), and  I didn't use the funtoo boot scripts, so I can't confirm this.(Or maybe after all, it might be solved after a @world upgrade)

Hello Guys,

 

I just bought a laptop, and am trying to get UEFI to boot correctly. I keep hanging in a black screen, and to be quite honest, would like to  keep away from overlaying anything outside the "boot-updater" way.

 

I'm going to try to just use legacy booting for now, but will update if I have any success in the future with UEFI booting.

 

Edit : I think this bug might have something to do with it. I'll use the overlay method, once this but is fixed however, I'll use the proper funtoo method. :)

 

Edit 2: I can confirm using the gentoo grub worked for me as well. I just had to add the initrd line to my grub.conf, which was missing. Once I have a graphical windows manager, I'll reference the full line just to be clear. Thanks!
