 Posted: Mon Apr 01, 2013 5:07 pm Post subject: GRUB2 Boot causes loss of signal to monitor |
 |
|
I have a Radeon HD 7770 on a UEFI system running Gentoo. When I boot from GRUB's menu entry, I get the loading message and the screen turns black with no signal received. When I hit 'c' to get to the GRUB2 command line, I can boot perfectly with the following commands:
| Code: |
insmod efi_gop
set root=(hd0,gpt2)
linux /kernel-3.6.11-gentoo root=/dev/sda5
boot
|
And this is my grub.cfg:
| Code: |

# from /etc/grub.d and settings from /etc/default/grub

I have been messing around with my kernel configuration in order to get the proper graphics modules for my Radeon HD 7770. Recently, I had to boot with nomodeset because I would hang at "Waiting for uevents to be processed" . I fixed that problem but I am left with the problem above. Here is my .config for my kernel configuration in case I have a problem with the graphics driver modules: http://labibij.hulk.osd.wednet.edu/files/CONFIG |
