Re: Grub 2 EFI blind mode [Solved]

[Richard Collins]

Thanks Tom but the problem wasn't the discs, I've had some success. It's a case of multi problems, I think my PC has a grudge.

 

Problem #1: no keyboard/mouse with 64 bit distros

Reason: IOMMU support was enabled in the BIOS, this was enabled to try and fix #2

 

Problem #2: NVidia driver is unstable on a Grub2+EFI+64bit system

The fix was supposed to be disable the graphics that grub uses. This causes #3

 

Problem 3#: Changing the grub settings I discribed means that you can't see the boot screen - not a feature I'm comfortable with and stops booting if the boot process needs user input.

Solution: ?

Hello all, I need some help. My system has become unbootable.

 

It was working fine with EFI booting until I set the following in /etc/default/grub.conf

GRUB_GFXPAYLOAD_LINUX=text

GRUB_GFXMODE=auto

 

I then ran update-grub2

 

When I reboot grub says:

"error: invalid video mode specification 'text'

"booting in blind mode"

 

the system then hangs indefinatly after a brief flash from the harddrive. It may be waiting for a password for an encrypted volume I have but i wont repond to "S" or "Esc" keypresses

 

I've tried adding set gfxpayload=true|keep|false - none of which work

Ive tried adding set gfxmode=640x480

 

The kubuntu boot cd wont load properly and 12.04 has broken keyboard / mouse support. this is driving me mad!

 

How can I undo the changes I made at the commandline?

Does anyone know a good efi rescue system?

 

I have a MSI 990FXA-GD65 (version E7640AMS V19.9)

The system only has Kubuntu 12.10 installed on ssd with gpt
