Need Help Booting Computer Through "nomodeset"

Asked by jr

Hello,

I'm new to linux, and I'm dealing with this bug: https://bugs.launchpad.net/ubuntu/+s...er/+bug/593489

In short, my monitor goes blank when I try to start Ubuntu 10.04. I was able to install it through the "nomodeset" option, but now I can't turn the computer on without the monitor going blank. I'm only able to access the computer by going through a livecd and clicking that option (that is what I am doing right now.)

What I need to do is make this nomodeset option permanent, for the harddrive.

However, the instructions I've seen for how to fix this problem all involve going into GRUB and editing a file, and I am having a lot of trouble getting into GRUB. I have tried pressing escape when I first turn on the computer and the BIOS window it takes me to is not GRUB, but instead the Dell one, the same one it had when Windows XP was previously installed.

I've been trying various methods of editing this file through the command terminal inside this livecd, but I keep failing. I could really use some help.

To boot your installed Ubuntu... by adding temporary the modeset to the installed kernel launch parameter

Please press shift at boot of the installed Ubuntu and edit the grub row (see keys grub instructions in that window)

look for the row with "quiet splash" at the end and add the nomodeset paramater

then boot with ctrl+x

Then to made this parameter permanent...

Referring to https://wiki.ubuntu.com/Grub2 and to this page https://wiki.ubuntu.com/Grub2#grub (/etc/default/grub)

You need to change the file /etc/default/grub from Applications→Accessories→Terminal type:

gksudo gedit /etc/default/grub

Change the row:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Then save and close then still using terminal type:

sudo update-grub

Then reboot your pc.

I really appreciate it. It took me some patience because it really didn't want to go into grub, but after several tries and tapping the shift key repeatedly, it eventually went into GRUB.

Thank you so much!
