Nvidia, compiz, and the white screen (again)

[Ignition22]

Hey guys.

I messed up.

So I updated the kernel without a corresponding nvidia driver. Compiz manager set to start automatically at start-up using gnome "startup programs" gui menu.

Result? Three to four seconds of "everything looks good" before compiz manager starts and changes everything to a white screen.

Fine, I think, I'll just try to redo it. I hit ctrl-alt-F1. for some reason, I do not get a prompt.

This is the only OS I have installed on this computer, so it skips over grub on bootup.

Is there any button press I can use during boot that will get me a prompt?

Basically, how do I get it to re--recognize/install the driver, or, barring that, how do i disable compiz from starting on bootup?


Nvidia drivers were installed following this method:

I've gone over these threads, but nothing has helped:

Yeah, I know, it was a dumb mistake. How can I fix this?

There are several threads on this in the last day or so. Two options -

1. boot into the previous kernel until the new kmod is available
2. install the akmod for your driver. This is the better method as you don't have to worry about kernel updates again. See the thread you followed to install the drivers originally.

My problem is that I cannot boot into a previous kernel. Fedora is the only OS on that computer and so, for some reason, it just skips over the grub menu. Is there anyway I can force it to access the menu or boot to a prompt? Otherwise I can't even get to a prompt to install anything new.

If I installed a second instance of fedora, would I be able to access the grub menu? I really don't want to lose all the customizations I have done.

Press esc as it starts to boot. It will display the menu and select the last kernel that worked, probably the second one.
