Intel 845G/Intel 64: preupgrade and Fedora 11 Install DVD both display a black screen
 
Does anyone have any idea how I can convince Anaconda to ignore the detected video driver and use instead the VESA driver? The "detected" driver is, in fact, the correct driver for my hardware, but that driver does not correctly read the monitor's properties. As a result an incorrect refresh rate/size combination is used, and the monitor goes black. This makes it quite difficult to use the system.

If I could access a command prompt, I could, presumably, force the correct values by setting /etc/X11/xorg.conf, but
  1. The Fedora team, in it's infinite wisdom, has disabled the tty access, so <ctrl>-<alt>-<F2> seems to have no effect when the "black screen" is displayed. (On my other F11 instalations, the <ctl>-<alt>-<f2>, etc., keys do work after log-on.)
  2. Anaconda/update ignores a working xorg.conf file, choosing instead to rely on the "automatic" X-server detection -- which, as I note, fails for my hardware.
By the way, and FYI, on my laptop, with F11 installed on a USB drive, I've noticed that tty1, instead of tty7, is now used for a startx -- :0. tty8, 9, and 10 are still used for :1, :2 and :3

<edit>
O.K., I'm now up-and-running on the problem system. The solution was to borrow one of my wife's (smaller) monitors and boot with that. Now I only get a "black screen" 'till the system does the startx so I don't see the really clever "Fedora" symbol filling with light. (Well, I guess I can live without that, eh?)

Still, for people with a monitor like mine (A Sceptre 22" LCD) who don't have an understanding wife (or other friend) with a monitor that talks to the Intel driver, there may be people complaining about a "black screen of death."

Have you tried using the safe graphics option on the install DVD? (Option 2)

I have to add the following options to the grub/boot command to get the installers to display, or even get fedora to display after installing it (even though xorg.conf says the driver is vesa).

xdriver=vesa nomodeset

Thanks for the tip: Perhaps I'll try that when I upgrade to Fedora 12.
