Display corruption in Fedora 4 install -- cannot proceed

rpz · 12-08-2005, 08:48 AM

I am trying to (re)install Fedora Core 4 on my box, but when I boot from the install CD, the display gets all corrupted just after booting the kernel. I am using the TV-out function on the graphics card, since I have no access to an ordinary VGA monitor (it's just a "wardrobe server" anyway...)
. I have tested the boot CD on my laptop and just after the kernel is booted, the graphics mode is switched to another text mode (with blue background IIRC). The behaviour is the same regardless of whether I set the "text" flag in the grub boot prompt. I also tried vga=ask and picked different numbers, at least 1 and 2 worked (with different font sizes), but this does not seem to matter when the kernel is booted and the installation wizard is kicked in. Can I set some failsafe mode flag for the installation wizard program itself somehow? Or is there some way of remote controlling the installation via the network (remember, I don't see what I'm doing so don't expect me to type in anything).

I have also tried the Knoppix CD and it works perfectly with 800x600 (the default mode).

The graphics card is a Radeon 9200 with S-VHS and VGA outputs.

Any help is appreciated.

Oops. Guess I should have read the release notes (http://fedora.redhat.com/docs/release-notes/fc4/).

Quote:

Certain hardware configurations (particularly those with LCD displays) may experience problems while starting the Fedora Core installation program. In these instances, restart the installation, and add the "nofb" option to the boot command line.

This solved my problem. Hope this helps someone....
