Display is garbled

[romanus]

I installed fc3 this afternoon and everythign would be fine if I could get the display to work. I have seen a fix in here and would like to apply it, but how do I boot in a mode I can see the screen? I lose the screen when fc gets to the log-in page.

Thanks for any help.

Please help us to understand further...
From my understanding in your context, I could base on two common scenarios, pick one out of two OR... give us a better explanation.


Is your scenario like this?
1) I can see a graphical user interface screen for me to key in my username and password, however, after doing so, i was only shown with one terminal console box.

OR

Is your scenario like this?
2) I was shown a text-based screen from the beginning, after logging-in, i thought i would see a interface, but im stuck inside this console, help!

Actually neither,

I see a grphical startup right up until the point of the login screen and then the screen goes dark except for a band of random color down the middle vertically, like the video fried. This is an old presario 5000t with a viewsonic pf790.

I had the same problem I read about here on graphic installation where the screen draw properly so I abandoned the graphic installer and went for the text based one.


Thanks for the help

I am having the same exact problem with FC2 and FC3 on a Dell D800 Laptop. I see the post and startup text fine. During the install, I had a vertical garbled line appear on the screen. I could still read most of the display, so I continued the install. After rebooting, when the logon screen appears, the screen is completely garbled. I know it's not the hardware, since I just wiped out an XP install and everything was working fine. I ran Knoppix on it, and everything seemed to work ok. Does anyone have any ideas? I'm a newbie, so I'm really lost on how to fix this.

Thanks in advance,

No guarentees - but something to try:
It sounds like the display device is not capable of handling the default screen resolution used by the installer.
When you boot from the install disk, you are given a chanch to enter some commands before the install actually begins;
at that point enter

lowres

This should let you use the gui installer. (it specifies that the resolution should be 640x480)
I believe that during the install there is an option to define the display device; start with a resolution of 640x480

Please look at the first thread in this forum; it is a "sticky" one posted by DogOne. It contains a list of options that can be entered at the start of an install

Hi,
I installed the Core 3 for 64-Bit Processors in graphic mode without problems. After restart, fedora starts and boot but after the message "Rechnername localhost, localdomain, einstellen: [ok]" the screen become garbage. The screen looks like the frequenz or resolution doesn't fit. And I see the mousecourser but I can't move it. I think my screen is not the problem because the max. resolution is 1600x1200 pixel.

thanks
Andreas

I would hit 'a' on the Grub screen, and append

3

to the kernel commandline. This will stop X starting.

Edit /etc/X11/xorg.conf and navigate to

Section "Device"

in there, comment out the existing Driver line, and replace it with

Driver "vesa"

Save the file and run

telinit 5

to allow X to (try to!) start.

I found the file and the Section "Device" but Driver "vesa" is already there.

Section "Device"
Identifier "Videocard0"
Driver "vesa"
VendorName "Videocard vendor"
BoardName "VESA driver (generic)"

Under the section "Screen" are the Modes "800x600" "640x480"
