"Input Signal Out of Range"

Asked by Krinen

Every time I try to boot 7.10 from the Install CD, It gets as far as starting to load, before saying "Input Signal out of Range. Please change settings to 1280x1024 60hz."

Problem is, I have NO idea in the least how to alleve this. I've tried the VGA option at the boot menu, to no avail.

Any suggestions?

hello krinen

Can you get to the CLI (Command Line Interface) or are you stuck at a black terminal?

To get to a CLI press:
Ctrl-alt-F1

You S\should see a log in prompt.

If you can get to the CLI you will have to reconfigure X:

sudo dpkg-reconfigure -phigh xserver-xorg

If you have reconfigured your X correctly, then type,

sudo /etc/rc.d/gdm stop
sudo gdm

If you get any errors after trying this.. Please repost along with the errors here..

Hello

Have you tried to start ubuntu is safe graphics mode? To do so insert the desktop CD and boot from it and choose "Start Ubuntu in safe graphics mode". If this didn't work, try following Bhavani Shankar instructions, or just use the alternate CD which should work . Installing using the alternate CD is not a hard process and all the steps are clearly explained. Here is a screencast that shows you the installation process. http://screencasts.ubuntu.com/MoS2007/10_Installing_Ubuntu_Part_2

Okay. So I'm finally IN ubuntu, which is a plus. But I can't change the resolution from 800x600, because it buggers up again. The most I can get out of is 1024x760. But even then it tries to die.

You can try to change video resolution...
- first try to dynamically change screen resolution plese the press CTR + ALT + "+" and/or CTRL + ALT + "-"
- Try to restart the graphic layer press CTR + ALT + BACKSPACE

Reconfiguring your xserver-xorg may help you.

Please open a Terminal from the menu Applications->Accessories->Terminal and type:

To make a backup copy of your actual /etc/X11/xorg.conf type:

cd /etc/X11
sudo cp xorg.conf xorg.conf.bak

give your user password when requested, you don't see nothing when you type it, then press enter.

Then try to reconfigure your xserver-xorg

sudo dpkg-reconfigure xserver-xorg

answer to the simply questions, select multiple more than one screen resolutions when asked, then restart the pc.

If something goes wrong you can restore the saved copy of your old configuration, open a terminal or login to a virtual terminal by pressing ctrl+alt+F2 and type:

cd /etc/X11
sudo cp xorg.conf.bak xorg.conf

and restart the pc, type:

sudo reboot

Hope this helps
