Why do I get an "out of range" error during Ubuntu 10.10 install?

Prevent Out Of range Error

How this error happens?

You should concentrate on graphic card settings during installation. This error is irrespective of the version of ubuntu you are using. When the preset resolution is more than that of the recommended one, out of range error occurs.


How can we bypass this error?

Pay close attention to the video card settings during installation. Set the resolution to 1024x768 during installation.

Is that possible to cure out of range errors after installation?

yes, you can cure this problem after installation, by pressing Ctrl-Alt-Numpad- and/or Ctrl+Alt+Numpad+ repeatedly; this will keep changing resolutions in an attempt to find one that works. You will have to wait about 2-3 seconds between each press. If you find a resolution that works, post back on how to make it permanent and/or how to get a suitable refresh rate at which ever resolution you like.

Usually, this error is related to the refresh rate being out of range of your monitor.

Try with a different monitor or some more ideas here... http://www.hotubuntunews.com/blog_03.shtml

Thanks.  I can't make any changes though.  Once I choose the boot device it loads for a moment and then goes to the out of range screen.  Once its been up and running for a while I tried ctrl, alt, + or - to no avail.  

@veedar, forgot to mention that.  I tried it with a different monitor.  One that supports a ginormous resolution to no avail.

The problem is not the resolution, its the frequency.  Your monitors likely can't cope with the 70-75 hz used for installation.  Press "F4" at the boot splash screen and select "safe graphic mode".

@I see some different options but nothing regarding "safe graphic mode".

You must be installing the 64 bit version.  Press F6 to open the other options menu.  Close the menu window that opens, we just want to add a bit of text to the line at the bottom of the screen - press TAB to do this.  Press the spacebar once and enter the following text "–xforcevesa", and press enter.  This will force the installer into safe graphic mode.

It's 32bit. I will try these fixes in the morning and repost.

I press F6 then I get the language options.  I press escape, F6 again then escape.  This brings up a line of text for boot options.  Do I type "--xforcevesa" after the -- that's already there?  I've typed it this way and "xforcevesa" after and I still get the out of range error.

No dice.  I still get the out of range screen.  There are two - at the end of my txt.  Should I be deleting these?  I haven't but just checking.

You mean the dashes?  Leave them.  Make sure you add a space after the dashes.

You could also try this option

text

This should drop you to a text based installer.

I'm under time constraints to get this done.  That being said I've installed Ubuntu 9 then I'll upgrade to 10.10.  I appreciate your time.  I've learned a few things so thanks again!

Some people report success by pressing F6 and changing the line

file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash --

to

file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz nomodeset --

I will try that if this issue comes up again.  Hopefully that won't be the case.  Take care.

An update to the post.  Ubuntu 9.10 installed and ran fine.  When I upgraded the OS to Ubuntu 10.x I begin getting the same out of range errors.
