Heho,

I know this thread is old, but I have exact the same problem here.

I started from an Ubuntu Persistent LiveCD 11.10 (USB) and reach the "Installer Boot Menu"

A normal boot won't work, because my monitor has the "out of range" message after I choose anything in the boot menu.

So I hit the TAB-Key to see the boot params:


/casper/vmlinuz noprompt cdrom-detect/try-usb=true file=/cdrom/preseed/ubuntu.seed boot-casper persistent initrd=/casper/initrd.lz splash --I changed it to

/casper/vmlinuz noprompt cdrom-detect/try-usb=true file=/cdrom/preseed/ubuntu.seed boot-casper persistent initrd=/casper/initrd.lz vga=791 --as well to

/casper/vmlinuz noprompt cdrom-detect/try-usb=true file=/cdrom/preseed/ubuntu.seed boot-casper persistent initrd=/casper/initrd.lz xforcevesa --but it doesn't solves my problem.

Any othr ideas?

thanks in advance
Michael

Hi and welcome, I have moved your post to it's own thread. No need to revive a two year old thread. :)

You are talking about

/casper/vmlinuz noprompt cdrom-detect/try-usb=true file=/cdrom/preseed/ubuntu.seed boot-casper persistent initrd=/casper/initrd.lz nomodeset --
Doesn't work ... :(

A lot of logs, but than a reboot ...

Michael,

Here is what I do- Mostly on Servers where they only have VGA Graphics or for older Desktops... add the vga switch as


vga=268
Which is VESA, but not recognized in Linux. It displays an error message, but offers instead a text menu with display options in VESA VGA modes. Select a basic option (will be type a letter from the menu, then <Enter>).

Hope this info helps.

What video chipset do you have?
