Greetings, all. I'm fairly exhausted from searching on this issue for the past day and haven't made much headway. I'll spare everyone the long version and jump to a few bulleted observations:



Dell Studio 1555 (Laptop), Intel 15.6" LCD at 1366x768 Native Resolution.
Intel 4500 Integrated Graphics Card
Initially did an upgrade from 9.04 (7 hour download!) but have since backed up /home and performed a fresh install.
LCD will not display anything after GRUB, but backlight stays on.
Only will display to external monitor through VGA port.
Had no problems with 9.04. Played with Fedora 11 installations, as well. It appears to me that I only have issues with the kernel version is 2.6.29 and above.
Cannot boot to X in LiveCD of Ubuntu 9.10. (CAN boot to X in 9.04 LiveCD)
When viewing Display configuration from the external monitor, both VGA1 and LVDS1 appear as the same monitor on Identification (both go to external LCD) even though the configurations are different.

I appreciate in help in advance. I'll be happy to provide any information to help troubleshoot.

I may have the solution for you.

In booting parameters add the following parameteres: "nomodeset --xdriver=intel" without quotes.
In Installation/Live CD you can press F6, ESC and type the desired parameters, as shown above.

In an installed system (run a live cd to do this)
You can edit your booting parameters in /boot/grub/grub.cfg
This is a menu entry in grub.cfg:
menuentry "Ubuntu, Linux 2.6.31-14-generic" {
recordfail=1
if [ -n ${have_grubenv} ]; then save_env recordfail; fi
set quiet=1
insmod ext2
set root=(hd0,1)
search --no-floppy --fs-uuid --set f2fbc756-0f16-434b-90b1-9a740040b6e3
linux /boot/vmlinuz-2.6.31-14-generic root=UUID=f2fbc756-0f16-434b-90b1-9a740040b6e3 ro quiet splash
initrd /boot/initrd.img-2.6.31-14-generic
}

Add like this: linux /boot/vmlinuz-2.6.31-14-generic nomodeset root=UUID=f2fbc756-0f16-434b-90b1-9a740040b6e3 ro quiet splash

OR/AND you need to edit at /etc/X11/xorg.conf
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
like this: Driver "intel"

Remember that the files /boot/grub/grub.cfg and /etc/X11/xorg.conf are owned by root, and other users have no permission to edit these files, in addtion they are read only. To workaround this you can chmod/chown then to your user. I prefer "chown 777 /path/to/file". Dont forget to put back the permissions, if you dont, this could be used to harm you, since now anyone can edit this files and make your system stop working. (its difficult, but possible)

This should solve your problem, and also in fedora 11.

I'm having problems finding boot parameters to get my nvidia geforce 6 series pci-express card past the first install screen, or past the login screen after using the alternate install cd. This happens with 9.04 as well as 9.10.
Can you guide me on what boot parameters to enter to get into the livecd part?
