I solved the issue on my HP6820s, thank to several posts here and
elsewhere on the web :
- press F8 at the beginning of the Ubuntu 10.10 install process
- type F6 and select "nomodeset"
- install Ubuntu normally, the screen will work normally
- open a terminal and type sudo gedit /boot/grub/grub.cfg
- look for the following lines :
### BEGIN /etc/grub.d/10_linux ###
menuentry 'Ubuntu, with Linux 2.6.35-22-generic' --class ubuntu --class
gnu-linux --class gnu --class os {
recordfail
insmod part_msdos
insmod ext2
set root='(hd0,msdos5)'
search --no-floppy --fs-uuid --set 0be7aa27-ffe0-42d2-9d53-fd7e2c595509
linux /boot/vmlinuz-2.6.35-22-generic
root=UUID=0be7aa27-ffe0-42d2-9d53-fd7e2c595509 ro quiet splash
initrd /boot/initrd.img-2.6.35-22-generic
}
- change this line :
from : linux /boot/vmlinuz-2.6.35-22-generic
root=UUID=0be7aa27-ffe0-42d2-9d53-fd7e2c595509 ro quiet splash
to : linux /boot/vmlinuz-2.6.35-22-generic
root=UUID=0be7aa27-ffe0-42d2-9d53-fd7e2c595509 ro nomodeset quiet splash
- save the file.
- reboot, everything works fine.
I hope I did not omit any step !
Best regards,
Guénaël
