[Bug 577460] Re: Large screen-noise on Compaq 6820s with ATI Mobility Radeon X1350

[Guenael Amieux]

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
