no bootsplash/console with gutsy on a hp/compaq 6715s

[Jonas Meurer]

Hello,

I just installed ubuntu gutsy on a hp/compaq 6715s laptop. i used the
alternative cd, as the graphical installer didn't work. After 
installation the bootscreen was simply black, and i needed to change to
tty1 manually to see a login prompt at the end of the bootprocess.

the Xserver didn't work either. I had to install the fglrx drivers and
run some configuration script which updated /etc/X11/xorg.conf.
Afterwards gdm started without any issues, but after a restart the
virtual console was broken instead.

and that's my current situation:

soon after grub in the boot process everything on the screen disappears,
and i see a black screen until gdm starts the Xserver.
if i try to change to a virtual console like tty1 afterwards, i just see
a black screen, exactly like during boot process.

i already tried to use vga=785 in /boot/grub/menu.lst and set resolution
to 600x480 in /etc/usplash.conf.

i didn't try to turn of usplash completely yet, but as the console is
even unaccessible after boot i cannot believe that this is a usplash
issue.

is this a known issue with the 6715s, and do you know a fix for it?

maybe it's some problem with framebuffer mode and the proprietary
ati x driver?
i remember that proprietary nvidia x drivers don't work with the
nvidiafb kernel driver. maybe similar issues exist for the ati fglrx
drivers?

please cc me, as i'm not subscribed to the list.

thanks in advance,
 jonas
