Andy, James,
After trying Andy's suggestion, and fumbling and guessing my way through a
large number of things, I now have Ubuntu up and running in low graphics
mode.
I think I know what graphics adaptor to tell it to use, but I don't know
what to tell it about my monitor. Looking at the HP tech support web site,
it's not at all clear which monitor was installed on my laptop. Do I just
guess-and-test until something works?
Thanks,
Hal

After the splash Ubuntu screen, I see about four of the login screen

username box.
Ok, sounds like the driver have been switched to either the wrong one or
wrong mode.
Use CTRL-ALT-F1 to get a console. You'll have to login there. Don't worry
that it wont echo the password, that's normal
next type "sudo nano /etc/X11/xorg.conf" without the quotes. You'll be
asked for your password again. Scroll down to where you see the graphic
card idintified. You should see something resembling the following
Section "Device"
Identifier "Generic Video Card"
Driver "nv"
Busid "PCI:1:0:0"
Option "AddARGBVisuals" "True"
Option "AddARGBGLXVisuals" "True"
Option "NoLogo" "True"
EndSection
What does yours list there? Take note more so of the driver here.
Below that will be the monitor and default screnn areas. Might help to
report back what they say as well
At the very worst, where mine says "nv" can be replaced with "vesa" just to
get a working screen. For nvidia cards it's usually "nvidia" for 3d support
or "nv" for 2d acceleration
When making a change use CTRL-O to write back to disk. CTRL-X will exit
back to the prompt at which you can type "sudo reboot" to reboot the system
for changes to take effect for now
Do you recall exactly what you did before things went awry?
I was going to suggest exactly the same thing, but realised you can do
the same thing in a way that may be easier for a new user by running
dpkg-reconfigure.
I.e.:
get a terminal using ctrl-alt-f1
log in as a normal user.
type:
sudo -i
and type your user's password to become root.
then type:
dpkg-reconfigure xserver-xorg
This will start a text mode menu system which lets you reconfigure the
graphics card. If you say yes whenever it asks you to autodetect
something, and choose the selected option the rest of the time, you
should get a working configuration. If not, try setting the driver to
'vesa' instead of (probably) 'nv' when that option comes up.
You need to type:
/etc/init.d/gdm restart
to restart the graphics system (x server) after you've changed the
configuration. You shouldn't need to reboot.
Hi Al
This is where the envy script at the page I pointed to should get your card up
and going with any luck. install the deb package at
http://albertomilone.com/ubuntu/nvidia/scripts/ubuntu/envy_0.9.9-0ubuntu1_all.deb
then go thru Applications -> System Tools -> Envy
that will install it. If it finds a ready installed one it will prompt you to
uninstall it before carrying on
James
