Ubuntu 10.04LTS on hp Envy14

[Simon Bridge]

Hey it works :) well... I want to be able to power off one of the gfx
cards and also disable the touchpad on the fly. The first is doable in
the 2.6.35 kernel (vga_switcheroo) but Ubunutu's kernel messes
everything up ... compiz stops working (loads both intel and radeon
modules - and I found no sign of switcheroo) and the touchpad goes
haywire ... installing the kernel messed up the configuration of the
old, working, one too so I had to purge it.

By default both cards are powered though only the intel is used. (The
live disk only used the ATI - which I could live with). Powering both
shortens the battery life by lots... switcheroo sounds like the ideal
soltion for this and it is reported to work flawlessly in OpenSUSE.

I used to be able to do the second from a script that ran off a
keypress... but that involved setting options in xorg.conf and I'm
guessing there is another way to do that now.

The pad responds to multiple touches out of the box, but the two-finger
zoom thing acts like a scroll-wheel and I don't know how to turn it
off... makes it hard to drag and drop and I can use the edge as a wheel
thanks.

Otherwise it actually goes really well.
The machine itself pretty much lives up to its name even though its
getting on now.

Tried again - works better now: the switcheroo stuff seems to be fine,
need to test the hdmi port on the ati card to see if this is useful.

However - the clickpad now only has one button (button zones are not
differentiated) and the wireless won't go either.

the card is broadcom 4353 ... which went out of the box with the 2.6.32
kernel. On install, there was an error that the proprietary driver
failed to compile. Investigating shows me that it is looking for headers
in the wrong place. I can edit the #include statement in the source, but
would really prefer dpkg or even apt to run the install so there's a
record.
