Miscellaneous notes for HP Pavilion laptops

-This covers the widescreen LCD and the Svideo-out.
See [i915-xorg.conf]. This machine doesn't support the 1400x1050 widescreen resolution but it looks fine in 1280x800.

+On this machine, <tt>fn + F4</tt> doesn't change to the SVGA or S/Video output, even though those are configured properly in the xorg.conf file.
!!Configuring the Touchpad
The touchpad does a 'button1' mouse click when you tap it, which is much too easy to do accidentally while typing.
-The touchpad isn't supported by the 'synaptics' touchpad driver in xorg, at least with the default kernel (as of 2.6.12).
+The touchpad isn't supported by the 'synaptics' touchpad driver in xorg, at least with the default kernel (as of 2.6.12). It apparently uses the "alps" protocol. This requires both kernel support (in the psmouse.ko driver) and xorg support (provided by the synaptics driver
).

+__Note__: at some stage throughout breezy's life-cycle, the kernel package has broken support for this, and the devices file above shows:

This means that I can't get it to work with with anything other than a plain PS/2 mouse, and these notes don't work any more. Hopefully this is fixed in Ubuntu 6.06 (Dapper).

+The synaptics driver shipped with xorg in ubuntu breezy doesn't seem to work with this touchpad; this
can be fixed by manually installing a newer version of the synaptics driver. (version .14 works, .13 doesn't)

The changelog for breezy's xorg-driver-synaptics package shows:

xorg-driver-synaptics (0.14.3+revertedto+0.13.6-0ubuntu1) breezy; urgency=low
* Revert to old upstream version for preview at least, as the new was quite
