1 JohnMcPherson 1 Miscellaneous notes for HP Pavilion laptops
4 JohnMcPherson 2 !!!DV4000 Series (dv4114AP)
3 JohnMcPherson 3 !!X configuration
4 See [i915-xorg.conf]. This machine doesn't support the 1400x1050 widescreen resolution but it looks fine in 1280x800.

6 JohnMcPherson 6 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. It seems that the xorg i810 driver needs to be modified for this to work. There is a modified development version of this driver that may work for you - in Ubuntu Edgy, install the *xserver-xorg-video-intel* driver instead (and configure Xorg to use this instead of the default i810 driver). (Apparently the latest Fedora also includes this alternative driver, if you are running that.)

8 !!Configuring the Touchpad
9 The touchpad does a 'button1' mouse click when you tap it, which is much too easy to do accidentally while typing.

4 JohnMcPherson 11 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).

30 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shipped with xorg in ubuntu breezy doesn't seem to work with this touchpad; this can be fixed by manually installing a newer version of the synaptics driver.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 0.14 works, 0.13 doesn't).
2 JohnMcPherson 31 The changelog for breezy's xorg-driver-synaptics package shows:
32 <verbatim>
33 xorg-driver-synaptics (0.14.3+revertedto+0.13.6-0ubuntu1) breezy; urgency=low
34 * Revert to old upstream version for preview at least, as the new was quite
35 catastrophically broken with ALPS. Fixed some, broke a lot (closes:
36 Ubuntu#14480).
37 </verbatim>
38 Anyway, instructions for installing the newer version from source are [here|http://www.ubuntuforums.org/showthread.php?t=76515].
39 The new driver will move the mouse much more slowly than the normal PS/2 driver, so make sure you set the other options for scroll speeds.
