== Current Issues ==
 * Desktop effects does not work, has issues in Compiz and thus is [[http://wiki.compiz-fusion.org/Hardware/Blacklist|blacklisted]].
 ** Can be circumvented by disabling the blacklisting and using only mplayer/x11 to play videos.

== System Info ==
Hewlett-Packard
HP Compaq 6720s
F.04 (Hardy test machine had F.09)

== Old BIOS versions ==

 * BIOS versions below F.03 are known to give network problems. A workaround is to boot with the kernel option "pci=noacpi" which allows you to download a newer BIOS. See [[https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/151887]]

=== Notes ===

 * wireless needs firmware: install package ''bcm43xx-fwcutter'', but still gives error "MAC suspend failed" (see bug:https://bugs.launchpad.net/ubuntu/+bug/153358)
 ** can be circumvented using ndiswrapper and driver form windows xp; 
   in Hardy ndiswrapper breaks suspend and hibernate
 * mic needs better volume settings: activate recording and turn up channel ''capture'' to 80 %
 * cpu frequency scaling works only by selecting module P4_clockmod explicitly
 * network install in Hardy failed when PC Card services were started
 * Hardy network install needed vga=771 option
