Install report Panasonic Let's Note R3

[janne]

Most hardware is detected and set up fine, including network, sound,
USB2.0 ports and the DRI-based
almost-accelerated-if-you-push-it-down-a-steep-cliff i855 graphics
chipset. Laptop mode and cpu throttling works just beautifully out of
the box.

* Synaptics touchpad is detected, and with some manual editing of the X
config, the circular scroll is enabled:

* The ipw2200 wireless device is detected and the correct driver is
loaded, but it causes random kernel lock ups within a few minutes when
you try to use it.

* By default, the special access keys (for things like screen
brightness, volume control and so on) are not recognized. Go here for a
driver that will build cleanly on Ubuntu (hopefully included at some
point in the future?):

http://www.netlab.is.tsukuba.ac.jp/~yokota/archive/pcc_acpi-0.8-hy20040929.tar.gz

The related acpi scripts:

http://www.netlab.is.tsukuba.ac.jp/~yokota/archive/pcc-acpi-utils-20041013.tar.gz

The scripts need to be edited a bit - Ubuntu already handles battery and
ac events, and does not have swsuspend enabled, so this needs to be
removed.

* External monitor output works with a utility called i810switch,
available in Universe (the scripts above are already configured to use
it).

* At this point I have not been able to make suspend to ram work - it
goes to sleep, and when I wake it, I get some response at the hardware
level (the on-light is steady instead of pulsing), but Ubuntu never
wakes up.

* PCMCIA is unknown, but I see no reason it shouldn't work. The modem is
unknown for me as well, and likely to stay that way. Apparently, the SD
card reader is patent/license encumbered and so unlikely to ever work.

* I am a little concerned that the centrino drivers aren't loaded (and
do not seem to be able to either); after all, this is a centrino laptop
and should use it, no?

In all, except for the wireless driver problem and the lack of suspend,
things work fine. I have seen bug reports on the driver issue (or at
least some problem that looks very similar), so I'm hopeful this will
resolve itself at some point.
