2010 Note: This document is fairly old. Many of the issues that
I needed to solve below now work fine with, for example, a generic Ubuntu
install. Yea for progress! So obviously make sure that things aren't
working before trying the fixes below. On the other hand, the volume
and screen brightness hotkeys stopped working with Ubuntu Hardy. See
below for the fix.
Light, fast, durable.
Usually you only get to choose one. The Panasonic Toughbook Y5 gives
you all three, with a decent size screen to boot. I love this notebook.
It's superlight (almost to the point of feeling flimsy) but it's able
to take serious abuse, as the Panasonic Toughbooks are known for.
Not only that, but you can pour water on the keyboard, and it drains
out the sides. And yes, I tested this out immediately upon receiving
The only (minor) complaints I have are a lack of bluetooth, and the
fact that they claim 8-9 hours of battery life when you only get just
over 4 hours. And 4 hours is pretty damn respectable, it's just not
even close to advertised. Also, the sound is pretty bad. I don't mind
that the builtin speakers are weak, but for some reason the headphone
jack isn't very loud either. Otherwise this laptop kicks ass.
Robert Thau mentions that he's able to get 8 hours on a new battery
with Debian, and DVD/modem powered off through bios with half-dim LCD,
and that it should be possible to get over 6 hours with normal behavior.
Also, regarding bluetooth, there is now a US version which has Bluetooth,
see the bottom for how to find one.
After getting some great advice from Bernard Moret who also has
page for the Y5, I decided to eschew my normal Debian installation
choice to try out Ubuntu.
Let me add to the list of ass-kicking, Ubuntu is also amazing. It's
by far the best linux install experience I've had, and it's on a
bizzare Japanese import laptop. I like Debian, but they can't keep pace.
In the end, almost everything worked.
First here's the machine specs, courtesy dynamism:
Ubuntu Linux on the Panasonic Y5
I used an Ubuntu 7.04 Beta DVD. To boot from the DVD drive you need
to go into the BIOS settings and turn the drive to always on:
BIOS (F2 after boot) -> Menu "Main" -> CD/DVD Drive Power: ON
After that it's a piece of cake, everything works with a quick change
for video. The touchpad is a wheelpad, which means that circular
motion does scrolling, and that works as well. I have not tested the
modem, nor do I care.

Video basically works.
It used to be that you needed to use the intel driver instead of the
810/915 driver with the 915resolution package (to get 1400x1050).
With the intel driver currently supplied with Ubuntu, this does not
seem to be the case.
If you have problems with the intel driver, you can change to i810:
Simply edit /etc/X11/xorg.conf as root and change:
||LCD Video - (see below)
||Ethernet / Wireless. See below. (wlan switch works)
||DVD R/W. See below
||Sound (ALSA/OSS?). See below
||SD Card Reader
||Keyboard / Touchpad
||Hotkey support (volume/screen brightness)
||Sleep to RAM (suspend)
||Sleep to Disk (hibernate)
||Lid event (ACPI) - turns off LCD, can easily be set in control panels
||CPU Frequency scaling - 2GHz/1.5GHz (see panel applet)
Bernard uses XFree86, but I found that Xorg worked fine for me.
If you have the same problem he mentions about a stray line being
screwed up in X after sleeping the computer, then update the driver
(by installing "xlibs-static-dev" and "xserver-xorg-video-intel").
Robert Thau reports that the external monitor works with xorg.conf
changes (at least in "presentation mode" - where the external display
is a clone of the LCD). Edit the xorg.conf:
Add the following to the 'Section "Device"' for the graphics controller:
Option "MonitorLayout" "CRT+LFP,None"
Option "Clone" "yes"
And make a new 'Section "Monitor"' that is a copy of the generic/default
monitor with the Identifier changed to "External Monitor"
Caveat: The external display must be plugged in when the X server starts,
and it may not be scaled to the full screen, depending on your monitor's
First off, check and make sure your default alsa mixer master
volume isn't set to zero. Furthermore,
sometimes ALSA dies after waking up, but OSS still works.
Evidently the solution to this is to make sure that ALSA is loaded
as modules (snd_hda_intel, snd_hda_codec, etc..) and then make
sure the hibernation script unloads/reloads the ALSA sound modules
on sleep/wakeup. Thanks to Robert Thau for the suggestion.
Supposedly the microphone works if you upgrade your ALSA version:
I used OSS at first. Hibernate would sometimes kill sound, but
it seems that doing a suspend and waking back up will restore sound.
I upgraded to Ubuntu 7.10 and the ALSA that comes with it seems to work.
2010 Note: ALSA needs you to set your default card properly:
% asoundconf list
Names of available sound cards:
% asoundconf set-default-card Intel
The wireless works fine, but sometimes the NetworkManager (the menu
of wireless networks) stops working, particularly after suspend or
hibernate events. I've found a few ways to restart it, but the
foolproof method seems to be to restart the dbus:
This will probably force a few things to reload, but it shouldn't do harm.
Can only be put to sleep on boot, and once woken up can't be put to
sleep again. According to Dylan Schwilk
this can be fixed on the Y7 with Ubuntu Gutsy with:
echo foo > /sys/devices/platform/bay.0/eject
The DVD uses the Intel ICH7 chipset, so you need to:
# modprobe piix
Doing that got me from 2MB/s to 8MB/s (using "hdparm -t /dev/scd0")
You need to install a bunch of packages to watch DVDs:
# echo "deb http://medibuntu.sos-sts.com/repo/ feisty free non-free" >> /etc/apt/sources.list
# wget -q http://medibuntu.sos-sts.com/repo/medibuntu-key.gpg -O- | apt-key add -
# apt ins libdvdcss2 libdvdnav4 libdvdread3 w32codecs
# apt rem totem-gstreamer
# apt ins totem-xine
# apt ins gmplayer
I think that's all of them. Loading xine-ui as some pages suggest
only caused problems. totem-gstreamer doesn't do DVD. totem-xine
was supposed to fix that, but I can only get it to work with mplayer.
For gmplayer, you need to specify the 'x11' driver with the -vo
option. For some reason, zoom isn't on by default, so add -zoom.
The volume is awfully low, so I increase it with the 'volume' audio
filter, and I set my default language to english. The final command
line looks like this:
% gmplayer -vo x11 -zoom -af volume=20:0 -alang en dvd://
Then you can set this to automatically run for all video DVDs by
changing this in the menu:
System -> Preferences -> Removable Drives and Media -> Multimedia
I was also having problems with mplayer crashing
MPlayer interrupted by signal 11 in module: decode_video
it helped if I turned up the RTC max freq: (As root):
% echo 1024 > /proc/sys/dev/rtc/max-user-freq
Alternatively, you can add this line to sysctl.conf:
to make the changes permanent. Running as root seems to help considerably as well.
I also noticed that if I had framedropping set to 'hard' then mplayer would
immediately crash. Using framedropping 'enabled' instead fixed the problem.
I'm also trying to recompile mplayer to see if I can file a proper bug report.
If you have problems with the DVD player (or any video player) dying
if it starts in full-screen mode, then you likely have a
video installation problem.
Hotkey support disappeared with Ubuntu Hardy. This is because the Panasonic
hotkey driver (pcc_acpi) was not updated to work with newer kernels (since 2.6.23).
This is discussed in Ubuntu bug 222324
If your hotkeys don't work, first see if you just need to load the module:
# modprobe pcc_acpi
If that doesn't work, you need to patch and compile the module (fairly simple):
There are still some weirdness:
- Get pcc_acpi module from http://www.da-cha.jp/letsnote
- Apply the following patch
- Get hotkeys and power tars from http://www.da-cha.jp/letsnote
- Untar above into /etc/acpi
If hotkeys untars into a hotkey directory, then move the files
into /etc/acpi, and move the events/ files into /etc/acpi/events
A few places will import this from Japan:
Most importantly: Mute/unmute is only for the speakers, not
for the headphone jack. So you may find that suddenly the speakers stop
working but the headphones work. Check and make sure the *FnF4* mute is off!
It seems that the hotkeys are handled in two places, one that shows the
on-screen icons (such as the volume changing), and one that does the change
Brightness ends up adjusted twice - I commented it out of the %dispatch
hash in hotkey.pl since I couldn't figure out where the other adjustment
was happening and it was adjusting the brightness by too much for each
I had to change 'mixer_mode' in hotkey.pl to be 0 so that it
would actually change volume for me.
Function keys are firstly the F1-F12 keys, you need to press the Fn
key to get the hotkeys to work. I haven't figured out how to swap this,
but would like to as I rarely use the F1-F12 keys. I tried creating a
hotkey-setup that used setkeycodes but it didn't actually create the
events that change the volume, so I gave up.
Evidently there's a US version that comes with bluetooth, and you can
get it from the last three retailers.
There's also a Y7 that was just released,
but I don't see anything compelling about the Y7 over the Y5, except
for the 160G HD which I would love to have. And sadly it's the same
price. Makes me wish I'd waited three weeks.
