Linux on a Fujitsu U810, P1620, T1010 - Ubuntu 10.10 Maverick

Last week I upgraded to latest Ubuntu, Maverick 10.10.

Everything seems fine; Ireally suggest anyone of you with a u810 to upgraded asap.

- external monitor: works great

- suspend/resume: works great

- touchscreen: uhm ... the touch driver failed working. As pointed by nerd65536 and mifa (thanks for the fast fix), just with a small modification everything is working again.


So please find here the latest version of the driver !!

Also, following the suggestions from nerd65536, this version fixes the driver problem on suspend/restart, and README instructions are improved.

Linux on a U810 - ubuntu install latest kernel

To solve some issues with external monitor, I was suggested by

https://bugs.freedesktop.org/show_bug.cgi?id=26833

to install latest kernel. So I did, here are the steps:

1) download *386, *all packages from
http://kernel.ubuntu.com/~kernel-ppa/mainline/

linux-headers-2.6.36-020636rc2_2.6.36-020636rc2.201008230905_all.deb
linux-headers-2.6.36-020636rc2-generic_2.6.36-020636rc2.201008230905_i386.deb
linux-image-2.6.36-020636rc2-generic_2.6.36-020636rc2.201008230905_i386.deb



2) install
$ sudo dpkg -i *.deb


=> done, not the new kernel appears in the grub menu !



3) note to main: to de-install:
If you would like to uninstall a mainline kernel anyway, first use:

* dpkg -l | grep "linux\-[a-z]*\-"

to find the exact name of the kernel packages you want to uninstall, and then do:

* sudo apt-get remove KERNEL_PACKAGES_TO_REMOVE

Remember that several packages belong to one kernel version: common headers, architecture specific headers and the architecture specific image.

Linux on a fujitsu U810 - Lucid setup

As a reminder for anyone upgrading to lucid:

when I booted into X after upgrading to ubuntu lucid, I missed the minimize/maximize/close buttons at the top-right of every window; for some reason, they are not there.

In order to make these buttons reappear, proceed as follows: (info taken from
http://www.baptiste-wicht.com/2010/05/ubuntu-lucid-lynx-buttons-right/)

- start gconf-editor (type gconf-editor at the terminal)

- go to : apps > metacity > general. You’ll see here a key named button_layout with the default value of “close,minimize,maximize:”. To put the buttons like in
the other versions, you just have to edit this value to

:minimize,maximize,close

And then all your windows will have the normal button order at the right of the window title bar.

- if you want to include the window menu, you can change the value to :

menu:minimize,maximize,close

Linux on a Fujitsu U810, U820 - keyboard lights

short story: it's working !! - keep reading

Some readers of this blog where still missing this feature, so I engaged the daunting task of finding some time and energy to solve this issue. After 5 hours of googling, reading documentation about acpi, linux kernel, reading c code for the linux kernel drivers, googling for ubuntu file repository source files, ... I found the solution, which is very easy:

=> keyboard lights can be easily controlled by accessing the sysfs <=

Since the sysfs is root-only, I have created a small c program, with automatic compile and install, that makes keyboard-lights accessible for any user.

Installation

1 download the fujitsu-kbdlights-0.1.0.tar.gz to any directory in your computer


2 decompress the package (it will create another directory, fujitsu-kbdlights-0.1.0/)
tar zxvf fujitsu-kbdlights-0.1.0.tar.gz


3 compile and install
cd fujitsu-kbdlights-0.1.0
make
sudo make install


4 and in a command shell, you can type

fujitsu_kbdlights on

fujitsu_kbdlights off

fujitsu_kbdlights toggle

fujitsu_kbdlights


5 if you want, you can bind any of the previous commands to a hot-key using any keyboard setup utility

Enjoy typing at night !!
