CURRENT UBUNTU 8.04 HARDY HERON

Current State

Well, the fan problem took back on 8.04, so i decided to look for a solution for this and future versions. Searching around the net, seeing that no solutions for this problem came from launchpad. The fix came from the kernel mailing list itself, at this thread: http://bugzilla.kernel.org/show_bug.cgi?id=5289

Quoting from there: The issue is that ACPI first tries to read device power state from _PSC method, if this is unsuccessful, it evaluates device state from the power resources, defined for this device. In your DSDT the _PSC is defined with 0x00 value, and never being updated later, so the device state is always reported ON. With this patch the things should work as expected.

I want to give a big THANK YOU! to Konstantin Karasyov for fixing the dsdt file. I was with no time to read that long thread at the gentoo forum to learn how acpi works.

Here is what you have to do to run ubuntu linux from scratch on this laptop:

From the start

Installing Ubuntu 8.04 is just straight forward. It detects your video card, modem and wifi with atheros. I recommend to install the official close source ati driver, and do it from the latest using EnvyNG, anyway, the driver that comes with ubuntu works perfectly.

The first thing is fixing the ""fan bug"". Grab the fixed dsdt.aml file from http://launchpadlibrarian.net/13974391/dsdt.aml or here http://www.wolfspain.net/linux/DSDT.aml.tar.gz

Copy it to /etc/initramfs-tools/ leaving the uppercase up. After that, run sudo update-initramfs -u -k $(uname -r) (or -u -k all to update all your initram kernel files).

Then, edit /boot/grub/menu.lst file and add acpi_no_auto_ssdt to the kernel boot lines. Add it to the #defoptions line to make all the new kernel additions enabled with that too. This tells the kernel to not make a new dsdt file at boot and reads the dsdt file you copied.

Fixed this, let's go for the wifi connection. This laptop uses a wifi enabled by a button not controlled by hardware. Because of this, you get a wifi working with no antenna. You need two things: enable the rfkill=0 option for the ath_pci module from the atheros driver, and then, activate the wifi as it was enabled by pression the button, using a module that one guy (BIG THANK YOU! to Martin Vecera) made for the A1655G fujitsu laptop, that also works on the l1310g.

Be sure to have the build-essentials package installed, and grab the file from http://www.marvec.org/amilo/fsaa1655g.tar.bz2 or from http://www.wolfspain.net/linux/fsaa1655g.tar.gz

untar, compile with make, and then sudo make install. You'll have to do this for every kernel update. (Maybe someone can send it to the kernel team? ). After doing this, make a sudo modprobe fsaa1655g radio=0. The wifi led will turn on. Let's make it permanent:

Edit: /etc/modprobe.d/options

Add:

options fsaa1655g radio=1

options ath_pci rfkill=0

Then: /etc/modules

Add: fsaa1655g

After that, you'll have a laptop with the fan bug at bios resolved, and a wifi fully working. Everything else was set up automatically by ubuntu.

I had no success with the lm-sensors (no sensors detected) and the cpu throttling gave me problems (i remember to made it to work on dapper, but i don't care anymore... caused a delay when changing freqs).

Hope everything helps to the people that have this laptop, or the people from other laptops who suffer from fans being controlled by acpi (hp, ibm...).

This laptop has a great screen, and some people have upgraded the cpu and the memory (the harddisk is easy to change too) so let's take care of this laptop for more time with our favourite O.S. (if only i could change the video card.....)
