Current Issues

Bugs

* Some modules fail to resume after suspend.

Resolved

* Suspend is ok but when I type "echo mem > /sys/power/state" ubuntu shutdown after resume and there is a bug with klaptopdaemon witch doesnt call acpi suspend ! > Resolved

for the irda, a good solution is to set the RESTART_IRDA line to "true" in the /etc/default/acpi-support file :

# Restart Infra Red services on resume - off by default as it crashes some
# machines
RESTART_IRDA=true

(thanx to -PaulSladen)

Hardware details

Notes

Special keys

1. Install the AcerHK module Acer HK (for P1 & P2 buttons)

2. at end of /etc/init.d/bootmisc.sh, add these lines

setkeycodes e071 201 # for P1 button
setkeycodes e072 202 # for P2 button

1. add these lines in $HOME/.xmodmaprc

keycode 169 = XF86Launch0 # P1 button
keycode 171 = XF86Launch1 # P2 button
keycode 160 = XF86AudioMute
keycode 174 = XF86AudioLowerVolume
keycode 176 = XF86AudioRaiseVolume
keycode 178 = XF86WWW
keycode 236 = XF86Mail

SpeedStep

Somes Acer 2012Wlmi processors are dothan, like mine :

$ cat /proc/cpuinfo

Speedstep for centrino works with the standart kernel, but if you want to add 800, 1000 and 1200 Mhz supported by the Dothan follow these steps.

1. patch your kernel with this patch Speedstep Centrino Dothan Tables

2. recompile your kernel, and ... Magic, it works!

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
600000 800000 1000000 1200000 1500000

Before doing that, read the disclaimer for this patch on this site : http://localhost.ruhr.de/~stefan/acerTM292/

• Please file a bug against linux-source-2.6.15 that this patch should be applied -PaulSladen

• Why should I ? this is not a kernel problem but, an ACPI bug of my computer, he is not build for a dothan but for a banias! However, the last series are equiped with a dothan, thus, the acpi tables are written for banias wich support only 600Mhz & 1500Mhz)" -Feeling

InfraRed

• Please file a bug CC'ed to mjg59 with a dump of your PNP tables and dmidecode; there is an option in /etc/default/acpi-support to reload the IRDA modules after unsuspend if it does not crash your machine. -PaulSladen

• Since I run dapper kubuntu, I'm not able to suspend my computer, a bug report is done : https://launchpad.net/distros/ubuntu/+source/kdeutils/+bug/32785" -Feeling

Suspend and Hibernate

kernel side: Works nice since 2.6.14.4. for hibernate (suspend to disk), just add "resume=/dev/hdaX" in your grub or lilo config where hdaX is your swap partition like that:

part of menu.lst:

title           Ubuntu, kernel 2.6.16
root            (hd0,1)
kernel          /boot/vmlinuz-2.6.16 root=/dev/hda2 ro quiet splash resume=/dev/hda3
initrd          /boot/initrd.img-2.6.16
savedefault
boot

However : in kubuntu dapper flight 4 & 5 there is a bug with the klaptopdaemon, when I click "suspend", nothing happend, and the computer fail on shutdown ...

a bug report is running : https://launchpad.net/distros/ubuntu/+source/kdeutils/+bug/32785

The Kernel

For Somes various reason, I always build my own kernel :

• lastest release with bugfixes
• Pentium-M optimisation
• a minimum of useless modules
• Patches for ACPI for my laptop (dothan frequency/voltage tables)

HowToDo ?

• Get the sources http://www.kernel.org

• in /usr/src : tar jcfv linux-2.6.xx.xx.tar.bz2
• ln -s linux-2.6.xx.xx linux
• cd linux
• make menuconfig
• make-kpkg --revision 1 kernel-image --initrd binary (take some times ...)
• dpkg -i linux_image-xx.xx.deb
