Suspend to RAM on Debian Etch and IBM Thinkpad X31

Seems like my machine (Thinkpad X31 with ATI Radeon Mobility M6 LY) locks up when resuming from suspend-to-RAM unless I comment out the line

VbeToolPost yes

in /etc/hibernate/ram.conf. Regular hibernation to disk works fine out of the box though.

Bug filed on the Debian hibernate package.

CPU frequency scaling in Debian 4.0 Etch

Apparently there is a more "correct" way to enable CPU frequency scaling in Debian 4.0 GNU/Linux Etch than I described in an older post.

For future reference:

$ echo speedstep_centrino >> /etc/modules
$ echo cpufreq_conservative >> /etc/modules
$ echo ibm_acpi >> /etc/modules

$ apt-get install cpufrequtils

Then edit /etc/defaults/cpufrequtils to read:

ENABLE="true"
GOVERNOR="conservative"

Swedish mistranslation in Google Search

Noticed a new link today when searching on Googles swedish site. It read Mina bärbara datorer (eng. My Laptops). I wondered how Google could know I was using a laptop, but upon following the link it turned out to be a new note-taking function. The error is probably due to a machine translation of My notepads.

small screenshot

Though bärbara datorer can be a correct translation for notepads in other contexts, in this case Google should use anteckningsblock instead.

Etch post-install on IBM Thinkpad X31

Some useful things to do after installing Debian GNU/Linux 4.0 "Etch" on an IBM Thinkpad X31.

Activate CPU frequency scaling to conserve power and get rid of fan noise:

$ echo speedstep_centrino >> /etc/modules
$ echo cpufreq_conservative >> /etc/modules
$ echo ibm_acpi >> /etc/modules

$ apt-get install sysfsutils
$ echo "devices/system/cpu/cpu0/cpufreq/scaling_governor = conservative" \
    >> /etc/sysfs.conf

Get access to more capable multimedia packages by adding a Debian Multimedia mirror to the file /etc/apt/sources.list. Then:

$ apt-get install debian-multimedia-keyring

Install tpb for on-screen display of sound volume and TFT brightness. All desktop users has to be added to the nvram group.

$ apt-get install tpb
$ adduser username nvram
