Package: laptop-mode-tools Version: 1.32-1 Severity: normal I using an IBM Thinkpad X40 and I noticed that even with the following set: CONTROL_DPMS_STANDBY=0
The screen blanks out with laptop-mode-tools installed and when running on the battery. If I remove laptop-mode-tools the blanking goes away, or if I'm on AC and laptop-mode is inactive. I guess I could get around this by setting the blanking time variables to really high values so that it would bother me, however it would be nicer if there was a fix. I'm not sure why this hasn't been reported before, but I guess that most people would quite like screen blanking; I guess I'm the exception :) -- System Information: Debian Release: 4.0 APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.18 Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Versions of packages laptop-mode-tools depends on: ii lsb-base 3.1-23.1 Linux Standard Base 3.1 init scrip Versions of packages laptop-mode-tools recommends: ii acpid 1.0.4-5 Utilities for using ACPI power man ii hdparm 6.9-2 tune hard disk parameters for high ii sdparm 0.98-1 Output and modify SCSI device para -- no debconf information
############################################################################### # # Configuration for Laptop Mode Tools # ----------------------------------- # # There is a "system" to the configuration setting names: # CONTROL_something=0/1 Determines whether Laptop Mode Tools controls # something # LM_something=value Value of "something" when laptop mode is active # NOLM_something=value Value of "something" when laptop mode is NOT active # AC_something=value Value of "something" when the computer is running # on AC power # BATT_something=value Value of "something when the computer is running on # battery power # # There can be combinations of LM_/NOLM_ and AC_/BATT_ prefixes, but the # available prefixes are different for each setting. The available ones are # documented in the manual page, laptop-mode.conf(8). If there is no LM_/NOLM_ # in a setting name, then the value is used independently of laptop mode state, # and similarly, if there is no AC_/BATT_, then the value is used independently # of power state. # # Some options only work on ACPI systems. They are marked ACPI-ONLY. # # Note that this configuration file is a fragment of bash shell script: you # can use all the features of the bash scripting language to achieve your # desired configuration. ############################################################################### ############################################################################### # Configuration debugging # ----------------------- ############################################################################### # Set this to 1 if you want to see a lot of information when you start/stop # laptop_mode. VERBOSE_OUTPUT=0 ############################################################################### # When to enable laptop mode # -------------------------- # # "Laptop mode" is the mode in which laptop mode tools makes the computer # consume less power. This includes the kernel "laptop_mode" feature, which # allows your hard drives to spin down, as well as various other settings which # can be tweaked by laptop mode tools. You can enable or disable all of these # settings using the CONTROL_... options further down in this config file. ############################################################################### # Enable laptop mode when on battery power.

Use this # when you have a battery that reports the wrong information, that confuses # laptop mode tools. # # Disabling data loss sensitive features is ACPI-ONLY. ############################################################################### # Disable all data loss sensitive features when the battery level (in % of the # battery capacity) reaches this value.

You can add things to "auto", e.g. "auto /dev/hdc3". You can # also specify mount points, e.g. "/mnt/data". PARTITIONS="auto /dev/mapper/*" # If this is enabled, laptop mode tools will assume that SCSI drives are really # SATA drives that only _look_ like SCSI drives, and will use hdparm to control # them.

This causes disks to spin up, which is not very nice when # you're trying to save power. The syslog.conf can be tweaked to *not* sync # a given file, by prepending the log file name with a dash, like this: # # mail.* -/var/log/mail/mail.log # # Using the following options, you can let laptop mode switch between # different syslog configurations depending on whether you are working on # battery or on AC power. To set this up, start by configuring these options # for your syslog daemon, and then run lm-syslog-setup to create the various # files. Then edit the laptop mode-specific syslog configuration files to # remove the syncs only when laptop mode is active. ############################################################################### # Should laptop mode tools control which syslog.conf should be used? CONTROL_SYSLOG_CONF=1 # Laptop mode tools controls syslog.conf by replacing /etc/syslog.conf (or # whatever you specify in SYSLOG_CONF) by a link to the files configured here. # NOTE: these files are NOT created by default, and if they do not # exist this feature will not work.

Laptop mode will call the # scripts in a state-"stop" directory with the "stop" parameter when entering # the state in question, and it will call the same scripts with the "start" # parameter when leaving the state.
