сейчас вот посидел-поразбирался и направился в Synaptik просмотреть пакеты и нашел пакет (!) powersave , поставил его и теперь
# which powersave
/usr/bin/powersave
# powersave
Usage: powersave {-f|-l|-A} {-u|-U|-m} -[crbBsSaTFVtxKL] [-p percent] [-v level] [-e scheme_name] -k [brightness level]
[-h|--help] -i [device class] -I [device class] -J [device class] -j [device number]
Suspend/Standby:
-U, --suspend-to-disk set machine into suspend-to-disk (ACPI S4/APM suspend)
-u, --suspend-to-ram set machine into suspend-to-ram (ACPI S3/APM suspend)
-m, --standby set machine into standby (ACPI S1/APM standby)
CPUFreq modes:
-f, --performance-speed set cpufreq to performance mode
-l, --powersave-speed set cpufreq to powersave mode
-A, --dynamic-speed set cpufreq to dynamic mode
-g, --set-dynamic-performance set cpufreq dynamic performance
-G, --get-dynamic-performance get cpufreq dynamic performance
-o, --set-governor set cpufreq governor
-O, --get-governor get cpufreq governor
-c, --cpufreq-state-info print out the current cpufreq policy
Throttling:
-p <x>, --set-throttling-percent <x> throttles processors of machine by X percent
-t, --throttling-info prints out current throttling state
Schemes:
-x, --list-schemes show all available schemes
-X, --get-scheme-description show the description of scheme
-e <x>, --set-active-scheme <x> switch currently active scheme
Brightness:
-k, --set-brightness <x> set current brightness level
-K, --get-brightness get current brightness level
-L, --get-brightness-levels get number of brightness levels
CPU hotplugging:
-E --cpu-enable <x> enable a specific CPU starting from 0
-D --cpu-disable <x> disable a specific CPU starting from 0 (CPU 0 can't be disabled)
Print information:
-b, --battery-info general battery info
-B, --detailed-battery-info info of each battery
-S, --apm-acpi prints out whether APM or ACPI is supported
-a, --ac-status-info power supply info (AC/Battery)
-T, --get-thermal-info thermal Info
-F, --get-fan-info fan Info
-v <x>, --verbose <x> Verbose level (see manpage for values)
-V, --version current compiled version
Все равно, что-то то ли то, то ли не то..,
Я не понимаю , а зачем ставить еще какие-то пакеты ведь система (и среда DE) как-то ж "Завершает сеанс пользователя" , я просто хотел бы узнать по какой команде и не более ?
