У меня в ноуте процессор Core 2 Duo 1200Mhz.
После установки Xubuntu 14.04 процессор работает на пониженной частоте. Обнаружил совсем недавно. В прежних версиях убунты частота менялась как и положено. Поэтому на этой версии даже и не смотрел на какой частоте работает.
Пробовал разные варианты решения, ничего не помогает.
Вот что выдает sudo cpufreq-info

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 800 MHz - 1.20 GHz
available frequency steps: 1.20 GHz, 800 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 800 MHz and 800 MHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).
