Переехал на него с убунты.
Проблема с Xorg.
Вернее с производительностью Xorg при работе в gnome-terminal.
При прокрутке вывода консоли (хоть колёсиком мышыным, хоть полосой прокрутки) Xorg начинает отжирать ~40% проца.
При работе в VIM (а также в GVIM и в "родном" арчевом VI) при прокрутке текста стрелками вниз/вверх Xorg работает уже на 70-80%.
Пробовал разные xorg.config.
Пробовал драйвера как intel, так и i810.
Ничего не изменяется.
Может подскажет кто-нибудь, где копать.
Заранее спасибо.

Попробуй еще в xorg.conf в секцию Screen подобавлять/поубирать/подставить true/false в опции:

Option "RenderAccel" "true" Option "DRI" "true"

Спасибо всем откликнувшимся. Ни один из советов не помог. Если за пару дней не найду решения, придётся возвращаться на убунту - там всё в порядке с производительностью :)
