[Eugene Pazhitnov]

Перестали работать иксы, к сожалению, не знаю, когда, так как давно не 
покидал их. Запуск xorgcfg приводил к остановке исков без внятного 
сообщения об ошибке (connection reset by peer), единственное - в логе 
вот такая штука:

Unable to handle kernel NULL pointer dereference at virtual address 00000000
 printing eip:

Сизиф сегодняшний.

Вылечилось копированием нового конфига из рутового каталога в /etc/X11 и 
убиранием строчки 'Load  "dri"'.
