Проблема такая: Появилась видеокарта ATI HD 2900 PRO, снес драйвера
NVIDIA, из ati-driver-installer сгенерировал пакеты для своего дистрибутива, установил. В 2D нареканий нет, все хорошо, но при попытке запуска даже glxinfo и glxgears Х-ы перезагружаются.
Система: C2D E6300, ATI HD 2900 PRO, Fedora 7.

использовал NVIDIA, так что м.б. что-то упустил в настройке.
