Po paru próbach udało mi się odpowiednio wyedytować archiwalny plik z jednej z wcześniejszych wersji, dzięki któremu system spokojnie działa tak, jak wtedy, gdy ustawienia generowane są automatycznie podczas startu (tj. bez xorg.conf).
Głownie polegało to na podaniu prawidłowych sterowników tj. "radeon".
Do xorga wstawiłem też rozdzielczość, na której mi zależy tj. 1280x800, najbardziej zbliżonej proporcjami do natywnej. Dodam, iż działa na niej bez problemów Windows XP.
Mimo to po wejściu w System/Preferencje/Monitory nie widać tej rozdzielczości.
Ponadto monitor identyfikowany jest tam ciągle tak samo tj. Samsung Electric Company 21" (choć tak naprawdę to Samsung SyncMaster 22" - ale to chyba nie ma większego znaczenia).
Mój xorg.conf wygląda tak
Karta to ATI Radeon 9550, monitor podłączony przez DVI.# /etc/X11/xorg.conf (xorg X Window System server configuration file)

Czy można zmusić ten system do wyświetlania obrazu w rozdzielczości 1280x800?
Bardzo proszę o pomoc.
