[Linux-Biella] Ati Mobility Radeon 7500 Dual Head su UBUNTU 7.04

[Simone Stomboli]

Ho appena effettuato l'avanzamento 6.10 -> 7.04
Non funziona piu' il dual-head...
...o meglio, funziona se faccio il boot con il monitor
secondario scollegato, poi sospendo il laptop e
ricollego.
In caso contrario funziona solo il secondario.
Fino a ieri pero' funzionava (con la 6.10)
Cos'e' una macumba?
Allego le sez. Device e Screen di etc/x11/xorg.conf
