my graphic card is an nvidia 8500gt, i reinstall ideneb 1.0.5.5 but strangely, my maximal resolution is 846*5?? i don't know exactly but when i tried to change the resolution higher (1024*768) the screen turn blue and freeze, when i push the sleep mode button on my keyboard, i show the mac os desktop in 1024*768 and desappear (cause of the sleep mode lol) and when i tried to wake up the screen is all black but the pointing mouse appear and can move!
how can fix it?
