https://bugs.freedesktop.org/show_bug.cgi?id=59982 --- Comment #24 from Alex Deucher --- If the card is not posted by the sbios, the display hardware is disabled until the driver attempts to initialize it. The display controller enable bit is bit 0 of CRTC_CONTROL (0x6e70 + crtc_offset). The DAC enable bit is bit 0 of DAC_ENABLE (0x6790). -- You are receiving this mail because: You are the assignee for the bug.
