Matthias, all I build the radeonhd driver from the latest git, and after months of blackscreening, I see light now, but it is just varying horizontal gradients of white and black of varying widths in the lower 1/3 of the screen. Also, I am getting Xorg.0.log messages I don't understand. If anyone can shed some light on these, I would appreciate it. The log entries I'm concerned with are: (II) XINPUT: Adding extended input device "Power Button" (type: KEYBOARD) (**) Option "xkb_rules" "evdev" (**) Option "xkb_model" "evdev" (**) Option "xkb_layout" "us" (II) RADEONHD(0): Attempting to disable power management (WW) RADEONHD(0): AtomBIOS command table 19 does not exist (II) RADEONHD(0): Query for AtomBIOS Exec: not implemented (WW) RADEONHD(0): Failed to set power management (II) RADEONHD(0): Query for Set Power Management: failed (II) RADEONHD(0): Attempting to disable clock gating (II) RADEONHD(0): Current Engine Clock: 400000 (WW) RADEONHD(0): AtomBIOS command table 47 does not exist (II) RADEONHD(0): Query for AtomBIOS Exec: not implemented (WW) RADEONHD(0): Unusupported SetVoltage Revision ## looks normal until the SetVoltage above. I think this is where it hangs, and the ## Close commands below are in response to my ctrl+alt+f1 (II) Power Button: Close (II) UnloadModule: "evdev" (II) Video Bus: Close (II) UnloadModule: "evdev" (II) Power Button: Close (II) UnloadModule: "evdev" (II) Microsoft Microsoft 3-Button Mouse with IntelliEye(TM): Close (II) UnloadModule: "evdev" (II) AT Translated Set 2 keyboard: Close (II) UnloadModule: "evdev" (II) UnloadModule: "synaptics" (II) Macintosh mouse button emulation: Close (II) UnloadModule: "evdev" (EE) RADEONHD(0): RHDCSStop: Command Submission backend is not active! First question: does my assessment of the sequence of things look right? Could the display hang after the 'Unusupported SetVoltage Revision'? Second question: do the 'Close' events look normal in response to ctrl+alt+f1 Last question: what is the driver supposed to do in response to an 'Unusupported SetVoltage Revision' condition?
