Good morning radeonhd mailinglist,

bridgman from the forum suggest that I present my interesting new
bug here to the mailinglist.

I am on a Toshiba Satellite A350-12D/ Kubuntu 9.04 machine with a VGA
compatible controller: ATI Technologies Inc Mobility Radeon HD 3650.

When I use the latest fglrx or Catalyst driver (9.4), X starts, but I get a
blank screen. Xorg.0.log gives me messages like:

(EE) fglrx(0): Unknown EDID version 0
(II) fglrx(0): Display1: Failed to get EDID information.
(II) fglrx(0): Connected Display2: TV on TVDAC [tv]
(II) fglrx(0): Display2: No EDID information from DDC.
(EE) fglrx(0): Unknown EDID version 0

(EE) fglrx(0): [pcie] Failed to gather memory of size 0Kb for PCIe. Error (-1)

The entire thread can be found here,, including the
Xorg.0.log-files and some
speculations about RAM missmanagement.

Since I am using "vesa"-mode with a terribly wrong resolution on my screen, I
gave version 1.2.5 of the radeonhd driver via git a chance.
That gave very interesting results:

(EE) RADEONHD(0): rhdAtomLvdsDDC: unknown record type: b8
(EE) RADEONHD(0): D1CRTCDisable: Failed to Unsync CRTC 1
(EE) RADEONHD(0): rhdAllIdle: unable to stop CRTC: cannot idle MC

Fatal server error:
AddScreen/ScreenInit failed for driver 0
