Summary: IBM T40P + Radeon 9000 M9 + Dual head
I've been trying to operate both the laptop panel + the external DVI for a while
now without any success. I can work either the laptop panel or the DVI port
separately but not both of them together. After some games as explained below
X finally detects both heads but is not able to operate both of them together.
I have looked through all the bugs I could find with similar issues and have
tried plenty of various configuration changes without luck.
Versions tried: XFree 4.3 (debian version) / 4.4 (website version) and now Xorg
6.8.1 / 6.8.1 with Hui's patch (from bug 1559) / cvs head from today.
XFree behaves pretty much like an unpatched 6.8.1, while 6.8.1 and the cvs head
versions produce about the same results.
Basically HEAD and any version with Huj's patch produce much better results but
there seems to be one last problem, the monitor itself does not get detected for
some reason, attached are Xorg.log and my config.
Since I don't know how to attach a file here I will only show excerpts of the
Xorg.log that may be relevant.
(II) RADEON(0): Primary:
Monitor -- TMDS
Connector -- DVI-D
DAC Type -- TVDAC/ExtDAC
TMDS Type -- NONE
DDC Type -- NONE
(II) RADEON(0): Secondary:
Monitor -- CRT
Connector -- VGA
DAC Type -- Primary
TMDS Type -- NONE
DDC Type -- VGA_DDC
(II) RADEON(0): PLL parameters: rf=2700 rd=12 min=20000 max=35000; xclk=20000
(II) RADEON(0): DFP table revision: 3
(WW) RADEON(0): Failed to detect secondary monitor DDC, default HSync and VRefre
I have tried both
Option "MonitorLayout" "TMDS,AUTO"
Option "MonitorLayout" "TMDS,LVDS"
both produce the same problem, though slightly different text in the log excerpt
above. both cases do not detect the second monitor.
Any input would be greatly appreciated. I will respond to any query and
provide any details necessary.
