Radeon driver fails with ThinkPad T60 dock/DVI

**seppoi** · 09-24-2009, 09:41 AM

Hi,

Any idea why DVI output is not found by radeon driver (xf86-video-ati-6.12.4.tar.bz2 installed to Ubuntu Jaunty)? Radeonhd driver finds DVI as well as other video outputs (laptop panel and VGA).

I'm not able to copy & paste the /var/log/Xorg.0.log here due to size limitation but here is the the result of grepping string DVI.

Code:

(II) RADEON(0): Output DVI-0 has no monitor section
(II) RADEON(0): I2C bus "DVI-0" initialized.
  XRANDR name: DVI-0
  Connector: DVI-I
(II) RADEON(0): I2C device "DVI-0:E-EDID segment register" registered at address 0x60.
(II) RADEON(0): I2C device "DVI-0:ddc2" registered at address 0xA0.
(II) RADEON(0): Output: DVI-0, Detected Monitor Type: 0
(II) RADEON(0): Output: DVI-0, Detected Monitor Type: 0
(II) RADEON(0): Output DVI-0 disconnected

There is nothing special in /etc/X11/xorg.conf. The virtual option is there because otherwise setting up 1680x1050 24 bit color desktop with DVI connected Dell monitor fails (with radeonhd).

Code:

please pastebin your full xorg logs from radeon and radeonhd.

**bridgman** · 09-24-2009, 10:00 AM

If you're not familiar with pastebin, go to www.pastebin.com, .ca, .de, whatever, and paste your log into the web form. When you submit, the page will return a URL; post that URL here.

Thanks agd5f and bridgman! My log files are now in pastebin.

Radeonhd http://pastebin.com/m543521d7

Radeon http://pastebin.com/d33e75103

In both cases I rebooted the PC. With radeonhd the laptop display goes by default to DVI but as low resolution non-native mode. Then I add in my docked script with xrandr 1680x1050 mode and set the output to only DVI

xrandr --newmode 1680x1050 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync
xrandr --output PANEL --off
xrandr --output VGA_1 --off
xrandr --addmode DVI-D_1 1680x1050
xrandr --output DVI-D_1 --mode 1680x1050

With radeon I tried the same but replaced DVI-D_1 with DVI-0 as that seems the right keyword. Earlier versions of radeonhd didn't require that modeline. Later versions do. The EDID communication with DVI probably fails with radeonhd?

Radeon stays on laptop panel only and xrandr keeps complaining about disconnected DVI-0. Laptop panel seems to work OK. I didn't try VGA.

Cheers,
Seppo

Nether driver is able to get an EDID from your monitor. RHD is able to detect something since it implements tmds load detection. However, you can force the monitor on with radeon however:
xrandr --newmode 1680x1050 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync
xrandr --addmode DVI-0 1680x1050
xrandr --output DVI-0 --mode 1680x1050

What's the output of xrandr anyway? I have a T60 with a docking station and 2 external deisplays (DVI and VGA) too. xrandr should say sthg like this:

Here is the output before trying to add modes to DVI-0. It says it's disconnected.

Radeonhd used to get EDID information since DVI output did work without telling 1680x1050 mode parameters when I was using elder Ubuntu Intrepid. The Dell LCD monitor and the dock were the same.

However, you can force the monitor on with radeon however:
xrandr --newmode 1680x1050 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync
xrandr --addmode DVI-0 1680x1050
xrandr --output DVI-0 --mode 1680x1050

Nothing happens with that. With the last xrandr command this is appended to Xorg.0.log

How is it possible that you are able to use 1920x1200 mode without Virtual in display subsection? Is it because your EDID discovery works or is your hardware different with more graphics RAM?

I tried to add virtual to your xorg.conf but radeon still refuses to output to DVI-0.

What dependencies are there for the radeon driver? Is it possible that my tarball --prefix=/usr installs (radeonhd, radeon, drm) on top of Ubuntu has breaked something in X related to EDID?

**Killigrew** · 09-30-2009, 03:19 AM

Hi

I don't have any problem to use a 1920x1050 resolution via dvi on my T60.
I'm using the latest xorg edgers build of the radeon driver with kms enabled in karmic alpha.

greetings
