I've got a new Asus P5E-V HDMI board with an onboard intel G35. When I connect it via VGA to the monitor everything works fine.
But when I connect it via the HDMI-DVI connector that came with the board to my Iiyama ProLite E481 things get funny. I can see the BIOS-post and everything until I start X. When I do so the screen goes black and the monitor switches off.
This is with xserver-xorg-video-intel (2:2.4.2-1) on a debian testing system with just the necessary parts from experimental to get this driver running. Just to see if the hardware is working correctly I switched to the vesa driver and can get a working screen with 1280x1024.
With just this monitor connected via the HDMI-DVI adapter the last lines of Xorg.0.log are (back with the intel driver):
(II) intel(0): Output VGA using monitor section Configured Monitor
(II) intel(0): I2C bus "CRTDDC_A" initialized.
(II) intel(0): I2C bus "SDVOCTRL_E for SDVOB" initialized.
(II) intel(0): I2C device "SDVOCTRL_E for SDVOB:SDVO Controller B" registered at
address 0x70.
(II) intel(0): I2C bus "SDVOB DDC Bus" initialized.
(II) intel(0): Output TMDS-1 has no monitor section
(II) intel(0): SDVOB: device VID/DID: 04:AE.00, clock range 25.0MHz - 165.0MHz
(II) intel(0): SDVOB: 1 input channel
(II) intel(0): SDVOB: TMDS0 output reported
(II) intel(0): Current clock rate multiplier: 8
(II) intel(0): Output VGA disconnected
(II) intel(0): Output TMDS-1 disconnected
(WW) intel(0): No outputs definitely connected, trying again...
(II) intel(0): Output VGA disconnected
(II) intel(0): Output TMDS-1 disconnected
So it seems it can't find a connected monitor.... so I connected a second one, an old 15' CRT to the VGA port (with the TFT still connected via the adapter) and tried again.
Now I can get a screen on the old VGA when I start X, but the TFT still switches off.
xrandr --prop tells me:
Screen 0: minimum 320 x 200, current 1152 x 864, maximum 1360 x 1360
VGA connected 1152x864+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1360x768 59.8
1152x864 60.0*
1024x768 60.0
800x600 60.3
640x480 59.9
TMDS-1 disconnected (normal left inverted right x axis y axis)
....the same as before, the intel driver seems to be unable to find the connected monitor, although everything (BIOS post, console messages) is displayed correctly until I start X.
Does anybody have a suggestion what to try next?
