Description Philipp Neubeck 2009-04-16 10:10:00 UTC
Created attachment 24876 [details] /var/log/Xorg.0.log Hardware: Gigabyte GA-MA69GM-S2H with IGP Radeon X1250 lspci output: 01:05.0 VGA compatible controller: ATI Technologies Inc RS690 [Radeon X1200 Series] Two displays connected: Normal LCD Display connected to VGA and is working. LCD-TV connected to HDMI and does not show anything, i.e. it seems not to get any signal. Yet, the software seems to think, that the display is enabled, because I can move the mouse on the second monitor (of course, i cannot see it there anymore). MS Windows can use both displays correctly and some version of fglrx worked, too. I used the following xrandr command: xrandr --output DVI-D_1 --crtc 1 --mode 1024x768 --right-of VGA_1 and the attached xorg.conf. output of xrandr --verbose and the xorg.log are attached.

Try xrandr --output DVI-D_1 --mode 0x50 Maybe your monitor doesn't like 75Hz framerate despite advertising it. Though I doubt that this is the main issue, as you already tried the native 1920x1080 mode. Also try xrandr --output DVI-D_1 --set _Coherent 1 Another idea would be to try Option "UseAtomBIOS" in xorg.conf.
Comment 4 Philipp Neubeck 2009-04-19 06:09:38 UTC
# xrandr --output DVI-D_1 --mode 0x50 xrandr: cannot find mode 0x50 Setting Coherent and UseAtomBIOS both have no visible effect. In the meantime I gave a try to the radeon driver and shows output on both displays without any tweaking.

Does this issue occur with the preferred ati driver (xf86-vide-ati)? If so, please move this to the Driver/Radeon component. Development of radeonhd has pretty much halted and development focus is on the ati driver. Please see http://www.x.org/wiki/radeonhd If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.
Comment 6 Jeremy Huddleston Sequoia 2011-11-07 15:39:12 UTC
Closing due to lack of response. Please reopen and move to the Driver/Radeon component if this issue persists with xf86-video-ati
