A Radeon X1550 (RV505) with one DVI port works great with a VGA multisync CRT and DVI-to-VGA adapter. Custom modelines, vsync and direct render are perfect, with xrandr reporting "DVI-0 connected".
However with a different monitor (an analog arcade CRT), xrandr reports "DVI-0 disconnected" and lists only a single defined mode, which does display properly. I've tried several different cables and DVI-to-VGA adapters. I'm confident the problem is software, as it worked under the last radeon driver I used (most likely current git in early March). I'm now on Debian Sid, 2.6.30-1-686-bigmem, and up-to yesterdays git of xf86-video-ati (2009-07-24). xrandr --verbose: http://pastebin.com/f2d18e989 xorg.conf: http://pastebin.com/f1ed6090a Xorg.0.log: http://pastebin.com/f180397bd lspci -v: http://pastebin.com/f77fe0021 dmesg: http://pastebin.com/f53a7facf dpkg -l: http://pastebin.com/m7b7f4fca Besides xorg.conf changes, I've tried "nomodeset" under the kernel, and xrandr --output DVI-0 --set load_detection 0 xrandr --output DVI-0 --set dvi_monitor_type analog (Both produce: X Error of failed request: BadMatch (invalid parameter attributes)). It seems similar to the following problem, yet I am using the latest ati/radeon git: http://lists.freedesktop.org/archives/xorg/2009-March/044571.html Whenever "xrandr -q" is called in this scenario, this is printed to Xorg.0.log: (II) RADEON(0): Output: DVI-0, Detected Monitor Type: 0 Dac detection success Unhandled monitor type 0 (II) RADEON(0): EDID for output DVI-0 I can manually add modes with "xrandr --newmode " and then "xrandr --addmode", however the modes can't actually be used (the video signal has no sync, and this error is displayed): (EE) RADEON(0): No encoder assigned to output! Can anyone please tell me how the xserver can correctly report (e.g. to xrandr) that a display is connected (and therefore use the rest of the xorg.conf modelines)? Is this a bug in xorg? Again this all works simply by physically changing to a different CRT monitor on the same DVI-to-VGA adapter, or by reverting to an older (3 months or so) radeon driver. Thanks! _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
