https://bugzilla.novell.com/show_bug.cgi?id=370656 Summary: Only clone mode available when using 2x DVI-D (radeonhd) Product: openSUSE 11.0 Version: Alpha 2plus Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org AssignedTo: mhopf@novell.com ReportedBy: sndirsch@novell.com QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Date: Thu, 13 Mar 2008 18:55:44 +0100 From: Matthias Hopf <mhopf@suse.de> To: xorg@lists.freedesktop.org Subject: RandR: multi-referenced monitor sections & problems with them I just stumbled over some strange behavior, and it definitely changed past Xserver 1.4.0 (don't know the exact version yet, bisecting this would be probably worth it). A snippet of the config I'm testing is Section "Monitor" Identifier "M1" EndSection Section "Monitor" Identifier "M2" Option "Right-Of" "M1" EndSection Section "Device" Identifier "D" Driver "radeonhd" Option "monitor-DVI-I_1/digital" "M1" Option "monitor-DVI-I_2/digital" "M2" EndSection Section "Screen" [...] Identifier "S" Device "D" Monitor "M1" EndSection [...] So basically a static multi-monitor setup for RandR 1.2, with one of the monitors additionally referenced in the Screen section. This monitor reference shouldn't be used at all, because the driver sets use_screen_monitor to FALSE for all outputs. This used to work - however, beginning with 1.4.90 the multi-monitor setup fails if and only if I use the two digital DVI outputs on this card, with DVI and VGA it works fine, with DVI/d and DVI/a it also works fine. If I remove the reference to the M1 monitor in the Screen section it works fine. If I add another monitor and reference it in the Screen section instead it works fine. It's probably difficult to reproduce this with another driver, but this shouldn't be a driver issue. Does anybody have a clue WTF is going on here, is this considered standard behavior or rather a bug? If it's standard, why is its behavior depending on the outputs (and not on the monitors)?
