http://bugs.freedesktop.org/show_bug.cgi?id=21388 Summary: Dual monitor setup results in blank screen on CRTC1 Product: xorg Version: unspecified Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: Driver/radeonhd AssignedTo: lverhaegen@suse.de ReportedBy: pht@spatium.org QAContact: xorg-team@lists.x.org Created an attachment (id=25111) --> (http://bugs.freedesktop.org/attachment.cgi?id=25111) xorg config I have a dual monitor setup (see attached files); the problem is that the secondary monitor (connected to dvi2) stays black. Note that these are CRT monitors. It switches to correct mode, thus is not out of range, I can verify that via the OSD menu. I can even switch it to different modes using xrandr, but it stays black. It is not a hardware issue, dual monitors work okay in the other operating system. The theory is that CRTC1 is not properly initialized or operated. This is backed up by the fact that when the first (ie. working) monitor is plugged out before starting X, the other monitor (ie. blank) is working, and when the former first monitor is plugged back and activated via xrandr, it stays black. I experienced a brief moment a working setup, which went as follows: the X server was first configured to run with the radeon driver, then it was shut down, then the radeonhd driver was configured. This setup resulted in both monitors working. After shutting down X again, all was back to previous state, as described above. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
