http://bugs.freedesktop.org/show_bug.cgi?id=16740 Summary: Unwanted scaling on dual monitor setup Product: xorg Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Driver/radeonhd AssignedTo: lverhaegen@suse.de ReportedBy: ahabig@umn.edu QAContact: xorg-team@lists.x.org CC: ahabig@umn.edu Created an attachment (id=17704) --> (http://bugs.freedesktop.org/attachment.cgi?id=17704) /etc/X11/xorg.conf Before the addition of scaling to the driver after the April 29th git snapshot, a dual-head configuration of a 1920x1200 external LCD on DVI-D_1 and a laptop 1400x1050 PANEL to the RightOf the LCD worked fine. There was virtual screen real estate off the bottom of the PANEL that was inaccessible, but no big deal. After the addition of scaling on commit 26ccf1177465beb2db5a2c972dd7adc17c3f457b, the laptop is forced into the scaled "letterbox" style mode, making it tiny, undreadable, and with unusable black space on the top and bottom of the screen. Which is of course exactly what the new 1920x1200Scaled mode should look like. However, it's not what I want. I don't think it's a simple matter of a bad default selection, as the native 1400x1050 mode is set as the preferred mode. Trying to make it use this via xrandr manually fails: xrandr --output PANEL --mode 1400x1050 xrandr: Configure crtc 1 failed so I think the ability to use the native mode in this case is just broken, and the scaled mode is the fallback that works. xorg.conf attached, along with -logverbose 7 X logs for two cases: the working 20080429 version (git commit 45fdec79e523f3f9637c35a3d84c1fd9e61b9b21) and the latest of the broken versions, 20080716 (git 820187b208ab1ec94a015f07e48abbb381524c89). xrandr outputs also attached. Other info which I don't thinks is relevant but can't hurt: a fully patched Fedora 9 system, using Hans Ulrich's nicely packaged radeonhd rpms, system is a T60p Thinkpad with an M56 chip. -- 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
