[Nouveau] [Bug 15753] New: [Dualhead, randr12]
http://bugs.freedesktop.org/show_bug.cgi?id=15753
Summary: [Dualhead, randr12]
Product: xorg
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: nouveau at lists.freedesktop.org
ReportedBy: xake at rymdraket.net
QAContact: xorg-team at lists.x.org
My system have two monitors connected to my system.
My xorg.conf starts VGA-0 to the left of DVI-A-0.
Both starts at resolution 1280x1024 by default (not changed by me).
VGA-0 is capable of running the resolution 1600x1200, but here comes the
problem:
xake at lillen ~ $ xrandr --output VGA-0 --mode 1600x1200
xake at lillen ~ $ xrandr
Screen 0: minimum 320 x 200, current 2560 x 1200, maximum 3000 x 3000
VGA-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 352mm
x 264mm

640x480 84.6 75.0 72.8 66.7 60.0
720x400 87.8 70.1
DVI-A-0 connected 1280x1024+1280+0 (normal left inverted right x axis y axis)

400x300 120.6
320x240 120.1
DVI-D-0 disconnected (normal left inverted right x axis y axis)
As you can see in this output the "current" for "Screen 0"
is less then the
width of VGA-0 and DVI-A-0 making a part of the left screen also appere on the
right.
However if I do:
xake at lillen ~ $ xrandr
Screen 0: minimum 320 x 200, current 2560 x 1200, maximum 3000 x 3000
VGA-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 352mm

Then as you can see everything works nice.
So it seems changing the resolution the output of VGA-0 (theleft screen) does
not setup a correct screen size, but with xrandr turn off DVI-A-0 and restore
its setup again both monitors seems to work nice.

http://bugs.freedesktop.org/show_bug.cgi?id=15753 --- Comment #2 from Maarten Maathuis <madman2003 at gmail.com> 2008-04-29 04:06:49 PST --- I'm wondering if this should be closed with NOTABUG or NOTOURBUG. It's certainly not our bug, because the driver is doing precisely what xrandr tells you. Secondly you may actually be getting what you ask for, but maybe not what you want. - You put the monitors into 1280x1024 and put one right of the other, at that point the coordinate reference of the 2nd monitor is fixed. Then you increase the other to 1600x1200, but never ask for a new position of the 2nd one. - Wether this is desirable beheaviour is something different all together. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

He, I guess you are right. This seems like a NOTABUG since as you said xrandr
did what I told it to do. Then that xrandr as a screen manipulating tool can be
becuse of that somewhat confusing, that is another story for another day.
