hello,
i have a display pb with the xrandr scale option.
in some sessions, when i use it there is no more display: there is a fixed image, only the mouse cursor can move on the screen. this cursor can detect windows borders and other interactive elements (ie: screen elements who should appear but who stay completely masked by the fixed image).
So it's more or less like a blank screen, but i can continue to do actions in a blind way.
(the pb exists also for the transform and rotate options)
example:
[guigui@ctkarch ~]$ xrandr --output VGA-1 --scale 0.9x0.9 --verbose
(light zoom)
the screen become black during 1 second (it's ok) then it displays a fixed image.
if i type in a blind way: xrandr --output VGA-1 --scale 1x1 --verbose
=> all come back to a correct display.
[guigui@ctkarch ~]$ xrandr --output VGA-1 --scale 0.9x0.9 --verbose
crtc 0: disable
screen 0: 1296x810 335x209 mm 98.11dpi
crtc 0: 1440x900 59.9 +0+0 "VGA-1"
[guigui@ctkarch ~]$ xrandr --output VGA-1 --scale 1x1 --verbose
screen 0: 1440x900 371x232 mm 98.44dpi
crtc 0: 1440x900 59.9 +0+0 "VGA-1"
[guigui@ctkarch ~]$
i don't see error message. including the logs.
i never see a change during a session: it works (or not) since the begining of a session. it seems a random pb.
the resolution changes always works. example:
[guigui@ctkarch ~]$ xrandr --output VGA-1 --mode 1280x1024 --verbose
crtc 0: disable
screen 0: 1280x1024 338x270 mm 96.05dpi
crtc 0: 1280x1024 75.0 +0+0 "VGA-1"

[guigui@ctkarch ~]$
i use xf86-video-nouveau 1.0.1-1
screen: LG FLATRON W1952TE (1440x900)
[guigui@ctkarch ~]$ uname -a
Linux ctkarch 3.4.7-1-ARCH #1 SMP PREEMPT Sun Jul 29 20:05:01 UTC 2012 i686 GNU/Linux
[guigui@ctkarch ~]$
i tried with nvidia (302.17-4) in place of nouveau: it's slow but it seems to work (i only test 2 or 3 sessions).
i downgraded my system to 2012-06-17 ARM (to have xf86-video-nouveau 0.0.16_git20120615-1): no effect on my pb.
i tried the xorg-server patch for cursor scaling pb:
https://bugs.freedesktop.org/show_bug.cgi?id=39949#c20
=> the patch works for its pb, but there is no effect on my pb.
what can i do?
thanks in advance!
