Summary: VSync loss after rotation to portrait mode
Product: Mesa
Version: 7.9
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/R600
AssignedTo: dri-devel@lists.freedesktop.org

Xorg log file
I have a monitor that can be rotated from landscape (1920x1080) to portrait
mode (1080x1920) and vice versa. When I use the monitor in landscape mode, I
can see a perfectly vsynced desktop. Once I move to portrait mode (xrandr -o
left), the vsync is lost and scrolling or moving windows becomes a tearing
fest.
Compiz is running in both cases, with its "sync to vblank" setting enabled. (If
I disable compiz, I get tearing in both landscape and portrait mode - even
worse!)
This is on Ubuntu 10.10:
- 'uname' gives Linux 2.6.35-24-generic
- 'glxinfo' gives
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: Mesa DRI R600 (RV770 9442) 20090101 TCL DRI2
OpenGL version string: 2.1 Mesa 7.9-devel
My Xorg.0.log is attached.

Everytime the X server receives "damage" on the "normal" frontbuffer it will update the rotated frontbuffer. This transform happens outside compiz/opengl (which was used to get the vsync). This is just a generic story, not sure if this is easy to fix for amd hardware. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
