Priority: medium Bug ID: 80678 Assignee: dri-devel@lists.freedesktop.org Summary: xrandr scaling / transform does not work with radeon Severity: normal Classification: Unclassified OS: Linux (All) Reporter: h.judt@gmx.at Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
Scaling doesn't work with radeon. Screen rotation does work, though.
On a laptop with intel driver, the following works fine, except the mouse pointer is confined to the mode area, but I believe that is a known xorg-server bug to which a patch is available in bug #39949: xrandr --fb 1920x1080 --output eDP1 --mode 1600x900 --scale-from 1920x1080
The same command, adapted to the radeon output device doesn't work. Same software configuration (xorg-1.15.99.903, libdrm-git, mesa-git, xf86-video-ati-git, various kernel versions (at the moment 3.15.2)).

Is scaling not implemented in radeon?

--- Comment #1 from Alex Deucher agd5f@yahoo.com --- I'm not sure if EXA supports those options. You might try glamor.
https://bugs.freedesktop.org/show_bug.cgi?id=80678
--- Comment #2 from Harald Judt h.judt@gmx.at --- No, it doesn't work with glamor either. Besides, I'd like to use EXA because of xv support.
Actually, I notice one difference after executing xrandr --fb 1920x2400 --output HDMI-0 --mode 1920x1200 --scale-from 1920x2400
The vertical panel seems to stretch/extend to the new vertical size (2400). However, the intended scaling doesn't get applied.
xrandr --verbose before and after this command shows no differences.

xrandr --verbose output after applying above xrandr command

glamor supports Xv as well.

--- Comment #5 from Harald Judt h.judt@gmx.at --- Maybe I forgot to compile in support for xv then. One way or the other, scaling doesn't work.

--- Comment #6 from Sebastian Wick sebastian@sebastianwick.net --- I'm running into the same problem. The transform matrix doesn't seem to get updated at all.

Fix RandR CRTC transforms
Currently, Xorg will only transform the cursor as of the first time the cursor image changes after a transform is set.

--- Comment #8 from Harald Judt h.judt@gmx.at --- Thanks for fixing it. Unfortunately, it comes too bit late, and I can no longer test this because my old graphics card went to the gpu nirvana :-(
That said, hopefully it helps Sebastian and other users.

--- Comment #9 from Sebastian Wick sebastian@sebastianwick.net --- It's working. Thanks, Michel!
