It rather becomes smaller and leaves blank spaces on +the right and bottom sides. And the following error message shows up: + +X Error of failed request: BadMatch (invalid parameter attributes) + Major opcode of failed request: 139 (RANDR) + Minor opcode of failed request: 7 (RRSetScreenSize) + Serial number of failed request: 36 + Current serial number in output stream: 38 + +Before xrandr attempts to apply the transformation matrix requested +by "scale", "transform" or "scale-from" options, it disables the +CRTCs for which the transformed image's dimensions are larger than the +target display's resolution/mode. But, when the image is smaller, it +does not disable the CRTCs, and proceeds with applying the +transformation (involves framebuffer dimension changes). This works well +for all the scale values and transitions except for the above mentioned +transitions. + +This patch fixes such issues! + +Signed-off-by: Arsalan-Awan <Arsalan_Awan@mentor.com> +--- + xrandr.c | 31 +++++-------------------------- + 1 file changed, 5 insertions(+), 26 deletions(-) + +diff --git a/xrandr.c b/xrandr.c +index dcfdde0..d2872ef 100644 +--- a/xrandr.c ++++ b/xrandr.c +@@ -1723,8 +1723,7 @@ apply (void) + XGrabServer (dpy); + + /* +- * Turn off any crtcs which are to be disabled or which are +- * larger than the target size ++ * Turn off any crtcs which are to be disabled + */ + for (c = 0; c < res->ncrtc; c++) + { +@@ -1736,33 +1735,13 @@ apply (void) + continue; + + /* +- * If this crtc is to be left enabled, make +- * sure the old size fits then new screen ++ * Once the scale value is changed in xrandr, omitting the ++ * following if statement causes the display to fail to ++ * turn back ON after it goes to sleep due to inactivity. + */ + if (crtc->mode_info) +- { +- XRRModeInfo *old_mode = find_mode_by_xid (crtc_info->mode); +- int x, y, w, h; +- box_t bounds; +- +- if (!old_mode) +- panic (RRSetConfigFailed, crtc); +- +- /* old position and size information */ +- mode_geometry (old_mode, crtc_info->rotation, +- &crtc->current_transform.transform, +- &bounds); +- +- x = crtc_info->x + bounds.x1; +- y = crtc_info->y + bounds.y1; +- w = bounds.x2 - bounds.x1; +- h = bounds.y2 - bounds.y1; +- +- /* if it fits, skip it */ +- if (x + w <= fb_width && y + h <= fb_height) +- continue; + crtc->changing = True; +- } ++ + s = crtc_disable (crtc); + if (s != RRSetConfigSuccess) + panic (s, crtc); +-- +2.7.4 + |
