I have an Samsung eh5000 HDTV that I connect to my Intel Mobile Ivy Bridge chipset via HDMI1 as reported by xrandr. Without modification xrandr reports the display's native resolution as
1920x1080 60.0 + 59.9 30.0 24.0 30.0 24.0* This is confusing because it lists 30.0 and 24.0 twice each. I discovered that I could switch to either one by specifying --rate 30/--rate 29.97 or --rate 24/--rate 23.98. With the attached patch, I have added one more decimal everywhere a frequency is reported so that now it's clearer what the supported refresh rates are and how to switch to them: 1920x1080 60.00 + 59.94 30.00 24.00 29.97 23.98* Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=75086 Signed-off-by: Kevin Mitchell <[email protected]> --- xrandr.c | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) diff --git a/xrandr.c b/xrandr.c index 0a182c3..b25da47 100644 --- a/xrandr.c +++ b/xrandr.c @@ -1566,7 +1566,7 @@ crtc_apply (crtc_t *crtc) rr_outputs[o] = crtc->outputs[o]->output.xid; mode = crtc->mode_info->id; if (verbose) { - printf ("crtc %d: %12s %6.1f +%d+%d", crtc->crtc.index, + printf ("crtc %d: %12s %7.2f +%d+%d", crtc->crtc.index, crtc->mode_info->name, mode_refresh (crtc->mode_info), crtc->x, crtc->y); for (o = 0; o < crtc->noutput; o++) @@ -3641,7 +3641,7 @@ main (int argc, char **argv) XRRModeInfo *mode = find_mode_by_xid (output_info->modes[j]); int f; - printf (" %s (0x%x) %6.1fMHz", + printf (" %s (0x%x) %7.2fMHz", mode->name, (int)mode->id, (double)mode->dotClock / 1000000.0); for (f = 0; mode_flags[f].flag; f++) @@ -3652,10 +3652,10 @@ main (int argc, char **argv) if (j < output_info->npreferred) printf (" +preferred"); printf ("\n"); - printf (" h: width %4d start %4d end %4d total %4d skew %4d clock %6.1fKHz\n", + printf (" h: width %4d start %4d end %4d total %4d skew %4d clock %7.2fKHz\n", mode->width, mode->hSyncStart, mode->hSyncEnd, mode->hTotal, mode->hSkew, mode_hsync (mode) / 1000); - printf (" v: height %4d start %4d end %4d total %4d clock %6.1fHz\n", + printf (" v: height %4d start %4d end %4d total %4d clock %7.2fHz\n", mode->height, mode->vSyncStart, mode->vSyncEnd, mode->vTotal, mode_refresh (mode)); mode->modeFlags |= ModeShown; @@ -3682,7 +3682,7 @@ main (int argc, char **argv) if (strcmp (jmode->name, kmode->name) != 0) continue; mode_shown[k] = True; kmode->modeFlags |= ModeShown; - printf (" %6.1f", mode_refresh (kmode)); + printf (" %7.2f", mode_refresh (kmode)); if (kmode == output->mode_info) printf ("*"); else @@ -3703,13 +3703,13 @@ main (int argc, char **argv) if (!(mode->modeFlags & ModeShown)) { - printf (" %s (0x%x) %6.1fMHz\n", + printf (" %s (0x%x) %7.2fMHz\n", mode->name, (int)mode->id, (double)mode->dotClock / 1000000.0); - printf (" h: width %4d start %4d end %4d total %4d skew %4d clock %6.1fKHz\n", + printf (" h: width %4d start %4d end %4d total %4d skew %4d clock %7.2fKHz\n", mode->width, mode->hSyncStart, mode->hSyncEnd, mode->hTotal, mode->hSkew, mode_hsync (mode) / 1000); - printf (" v: height %4d start %4d end %4d total %4d clock %6.1fHz\n", + printf (" v: height %4d start %4d end %4d total %4d clock %7.2fHz\n", mode->height, mode->vSyncStart, mode->vSyncEnd, mode->vTotal, mode_refresh (mode)); } @@ -3799,7 +3799,7 @@ main (int argc, char **argv) if (rate == rates[i]) break; if (i == nrate) { - fprintf (stderr, "Rate %.1f Hz not available for this size\n", rate); + fprintf (stderr, "Rate %.2f Hz not available for this size\n", rate); exit (1); } } -- 1.9.0.rc3 _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
