Yakui, can you take a look at this?

Comment 3 Eric Appleman 2009-10-05 20:17:19 UTC

This bug also applies to the proper command that was implemented to do panel-fitting with KMS.

The "aspect" option takes, but the screen is corrupted.

I'll file a separate  bug for it.

The panel_fitting can also be configured in KMS. But the command is different with that in UMS mode.
   >UMS mode: xrandr --output LVDS --set "PANEL_FITTING" "full aspect"(center, full)
   >KMS mode: xrandr --output LVDS1 --set "scaling mode" "Full" ("Center" or "Full aspect"

Then you can switch to the different display mode.

The corruption issue will be tracked in bug24339.
So this bug will be marked as resolved.

Using xf86-video-intel-2.9.0, the suggested command does not work here:

$ xrandr --output LVDS1 --set "scaling mode" "Full aspect"
X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  148 (RANDR)
  Minor opcode of failed request:  11 (RRQueryOutputProperty)
  Serial number of failed request:  27
  Current serial number in output stream:  27

Also the manpage still says to use the PANEL_FITTING property.

Comment 6 ykzhao 2009-10-12 02:38:59 UTC

From the xrandr output it seems that you uses the modified kernel.
In the upstream kernel the property of scaling mode should be:
  >scaling mode:	Full
		supported: None         Full         Center       Full aspect

But on your box the property of scaling mode is :
   >scaling mode:	Fullscreen
		supported: Non-GPU      Fullscreen   No scale     Aspect 

Please use the property on your box to change the scaling mode.

Thanks.
