When applications or I manually select lower resolutions it will only show in the top left corner of my screen with the correct amount of pixels. There are streaking colors coming off to the right. This happened to me on some older versions and was correct through the 11 and 12 series.

sudo lshw -c video

I'm not sure if its supposed to be showing that second unclaimed monitor or what but it seems like the correct driver is enabled. I tried to look for the xconf in the normal place but nothing was there so I guess that isn't around anymore.

As a side note scaling is enabled in the bios and works properly for the bios screen alternate install CD.

Does anyone have any tips on how to fix this?

  • Tried with bios scaling turned off and got the same exact result as with it enabled. Did not scale. – Bereg May 2 '13 at 1:51

This should be solving your problem.

  • Thank you thefourtheye. In the past I have had to use the commands you linked when all my resolutions weren't showing up. In this case all of the applicable screen resolutions / refresh rates are showing in the display settings applet. The issue is only with resolutions lower than 1400x1050 scaling to the full size of this monitor. – Bereg Apr 30 '13 at 12:41
  • You mean, after executing those commands, you are getting all the modes applicable? – thefourtheye Apr 30 '13 at 13:35
  • No all the modes were in there by default after install. It seems like the resolution / refresh for the modes is correct but they do not have switches for scaling. I think xrandr has ways to set the scaling mode for each resolution but for some reason. I checked out the manpage but I'm not getting any luck inputting the command correctly. – Bereg Apr 30 '13 at 18:07
