I am getting the following errors:

xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600
61.0 640x480 60.0

When I am trying to increase my Guest OS resolution to 1290X1080, while tried following steps mentioned HERE. Prior to that I was able to change the resolution by the above mentioned steps, but after a update to CENTOS 6.5 to 6.6, I am facing this error.Lots of people are having the same problem, but no solution I could not get my issue resolved.

My current system configuaration:

GUEST OS        : CENTOIS 6.6
HOST OS         : WIndows 7 enterprise
Display Adapter : Intel HD 
VirtualBox      : 4.6.3
VBoxGuestaddition is also succesfully installed and up and running

The result from CENTOS, when I do a lspci -vnn

Any solution to this problem ?

EDIT 2 :

I am able to get it solve to some extent by editing(creating) xorg.conf file in /etc/X11/ , the file code I am sharing below

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
        HorizSync   28.0 - 70.0
        VertRefresh     56.0 - 75.0
EndSection

Section "Device"
        Identifier  "VMware SVGA"
        Driver      "vesa"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes     "1920x1080_60.00"
        EndSubSection
EndSection

Now what is the problem ?

Actually after creating the xorg.conf file I am able to get few more resolution, but not the one(1920*1080) resolution .

  • I flagged your other question as a duplicate of this one, so we only have one place to work from. Try reading this support post, and deleting /etc/X11/xorg.conf After doing so, tell me if XOrg autoconfigures correctly. If that doesn't help, either upgrade CentOS to 7 or downgrade VirtualBox as the post suggests. – eyoung100 Jun 29 '15 at 4:15
  • Nope @eyoung100 dude, the one I asked here, I was able to solve this by editing(creating) xorg.conf file. Now I am able to get few more resolution but not the desired resolution of 1920*1080 – Dimag Kharab Jun 29 '15 at 4:17

    Include the information from your other question here, by editing the above post, so that readers know the problems are related, and then read the link I gave you. Even with a xorg.conf file, I would hazard a guess that you can't get above 1024x768, as the post suggests. – eyoung100 Jun 29 '15 at 4:21
  • Oh my gosh ... is it ? – Dimag Kharab Jun 29 '15 at 4:25
  • @eyoung100 I am able to get resolution higher than 1024x768 etc but not only 1920*1080 , see the screenshot – Dimag Kharab Jun 29 '15 at 4:43
