Running seamless with dual monitors causes cropping

Reported by: mitchellj Owned by:
Priority: major Component: GUI/seamless
Version: VirtualBox 4.1.18 Keywords: seamless cropping resolution small
Cc: Guest type: Windows
Host type: Linux

Description

If I run Virtual Box (Ubuntu 12.04 Host, Windows 7 Guest) in Seamless mode with a dual monitor setup on the host for some reason the Virtual Box guest crops the work area to the bottom 1/5 of my desktop.

I've noticed this only happens when both my monitors are enabled, if I disable one in X11 or CCC the seamless springs back to life again.

Checking the windows 7 display properties the main monitor gets set to 800x600 when using seamless.

Things I have tried and checked

  • Video Memory ( I have assigned up to 256Mb )
  • Additionals installed ( I have installed the latest version, and even tried booting to safe mode to install the WDDM 3D drivers)
  • Press CTRL+G for resizing, afraid this doesn't work
  • Manually resizing the windows desktop from 800x600 the correct resolution - doesn't change the cropping
  • Check Full screen works ok (it does)
  • Install latest video drivers on linux (done)

I have attached the X11.org file, a screenshot, and the VBox.log file. I have asked in the irc channel and the suggestion was to raise a bug.

Upgrading to 4.1.20 does not resolve this issue I'm afraid :|

Re-doing my Xorg.conf file (and removing secondary Screen segment) fixed the issue. So it looks like virtual box may be just using the wrong screen settings in Xorg.conf (assuming it uses this file as its reference).

I've attached the secondary xorg.conf file for more info.

Same problem for me. I just can´t make it work by following your comments. My config file looks little different but it looks just fine.

Im running same Ubuntu version, Win7 X64 inside virtualbox and latest fgrlx driver.

I attach my Xorg.conf file. Hope you can take me to right direction.
