VirtualBox virtual machine - Debian stable (Lenny) has higher screen resolution than my monitor

  • 772

I installed debian in vm in virtualbox and it has 1280x1024 resolution, while physical screen is 1024x768... So I'm getting scrollable virtualbox window and I have to scroll it. It's pretty hard to work on it. I tried:

  • Change resolution in gnome... There's no option to choose resolution (just window with blank buttons)
  • Edit xorg.conf... xorg.conf is blank
  • I googled and found out that it's normal for xorg.conf to be blank in this version and that I can use xrandr. I tried xrandr -s 1024x768... I got "size 1024x768 not found in available modes"
  • sudo dpkg-reconfigure xserver-xorg doesn't do anything. It only lets me to select keyboard layout and that's all. No xorg.conf is created.
  • I turned off X and tried X -configure but I got completely blank black screen so I restarted vm. After restarting it I looked into xorg.conf and it's still blank.

Any ideas?

  1. I had same problem than you. I edited /etc/X11/xorg.conf with:

    Section "Screen" Identifier "Default Screen" Device "Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller" Monitor "Monitor genérico" DefaultDepth 24 SubSection "Display" Modes "1024x768" EndSubSection EndSection

    And restarted X server using CTRL+ALT+BackSpace (or from initial display botom).

    The only one display conf that It works is 1024x768, when I'm using 1280x800 in windows XP. Now, when I select complete display in VirtualBox I get a nice display but black unused spaces on left and right.

  2. Have you tried simply resizing the VirtualBox window? Worked for me with the VirtualBox drivers installed in the guest OS - changed the resolution to the size of the window.

  3. i installed the virtual box modules through the package manager in debian and that did the trick
