Screen Resolution Oracle Virtual Box

I installed Oracle virtual Box for Windows 7 and then I installed Oracle Enterprise Linux guest OS for Virtual Box. When i open my Guest OS, This Screen Resolution is 800×600 and below.so my screen was very small .So that i plan to modify  screen resolution for Guest OS.

Method 1 : Install Guest Additions

For Oracle Enterprise Linux 5. 

After Started Gust OS at  Virtual Box,  Choose Devices –> Install guest Additions.

It should be appear in guest operating system.

Step 1:


[root@localhost media]# ls

TOSHIBA  VBOXADDITIONS_3.2.10_66523

[root@localhost media]# cd VBOXADDITIONS_3.2.10_66523

[root@localhost VBOXADDITIONS_3.2.10_66523]# ls

32Bit        VBoxLinuxAdditions-amd64.run    VBoxWindowsAdditions.exe 64Bit        VBoxLinuxAdditions-x86.run      VBoxWindowsAdditions-x86.exe
AUTORUN.INF  VBoxSolarisAdditions.pkg autorun.sh   VBoxWindowsAdditions-amd64.exe

[root@localhost VBOXADDITIONS_3.2.10_66523]# cp VBoxLinuxAdditions-x86.run /tmp

[root@localhost ~]# cd /tmp

[root@localhost tmp]# ls

gconfd-root     mapping-root  ssh-ZMDjDI2464              virtual-root.Ob9cyx
keyring-xmJ5Gd  orbit-root    VBoxLinuxAdditions-x86.run  xorg.conf

Step 2: Run x86 VBox linux additions


[root@localhost tmp]# ./VBoxLinuxAdditions-x86.run

Verifying archive integrity... All good.

Your system does not seem to be set up to build kernel modules.
Look at /var/log/vboxadd-install.log to find out what went wrong.  Once you have corrected it,
 you can
run

  /etc/init.d/vboxadd setup
to build them.

You may need to restart the hal service and the Window System (or just restart
the guest system) to enable the Guest Additions.

 Oops :!…….It shows Kernel modules Errors, I just looked and spent some few minutes and fix it, What Errors need, Some Packages Yes.

The Following package need to install , Using rpm -Uvh <package-name>


libstdc++-devel-4.1.2-48.el5.i386.rpm

libgomp-4.4.0-6.el5.i386.rpm

libaio-devel-0.3.106-3.2.i386.rpm

gcc-4.1.2-48.el5.i386.rpm

gcc-c++-4.1.2-48.el5.i386.rpm

Note : You must installed all packages, Otherwise the above Kernel module Errors will be appear. you can get this package from your OEL CD or DVD  /server folder.

After installed Package, you can run


[root@localhost tmp]# ./VBoxLinuxAdditions-x86.run

Verifying archive integrity... All good. Uncompressing VirtualBox 3.2.10 Guest Additions for Linux........

Building the VirtualBox Guest Additions kernel modules

Your guest system does not seem to have sufficient OpenGL support to enable
accelerated 3D effects (this requires Linux 2.6.27 or later in the guest
system).  This Guest Additions feature will be disabled.

Installing graphics libraries and desktop services componen[  OK  ]
[root@localhost tmp]#

Now Guest Additions successfully Installed…. Now I want to set Screen resolution, Unfortunately I rebooted my machine, During Restart It shows some error for Display.I set again old values like “800×600” , After I set it, I started the machine, the old value appear.I thinked Why its not appear Display screen resoltion after installed Guest Addtions.

The answer is , We need to add one line for /etc/X11/xorg.conf        Not Like Ubuntu. OEL some needs.

so I again Startup my vbox X11 setup, [no need this setup, if once your installed Guset additions before reboot, By mistake I rebooted, so the I ran again. you just add one line, its enough ]


#/etc/init.d/vbox-add-X11 setup 

'''''''

After run it, you just go to ADD   “Modes    “1024×768” “800×600″ ” for /etc/X11/xorg.conf


#gedit /etc/X11/xorg.conf

Section "Screen"
  SubSection "Display"
    Depth      24
    Modes    "1024x768" "800x600"
  EndSubSection
  Device       "Device[0]"
  Identifier   "Screen[0]"
  Monitor      "Monitor[0]"
EndSection

Now After Rebooted, Your screen resolution Should be changed. 🙂

——-

Method 2: Without Install Guest Additions, But Oracle Recommand , Install guest Additions.

you can modify from here /etc/X11/xorg.conf

AS a root user,     

Before Copy xorg.conf  

#cp /etc/X11/xorg.conf /tmp

then

Write a new line for xorg.conf

#gedit /etc/X11/xorg.conf

# Xorg configuration created by system-config-display
Section “Device” 
  Identifier  “Videocard0” 
  Driver      “vesa” 
EndSection 

Section “Monitor” 
  Identifier “WXGA+ Inspiron” 
  HorizSync 31.5-90.0 
  VertRefresh 60.0-60.0 
  Option “DPMS” 
EndSection 

Section “Screen” 
  Identifier “Screen0” 
  Device     “Videocard0” 
  Monitor    “WXGA+ Inspiron” 
  DefaultDepth     16 
  SubSection “Display” 
   Viewport   0 0 
   Depth     16 
   Modes “1280×1024” “1024×768” “800×600” “640×480” 
  EndSubSection 
 SubSection “Display” 
   Viewport   0 0 
   Depth     24 
   Modes “1280×1024” “1024×768” “800×600” “640×480” 
  EndSubSection 
EndSection

After modified, you just reboot your Guest OS.

Now you can see your screen resolution.

  1. Dear Azar, I have installed Virtual Box on my Windows 7. And on it I have installed Ubuntu 2 weeks ago. After that, installed Guest Additions, so resolution automatically resized. Did you check install guest additions?
