[SOLVED] How to change monitor resolution

[satimis]

Hi folks,

host - Ubuntu 10.01
guest (VM) - ubuntu 10.01
Sun VirtualBox - virtualizer

How can I change screen resolution?

$ locate xorg.conf

/usr/lib/X11/xorg.conf.d
/usr/lib/X11/xorg.conf.d/05-evdev.conf
/usr/lib/X11/xorg.conf.d/10-synaptics.conf
/usr/lib/X11/xorg.conf.d/10-vmmouse.conf
/usr/lib/X11/xorg.conf.d/10-wacom.conf
/usr/share/man/man5/xorg.conf.5.gz

xorg.conf doesn't existing

System -> Preferences -> Monitor
800x600 max.

Thanks

You just create a /etc/X11/xorg.org file. X will use it.

May also want to take a look at xrandr command.

$ ls /etc/X11

app-defaults             fonts    xinit     Xresources  Xsession.options
cursors                  rgb.txt  Xreset    Xsession    XvMCConfig
default-display-manager  X        Xreset.d  Xsession.d  Xwrapper.config

It is NOT there

Hi Luis


I don't need it. Only for this occasion.

A further question which file will Ubuntu 10.04 use if without xorg.conf?

May also want to take a look at xrandr command.

Whether you meant;

X now detects and configure (or tries to) your hardware every time it runs.
So if it is successful, there's no need for the xorg conf file.
it's not only on ubuntu, I believe.

About xrandr, that's it. xrandr is the relatively recent xorg tool to change configuration on the fly, after X is already running

Start by typing
$ xrandr
and if you see the resolutions you want, see man xrandr and go from there. If it is just "for this occasion", it may be the tool. But, of course, you'll have to learn it.

PS/EDIT: if you install ati or nvidia proprietary drivers, they will create a xorg.conf file.

Hi folks,

Solution found as follow (nothing to do with Ubuntu);

On host
Applications -> System Tools -> Sun VirtualBox

highlight the VM (Ubuntu 10.04)

Settings -> Storage -> Attributes
CD/DVD Device: VBoxGuestAddition.ISO

Boot up the VM.

After login. On console;

$ cd /cdrom
$ sudo ./VBoxLinuxAdditions_amd64.run

$ sudo nano /etc/X11/xorg.conf
to create an empty file. Put following lines on it

Section "Device"
Identifier "VirtualBox Video Card"
Driver "vboxvideo"
EndSection

Section "InputDevice"
Identifier "VBoxMouse"
Driver "vboxmouse"
Option "CorePointer"
EndSection

then run;
$ sudo /etc/init.d/vboxadd setup

You should restart your guest to make sure the new modules are actually used

Reboot the VM

That is ALL. Screen can be resized.
