So I installed LUbuntu 11.04 on my VirtualBox. I couldn't find the 1366x768 resolution so I installed Guest Additions but it wasn't there.
So I used this code to set the correct resolution:

gtf 1366 768 60

xrandr --newmode "1368x768_60.00"  85.86  1368 1440 1584 1800  768 769 772 795 $

xrandr --addmode VBOX0 1368x768_60.00

xrandr --output VBOX0 --mode 1368x768_60.00

The problem is that I can't find a way to save this information for the next reboot. I tried on .xinitrc and nothing happens. Then I tried on .bashrc but it's not working, I need to start a console before this commands are executed.

I was trying to change the default resolution of LXDE on Ubuntu (LXDE is also used in Lubuntu) and I found a solution for this problem. I also have Lubuntu installed and I've checked that this file actually exists which it does (Ijust tried this fix as well and it worked).

So, the fix....

Open up a terminal, press ctrl+alt+t

I'm guessing you have a default Lubuntu install, so "Leafpad" would be your default editor, type/copy this into the terminal and press enter... (you may be asked for a password)
```
sudo leafpad /etc/xdg/lxsession/LXDE/autostart
```

Now add your commands to the bottom of the file adding a @ before the actual command. Mine looked like this after...

@xscreensaver -no-splash

@lxpanel --profile LXDE

@pcmanfm --desktop --profile LXDE

@/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1

@xrandr --auto --output DVI-1 --primary --mode 1680x1050 --left-of DVI-0
