Hello, I downloaded the latest version of URSim and the latest version of Virtual Box, per the instructions on the UR website. Here’s the problem. I can’t see half the URSim application on the virtual screen, and Virtual Box will not allow me to resize the screen resolution. It is set at 800x600, which is much too small, as you can see in the attached picture. I can scale the screen (100%, 150%, 200%, etc) but this only makes everything bigger proportionally, not fixing the problem. ![Capture](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/9/90aa3d109e33d64364956c8c1f7bd41bdfde2c30.png) The host computer is a Dell Precision M6700 running Windows 7, 64-bit. The virtual machine is Ubuntu, 64-bit. The graphics controller is VMSVGA. If I select any other option, it automatically turns back to VMSVGA. VirtualBox is version 6.1.22 r144080 URSim is version 5.10.2.106319 ---

I think I may have answered my own question. Looks like this is a problem with running Lubuntu on a virtual machine. This tutorial solves the problem: > **[Lubuntu Tutorials](https://lnbu.jimdofree.com/turorials/lubuntu/set-screen-resolution/)** > > When Lubuntu is installed in a virtual machine, the screen resolution always goes back to 800x600 after rebooting. This is a minor issue which is easily corrected. This short tutorial will show you how to make the desired screen resolution permanent.... Basically, I changed the file: ~/.config/lxsession/Lubuntu/autostart by adding the line: xrandr -s 1440x900 -r 60 where 1440x900 seems to be the best resolution for my display. Saving this file and rebooting the virtual machine solved the problem. ---

Thanks for this, I have the same problem. Sorry if this seems like a stoopid question, but when I open the Autostart file it is empty. Is that normal (new install of VM)? ---

It was the same for me. I think it’s supposed to be empty to start. ---

That worked. Thank you! ---

When I’ve experienced this, its been becuase the auto-resize guest display option hasnt been enabled. You can find this in the “view” options in the top bar of the virtual box, after selecting auto resize, then try full screening the virtual box again and the guest window _should_ automatically resize. ---

This only happens to me when I select Insert guest additions CD image and run the VBoxLinuxAdditions.run file, to allow shared folders to work (Doesn’t out of the box!) Somehow this resizes the screen resolution and prevents the above fix from fixing the issue. So I can either have a fresh install where file sharing doesn’t work or file sharing works but the screen resolution is to low and unusable. ---

I was actually able to get both the screen resolution and file sharing to work by following the above-referenced pdf to a tee. I think one of the key parts is under Settings \> Display \> Screen, Graphics Controller should be set to VBoxVGA. This is not the default, but it works. Also note, if I try to Enable 3D Acceleration, I get a lot of crashes. ---

With me and some of my colleagues it is the same. The tip above (autostart file) did not help me alas (or maybe I did something wrong). Sometimes it seems to help to go down to version 5 auf VirtualBox. It is all very strange and cost me a lot of nerve. Is there any plan to update / improve the URSim download file so it properly works with shared folders? ---

> [@kwissing](#): > > VBoxVGA Thank you for the anwer. I solved using VBoxVGA in the settings menu of the VM. After some hours of hard workind ;D
