Anybody can guide me how to correct this problem?  thanks

I've recently installed Ubuntu on Oracle's Virtualbox.  Now I want to install the guest additions.  I started up my Ubuntu guest OS, clicked "Devices" and chose "Install Guest Additions". Nothing happened, and I don't see the CD icon on my desktop.  How can I make this work?

I already know how to do it on Mac OS X (plenty of instructions online).  But is it possible to do it on Ubuntu? If yes, how?

I installed  on VirtualBox. I logged in, installed VirtualBox additions and restarted the system. The system did not load again, instead I see this:    The aspect ratio of the image is preserved in this screenshot and it doesn't make much sense to me - no screen has such dimensions. I did not do anything else special that I could mention. This is the only thing I see before the screenshot above:

I was using 13.04 as a guest OS on my VirtualBox 14.2.18. Host is Windows 8. After upgrade to 13.10 Ubuntu does not start. I can see a black screen and blinking cursor. I am pretty new to Ubuntu. I suspect a problem with graphics drivers. I can access tty and all files (/home) are there.

Today I installed Ubuntu 14.04 on my computer. I have dual monitor setup, and they work perfectly when I'm logged into the operating system. But every time I have to login in the login screen, the screens get reversed. And what I mean is that instead of moving the cursor on the main screen to the left to move on the secondary screen, I have to move it to the left side. After login it changes to normal.   Any suggestion would be helpful.  Graphics: NVidia GTX275. Latest drivers installed.

My laptop has a 15-inch 4k display. Almost everything works perfectly, but some applications don't scale and are too small to use. Some examples: Hipchat, Ardour, Steam, Gimp, etc.   Is there a way for me to solve this? I've seen to use xrandr to set DPI before running the app, but that seems to have no effect (or I'm doing it wrong.)  If I could fix this one problem I'd have everything working perfectly.  Also, I'm using Gnome, but the issue was the same in Unity.

I have a Dell Inspiron 1525 laptop and I am planning on purchasing a mac mini, new version , I am tight on money for a while and want to use my current laptop screen as monitor for mac mini, I just want to know if it is at all possible to do, I have windows 7 and ubuntu 11.04 installed in my laptop, and I don't really care if need to wipe them out, or purchasing a monitos is the only option left, also I am planning to use it for coding and stuff, so VNC is probably not a good choice.

My Mac doesn't recognize my TV's resolution on (so far) 3 VGA cables I've tried but it works just fine using other seemingly old VGA cables. My roommate had the same experience on Mint Linux.  What's the difference between VGA cables? What should I look for in a VGA cable that I buy? Are those still being made?

I have a Late 2011 Macbook Pro 13" (running Lion - OS 10.7.4) which I use with a dual external monitor setup. I have two 21" LCDs that I use as external monitors. One uses the built in Mini Display Port on the Macbook Pro and the other is connected via a USB to DVI adapter (Diamond DVILink).  The problem I am having is with the 13" built in display of the Macbook Pro. I would like it to remain closed and unused (I prefer the dual monitors at same resolution), however I cannot seem to "disable" the display in the display preferences applet. So even though the Macbook Pro lid is closed the operating system still makes use of the display, even though the apple logo on the back of the display is unlit. I have tried to move the laptop screen off out of the way in display preferences but I find when I "sleep" my setup that any applications that remain open move to the laptop screen. This makes it difficult to locate the application windows when resuming from sleep.    Does anyone know of a way to disable the laptop built in display so it is not seen by the OS when external monitors are being used?

Yesterday I was trying update my OS from 12.04 to 14.04.  This was done in my VirtualBox. I left the terminal open and continuing downloading during the night.  This morning when I came to my office, I saw the screen of my VirtualBox Ubuntu was deadlocked, I can't do any operation to it, it stays at some chromium interface I viewed last night.   So I forced restart it, and then I found I was enter into the interface of 14.04 . After I logged in, several error box popped out. But after I installed VirtualBox GuestAddtion package. No more error box popped out when I enter the GUI at the recently log-ins.  But I was still worried about if there may be some lethal bugs left when updating, at least it wasn't ended at an normal way.  So, is there a way that I can check if my update was complete?

I am trying to install Guest Additions in VirtualBox with Windows XP host and Ubuntu 12.04 guest. I followed the above steps:  Devices-&gt; Insert Guest Additions CD Image. After that I locate the folder /media/VBoxAdditions4.3.4_91027/ and run sudo ./VBoxLinuxAdditions.run   I want to be able to create shared folders and adjust the resolution of the screen. I achieved to do the first issue, but I couldn't do the second one. I didn't get any message, however it is not possible to change the resolution of the screen and I cannot switch to fullscreen. What am I doing wrong?  I found in the instal log the following message: unknown version of the X Window System. I've tried the solution of the proposed link but I got the following message:  Building dependency tree        Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

I tried also to install with the command sudo apt-get install virtualbox-guest-dkms but nothing is changing. During the installation of dkms I got the message: Error!

Is it possible to convert a Physical Ubuntu Install (Intel based PC with Ubuntu 10.10) to a virtual box disk, so that I can use that same environment on a separate pc or can keep it virtual for testing?  Something similar to "Disk2VHD" which converts a physical Windows 2K3 and above box into a VHD or VMware image.  Will be grateful for your assistance ! Kind Regards

I have a MacBook Pro (13-inch, Mid 2012) and would like to set up two 24" Acer monitors so I can have an easier working life. The monitors support CDMI, DVI and VGA, I am new to MacBooks, so I'm not sure where to go or what to do, anything you can advise will be wonderful.  Thanks in advance :)

I am using Nvidia graphics card. I run Ubuntu 16 on virtualbox. Host OS is windows 10. Does it make sense to upgrade the graphics driver in my Ubuntu image running on virtualbox? My CPU also support integrated Intel Graphics.

I use a Full HD 24" external display besides my 15" MacBook Pro Retina, on which I use the option for most screen estate regarding the Retina display. In the display arrangement screen, the MacBook Pro is therefore a bigger rectangle than the external display. Is there a way to size these rectangles regarding their "real world size" instead of resolution? I'm annoyed by my cursor teleporting vertically whenever I move from one display to another.

How can I adapt Ubuntu to a high resolution display?  I have a display with 3200x1600px on only 11'' and everything looks really tiny.
