Hello all,
I have a Dell E5520 laptop which is a pretty generic i5 with HD3000 graphics, however I have a high res screen with 1920x1080 resolution. I think my problem may be related to this high res screen. My laptop is running Windows 7 x64. I am running VB 4.1.16 but I have had this problem ever since the Gnome 3 distros started to appear, my laptop is about 1 year old.

My problem is I cannot run any of the newer Linux flavors that use Gnome 3 in fullscreen mode. I can run them in a maximized window which is almost full screen, but not fullscreen. When I try, the mouse pointer and the objects on the screen no longer match, and screen updates are horribly slow. I can switch in and out of fullscreen mode usually without trouble. In a maximized window, 3D performance is very good. Also, I am able to resize the window to just about any size I want and have seen no problems with any size. Running in a window seems fine, but fullscreen just does not work. Also, if I disable 3D, then I can run the Gnome 3 versions in fullscreen, but they revert to a much simpler desktop.

Here is what I find interesting. I can run KDE based distributions (OpenSUSE, Kubuntu), Xfce based (Xubuntu) in fullscreen with 3D no problem. I can run Gnome 2 based distributions also with 3D no problem. I can run the new LinuxMint 13 Mate version (fork of Gnome 2) with no problem. But the newer Gnome 3 based distros will not work in fullscreen. Currently, Linuxmint 13 Cinnamon and Ubuntu 12.04 (both Unity and pure Gnome 3) suffer from this issue.

In all cases I have removed any included versions of guest additions and added them directly without success.

I have tried looking for an updated Intel HD3000 driver and indeed there are newer ones but they cause a complete failure of Virtualbox if 3D is enabled (a whole other can of worms). So for now, I am using the most recent Dell approved driver.

I am attaching a log file. The session was started in maximized window, changed to fullscreen then back and shutdown.

Does anyone have any ideas as to what might be going on? Is it my 1920x1080 screen? By the way, my desktop machine has 1920x1200 and the same OS versions work fine in fullscreen mode on it, so I don't think it is the raw pixel count.

Thanks in advance.

Hi, I have moreorless the same configuration (Dell 5520, but i7 quadcore, same graphics, same FHD display, running Win 7 as host and Ubuntu 12.04 as guest in virtualbox). And, the same problem. But I was running Gnome 3 in full screen without problems in Ubuntu 11.10; after I upgraded it to Ubuntu 12.04 it was still working fine. The slowness only appeared after some updates from May. What is even more weird is the the slowness only occurs typically only to the 2nd reboot of the virtual machine: so I start ubuntu in virtualbox, it is slow, I shut it down and reboot it, it works, after next reboot it is still slow etc.

Ditto here. Both of my Ubuntu 12.04 and Linux Mint 13 VMs fail as described above.

My machine is a Lenovo X220, Intel HD Graphics 3000, 1366x768 resolution screen, Win 7 x64 host, VBox v4.1.16, fully updated Guest Additions. Maximized window works fine, when set to fullscreen, the symptoms are the same.

Hoping for a solution...

Thanks for chiming in. At least now I know I am not the only one.

Curious, is it worth filing a bug? With the number of open bugs, I wonder if it would get any attention.

For anyone else suffering from this problem, it appears there is already an open bug for it, #8858.

Hi, new guy here! I've been using an Asus N55SF (I7 2ndG quad core/Win 7 pro), I have been having pretty much the same problems, but with with Linux Mint 13, I have found a partial work around though. If like myself you have dual graphics processors (ie onboard/intel and dedicated), it may be possible to fix this problem though not properly...

My laptop has both integrated Intel graphics and dedicated (GT555M) graphics processors. It is possible, through the Nvidea tray icon (manage 3D settings), to choose which graphics processor Virtual box uses. Simply click add, and navigate towards the Virtualbox exe. I have found Linux Mint 13 runs almost correctly...

There are a couple of notable caveats... Firstly, I could not access the bottom of screen menu for the VM. Secondly, if I use host+F, the VM stops responding, and I have to close and reboot. If I ctrl+alt+del and select task manager, I can access the desktop of my host OS with the show desktop shortcut. I can then return to the VM and resuse where I left off. It is worth pointing out that I had to disable screen lock in the VM, as this was also causing issues.

This isn't a perfect solution, but it is a usable workaround, until they patch this bug.
