I installed Ubuntu 24.04 LTS inside a Virtual Box on a new Windows 11 host. Clicking on the File Manager on the Desktop (or on related buttons like trash bin or CD) does not show a normal window but just some colored stripes, sometimes blinking. A screenshot is appended. Other applications (terminal, software center, firefox, ...) run without any problem. Can anybody please give me a hint, where this problem may come from?Screenshot after clicking file manager

  • Have you installed the guest additions? Commented May 10, 2024 at 20:20
  • Yes I did. One problem is that I do not remember how ;.) I followed an instruction saying click on the disc symbol, then do this and that. Now as I said thefile manager also failed for the CD and did not show the directory. So I played around with the graphics driver and the 3D acceleration and the like and finally I was in a state where I could see the contents of the CD and complete the installation. Of course I thought that now my problem was solved but it wasn't. Commented May 10, 2024 at 20:30

    So you probably didn't install and what you¡re seeing now is a consequence of "playing around". Virtualbox's guest additions for Ubuntu are in the Ubuntu repositories and should be installed from there. Commented May 10, 2024 at 20:43

It looks issues of GTK4. A work-around is shared here: https://gitlab.freedesktop.org/mesa/mesa/-/issues/11008

  • The suggested solution was to add export GSK_RENDERER=gl to the .profile or another login script. This did the trick for the file manager, thanks a lot! However, the problem persists for emacs which I use a lot. Is the renderer application specific and if so, how do I set it for one particular application like emacs? Commented Jun 18, 2024 at 14:29
  • I have upgraded my video memory from 128MB to 256MB and also enabled 3d acceleration after installing which I THINK caused the issue. So I reverted it back to 128 MB in video memory and disabled 3D acceleration in Virtual Box, rebooted vm and it's fixed. Commented Jul 6 at 19:50

I got exactly the same issue. Some more details on what happens on my configuration:

  • Host OS is Windows 11 and Guest OS is Ubuntu 24.04.1
  • VirtualBox version 7.1.4 (and guest additions 7.1.4 too)
  • Creation of a new ubuntu VM only possible with VBoxSVGA driver (otherwise installation does not start and displays an error). I select VBoxSVGA without checking the "3D acceleration" option
  • apt update & upgrade
  • apt intall build-essential dkms
  • Install guest additions in CDROM
  • run VBoxLinuxAdditions.run

With this configuration, File Manager displays correctly, but I cannot redimension the virtual screen. If I stop the machine, select VMSVGA instead and restart: I can redimension the screen, but File Manager does not display. The process is repeatable
