Virtualbox GUI

Post by JW8888 »

Hi,

I have been using Virtualbox on Xubuntu in both headless and GUI mode, however, possibly after recent system updates, I cannot start GUI of virtualbox management window or a VM gui. Headless mode can report that a VM is running, and I can save, start, pause a VM, but it doesn't appear to be working properly as I should be able to interact with the headless VM but cannot.

System:
Xubuntu - 16.04.4 LTS (GNU/Linux 4.10.0-42-generic x86_64)

Virtualbox - 5.1.34-dfsg-0ubuntu1.16.04.2
If i try to start virtualbox from command line, I get:

Code: Select all

screen 0 does not appear to be DRI2 capable
screen 0 does not appear to be DRI2 capable
Segmentation fault (core dumped)
or:

Code: Select all

Qt FATAL: QXcbConnection: Could not connect to display 
I have tried total removal of virtualbox and reinstallation, but no difference in results.

Any help much appreciated, thanks!

I suggest you attach a zip file containing the two log files: one normal start that works, and a headless that fails.

Is 3D acceleration enabled for this guest? If yes, try disabling it. Please reply with your results.

vmlogs.zip
2 logs, 1 for headless & 1 for GUI
(23.6 KiB) Downloaded 12 times
I can't check if 3d acceleration is enabled as I can't open the GUI management window and I don't know how else to check... can it be checked/switched from command line??

I have attached log files
one normal start that works, and a headless that fails.
just to clarify: the headless start seems to run, or at least reports that it does from command line state check, its the GUI that fails

running

Code: Select all

virtualbox
on command line gives:
screen 0 does not appear to be DRI2 capable
screen 0 does not appear to be DRI2 capable
Segmentation fault (core dumped)
Thanks again for your help

VirtualBox VM 5.1.34_Ubuntu r121010 linux.amd64 (Feb  2 2018 12:27:46) release log
It looks like you're using the distro's fork version of VirtualBox. You can either ask in their forums for help, or completely remove/uninstall/delete/purge their version and install the official version from the Downloads section of VirtualBox.

If that doesn't work you should try the latest test builds, especially with all the Spectre/Meltdown patches coming in from all sides.
