"Error: VBoxClient (seamless) failed to start" VirualBox Guest Additions 5.2.7 in Kubuntu 17.10.1

[Cetus]

Hi all,

I have VirtualBox 5.2.6 but am using the Guest Additions 5.2.7 (fixed) which corrects a version 5.2.6 black screen problem after installation (affecting Kubuntu 17.10.1and Linux Mint 18.3, at least).
Another topic here says that turning off 3D acceleration solved that problem but it did not work for me. Luckily, the problem was quickly fixed with Guest Additions 5.2.7

The Guest is Kubuntu 17.10.1 and the Host is Windows 10 Pro x64.

Trying to install the Guest Additions on a clean install of Kubuntu results in an error message that gcc, make, and perl are not installed. This is remedied by

Code: Select all

sudo apt-get install build-essential

However, after what seems like a successful installation, after a reboot this error message is displayed:

Code: Select all

VBoxClient: VBoxClient (seamless): failed to start. Stage: Setting guest IRQ filter mask Error: VERR_INTERNAL_ERROR

Here is the result of

Code: Select all

systemctl status vboxadd*

I know I'm forgetting some info that I need to provide but I can't think what it may be so please ask for it.

Thank you in advance.

Using a tip provided on the Kubuntu forums that the 4.13 kernel didn't work with Guest Additions(?) (or the other way around), which is the first time I've ever heard that one so I can't
really testify as to its accuracy, I have found a partial fix.

I used ukuu to upgrade the Kubuntu 4.13 kernel to the very newest which is 4.14.13. (as of 19Jan2018)

After doing that and re-installing Guest Additions 5.2.7 once again, all the functions worked that I tried, Copy and Paste, Drag-n-Drop, and folder sharing. Yes!

No error messages on the desktop after re-booting and no errors listed in systemctl status vboxadd*.

UNFORTUNATELY, now 3D Acceleration has to be turned off or the system freezes after a few seconds. I thought it was just the GUI of the desktop at first but no key combinations will work after it freezes, either.

If someone can suggest what logs I should check, I will happily post the info here. There is no way possible that I'm the only person experiencing this and I'd like to find a fix to share.

Thanks in advance.
