host: Windows 10 Professional

I previously tried this with 16.04.1 with latest HWE kernel (4.10.x) kernel with same results.

I reinstalled an Lubuntu 16.04.1 alternate install ISO keeping the non-hwe 4.4.0-97 kernel with only:

sudo su
apt-get update
apt-get dist-upgrade
reboot

apt-get install mesa-utils

At this point it is still using Ubuntu's pre-installed flavor of the guest additions (5.0.18 Ubuntu). running "glxinfo" doesn't crash.

installed guest additions 5.2.1 r118447 guest additions.
reboot.

lsmod vboxguest
lsmod vboxsf
lsmod vboxvideo

The updated 5.2.1 r118447 additions install correctly (thanks for the quick fix).

However, running glxinfo still endlessly spams the error message: OpenGL Warning: vboxCall failed with VBox status code VERR_BUFFER_OVERFLOW. Note, that on the other thread someone mentioned seeing the same message on the console.

If I press Control-C once the warnings stop. But I must press Control-C again to exit back to the command prompt.

I shut down the guest with the "shutdown" command and attached the log. Please let me know if any other info is requested.

Fyi, disabling "3d acceleration" makes glxinfo not give any errors.

I also tried 5.2.1-118452 guest editions and it has the same problem.

same problem, Vbox / extensions / guest pack all version 5.2.1 r118918

Same Problem with Linux Mint :

4.10.0-38-generic
16.04.01. Ubuntu

I don't know anything about the virtualbox code under the hood...

But it looks like the "OpenGL Warning: vboxCall failed with VBox status code VERR_BUFFER_OVERFLOW" warning is generated from one of these two places:

https://www.virtualbox.org/browser/vbox ... vboxhgcm.c
line 601

https://www.virtualbox.org/browser/vbox ... boxhgsmi.c
line 279

The non-working "Black screen login" Ubuntu problems are stuck at 100% cpu spamming the same error. So my guess is that fixing this may fix that one as well...

Same problem here.
VirtualBox 5.2.2-119230-Win (Qt5.6.2)
Ubuntu 16.04.3-desktop-amd64 (clean-installed)
GA 5.2.2 iso dated 2017-11-23

Desktop login is broken after GA installed. After login, ~/.xsession-errors is spammed with the "OpenGL Warning: vboxCall failed with VBox status code VERR_BUFFER_OVERFLOW" warning.

ALL: Please see the Note in the Downloads section (https://www.virtualbox.org/wiki/Downloads).

Thank you!

Guest additions 5.2.3-119611 fixes the problem.

Just an update...

5.2.3-119611 guest addition fixes the endless-spamming of "VERR_BUFFER_OVERFLOW"

... but

I notice when I run glxgears or glxinfo I still get *one* "VERR_BUFFER_OVERFLOW" warning at the very top of the output?

Just an update

glxinfo >/dev/null

On two different Linux hosts (Lubuntu 16.04 and Lubuntu 18.04 beta) I got no errors with VirtualBox 5.2.6 + 5.2.7 guest additions.

But on Windows 10 host with VirtualBox 5.2.6 + 5.2.7 guest additions with an Lubuntu guest I still get *one* VERR_BUFFER_OVERFLOW right at the start of running glxinfo/glxgears.

5.1.x had no such errors.

Is there any other diagnostic I should provide?

Thank you,

follow up:

5.1.32 host with 5.1.33 guests has no VERR_BUFFER_OVERFLOW error..

It's only the 5.2.x series so far in my testing.

I'm having the same problem on a Windows 7 host with Ubuntu 16.04 with Guest Additions 5.2.8
