Linux-on-Windows 3D support slow, buggy and generates lots of errors

[memoryhole]

I'm running a Ubuntu 14.04.3 LTS guest inside VirtualBox 5.0 (with up-to-date additions) on Windows 7 Enterprise (64-bit) host. When 3D acceleration is enabled, screen redraws are slow and often do not refresh blocks of the screen correctly. For example, flipping through a multi-page PDF often results in half of the page not being redrawn. Also, sometimes the terminal (xterm) doesn't redraw when executing a command, giving the illusion that it didn't execute. Moving the window or scrolling will typically restore the contents of the window to what they should be.

Further, when I run the unity_support_test program, I get a lot of OpenGL warnings. In particular:

$ /usr/lib/nux/unity_support_test -p

As you can see, it thinks 3D acceleration works, and it's using the Chromium driver, but could not load the vboxvideo driver and as a result, the 3D accelerated behavior is flaky at best (per the description above).

The workaround has been to disable 3D acceleration and switch to a non-Unity desktop (for speed).

[memoryhole]

I noticed that 3D acceleration doesn't have the same issues when using a non-Unity (i.e. non-3D) window manager. I can re-create the redraw issues when I log in with the default Ubuntu Unity desktop, but when I log in with the legacy Metacity desktop (still with 3D acceleration enabled), the redraw issues cannot be replicated (or at least, are very hard to replicate).

Looks like VirtualBox-5.0.3-102322 fixed at least the redraw issues on my system (openSUSE 13.2, kde4, qtcreator >= 3.4 did not redraw it's contents now and then) but the error that vboxvideo could not be loaded still exists:

That error is actually cosmetic and due to the rather hacky way we handle 3D currently on Linux guests.

[petersv]

Still present with virtualbox 5.0.10 and corresponding guest additions.

I don't think that this will get fixed in a stable release in the near future, but I have been playing a bit with 3D in the development branch, so if anyone would like to try out the latest code and see if anything works which didn't before, here is a test build:

Hi Michael, above file does not exist anymore (and i guess is now also a bit dated). Is there by chance an updated version of this and/or any hope that a fix would despite your warnings might make it soon into a stable version?

[Michael Thayer]

Here is a new link:

https://www.virtualbox.org/download/testcase/VBoxGuestAdditions_5.0.51-105459.iso

A slow overhaul of Linux and X11 graphics has been taking place for a while. The most recent changes have been to replace the user space X11 graphics driver by a kernel one, which is included in the build linked above. Once the 2D overhaul is done (soon I hope) the 3D work can begin, but it will be a long process due to lack of developer time. There are no volunteer contributors helping on this, though it would probably be an interesting challenge for me to efficiently co-ordinate their and my work if there were.

Replying to michael:

Hi Michael, thanks for the update. I gave it a quick shot but for some reason after installing it and enabling 3D i got only 1024x768 as maximum resolution .... :-(

PS: my host is windows 8.1 on a hp 840 G2 (with intel graphics) and guest is Ubuntu 15.10 ..)

[Michael Thayer]

Could you please attach the guest's system and X.Org logs?

[g2flyer]

Replying to michael:

Could you please attach the guest's system and X.Org logs?

Guest ist Ubuntu 15.10 (32-bit); for logs find attached three versions: 2 with your guest additions, run once with and once without 3D enabled and a third one with the 5.0.14 guest addition and 3d disabled. Looking at log it seems it cannot load properly your module and resorts to VESA, hence the 1024x768?

As a side-note, maybe or maybe not relevant: i usually run VirtualBox on an external monitor of 1920x1200 (with my laptop having 1920x1080) and even with 5.0.14 i have a strange issue: when I start it in fullscreen it always wants to disply in 1920x1080, not 1920x1200, and for some reason i cannot really change it with xrandr properly; i have to kill/restart unity to get it working properly. Probably/maybe completely unrelated to the VESA issue but thought i mention it ..

[Michael Thayer]

Could you please attach the guest's system log too, and /var/log/vboxadd-install.log from the guest after installing the 5.0.51 Additions?

[g2flyer]

Replying to michael:

Find attached kern.log and syslog during the time of the three runs mentioned in the previous comment plus guest-install logs for both standard 5.0.14 and your 5.0.51.

[Michael Thayer]

You did not attach a log file for the virtual machine, but I am guessing that you have allocated a lot of video memory (by the way, for Linux guests there is currently no benefit and a few disadvantages to allocating more video memory than you need for your virtual desktop. That may change at some later point.) If I am right, could you see if reducing it helps?

Regarding VRAM, i did attach the maximum 128MB (i was previously experimenting with two monitors and there i run out of RAM when having considerably less: i (vaguely) think originally i had 32MB or alike ...). Can give it a shot (although nothing in the log-files seems to indicate that the problem is too much VRAM?)

Sorry, missed the part about the VM log. Will attach it when i have time to run an experiment with less VRAM ..

[Michael Thayer]

We generally ask bug reporters to provide logs, but I also definitely failed to remind you to do so up until now.

[Michael Thayer]

g2flyer: I was unable to reproduce this by increasing video memory to 128MB on my Ubuntu 15.04 virtual machine. Since this seems to work for a lot of people, perhaps you could do some experimenting if you are interested in getting this resolved to find out more about what the trigger is.

In case you need it, here is more or less the most recent build:
