Segfault in Fedora 13 guest when accessing 3d tools -> fixed as of 24-Nov-2010 for 4.0 and later only

[Noel]

I am running Fedora 13 x86_64 (Goddard), fully patched, under VirtualBox (PUEL edition) 3.2.4. (r62467). The Host OS is win7, 64-bit.

# uname -a
Linux myhost 2.6.33.5-124.fc13.x86_64 #1 SMP Fri Jun 11 09:38:12 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux

Within Fedora running Gnome, when I select System, Preferences, Desktop Effects, the program /usr/bin/desktop-effects crashes with a segmentation fault.

This is the backtrace produced by the crash tool Abrt on Fedora:

I initially reported the issue to Fedora but their developers say that the problem lies within the display drivers used by VirtualBox. The Bugzilla ticket is here: ​https://bugzilla.redhat.com/show_bug.cgi?id=603569

After I installed Fedora 13 I patched it, then mounted the Guest Additions DVD and ran VBoxLinuxAdditions-amd64.run. It completed successfully.

I'm having the same issue with Desktop Effects crashing my host. Host is iMac 27" Intel i7 (Snow Leopard 10.6.3) and guest is Fedora13 (2.6.33.5-124.fc13.i686). VBox is 4.2.6. Guest additions seems to be installed properly. I'm getting up to 2560x1440 display size but have reduced it down to 1600x900. Shared Folders works great. Host crashes no matter the screen resolution. But there is a twist. On the same host and VBox, three flavors of Ubuntu 10.04 work perfectly with Desktop Effects. Also a miniMac with Leopard and same VBox and same Fedora13 work perfectly. The iMac has a ATI Radeon HD 4850 Graphics Chip. It's not clear to me exactly where the problem really is. Maybe there is still a problem with the Guest Additions install even though NO errors were apparent. All my Guest Hosts are 32 bit versions.

If you need more info, logs, etc, please ask.

Thanks

Same issue here. I am using gnome but not desktop effects. X server crashes with segmentation fault whenever it tries to start. This is only in virtualbox and started with the latest update of xorg-server.

[hoeferbe]

Same issue here. I have an x86_64 CentOS 5 machine running VirtualBox 3.2.6. (Was 3.16.) The machine has an ATI Radeon HD 2600XT and I use the proprietary drivers. Glxgears works fine on it (the host).

I have Fedora 12 (x86_64) installed as a VirturalBox guest. The VirtualBox guest additions installed successfully. Yet, when I execute glxgears in the Fedora 12 guest, it crashes. The backtrace shows that it, too, has a problem with swrast.c's get_window_size. I submitted a bug to Red Hat in late April 2010, but no action has been taken on it:

My Windows XP guest has no problems with 3D acceleration.

Same issue here. It appears that the system is using Mesa's libGL (which is v7.8) instead of the libGL Vbox uses (v7.2) - that's why this error is occurring.

So does this mean that nobody with Fedora 12 or 13 can get 3D acceleration working?

My Fedora 12 guest is using mesa-libGL-7.7-4.fc12. Ubuntu 10.04 uses ​mesa-libGL 7.7.1. Yet I've seen posts from those users with working 3D acceleration. Why is that?

Thank you for explaining this issue and for any recommendations on how to work around it.

[Ross A]

I just ran glxinfo in gdb and found that the screen->swrast_loader in get_window_size is a null pointer - meaning __DRIswrastLoaderExtension is not initialized in the default private __DRIscreen when it should be. I'm really a novice when it comes to DRI/GLX/Mesa, but I do know that dereferencing null pointers is a bad idea. grep'ing the Vbox source I can't find any file that defines swrast_loader - so I'm figuring it's new to mesa and thus not in Vbox.

Versions of Mesa greater than 7.2 (such as 7.7.4) might play nicely because they use the same struct's and are setup similarly, and are backwards compatible. However, mesa 7.8 might have changed something (like the swrast_loader) which has broken compatibility.

What could fix this is using an old libGL.so that doesn't have the swrast_loader, something that would behave nicely with vbox. I am by no means an expert - but I do know other drivers replace libGL.so with a custom version to get the driver to play nicely with the system (e.g. the nvidia driver). In my Fedora 13 install, libGL.so is the one from Mesa 7.8.1, not one provided by any vbox package - and I'm noticing things don't work right, even for simple GLX applications - telling me libGL.so is not playing nicely with the vbox driver.

Again - I'm not an expert, but that's how the problem looks to me.

I've documented a potential workaround for this problem in the vb forums here:

​http://forums.virtualbox.org/viewtopic.php?f=6&t=32321&p=157027#p157027

In Fedora 13, downgrading mesa-libGL, mesa-libGLU and mesa-dri-drivers from v7.8 to the v7.5 used in Fedora 11 seems to be a good temporary workaround until this bug is resolved.

[hoeferbe]

Update: I've upgraded to VirtualBox-3.2-3.2.10_66523_rhel5-1.x86_64 on the host and updates the Fedora 12's Guest Additions. Still no go.

Thanks! I also read your 2010-10-10 comment about it crashing again after a few days.

I went ahead and tried your work around, anyway, and it didn't work even a little bit. I removed these packages from my Fedora 12 guest:

glx-utils-7.7-4.fc12.x86_64
mesa-dri-drivers-7.7-4.fc12.x86_64
mesa-libGL-7.7-4.fc12.x86_64
mesa-libGLU-7.7-4.fc12.x86_64

downloaded and installed these packages from a Fedora 11 repository:

glx-utils-7.5-0.14.fc11.x86_64
mesa-dri-drivers-7.5-0.14.fc11.x86_64
mesa-libGL-7.5-0.14.fc11.x86_64
mesa-libGLU-7.5-0.14.fc11.x86_64

and then rebooted. Glxinfo still dumps core. I ran "strace glxinfo" and nothing stood out to me except several attempts to open files that did not exist:

/lib64/tls/x86_64/VBoxOGLcrutil.so
/lib64/tls/VBoxOGLcrutil.so
/lib64/x86_64/VBoxOGLcrutil.so
/lib64/VBoxOGLcrutil.so
/usr/lib64/tls/x86_64/VBoxOGLcrutil.so
/usr/lib64/tls/VBoxOGLcrutil.so
/usr/lib64/x86_64/VBoxOGLcrutil.so

Seeing how those are all the same file, I'm guessing glxinfo just looks for that library in several standard places until it finds it. So, the "No such file or directory" errors in the strace are no big deal.

Thanks, Michael! I tested your r68088 of the Guest Additions on my x86_64 Fedora 12 guest and it worked!

I've only tried glxinfo & glxgears. I get about 1,055 frames per second (FPS) from my guest's glxgears. That is about 1/8 what I get on the host. I don't know if that large of a decrease in performance is normal or not, but thought I'd mention it just in case it was not.

I'm just happy that this now appears to be working. Are there any particular tests you want me to run my machine through? Thanks again!

[Michael Thayer]

Replying to hoeferbe:

The best test would be to keep on using those Additions for your day-to-day work with the virtual machine. Apart from that fix they match exactly what the Additions would look like if we did a minor release today, and if we do a minor release in the near future I will prepare a matching "fixed" Additions build if anything non-trivial has changed since now. I am reasonably sure that the fix solves the problem it was intended to, but we would like a bit of testing to be sure that no other 3D-related regressions occur (I don't think they will, but the fix was sufficiently tricky that it is hard to say for sure).

[Nathan]

I have two systems I'm running VirtualBox on. I haven't tested the desktop yet.

The good news is, glxinfo doesn't dump core anymore. The bad news is that now VirtualBox itself crashes completely.

Host OS & VER: Windows 7 Home Ultimate Host GPU: Mobile Intel 4 series CPU: Core 2 Duo (no VT-X support) Guest OS: Fedora 14 32-bit

[Nathan]

I've just tested it with my desktop. It doesn't crash, but it's not 100% either.

Host OS & VER: Windows 7 Pro Host CPU: AMD Phenom II X4 940 (3.0Ghz) Host GPU: NVidia GeForce 8600 GTS Guest OS & VER: Fedora 14 64-bit

+ glxinfo and compiz launch without crashing! + desktop effects seem to work smoothly.

• Window dressing (title bar, close/minimize/maximize buttons) disappears in Seamless Mode. The missing dressing reappears if I exit seamless mode.

After seeing your comments, I quickly installed a Fedora 14 x86_64 guest, taking all the defaults. (For my CentOS5 host system's details, please see my comment above.) Mine didn't crash, but it performed significantly worse than my Fedora 12 x86_64 guest.

Just to recap: running glxgears on my host results in an average of ~8,480 FPS. With the r68088 Guest Additions, I'm able to get 1,055 FPS in my Fedora 12 guest. My test on my Fedora 14 guest resulted in a very disappointing ~200 FPS.

I re-sized my two Fedora guests to be windows on my host and ran glxgears in each at the same time:

CentOS5 host dropped to ~6,640 FPS. (21.7% decrease)
Fedora 12 guest dropped to ~830 FPS. (21.3% decrease)
Fedora 14 guest dropped to ~39 FPS. (80.5% decrease)[[BR]]

First, using glxgears to measure 3d performance ain't the best idea because it's very "simple" in terms of 3d scene composition, and as all other cases with high fps count (>1k) it shifts bottleneck from actual 3d processing to various other sync issues.

Second, 39fps in glxgears means that 99% you don't have 3d acceleration enabled/working. It's most likely Mesa's software rendering, so please try running glxinfo and check it.

I've attached the log from where VirtualBox crashes when attempting to use 3d. When I attach a debugger to the crash, I get this oh-so-useful message:

Thanks for informing me of that. Other than plain-jane use of 3D for games, I'm a newbie in this realm. So what way should I compare the performance of one machine's 3D acceleration to another. Most of the lines outputted from glxinfo mean nothing to me.

You're right:

# glxinfo | grep -i vendor
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
OpenGL vendor string: Mesa Project

That is strange that the Fedora 14 guest is not using the 3D acceleration. The only errors or warnings I see from Xorg are:

(EE) [drm] drmOpen failed.
(EE) VBoxVideo(0): DRIScreenInit failed, disabling DRI.

which I assume to be similiar to what I see in my (working) Fedora 12 guest:

(EE) AIGLX error: vboxvideo does not export required DRI extension
(EE) AIGLX: reverting to software rendering

As far as I can tell, the Fedora 14 guest is using the VirtualBox driver from the Guest Additions:

(II) Loading /usr/lib64/xorg/modules/drivers/vboxvideo_drv.so
(II) VBoxVideo: guest driver for VirtualBox: vbox
(II) VBoxVideo(0): VirtualBox guest additions video driver version 3.2.11

gblues: Could you try updating your host drivers? According to Intel's site ​http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Laptop+graphics+controllers&ProductProduct=Mobile+Intel%c2%ae+4+Series+Express+Chipset+Family the drivers you use (8.15.10.1883) are quite old and there're recent 8.15.10.2226.

That's quite strange, and opengl acceleration wouldn't work as long as this message is in the log. If previous logs wouldn't show smething meaningfull attaching full var/Xorg.0.log might be a good idea too.

[Nathan]

Thank you for the link to the generic Intel drivers. My OEM (Toshiba) hasn't released a matching update, and the Intel driver isn't certified for my particular laptop (both the Intel installer and the Windows Driver Update failed to automatically install it). Since Windows has the driver rollback feature, I took a chance and forced it to install the Intel driver via the "Have Disk" method and the driver installed successfully. So if there's anyone else with a Satellite A505-S6960, the generic drivers work!

With the generic Intel driver installed, VirtualBox no longer crashes when accessing 3d functions, and I can now use compiz similar to my desktop (the hardware performance differences between the Intel GMA and nVidia 8600 GTS notwithstanding). I experience the missing window dressing in Seamless Mode with compiz enabled on both my laptop and desktop systems, pointing to a VB issue rather than a driver issue.

I refreshed the link above. There were no relevant changes between that image and the Additions included in 3.2.12. However we don't plan to include this in released versions of 3.2 as it is too big a change for an existing stable branch.
