#11957 closed defect (fixed)

Ubuntu 12.10 sometimes uses VMWare/Gallium, sometimes Humper/Chromium => Fixed in SVN

Description

I'm running Ubuntu 12.10 (64 bit) on Windows 7. Since some time I have a 3D performance problem. Sometimes the 3D performance is very bad. When running glxgears-info I get

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
OpenGL version string: 2.1 Mesa 9.0.3
OpenGL shading language version string: 1.20

After restarting X (may take some tries) I get

OpenGL vendor string: Humper
OpenGL renderer string: Chromium
OpenGL version string: 2.1 Chromium 1.9
OpenGL shading language version string: 4.00 - Build 9.18.10.3071

With the Humper/Chromium renderer the user interface runs very smooth. Also there is an impact on the general performance when VMware/Gallium is used. I think because the virtual CPU has to do the rendering too.

Are you using automatic log-in on the guest, and if so, does disabling it make a difference?

comment:2 by weeman, 11 years ago

I don't use auto login.

Could you apply the above patch to /usr/src/vboxguest-4.2.14/vboxvideo, recompile your guest driver and check if this fixes your problem? In your guest, please do

sudo -s
cd /usr/src/vboxguest-4.2.14/vboxvideo
patch -p0 < ~/diff
/etc/init.d/vboxdrv.sh setup

Then reboot your guest.
