| #13237 | obsolete | 3D acceleration in Linux/Ubuntu causes UI bugs and system crashes | ||
| Description |
host is windows 7 sp1 x64 laptop with a nvidia graphic chip. guest is a ubuntu 14.04 x64 (guest additions installed). I am using 4.3.12 because there are just too many bugs with 4.3.14, but i can reproduce it in 4.3.14 aswell. Two problems that hit me in the face (there are probably more): 1) QtCreator uses OpenGL in its welcome screen, as a result wired UI bug appear, where the welcome screen is before the rest of the application. Screenshot: https://i.imgur.com/TEDJGdI.png 2) When terminating some opengl application (like QtCreator), it hangs the entire system and i have to do a hard reset(!). To reproduce both problems, download the the Qt5 online installer for Linux x64 and install the default configuration (QtCreator + GCC libaries). Then start QtCreator and observe above defects. http://qt-project.org/downloads Workaround: turning off 3D acceleration resolves both problems. However, that is not an option if one wants to use the Ubuntu desktop. |

| #12513 | fixed | 3D acceleration in Ubuntu 13.10 guest broken - workaround -> fixed as of 11 March 2014, version 4.3.x and later | ||
| Description |
I run Ubuntu inside VirtualBox on a Windows laptop. Until some months ago the 3D acceleration was working fine, which meant that the desktop effects were nice and slick, but something happened, I think when I upgraded to 13.10, and it broke. Very long story shorter - a VirtualBox library was failing to load: From Xorg.0.log: [ 25.572] (EE) AIGLX error: dlopen of /usr/lib/x86_64-linux-gnu/dri/vboxvideo_dri.so failed (VBoxOGLcrutil.so: cannot open shared object file: No such file or directory) I won't pretend that I fully understand what's broken, but it seems that ldconfig can't see the VirtualBox guest additions libraries that are in /opt/VBoxGuestAdditions-4.3.6/lib, which are linked from /usr/lib64/, two of which in turn are linked from /usr/lib/x86_64-linux-gnu/dri/. Partly that seems to be because /usr/lib/x86_64-linux-gnu/dri/ isn't in the ldconfig paths (x86_64-linux-gnu_EGL.conf -> /etc/alternatives/x86_64-linux-gnu_egl_conf references /usr/lib/x86_64-linux-gnu/mesa-egl instead). Also, even if these libs were in the right path for ldconfig, ldconfig doesn't seem to pick them up because their names don't begin with "lib". I've no idea how this worked in an earlier version of Ubuntu, and I don't have time to reinstall an earlier version to find out. For now I've cheated by adding: export LD_LIBRARY_PATH=/usr/lib64 to the end of /etc/profile and rebooted. It's ugly but it has done the trick - 3D acceleration works again, and Ubuntu feels fast again. Confusingly, after this change, the newly-written Xorg.0.log file /still/ contains the AIGLX error line quoted above. However, /usr/lib/nux/unity_support_test -p reports a full list of "yes", whereas before it gave a "no" for "Not software rendered" and "Unity 3D supported". |

| #5047 | obsolete | 3D acceleration is not enabled in 32-bit apps on 64-bit Linux guests | ||
| Description |
When running a 64-bit app on a 64-bit Linux guest, with Guest Additions installed, 3D acceleration is enabled. However, when running a 32-bit app on a 64-bit Linux guest, 3D acceleration is not available for that app. It falls back to the software rasterizer. The 64-bit Linux Guest Additions should enable 3D acceleration for 32-bit apps as well as 64-bit apps. |
