Public bug reported: Hello,
1) lsb_release -rd gives Description: Ubuntu 10.04 LTS Release: 10.04 2) apt-cache policy nvidia-current gives nvidia-current: Installed: 195.36.15-0ubuntu3 Candidate: 195.36.15-0ubuntu3 Version table: *** 195.36.15-0ubuntu3 0 500 http://us.archive.ubuntu.com/ubuntu/ lucid-updates/restricted Packages 100 /var/lib/dpkg/status 195.36.15-0ubuntu2 0 500 http://us.archive.ubuntu.com/ubuntu/ lucid/restricted Packages fber...@xanth:~$ apt-cache policy nvidia-current nvidia-current: Installed: 195.36.15-0ubuntu3 Candidate: 195.36.15-0ubuntu3 Version table: *** 195.36.15-0ubuntu3 0 500 http://us.archive.ubuntu.com/ubuntu/ lucid-updates/restricted Packages 100 /var/lib/dpkg/status 195.36.15-0ubuntu2 0 500 http://us.archive.ubuntu.com/ubuntu/ lucid/restricted Packages 3) I expected BuGLe do work in direct rendering mode and returning the right OpenGL versions and extensions. 4) Here is what happen: I'm using BuGLe to debug OpenGL programs under Linux: http://www.opengl.org/sdk/tools/BuGLe/ So far it was working great with Ubuntu 9.10 (coming with nVidia driver 185.18.36). After an upgrade to Ubuntu 10.04 (coming with nVidia driver 195.36.15), I have the following wrong behavior: When the OpenGL calls are intercepted by BuGLe, the driver runs in indirect rendering mode and falls back to OpenGL 1.4. With Ubuntu 9.10, the driver used to properly run in direct rendering mode with OpenGL 3.0. $ gldb-gui glxinfo &> output.txt direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose) OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: Quadro FX 3600M/PCI/SSE2 OpenGL version string: 1.4 (2.1.2 NVIDIA 195.36.15) [the complete output is in the attached file output_gbdb- gui_20100508_glxinfo.txt] Not using gldb-gui, I get what I expect from glxinfo: $ glxinfo direct rendering: Yes OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: Quadro FX 3600M/PCI/SSE2 OpenGL version string: 3.2.0 NVIDIA 195.36.15 OpenGL shading language version string: 1.50 NVIDIA via Cg compiler [the complete output is in the attached file output_glxinfo.txt] PS: here are the straightforward steps I use to install BuGLe: $ export CFLAGS=-U_FORTIFY_SOURCE (required under Ubuntu) $ tar xjvf bugle-0.0.20100508.tar.bz2 $ mkdir bugle-build $ cd bugle-build $ ../bugle-0.0.20100508/configure --without-lavc $ make -j3 $ make install I already discussed with nVidia staff and the BuGLe developer. The nVidia staff says that the Ubuntu package relocated some files that probably confuses BuGLe. They try BuGLe on Ubuntu 10.04 with the Ubuntu package and from the nVidia installer itself. BuGLe is working fine with the nvidia install but not with the Ubuntu package.
