The ‘binary’ version of audacity supplied by certain distros lacks functionality, due to patent issues, so the best option is to compile it yourself.. For some time, there have been compatibility issues at compile time between the latest released versions of audacity and ffmpeg, on many systems.. For audacity version 2.0.5, on my systems (Fedora 20) the … Continue reading →
There is an article on DevZone that includes a possible Kernel 3.14 patch, from s_molgaard, for driver 331.38: https://devtalk.nvidia.com/default/topic/683534/linux/331-38-on-3-14-rc1-kernel/ The patch format is – apparently – for kernel boot-time patching using dkms, which I don’t use.. So.. I just manually applied the changes shown for nv-linux.h to the Kernel 3.13 patch mentioned in my previous article https://rglinuxtech.com/?p=1032, … Continue reading →
There have been several ‘Kernel 3.13’ patches on various sites for the latest NVIDIA drivers, and I have finally found one that – on my system – actually works, without causing uvcvideo / usb problems (see previous articles..) Thanks to the folks at ArchLinux, the patch can be found here: https://projects.archlinux.org/svntogit/packages.git/plain/trunk/nvidia_3.13_kernel.patch?h=packages/nvidia Be aware that there are other … Continue reading →
Just updated the test system to Kernel 3.14-rc1, and did the usual tests with the latest VMware (10.0.1) and NVIDIA (331.38). VMware compile failed with the VMware version of vmci, but this can be fixed by selecting the kernel.org versions of these modules, from the standard 3.14-rc1 source tree. The vmci module can be found under ‘Misc … Continue reading →
Just updated the DreamPlug and Raspberry Pi to Kernel 3.13.1. DreamPlug kernel from kernel.org, and the Pi from GitHub, as usual..

Installed kernel 3.13.1 on my main system, and found a better version of the NVIDIA patch for driver 331.38 here: http://cvs.rpmfusion.org/viewvc/rpms/nvidia-kmod/devel/nvidia_3.13_kernel.patch?revision=1.3&root=nonfree&view=markup Video playback – especially on kaffeine – is better, but I am still getting problems with uvcvideo and usb audio etc: …….

NVIDIA have just released a new version of their ‘legacy’ 304-series driver – 304.119, but it still needs the usual patch for kernel 3.13.. modprobe: ERROR: could not insert ‘nvidia’: Unknown symbol in module, or unknown parameter (see dmesg) make[1]: *** [package-install] Error 1 make: *** [install] Error 2 Hopefully NVIDIA will release really up-to-date drivers soon, … Continue reading →
Setting up a test system for the usb/uvcvideo tests, I have found another kernel 3.13 issue – this time with Linux as a VMware guest.. The shared folders – which work OK with 3.12, do not work with 3.13. Normally shared folders are found under /mnt/hgfs, but with 3.13 the hgfs directory is corrupted in some odd … Continue reading →
After some problems with uvcvideo / usb under 3.13 producing non-working camera and audio, and producing a ‘tombstone’, I have reverted to 3.12.8 for the time being.. More research is needed, and I have set up a 3.13 ‘guest’ under VMware to conduct further tests, without the ‘kernel taint’ of NVIDIA drivers, etc.. [50677.696508] cannot submit urb … Continue reading →
