IT might be NVidia driver problems. I have been having all kinds of problems with a Lenovo t510 since day one. (discreete Nvidia NVS3100M). Could never figure out what the problem with this machine was.. (running Windows 7 64 Ultimate).
Trying Ubuntu 14.04 on this machine now and I am having problems with the audio (also Nvidia). The speakers just shut off after 10 minutes, but there is audio out the headset jack, so the laptop is plugged in an external. speaker. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331-updates in Ubuntu. https://bugs.launchpad.net/bugs/1401355 Title: package nvidia-opencl-icd-331-updates (not installed) failed to install/upgrade: trying to overwrite '/usr/lib/i386-linux-gnu /libnvidia-opencl.so.331.113', which is also in package nvidia-opencl- icd-331 331.113-0ubuntu0.0.4 Status in nvidia-graphics-drivers-331-updates package in Ubuntu: Confirmed Bug description: There was an update of the driver this morning; since then I have been having difficulties with my CUDA code.
