After upgrading to Kubuntu 15.04 (via 14.10) from 14.04, I started having new issues with overheating. I have a Dell XPS 13 (Developer edition) with Intel HD4000.
In particular it is now difficult to watch HD videos (e.g. from Crunchyroll.com), whether through Firefox or Chrome. After a couple of minutes, the CPU throttles hard as it gets too hot (verified with sensors), making the video unwatchable. This is not an issue I observed back when I was running 14.04. After reading around, I installed the vdpau libraries, but that didn't help. I then found this issue, and saw that vdpauinfo gave the same error report. I don't know that it is a very good workaround yet, but doing VDPAU_DRIVER=va_gl firefox got me through the video I was watching without throttling (it still got relatively hot though). The suggestion with the ppa above did not work as apt refused to use that repo. To me, due to the overheating, this seems to be a rather critical issue. ** Tags added: vivid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libvdpau in Ubuntu. https://bugs.launchpad.net/bugs/1300215 Title: Failed to open VDPAU backend libvdpau_i965.so: cannot open shared object file: No such file or directory Status in libvdpau package in Ubuntu: Triaged Status in libvdpau-va-gl package in Ubuntu: Confirmed Status in libvdpau package in Debian: New Bug description: This has been bothering me at least since precise (although there the missing link went to libvdpau_nvidia.so which was all the more mysterious since I do not own NVIDIA hardware).
