Same problem (assumed) here with Kubuntu 16.04, and Kubuntu 17.10. Nvidia 384.90 video drivers.
Seeking in large files causes VLC to hang freezing the desktop session. Sometimes I can CTL-ALT-F2 and get a console session. VLC cant be killed, wont even die with a -9 for several minutes. Sometimes I cant even CTL-ALT-F2 to a console. Graphical console is completely frozen. I can ssh in, which leads me to believe that the problem is not that the entire system is frozen, just something in the video side. Ive tried every setting in VLC I can from disabling hardware acceleration, use/dont use VDPAU, etc.. Other video players which do use HW Acceleration seem to have no issue. The larger the file, the more I seek/skip, the more likley VLC is to trigger the freeze.
