X freezes after seeking x264 file in VLC on Linux v4.14.8 with NVIDIA v387.34-14 with GeForce GTX 960

Hi!

I’ll follow up with the full NVIDIA debug log once I’ve gone through its contents, but looking to see if anyone else has experienced this issue. Have had the card for a year and its been working fine under Windows 7. On Linux, however, seeking in VLC seems to freeze X (assumed because windows aren’t responsive and keyboard events get queued). SSHing in and kill -9’ing VLC clears it right up. This on Arch Linux with everything up to date and has been the case for 2 months now.

Kernel logs only a single error 31 when it happens:

[Tue Jan  2 20:52:24 2018] NVRM: Xid (PCI:0000:0e:00): 31, Ch 00000039, engmask 00008100, intr 10000000

VLC, however, is slightly more verbose:

VDPAU nvidia: Version: NVIDIA VDPAU Driver Shared Library  387.34  Tue Nov 21 02:08:49 PST 2017
VDPAU nvidia: Error detected 0 8273

It’s fairly consistent, even though sometimes takes a minute of aggressive seeking in VLC to freeze it up.

Thanks in advance!

Seen also with MythTV’s mythfrontend when exiting video playback, same freeze behavior as OP.

nvidia driver is 384.111
