MythTV segfaults with nvidia 334.21-2...

I updated to the latest package for NVidia on my myth frontend in the living room, last weekend.
Alas it made mythfrontend fail with a segfault before it even started to paint anything except the themes' background.

Reverting back to version 331.49-1 fixed this. I reverted back to version 331.49-1 on the following pacakges:

  • nvidia

  • nvidia-libgl

  • nvidia-utils

I run lxde on my myth frontend. This does not happen on the workstation that runs KDE upstairs...

Hope this helps anyone with similar issues.

Regards,
Wille

I confirm the issue with the latest nvidia update using openbox as Display Manager. XBMC starts fine, mythfrontend crashes.
Downgrading as described by @wasperen may work but lead to problems with slim not letting me login, therefore I am stuck with XBMC for the moment.

Another workaround is moving libGLESv2 out of the way.

Does This not break anything else? I'll try it out tonight and let you guys know if this works for me too.

So far I didn't remark any issues related directly. but payback image quality is still worse than with previous versions of the driver.

Yes. This works. And I can not realy see any issues with playback image quality...
So this looks like a good work around

Mythvideo seems fine ideed, but in XBMC I get this horizontal stripe in the middle of the screen. Is this related to playback filters? Using VDPAU

I just watched a SD recording with mythfrontend and it has horizontal stripes over the screen too ... i think it started with 334.xx version of the nvidia driver
