[mythtv-users] MythTV and Wayland

[John Pilkington]

I just did a quick search on this without finding much.

For years I have been running mythtv master in Fedora KDE X11 with a 
cheapo nvidia GT 710 card, mainly to get an HDMI output, using the 
rpmfusion build of the closed-source 470xx driver.  That driver will 
lose support later this year and its latest version is not yet available 
in rpmfusion.

A few weeks ago after a kde update I started getting usually-brief 
pauses with notifications of graphics resets in Kwin, and the kde-fedora 
list suggested switching to the reverse-engineered nouveau driver, with 
the possibility that this might also work with Wayland, the 'coming thing'.

I now have MythTV master running with nouveau in the Plasma-X11 
environment, although I haven't yet tried using VDPAU acceleration or 
deinterlace;  it works and suits my use case.

But Wayland isn't as good.  mythfrontend says VDPAU isn't available, 
the menu screens show ghosting, the HDMI TV screen needs a new login 
after it times out or is power cycled, and the (deprecated) mythtv-setup 
crashes on exit.

I'm not sure whether these are 'known unknowns' or just unknown.  Are 
they worth an 'issue' ?
