[mythtv-users] Incorrect Refresh with Nvidia 361.28 - Long

[Mark Goldberg]

On Mon Feb 22 2016 you folks said:

>May not be involved, this should have been solved years ago but.. In the
past the randr? extension could not differentiate video modes with float
point refresh

like your new driver is trying to apply the fake integer value directly..
Could post your /var/log/Xorg.0.log

Both versions provide non integer refresh rates, the only difference I see
is the new one defaults to 50 Hz, a strange choice. I will have to wait for
the weekend to do more data gathering.

The MythtvWiki User Manual:JudderFree has some info but it still shows
integer numbers from xrandr. I don't know when that changed.

>Are you installing with the new GLNVD or the legacy non-GLNVD libraries?
As I recall, the new GLNVD libraries do not support some of the nvidia

with the new GLNVD.

I am pretty sure the default is the legacy libraries. I will look on the
weekend.

on how to

only the nvidia devs are going to be able to address any breakage).

I am a member of that forum and will gather the needed info and post, but I
hoped to get some ideas here for troubleshooting. Also, hoping there were
others with a similar setup.
When you have a problem like this it is hard to know where the issue lies.

The process for gathering the info for the Nvidia forum is a little more
difficult now that systemd is used. I had a lot of issues when I upgraded
to F22 with gdm, Wayland, kde crashes, etc. If I had more sense I would
leave things alone!

Thanks for the replies.
