I know that nvidia does overscanning for a reason, and I appreciate what it is trying to accomplish. In the mythtv setup screens it is very easy to compensate for this for watching live tv by setting uderscan, so that is great. But, for the general MythTV GUI, I cannot see the ouside 3/4" of it because of NVIDIA's overscanning. I have not had much luck with nvtv either. is there a way to setup underscanning for the MythTV GUI similar to how it is done for the live tv settings in Myth setup?
Thanks
In case it matters, my video card is GeForce 4200 Ti

just to make sure. Did you turn off overscanning in your XF86Config-4 file.


I think the default TV-Out sample may use something like 0.7. Try turning this down, or commenting the whole line out.

Yeah I tried turning it off, which is no good because then the actual viewable picture is smaller that the physical tv screen so I get these bars around MythTV.


My default was at 0.8. I 1st tried 0.5, I couldn't really tell a difference, then I tried it at 0.3, still appeared that there was no change from the original 0.8 setting, then again at 0.1 and still cannot tell.

Turn overscan off in your /etc/X11/XF86Config-4 and restart X. Use nvidia-settings to adjust it interactively (along with doing any other video output tuning desired) then save your settings.

Search for posts by me that mention both nvidia-settings and /home/mythtv/.fluxbox/apps for details on how to get those settings applied at startup.

Alternatively to answer your orignal question you can adjust the gui size in the setup->apearances menu.

I did adjust the gui size in the setup > appearances menu, but I noticed since I've done that, leaving live tv can be very slow...like the screen stays black after hitting back/exit. I'm wondering if that is a result of the gui size being changed.

I was not aware of such a thing...I'll give that a shot.

i always thought it was slow from deleting the live tv cache file. but i've always been running with the gui size tweaked so now i'm not sure. hmmm...

I would say you are probably right, I changed the gui settings back to 0 and still its about the same time leaving live tv

That delay is the time it takes to delete the live TV recording cache. This is why you want the cache directory to have a filesystem with good delete behaviour among other things.

How would this be done? I've checked man XF86Config-4 for over, Over, scan, and Scan, I find nothing to indicate that is an option. I find people doing it for Xorg, but that's not what KnoppMyth uses right?

I can't get my system keep nvidia-settings value.
I read what is written in KnoppmythWiki, but it doesn't work for me.
the only thing I changed is the OverScan. It does work when I change it but it is not applied on reboot.

I did this:



so What is the problem?

I'm using R5A30.1 with a FX 5200

Uhm... You didn't provide enough details for us to make an intelligent answer.

- What kind of video card are you using?
- If it's an Nvidia, have you got the nvidia drivers installed?
- Have you got a suitable XF86Config-4 file for your card/drivers
- Are you trying to do TV Out?
- If so, have you got an suitable XF86Config-4 for TV out?

Without even basic information we're just playing "Doctor it hurts!" and all I can suggest is make two searches of the wiki and post again in the morning.

EDIT - For the sake of clarity, I was talking to RichardBronosky here...

This works for me.

You would need to edit your /home/mythtv/.fluxbox/apps and add the nvidia-settings line at the appropriate place. Be very careful about the spaces and punctuation, don't confuse the square brackets [] with the curly brackets {}.

tjc: thank you. I'm gonna try this
