nvtv - how exactly?

True · Posted: Sat Dec 07, 2002 9:58 am Post subject: nvtv - how exactly?

Hi,

I'm not sure that I understand how nvtv is supposed to work. I've emerged it, added it to the default run level and started it up '/etc/init.d/nvtv start', but what do I do next? Am I supposed to just 'startx'? I've modified XF86Config to include my TV and if I start X then X starts up on the TV but it looks a bit fuzzy. From within X it's possible to bring up the nvtv config box but all the options look more or less bad.. well a bit fuzzy I mean. The picture also has ugly curves along the sides. Am I expecting too much? It's a nice 100Mhz widescreen TV and having seen a PC plugged into a plasma screen (it looked great!) I hoped that it would look like that too...

Is there a step that I'm missing?

Of course you mean 100 hertz tv

But i will be trying to get it to work now

, i will let you know if i got it right(and will post the Xf86config settings here)
I got it working fine one time(before a big hd crash)

Well I don't know for sure, but I think the tv-chip on nv cards isn't capable of exceeding 60Mhz, besides it depends on the chip how good the image quality is, but for using the desktop etc it sucks (some what fuzy and flickring), watching movies however rulez, So don't expect extreem good results,

Cya lX.

The screen is great with macrovision and ntsc(plus color fix), so that should fix the problem(at least the curve problem) i use the 0.4.2 btw this has alot of new options

But it looks like my screens(tv,monitor) are working on 640x800 but X is still using 1280x1024, i know that i can change this with metamodes and all
Which metamodes will i need to let my monitor work at 1280x1024 and my tv at 640x480?

Edit xine's output says this:
tvmode: switching back to regular display
tvmode: cannot find any valid TV mode - TV output disabled
tvmode: switching back to regular display
tvmode: disconnected

Rick, here's the relevant part of my XF86config file, maybe some of it'll be useful..

Thx now my tv-out is working again

I just need to copy my XF86Configs if i want to watch a dvd, but that's much better then going back to that crappy *W* word OS

i just finished installing 1.4 (fresh install) on my tv pc... when i was trying to do emerge nvtv i got the following error : Xxf86vm video mode extensions library required .. strange is, i do have that lib (it's located in /usr/X11R6/lib wich seems the right place for it to be in) ...
How do i fix this one (bar dld'ing nvtv sources myself, but i'd like to keep the system portage only)?

btw, Xfree4.2.1

RickDB: You can use

With X i am kinda a n00b when it comes to tv-out(i got it to work one time but i don't remember how)
So can you maybe say what i need to add to the config to make a seconde server.
My XF86Config:

# Graphics device section
# **********************************************************************

# Any number of graphics device sections may be present

# Standard VGA Device:

Section "Device"
Identifier "Standard VGA"
VendorName "Unknown"
BoardName "Unknown"

# The chipset line is optional in most cases. It can be used to override
# the driver's chipset detection, and should not normally be specified.

# Chipset "generic"

# The Driver line must be present. When using run-time loadable driver
# modules, this line instructs the server to load the specified driver
# module. Even when not using loadable driver modules, this line
# indicates which driver should interpret the information in this section.

Driver "vga"
# The BusID line is used to specify which of possibly multiple devices
# this section is intended for. When this line isn't present, a device
# section can only match up with the primary video device. For PCI
# devices a line like the following could be used. This line should not
# normally be included unless there is more than one video device
# intalled.

# BusID "PCI:0:10:0"

# VideoRam 256

# Clocks 25.2 28.3

EndSection

# Device configured by xf86config:

Section "Device"
Identifier "322"
Driver "nvidia"
# unsupported card
#VideoRam 128000
# Insert Clocks lines here if appropriate
EndSection

# **********************************************************************
# Screen sections
# **********************************************************************

# Any number of screen sections may be present. Each describes
# the configuration of a single screen. A single specific screen section
# may be specified from the X server command line with the "-screen"
# option.
Section "Screen"
Identifier "Screen 1"
Device "322"
Monitor "My Monitor"
DefaultDepth 24

Subsection "Display"
Depth 8
Modes "640x480" "800x600" "1024x768" "1280x1024"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "640x480" "800x600" "1024x768" "1280x1024"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
EndSection

And my tv-out config looks like this:

Section "Screen"
Identifier "Screen 1"
Device "322"
Monitor "My Monitor"
DefaultDepth 24
Option "TwinView" "On"
Option "TVStandard" "PAL-G"
Option "SecondMonitorHorizSync" "30-50"
Option "SecondMonitorVertRefresh" "60"
Option "MetaModes" "800x600,800x600;640x480,640x480"
Option "TwinViewOrientation" "Clone"
Option "ConnectedMonitor" "TV"

Subsection "Display"
Depth 8
Modes "640x480" "800x600" "1024x768" "1280x1024"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "640x480" "800x600" "1024x768" "1280x1024"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "1280x1024" "640x480" "800x600" "1024x768"
ViewPort 0 0
EndSubsection
EndSection

Thx in advance,

Copy and paste your screen section from the TV out XF86Config file into your primary XF86Config. Make sure the two screen sections have different names (Singlescreen vs. TVscreen, for instance). Then duplicate your current ServerLayout part in your XF86Config. Give the two serverlayouts different names (Identifier), for instance Standalone and TV. Let one of them contain the line 'Screen "Singlescreen"' whereas the other contains the line 'Screen "TVscreen"'.
Now you can run the TV-configured X server by typing startx -- -layout TV at the console. I think (better check this) the default is that the first serverlayout will be used if none are specified, so letting your regular serverlayout be the first one will prevent you from having to type more than 'startx' in those cases. You can easily make a script to simplify the selection process further.

Thx for the help, but it gives an error when trying to startx(X won't start on boot with the new config):

Ah, yes. My explanation was perhaps a bit dubious. You need to make two quick adjustments:
The following code

Alright its working great now, thx again for the help

Damn....so cool tip

I love the idea of running two X, one for TV and one for normal staff

So I can keep working normally while my wife watches Friends (i know, i know...)

But it doesn't work....After typing

hm...
You know you don't need to customize your XF86Config, it's sufficient to type

Hi, I am using a Xinerama and TwinView setup to use my TV and a second monitor.
I seem to have everything setup fine. The TV is to the left of the monitor and windows can be dragged across... cloning doesn't seem to work, but that doesn't bother me too much.
The only problem i have is that the display appears in black and white.
The TV only works when i use it in a depth of 24, and a resolution of 1024x768.
I have it running from the S-Video out of my Nvidia Ti 4200 to the scart socket of my TV.
Movies with mplayer look great, but i would love colour.
Also, the TV can do both NTSC and PAL, its a european tv, but bought for that feature so an american PS2 would work with it.
Thanks
alex

Turns out that using NTSC-M and COMPOSITE fixed it.
I read that scart can actually delver all three if its a good scart socket and so tried different values. Guess the TV picked up one and sorted it out.

the big problem I have with running multiple screens, both TwinView and and two monitors and two screens is that I get Tearing on the TV. It's just like playing a game when having lots of fps and low hz.... If I only run one X with just the TV I don't get this annying shit. should be some vsync stuff or something to fix this.
