| Post subject: | WinTV PVR250 + Nvidia GeForce 4Ti 4600 - video out problems |
Hello I built this system for 3D. The video card has an s-video port going out, and I booted it up once with only that attached to my TV and I was able to see the desktop. I know that the port works. When I boot KnopMyth using ONLY the s-video connection to my TV, I get the ram check, bios, and all that text startup stuff that PCs do, but when the computer gets to the GUI, I get a scrambled picture. What can I do? I have no idea where to start. Thanks, --------------------Steve |

You need to specify your refresh rates in the /etc/X11/XF86Config-4 file. usually vert 30 - 50 and horz 60. Most TV's can't handle the refresh rates of a default knoppmyth install. If you are using R4v2 then there should be some example XF86Config files for TVout on nvidia cards. |

If you did the KnoppMyth install in the /etc/X11 folder you should see a file called XF86Config-4.nvidia-tvout.sample. I would suggest Making a copy of your current config just in case, cp XF86Config-4 XF86Config-4.backup then do cp XF86Config-4.nvidia-tvout.sample XF86Config-4 Restart Xwindows, and it should work |

KnoppMyth doesn't include Xwindows, rather it includes the X Window System. |

Hello I looked at the XF86Config-4 file, and it states that there are 2 values for the horz where you specify 1. Does it need to be 2 values? you said: usually vert 30 - 50 and horz 60 config file says: HorizSync 28.0 - 96.0 VertRefresh 50.0 - 76.0 Also, are the "modelines" important? thanks again, --------S |

the modelines should be fine as they are, and for tvout the vert only has one value not a range. Did you look at the example config files mentioned in this thread? |

Thanks for that overwhelming vote of support, Turkish. I DID look at the example files. When I boot with the settings you specified, I got a message when the system is starting up (before Xwindows): ------- Press <RETURN> to see video modes available, <SPACE> to continue or 30 secs ------- When I hit return, I get an array: ------ Video Adapter: VESA VGA Mode COLSxROWS: 0 0F00 88x25 1 0F01 88x50 2 0F02 88x43 3 0F03 88x28 4 0F04 88x30 5 0F05 88x34 6 0F06 88x60 Enter mode number or "scan": ------- If I type "scan" then the screen flashes around for a while and comes back to the selection menu with a 7th option: 7 0100 40x25 ------- When I select any of the options, before or after using the "scan" option, the system loads and stops at an ASCII window: --------- "I cannot start the X server (your graphics interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem? <Yes> <No> --------- If I select Yes, then it asks me for the root password to run a configuration program. Then the screen goes black. If I select No, then I am dumped to the command prompt. I'm not really sure what the problem is. |

when you get dumped to the command prompt login as root, and cat /var/log/XFree86.0.log close to the end of the output should be some sort of error message telling you why X didn't start. |
