| Post subject: | grayscale: only X session on TV screen (solved) |
I did a clean install of KnoppMyth R5C7. It basically worked fine with a TV connected. Then I did some administration (nvram-wakeup) and therefore I connected a CRT monitor instead of the TV. Now I switched back to the TV and now the X session has no colour anymore but shows only grayscale (desktop and other programs like Mythtv). But during booting with TV connected it starts in colour and stays in colour until X starts and when I shut down the splash screen ("welcome to knoppmyth") colour cames back again. This only happens on the TV screen. When I connet a CRT monitor parallel with the TV the CRT monitor shows X (and everything else) in colour but the TV has only grayscale in X. Has anybody an idea, what has gone wrong here?? |

how is your TV connected to the PC? are you using an S-video cable? Are you then converting the S-Video to composite? What is the TVOutFormat in your XF86Config-4? If you have a S-Vidoe to composite converter, try setting TVOutputFormat to COMPOSITE Code: Option "ConnectedMonitor" "TV"
Option "TVOutFormat" "COMPOSITE" |

Thanks, that helped: I put those lines in /etc/X11/XF86Config-4 Code: [....]
Section "Device" [...] Option "TVType" "PAL" # Option "TVVScan" "over" Option "TVOutput" "Composite" Option "ActiveDevice" "CRT,TV" [...] and then nice bright colour was back agein
