| Post subject: | Blank Screen After Installation Redux |
Hey, all, I was here back in December trying to get Knoppmyth to work on my machine (ti4600, PVR-150, Audigy) and got caught up in other stuff for the past few months so couldn't make it work. I thought I'd try the new release to see if that would produce results, but once again the same thing is happening: Installation appears to go fine, but at the end of the process the machine (which is hooked up to both a generic flat screen, and to a TV through the S-Video out) goes black. I think what it's trying to do is go to the TV, but that's not working, so I've got nothing to work with. I've tried Ctrl+Alt+F1, but that doesn't have any apparent effect. The problem this leaves me with is that I can't figure out how to tweak anything--because I can't see anything to tweak it! When I boot, the TV gets a brief test signal, then the monitor shows the boot process. It tries to start gnome and that's when it all goes black. So, that's my dilemma. I'd like to use Knoppmyth but I'm stumped as to how to proceed. Presumably I need to stop the process before it tries to start gnome...but how? ANd then what? |

http://www.knoppmythwiki.org/index.php?page=TroubleShooting Are you trying to hook two monitors (TV & monitor) to the box? Or just using an odd display device? |

I was just using the monitor for installation. Can I use the the TV for it? I would think stuff would already need to be installed before the computer could talk to the TV, as it were. Thanks. |

I do it all the time. The only "monitor" connected to my box is the TV and I've done many upgrades and installs like that. Any video card with TV out should just work in the old low-res text modes that the installer and consoles use... |

Well, huh. OK, let me try that. This is probably a really stupid question but: do you switch from your video out to your capture-card out after installing. Or--hell, maybe I've got my freakin' cables backward. Output from the cable box goes into the PVR...output from the computer goes from the Ti4600. Right?  Doy.

OK, I'm not that stupid, fortunately. I do have the output going from the graphics card to the TV. |

OK, this sort of works. Looks good in-between all the flickering snow/color bar patterns. In other words, I see the Ubuntu screen and then lots of flickering--not a stable image. Then after that I get a vertically rolling graybar pattern. So. What have I learned?

Can you do Ctl-Alt-F1 and get a stable text console? |

No. Ctrl+Alt+F1 doesn't work under any circumstances. Not if I've only got the TV hooked up, not if both TV & monitor are hooked up, not even if I'm just booting from the CD. (? That last suggests maybe I shouldn't be using a USB keyboard but if it's a problem, it's not showing up in any other way; the setup routine seems to perfectly configure the keyboard). Interestingly enough, now the TV is always getting a signal (the rolling one) instead of just being black. Did KnoppMyth reconfigure itself for when I disconnected the monitor? |

No idea. Look at the blank screen after install page again. It now includes basic instructions on using the install CD as a rescue disk so you fiddle with the X config. |

OK, I was trying to telnet/tty in, and it appears to me that the machine is totally locked up. I'm going to try the CD-rescue thing. Thanks. |

No telnet server (been at least 5 years since I even used a telnet client for anything other than to check that a tcp port was responding), ssh is the correct remote access protocol these days. |
