|
|
I'm running Gentoo with kernel version 2.4.18. I have framebuffer devices enabled in the kernel (and I'm pretty sure it's done correctly, I paid attention to the HOWTO on linuxdoc.org), but they're not working quite right. When I select a screen mode, the video flickers and the text is re-drawn correctly, but a few seconds later, it reverts back to the default screen mode.
Have any other Gentoo users seen this before, or am I in the wrong forum? |

Have you tried different resolutions for your fb? _________________ This message self destructed a long time ago. |

I'm not sure I understand your suggestion. My lilo configuration uses 'vga=ask', so I choose my own scan mode at each boot, if that's what you're talking about. I've tried more than 1 of the scan modes,and each one had the same result. If that's not what you're talking about, then I'm lost. |

I'd suggest that you specify a VGA mode through the vga= command, rather than the "ask" option. Take a look at /usr/src/linux/Documentation/fb/vesafb.txt for a list of resolutions that you can specify to vga=. _________________ Chad |

I've tried passing values in the lilo configuration, but even when i have a vga=### instead of 'ask', it still shows me the menu for entering my own scan mode. |

Silly question, but did you restart lilo (by typing lilo at the command promtp). I don't mean to insult your intelligence, it's just that that is what I think would solve the problem. _________________ Postcount ++ |

One thing you might want to check is which driver you're using.
I had somewhat similar problems with my laptop (Dell Latitude CP), which worked fine with several other distributions, so I was pretty sure it was not a hardware problem.
I eventually tracked it down to the fact that I was using the "neofb" driver (seeing as how I had a NeoMagic 128 video "card").
I took that out of the config for the kernel, but left vesa FB support on. This caused it to use the vesafb driver, which has worked fine. |
