Hmmm..., I just followed the installation handbook. Plain, unmodified kernel configuration, which has framebuffer support enabled. |
| 25 |
At the chapter of configuring grub, it mentiones that using the framebuffer was optional. |

If you have configured your kernel with framebuffer support (or you used genkernel's default kernel configuration), you can activate it by adding a vga and/or a video statement to your bootloader configuration file. |

I tried some kernel parameters in grub.conf: |
| 31 |
|
| 32 |
video=vesafb-tng:mtrr,ywrap,1024x768-32@85 |
| 33 |
Still stalls. |
| 34 |
|
| 35 |
video=vesafb-tng:mtrr,ywrap,1024x768-32@60 |
| 36 |
Because I read in a mailing list about vesafb not being able to switch refresh rates (might have been an old mailing list) |
| 37 |
Still stalls. |
| 38 |
|
| 39 |
video=vesafb-tng:1024x768-32@60 |
| 40 |
Removed the mtrr and ywarp in case they were not supported. |
| 41 |
Still stalls. |
| 42 |
|
| 43 |
video=vesafb:1024x768-32@60 |
| 44 |
In case 'vesafb-tng' is not supported but 'vesafb' is. |
| 45 |
Still stalls, but messes up the remaining text on the screen. |
| 46 |
|
| 47 |
In the mean time, I have done the same install in VMware. |
| 48 |
That install boots (succesfully!) with the "video=vesafb-tng:mtrr,ywrap,1024x768-32@85" setting!! (Although in 640x480, but that's caused by VMware). |
| 49 |
|
| 50 |
So my conclusion is that there is something with my hardware configuration. |
| 51 |
I'm using a VIA Epia ME6000 Mini ITX board. |
| 52 |
|
| 53 |
I had Gentoo 2005.0 running on this board, so maybe something changed in this area between 2005.0 and 2005.1? |
| 54 |
|
| 55 |
When I boot this board with the Gentoo 2005.1 LiveCD, it seems to use the framebuffer. |
| 56 |
The isolinux.cfg mentions "vga=791", but that doesn't seem to solve my problem as well. |

-nofb , as suggested by Michael Kintzios, did not help. |
