 |
|
Hey I got gentoo running but I am getting an error in grub. It says I am passing an invalid argument for my video setting. I hit return and select one manually. The highest that runs is "6" or 80x60 caracters. Now how do I set this up correctly? I have tried many lines and have seen vga=788, vga=0x31a, video=aty128fb:1024x768-16@60, and video=vesafb:ywrap, mtrr. Ok so which is the correct way to set this up? The Grub manual doesn't say much.
Thanks,
A.J. |

The video options your passing are actually being passed to the kernel. So it depends on what framebuffer support you have compiled into your kernel. So for instance here are the video options I pass to the kernel, as you can see I have vesa support built into the kernel:
| Code: | | video=vesafb:ywrap,mtrr vga=0x31B |
Here is a quote from Narada's bootsplash faq showing various vga modes:

----+-------------------------------------

32k | 0x310 0x313 0x316 0x319
64k | 0x311 0x314 0x317 0x31A
16M | 0x312 0x315 0x318 0x31B |

If all you want is nice screen resolution and your using the 2.6 kernel, you can configure vesa-tng support into your kernel and set the default mode in the kernel configuration under Device Drivers --> Graphics Support --> Vesa Driver Type (vesa-tng) --> (1280x1024@60) Vesa Default Mode (NEW). The last part you will have to type in, and the format is "Xres"x"Yres"@"refresh rate". That way you don't even have to worry about passing paramaters to the kernel at boot. Hope this helps and if it does remember to append [SOLVED] to the topic of your first post.

Well I used genkernel to set it up so I'm guessing my voodoo3 card can't support whatever is default. Let me try taking out all of those video settings from Grub and see if it still is upset with something.

If you use genkernel, you can still run genkernel --menuconfig all and edit the kernel configuration manually. As far as you card goes, there is no reason why it shouldn't be able to handle a reasonable framebuffer resolution. I don't belive that genkernel is configured with any framebuffer support, at least the last time I looked, so at least go to /usr/src/linux and run make menuconfig to see what options your kernel was compiled with.
