[gentoo-user] First time kernel compiler experiencing some problems

[Vlad Dogaru]

Hello,

after a couple of failed attempts some time ago, I actually ended up
with a kernel that boots. However, I am experiencing some problems which
I think are at least in part due to my perhaps incomplete kernel
configuration.

First of all, my console is still in 80x24 mode, although I pass
video=vesafb:1024x768-32@72 to the kernel. I have compiled vesafb-tng
into the kernel, so specifying the vga mode is not needed, right? If I
add vga=0x318, the kernel complains about an unsupported mode and makes
me choose another. However, I know from my previous (genkernel-created)
kernel that these paramters work for my hardware setup.

Secondly, I installed nvidia-drivers, but the X server refuses to load
glx. I can't check for the exact error now, but it's something about an
unrecognised/unsupported format. If I set opengl to xorg-x11, X starts
(but I suppose it's not by far the same thing).

Could this be linked to the fact that my detected X settings are a bit
strange? For instance, the monitor VendorName and ModelName are just
generic strings and the subsections for the Screen section only contain
"ViewPort 0 0" in addition to Depth, which varies (correctly as far as I
can tell) from 1 to 24.

Other than that, and a bit offtopic, too, today has been both very fun
and incredibly educational (but a bit sore on the eyes). But after about
13 hours, I might not make much sense. Apologies beforehand if that is
the case.

Vlad

PS: I tried to send this a while back, but without success. If it did, however,
get sent, then I apologise for the double post.

In my experience "video=vesafb:1024x768-32@72" never sets the console
font size, just the screen resolution. "vga=0x318" hasn't worked for me
for 5 years or so and i recommend instead that you use a smaller vga=
statement for the initial font and then setting (look at the list, i
don't remember them) up /etc/conf.d/consolefont to use the sun-12x22
font, which is the biggest and looks the best on 1024x768 imho, or
another font you like.

did you use "eselect opengl set nvidia"?  There's a nice nVidia+HW
accel. guide on the gentoo sites that I highly recommend.  MAke sure
DRI is disabled, although that usually happens automatically.

First of all you probably should enable I2C support in the kernel so
you can better communicate with some hardware in your computer over
simple I2C protocol.  The monitor name/vendor name are just identifiers
and mean nothing, and the screen section usually looks something like
that, but you might want to look up online and add horizontal and
vertical refresh rates for good resolutions.

i love gentoo.

It did get double sent.

you even appear to understand the use of commas ; )

I manged to solve the problem by not compiling nvidia framebuffer
support. Now even the nvidia-drivers work.

It does give a uniques feeling of satisfaction, especially after
finally compiling DMA into the kernel :)
