My laptop has a built-in Intel graphic board. I read that kms for Intel is
supposed to be included in kernel-2.6.29, but whenever I put rhgb on the
kernel boot line i grub (and remove vga= and remove nomodeset), then the
computer boots and I can tell that it's logging into kde, but the screen is
just black and I am unable to change to another vt. When I use vga= and
nomodeset, then Plymouth works and so does X.
Am I missing an option on the kernel boot line in grub? Do I have to
configure something? How do I enable the native modeline required to get
my laptop to use its native resolution? I tried xrandr, but it was unable to
use the native resolution. Yet, I have read that the kernel is now supposed
to do this...
Any ideas?
I've been through this a few times over the last couple of years. As
best I can figure it, VGA= on the kernel line is interpreted by vesafb,
and works if vesafb supports your card.
On my current desktop, an HP DC7700, vesafb drives my screen at
1280x1024 so I don't need to go further.
Earlier releases didn't support the Intel graphics in various of my
computers, so that tends not to work.
If it does work, then it gets undone when some smartiepants decides to
load a font I don't need or want, and the screen gets set to 30 lines.
So I need to turn that off.
If I get to the login screen (runlevel=3) in a text console mode, then
usually the best driver to use is intelfb. For some fairly decent
information on it,
modinfo intelfb
I like 1280x1024. so in /etc/modprobe.conf I have this:
options intelfb mode=1280x1024@70
Sometimes, something upsets the console and it goes all distorted so I
have to do this too:
fbset -a 1280x1024-70
Valid arguments are listed in /etc/fbset
Note, I think that that graphical boot console is all very nice, but not
on my computers. I turn it off, and remove quiet too: if something goes
wrong, I want to know about it first time.
