Open source drivers are getting pretty good these days. I haven't had any problem with Intel or AMD hardare.
Intel
I hear the old ones are pretty bad, but my G4500HD does everything I need well. Video acceleration could be better though. There isn't a proprietary driver for Intel either, your only choice is open source. The composited 3D desktop in KDE ...

The X Window System uses a client-server architecture. The X server runs on the machine that has the display (monitors + input devices), while X clients can run on any other machine, and connect to the X server using the X protocol (not directly, but rather by using a library, like Xlib, or the more modern non-blocking event-driven XCB). The X protocol is ...

I'm not positive I know what you mean, but are you looking for something like this?
I used Graphviz, which takes text input files describing transitions, and figures out the graph automatically. Here's the exact command:
$ sed 's/-/_/g' input | gawk '
BEGIN {print "digraph g {"}
END {print "}"}
match($0, /from ([^ ]*) to ([^ ]*) \((.*)\)$/, ...

I can address your question, having previously worked with the Linux FB.
How Linux Does Its FB.
First you need to have FrameBuffer support in your kernel, corresponding to your hardware. Most modern distributions have support via kernel modules. It does not matter if your distro comes preconfigured with a boot logo, I don't use one and have FB support.

Although this post is based on facts, it still contains my personal experience and opinions.
Nvidia
Although there is a project for OpenSource drivers, you probably need to consider Nvidia being closed source drivers only. Now in case of Nvidia this doesn't really bring a lot of bad things since they really work on their drivers very hard. The best support ...

The traditional stack is built upon 3 main components:
X server which handles displaying
Window manager that put windows into frames, handles minimizing windows etc. That's part of separation of mechanism from policy in Unix
Clients that perform useful task as displaying stackexchange website. They may use X protocol directly (suicide), use xlib or xcb ...

Ubuntu is a good choice for a first distribution, if you want something you can get up-and-running quickly and easily. You might also consider fedora as well.
You can certainly theme an Ubuntu installation. See this thread for a good starting point - HowTo: theme your desktop

Your laptop should have /sys/class/backlight. For example, /sys/class/backlight/acpi_video0/brightness. You can write (echo) values to this file to adjust brightness.
cat /sys/class/backlight/acpi_video0/max_brightness > /sys/class/backlight/acpi_video0/brightness
This will set the brightness to max. Just put it in an init script on boot.

First of all, there is really no Linux graphics stack. Linux has no graphical display capabilities.
However, Linux applications can use graphical displays and there are a number of different systems for doing that. The most common ones are all built on top of X windows.
X is a network protocol because in the middle of an X protocol stack you can have a ...

I guess, it is not possible to see PDF file in terminal but you can check it's content by converting PDF file to text.
You can do this as:
pdftotext a.pdf
It will produce a.txt file which you can read into VIM.
For ubuntu-variant, this binary is available in following package.
poppler-utils

Unfortunately, it's still very buggy, as per this post on the openSUSE forums lots of stuff still doesn't works:
What I have working so far:
Retina Display - openSUSE looks fantastic at 2880x1800!
Booting in emulated BIOS mode
Booting in EFI mode
Keyboard and Trackpad - full support including the function key on the keyboard, the keyboard ...

Ubuntu offers all of that:
It was designed from the on-set to be a newbie-friendly Debian; I've used both, and it certainly is easier, at least on the surface (i.e. the basic stuff).
It has some of the largest collection of software of all distros; this includes a whole bunch of development stuff (all major programming languages, a whole bunch web ...

You can use vga_switcheroo to switch between graphic drivers / GPU's, but it doesn't work on the fly. Watch this question for any on-the-fly solutions that come up.
One guy has written up a very detailed tutorial on setting this up under Fedora 14/Ubunut 10.10. You might have to adapt for 11.0, but it seems to cover the bases pretty well.
Ubuntu has ...

Analyzing the code you posted as well ass acpi_call leads me to the the conclusion that most probable candidates should be:
echo '\_SB.PCI0.PEG0.PEGP._OFF' > /proc/acpi/call
to turn the card off and
echo '\_SB.PCI0.PEG0.PEGP._ON' > /proc/acpi/call
to turn it back on again.
You should be safe to test those, as the README for acpi_call states:

You may also try to use ffmpeg to create a movie out of a sequence of images and then convert the movie to a GIF animation (again using ffmpeg).
# cf. http://pages.uoregon.edu/noeckel/MakeMovie.html
# first convert an image sequence to a movie
ffmpeg -sameq -i %03d.jpg output.mp4
# ... and then convert the movie to a GIF animation
ffmpeg -i output.mp4 ...

Comic viewers (such as Comical, Comix, QComicBook, or cbrpager) usually have a double-page mode.
In addition, Geeqie has two-image modes and a quadruple-image mode. However, the sub-windows seem to be independent of each other (when you change one, the others don't change).

According to the official Intel Linux Graphics Drivers website Linux should support Intel® HD Graphics P3000 included in the Intel C200 Series Chipset Family out of the box.
The cause of your problem is according to the information provided by Intel that Intel® HD Graphics P3000 is only available with select Intel Xeon processor E3-1200 SKUs. So please ...

The most direct answer is to use jp2a : JPEG to ASCII.
Maybe you can use the famous ascii-art library : libcaca. It even allows to see movie in a terminal, so it should also works for simple jpeg.

As far as I can tell from your problem description the correct term for what you want is "hybrid graphics" as you only use either adapter to power your monitor (actually any output), not both at the same time.
An overview over tools for what you want can be found (for example) here. You may be looking for the tool bbswitch from the Bumblebee-Project. Yet, ...

Have you tried the netpbm tools? This will work with R8G8B8 and other 8-bit RGB orders.
For a width 100 height 200 RGB order raw file:
rawtoppm -rgb 100 200 input.rgb > image.ppm
ppmtorgb3 image.ppm
You will now have 3 pgm format grey-map files, each suffixed .red .grn and .blu. These .pgm files are almost a raw binary format, except for the short ...

There is no fundamental reason for not being able to get the same quality output from graphics cards for the same hardware under Windows and Linux. However the development of software, both the drivers, and any application software, needs to be written and doing that both for Windows and for Linux just takes extra effort.
Such double effort always takes ...

Just because system settings doesn't correctly report your graphics card, doesn't mean it's operating incorrectly. I'm not sure what you mean by 'Getting OpenGL to work', but I'm guessing you mean Verifying accelerated OpenGL?
The two major components of basic acceleration are Xv, and GLX Direct Rendering. Xv does Hardware Video Overlay, and GLX Direct ...

Depending on which system you are on the location of the X log may be different but on Linux: /var/log/Xorg.0.log. If you search for the word driver you will be able to see lines like this:
[ 34.252] (==) Matched fglrx as autoconfigured driver 0
[ 34.252] (==) Matched ati as autoconfigured driver 1
[ 34.252] (==) Matched vesa as autoconfigured ...

To answer your original question, yes you are using the OpenChrome driver. It just unfortunately has minimal support for your chipset, even less if it isn't the most recent.
As of now you should be able to get Basic 2D, and whatever 2D acceleration was supported for your chipset. Its up to you to say if its 'good enough', or worth changing to something ...

If you simply have a series of .jpeg images that you wish to display in a tty, you can use aview or asciiview. When calling asciiview with an image, it will convert the image to the .pnm format - using an external program like NetPBM or ImageMagic - before passing it to aview for displaying. The .pnm is the ascii image format used to represent the image as ...

I Installed Arch in virtualbox
A virtual machine running in vbox uses a emulated video card instead of your nvidia card.
Which means nvidia like driver is unnecessary.
Try X -configure first, which will generate a probed xorg config, but modern Xorg shouldn't need that at all.
(If you have /etc/Xorg/xorg.conf, remove it)

I don't think you will have any trouble with unsupported modes. The monitor reports whatever crazy layout it wants and your card should be able to send that resolution up to the supported maximum dimensions.
What you will run into is that netbooks typically don't have the horsepower you'd want to do high resolution video editing.

Current version of RandR protocol does not allow to use multiple graphic devices. It is expected to be implemented in RandR 2.0, but there is no estimate time of release (so do not expect it in the next two years). You might want to see (for example) here:

However, it might be possible to configure your monitors without ...
