We should all be running WinWoes 'cos it is 'good in the video area?'
Apple can make it work because they sell the whole box and
can control the hardware. But the open-source OSes don't
have the resources to support video.
Not so. You have cause and effect reversed.
The F/OSS folks who *must have* a good video and GUI to get some *other* set of
tasks accomplished simply buy the commodity that suits them.
Lots of *n*x developers use a Winbox or Mac with nary a care for the politics or
religion, just as they would a twist drill. Not throw-away, but expendable
The haven't time to play with these 'appliances', and begrudge even time wasted
on updates and fiddling (hence my move form OS/2 to OSX).
Very much a minority market vs gadzillions of office-workers and home users.
Those who would *like to have* a good video and GUI for reasons *other than*
getting some other job done, are more likely to use Linux, and DO spend a good
deal of time modifying and updating their personal WS.
This attraction has created a huge pool of Linux-aware folks, the best of whom
are very savvy coders, and the worst of whom can at least be trained to be
better admins than Win-gulls, if only 'coz they actually give a damn.
That labor pool of trained-at-the-expense-of-others is what drives IBM, HP, Sun,
etc. to embrace Linux, not technical superiority. All of these companies are
*service* providers - hardware and software is incidental.

At NT4, MS moved video drivers into Ring 0 to optimize bloated code for the
single-user GUI. NT 3.51 was far more stable, and MS struggled for years to fix

Even if a single-user GUI-prioritized environment is what you *want*, other
parts of the WinWay come at too high a price to go down that road.
Memory management, the fs, and other-than-video I/O need that sort of critical
priority more than pretty pictures alone. Things that get costly in time and
money if they do not have it.
Old or new branches of X are rooted in a very different architectural philosophy
than Win vid, and would have to start over from a clean slate to even match the

Note that many folks have been promising a Linux that used Win Vid drivers
directly for years, but it has yet to take make a ripple.
You know that vendors will make drivers for windows, so
making it easy for them to port to your OS is good for
That would require a major rework of the X environment, if not the OS itself.
Its time for open sourcers to realize they can't do
everything themselves. I don't care if a driver is binary
if it works. I want to have options.
Options to what end?
Apple, for example, have a very limited selection of video hardware, yet I can
no longer see enough difference to care.
Only a 'game' machine or high-end studio-grade editing can justify the upgrade.
Not much else even stresses the low-end video.
Very small market, once purpose-built game boxes and 'good enough' commodity
Winboxen are factored out at one end, and big-bucks studio gear at the other.
A binary driver on a system doing public services?
Not on my box! That's about the most important reasons why my windows
servers are always in a DMZ and my OSS boxes are mostly not.
anything else I'll say yes that would be convenient. However I lost the
faith in manufactures creating good drivers, whether they are windows or
anything else, but I guess that most manufacturers don't want to provide
too much specs or source because then it's quite easy to see what a mess
they sometimes make of their hardware.
There are servers, and there are desktop/laptop 'productivity appliances'.
The entire 'available' market is too small for any of the *BSD's to focus on
their weakest attribute - the GUI.
If DragonFly were to ignore - *totally ignore* video, USB, sound, etc. for (at
least) a full 12 months, and concentrate solely on kernel, IP, fs, a few key NIC
and storage-controller drivers, and the integration and security of all these,
. .. it would have a far better chance of carving out a respectable chunk of high
A 'differentiator' so to speak, where it could best demonstrate superior value.
A DragonFly Xen or VM 'host 0', for example, that could host other OS more
efficiently and/or with superior portability across a high-speed 'fabric'.
All the rest would follow *eventually* - just as they did for Linus' kernel.
But that needs a well-respected and stable core before the big wave of interest
and committment can afford to jump aboard.
So long as the project tries to incrementally drag all the *noisy baggage* along
at the same rate as the vanguard, the never-ending rework of code and libs
against a moving core target, coupled with the rapid external progression of
hardware development, will prevent it catching up any time soon enough to matter.
The shortest distance between two points is not a straight line.
It is folding the paper so the points *touch*.
