Problem with Xorg and maybe wscons too?

That's harmless - ofb doesn't support virtual consoles in
3.0.1 ( it  
does in -current though )

Hmm, this is the problem:
Fatal server error:
xf86MapVidMem: could not mmap screen [s=80000,a=90000000]
(Invalid  
argument)
And here's why:
(--) PCI(0:16:0) ATI
Technologies Inc Radeon RV200 QW [Radeon 7500]  
rev 0, Mem  0x98000000/27, 0x90000000/16, I/O 
0x0400/8, BIOS   
0x90020000/17
The register range at 0x90000000 is only 64kB ( hence /16 as
in 16 bits  
wide ) but the radeon driver tries to mmap 512kB which of
course fails.
This is a bug in X.org's radeon driver, I reported it to
x.org a while  
ago and it should have been fixed in 7.x
Meanwhile - why don't you just use the XFree86 4.5 that
comes with  
NetBSD? It doesn't have this problem as far as I remember
and the  
graphics chip is old enough to be fully supported by
XFree86.

Hello again

Now I've installed Xfree86 from the cd's sets, and tried to
get it
working... but I end up with a black screen at the best of
times. I
had to enter modelines in the Monitor section in order to
get Xfree86
to start at all. I calculated them with:
htt
p://xtiming.sourceforge.net/cgi-bin/xtiming.pl
Based on the data I found on Apple.com

X is acculy running, there's twm, xclock and some xterms in
the there
somewhere... but I can't see it. I also tried to kill X and
ended up
with a psychedelic pattern over the entire screen. (over ssh
this is).
It's square dots in wave like patterns, a bit like an 80's
fabric
print maybe. And I get the console in it... all messed up,
but it's
there.

So, thanks for all the help so far!
And here's something new to bite in.

Take care!

some iMacs have similar problems - the monitor works at a
fixed 
horizontal frequency and is very picky about that.
change
HorizSync  	71.0-73.0
to
HorizSync	72
and get rid of the modelines. Maybe that will help,
something similar 
works on G3 iMacs. You may also want to try different
resolutions, for 
instance I got 1024x768 to work but not 800x600.
If that doesn't help try to generate a modeline that matches
72kHz 
horizontal as accurately as possible.
Finally - have a look at your XFree86.0.log - maybe the
monitor reports 
its parameters and supported modes.

Hi,

In case it helps, this (below) is the XF86Config I use in
the eMac. I
use it in 1024x76824 mode and works fine -- I haven`t tested
the
800x600 mode.
I`ve got the ModeLines from some other config file for a
eMac, I think
they were calculated with some automated configuration
program or
calculator.

I get also this pattern when exiting X11, but the text
displays in
white background so a simple "clear" will clean up
the pattern and you
will get normal console black (although some minimal
distortion
remains at the edges of the screen where no text is
displayed).

Please note that when using wskbd0 in both the wscons
wsdisplay0 and
the X server, it will detach from wsdisplay0 when the X
server starts
in NetBSD-3 (not in NetBSD-2). You can reconnect it to
wsdisplay0 and
everything will work fine (a simple re-plugging of the
keyboard USB
cable will do it).

In NetBSD-3, without the iBookHacks the system will crash.
In NetBSD-2, it won`t crash but you will have no console
screen
(although you can type commands and they will work, of
course).
In fact, this will disconnect the eMac monitor, so it can be
of use
for some things.

Hi again

I got 1024x768 to work with your modeline, and I tried three
modelines
I found on the Internet, that where said to work on eMacs
running
XFree86 in 1280x960. None of them did work:/ I did also try
two
different modeline generators, and none of their outputs did
work.

ModeLine        "800x600" 112 800 816 824 840 600
616 624 640 -hsync -vsync
ModeLine        "1024x768" 100 1024 1108 1280 1408
768 768 780 796 +hsync +vsync

#Modeline "1280x960" 122.25 1280 1328 1424 1696
960 961 964 1002
+hsync +vsync -csync
That modeline is from a working XFree86.config... at least
if you are
using Gentoo. And maybe only 1.25GHz modell?

Is there something about the diffrent eMac modelles? The
700MHz one
have an nVidia card, the 1GHz ATI Radeon 7500 and the
1.25GHz has an
ATI Radeon 9200.
So maybe the modelines are different for the different
modells?

According to the eMac manual, the monitor will only work in
72kHz
h.sync and these resolutions:
640x480138Hz
800x600112Hz
1024x76889.0Hz
1152x86480.0Hz
1280x96072.0Hz

Which is strange, because I remember there being 60 and 72Hz
in
1280x960... I could be wrong though.

Maybe it would be a good thing to have a list of working
modelines
collected on NetBSD.org somewhere?

Take care!

How do I make users available to use X?

Hmm... supposedly the modelines depend only on the monitor,
which is
expected to be the same across these eMac models (although
it may not
be... not sure).

This rate is correct for my eMac at 1024x768 too.

Try with this modeline too; it's from the same file from
which I got
my modelines:

ModeLine "1280x960" 100 1280 1288 1392 1664 1024
1027 1030 1064

Hi Adrian,

not that I have any specific knowledge about eMacs.
But somewhere along the line you mess up horizontal
and vertikal sync; and I am not shure to which one
the eMac monitor restriction applies.
Please reassure yourself which one matters.

Because
horizontal frequency: Pixelclock / number of pixels per line
vertical frequency    Pixelclick / total number of pixels
both including the invisible pixel that make the time for
the
backtravel of the e-ray in CRTs.

This gives:
horizontal: 112 MHz / 840 = 133 kHz
vertical:   112 MHz / (840 x 640) = 208 Hz

More than 200Hz vertical frequency or refresh-rate, I don't
think
many monitors out there can follow that quickly.

horizontal: 100 MHz / 1408 = 71 kHz
vertical:   100 Mhz / ( 1408 x 796) = 89 Hz

If you add about 5% for backtravel and assume progressive
mode (i.e.
non-interlaced as in TVs)  that backs up what is initially
stated, you will always end up around 72kHz horizontal.

Okay, so the requirement clearly applies to horizontal
frequency.

Having two different vertical frequencies (refresh-rates)
for one
resolution would work with adjusting the time you allow for
vertical
backtravel because the time you spend per line is fixed by
the 72kHz
horizontal requirement of your monitor.

There is some good and short documentation for xfree what
the modeline
means and how it translates to the "physics" of
the device,
and how to construct modelines for specific requirements
with that
knowledge.
I don't have a link available right now, though.

Hi

That modeline didn't work... and non-root users can't use
X...
Is there any other open source operative system who are
easier to work with?
Feels really messy and fuzzy with everything in the macppc
port, maybe
it's a port for the elite and not for the common people
interested in
using an *BSD on their mac?
