I finally got my Picasso II card and now I want to set it up
for use under NetBSD 1.0. I grabbed the experimental Picasso
driver from ftp.uni-regensburg.de and installed it. When I
boot with the new kernel the usual messages appear and the
Picasso is recognized. The screen seems to switch to the
Picasso for a second when it is recognized and then back
to the Amiga display (this is ok,right?).
After I log in I start X with:
startx -- -mode 4
According to the docs and the source this should give me
a 640x480 screen with 63Hz at 31kHz. But all I get is a screen
which my monitor doesn't seem to be able to sync to (I have
a Nec Multisync 3D). When I toggle the display with the "toggle"
utility I get back to the amiga display which is filled with the
X pattern (the one you usually see when X starts up in mono mode).
On the Picasso display I can see the XTerm window and XClock,
but the display is all distorted because the monitor doesn't sync
correctly. I was able to exit as I normaly would (selected the "Exit"
menu of twm). Then I get back to the amiga display but it is still
filled with the X pattern and I can't type anything and I have to
reset the computer.
I have tried different modes and mode 4 is the only one that
gives me at least something (in other modes all I get is a black
screen or some other distorted picture that is completely unusable).
I also tried patching the defaultmon variable of the Picasso
driver but I get the same results as if I start X with an
explicit -mode switch.
So - can anyone PLEASE help me with this? Have I done anything
Here's my setup:
SW: NetBSD 1.0, Picasso driver version 2 from uni-regensburg,
using Xamiga24 from uni-regensburg
HW: Amiga 2000, IVS Vector accelerator (68030 @ 25MHz), 8MB
RAM on the Vector, another 4MB on a GVP Series II controler
(the 4 megs are not used by NetBSD), Quantum 540MB and 52MB
both connected to the Vector onboard SCSI
The Picasso and my NEC 3D work just fine under AmigaDOS in
all resolutions (640x480, 800x600, 1024x768, ...). The Nec
can display horizontal frequencies from 50-90 Hz and vertical
frequencies from 15.5 kHz to 38 kHz.
Thank you in advance.
