Ok, this may be the problem. The first one is initialized by the pm2fb,
while the second is not. This mean either some initialization problems,
or the fact that X doesn't initialize some values set by pm2fb.

Sound sreasonable.

Yep. It probably doesn't happen on x86, since the int10 stuff
initializes the card with the onboard bios. Using a x86 emulator in X to
run this bios might be a solution.

What kernel are you using, maybe it would be best to work on a 2.6
kernel and try to adapt the pm2fb to the new framework or something.

Currently using Herbert's 2.4.24-1.  I tried various 2.6 kernels prior
to 2.6.1, but xdm couldn't seem to start the server and the USB HID
drivers didn't seem to be functional.

Mmm.

Can you describe me the symptoms again ? what exactly did you see on the
second head ?

The second head is currently running WindowMaker with the default Debian
background.  In the upper left corner, there is the 1/Main clip.
Directly to the right of that (I assume by 64 pixels or so) is the exact
same 1/Main clip.  In the border between the two are some flickering

Ho. definitively some registers who are bad. It has been a long time
since i have looked at the pm2 specs (kind of 98ish i think) though.
Maybe you could get hand of the free TI-pm2 specs and look for yourself ?

You would dump all the possible registers, and see which one is
different. Enabling debugging in the glint driver would also do. You can
safely run no-accel on these for the tests, as this is definitively not
an accel issue, but a video out/ramdac one.

white lines.  The rest of the screen is filled with horizontal
flickering black and whitish lines.  The left edge of the swirl is on
the right hand side of the screen.  It appears 5 times.  The "debian"
only appears as "de", though there are about 5 d's and 3 or 4 e's,
overlapping.  The clips themselves look perfect, but nothing else does.

Any color problem ?
