Making a VNC server for A/UX

[robin-fo]

Can you run newconfig -v and tell me the results? And preferably the output of 'dump_modules /unix', too?

Oh, that's easy, I've buggered something up :-D I'll upload a new version shortly...

 

[cheesestraws]

@robin-fo can you try this instead? Also, can you send me a copy of /etc/RELEASE_ID?

 

[cheesestraws]

(oh, and if you're running this in QEMU, it doesn't work properly: I haven't worked out why yet)

Weird. I wonder how my kernel ended up with a memcpy and yours didn't. Either way, try that tarball

 

[robin-fo]

The kernel driver works now, I can connect, control the UI, but the remote screen stay black... I can no longer use the mouse in QEMU

There's something that doesn't work properly with the video in QEMU. I haven't worked out why yet :-(. That's the results I got, too.

ok thanks, I'll try with my 700

I suspect what's happening with QEMU is that it isn't returning the palette in use on the display properly, but I haven't seriously looked at it yet.

 

[cheesestraws]

Look here: the read function never returns the LUT but the write function can write to it. https://github.com/qemu/qemu/blob/1416688c53be6535be755b44c15fb2eb9defd20f/hw/display/macfb.c#L522

So it returns 0 for every colour, resulting in a black screen I think.

on the real Quadra, I get a segmentation fault soon after connecting

accepted VNC connection from 192.168.2.4, starting session...
Segmentation fault (core dumped)

[robin-fo]

Here is the generated "core" dump

 

[cheesestraws]

Thanks! I'll have a look to see if I can make any sense out of that. If I were to send you a version with added debug output, would you have time to run that for me? I'm not going to have time myself to get out one of the 700s and A/UX that up until after Christmas now...

Won't be much better on my side, except If I get it before I go to bed tonight

 

[cheesestraws]

Oh, what screen resolution are you running at?

 

[robin-fo]

Oh, what screen resolution are you running at?

IIRC 1152x870

 

[cheesestraws]

and 8-bit colour?

 

[robin-fo]

Possibly 24..

 

[cheesestraws]

Could you check that? It ought to complain and bail out politely if it's getting 24 bit colour, because it won't work on anything > 8 at this stage... but crashing isn't totally outside the bounds of possibility.
