[9fans] WYSE Winterm 9150SE graphical problem

[David du Colombier]

Hello,

I have a WYSE Winterm 9150SE [1]. It is a terminal
running a AMD Geode GX processor, with 256MB of RAM.
It is meant to run Windows XP Embedded, wich is located
into a 256MB ROM, but it can also boot from network
via PXE.

Using PXE, I am successfully running a Plan 9 terminal
to my Plan 9 authserver. The text interface is running
fine. However, I cannot run the graphical interface.

When I try to launch aux/vga, the screen turn to blank
and displays "no input signal".

I tried dozens of modes, from 640x480 to 1280x1024, using
8-bit to 32-bit of colors, and no one seems to work.
I also tried CRT and LCD screens.

Windows XP Embedded is running fine using 1024x768x16.

I uploaded the result of 'aux/vga -p' [2] and
'pci -v' [3] on my WYSE, connected to my authserver.

How can I make the graphical interface working?

Can you say more about what you are doing to try a given
configuration?

At first glance it doesn't seem like there is a native
Plan 9 driver for your graphics chip, so if the VESA
driver doesn't work you might pursue getting a data
sheet and seeing if it looks enough like some other
chip.

I tried xga, vesa, multisync and other modes.
The result is the same, my screen become blank
and displays "no input signal".

I many cases, the graphical interface does not refuse
to start, like when the chip is not supported, but displays
a blank screen. I had never seen that before.

My chip does not seem to be supported by VESA driver.

What can I try to change in the VESA driver?

Can you say exactly what you mean by "tried xga" and
"tried vesa"?

I modified the lines "monitor=" and "vgasize=" in the
plan9.ini of the WYSE, located in /cfg/pxe/<MAC address>
on the authserver, then I rebooted the client.

I also tried to run aux/vga when the client was running.
