[9fans] vesa success list

[Russ Cox]

If you have a vga card that works with vesa,
especially if it doesn't work without vesa, please
add it to the wiki page [supported PC hardware]:
http://plan9.bell-labs.com/wiki/plan9/supported_pc_hardware/

Thanks to Dave Eckhardt for the suggestion.

On my Thinkpad 600X(Neomagic NM2360, MagicMedia 256ZX) I get a blank
screen, tried the 800x600x8 and 1024x768x16 resolutions with the same
result.

The neomagic driver doesn't work properly with this card: the image is
displaced right and to the bottom and what is off the screen shows at
the top but with strange artifacts and noise.

With vesa?

On a cold boot?  Did the neomagic driver work in the old
kernels?

Sorry for not being clear enough.

No, it had the same problem.

Note also that I'm using the 'bootable' option of the CD, which I hope
has the same kernel as the installer.(Now tested the installer with
identical results).

It's a different kernel but the same drivers.  What differs is
how the kernels goes about attaching to the root file system.

The vesa blank screen is mostly undebuggable.
Some cards just aren't going to work with our
vesa implementation.

You should be able to get the neomagic driver working though.
The source is in /sys/src/9/pc/vganeomagic.c and
/sys/src/cmd/aux/vga/neomagic.c.  It's probably just a register
or two being set wrong.  There are some with Offset or
Center in their names.  I'd try those first.  I'd also try
the native LCD resolution at 8bpp and then move on
to higher depths and higher resolutions (in that order).

This doesn't seem to be necessarily Plan9 problem, because I have a Neomagic
in a TP 570 (will find the exact NeoMagic Nr. momentarily), and it blanks
with certain modes of X (from OpenBSD) and all modes when returning to text
mode from X. Did you have a problem with this card on another OS too?

Nietzsche's first step is to accept what he knows. Atheism for him goes
without saying and is "contructive and
radical". Nietzsche's supreme vocation, so he says, is to provoke a kind of
crisis and a final decision about the
problem of atheism. The world continues on its course at random and there is
nothing final about it. Thus God
is useless, since He wants nothing in particular. If he wanted something --
and here we recognize the traditional
forumlation of the problem of evil -- He would have to assume responsiblity
for "a sum total of pain and inconsistency
which would debase the entire value of being born."

i've got a thinkpad 570 with a neomagic chipset that works perfectly with gentoo 
linux and X11. (after recompileing everything. the live cd assumes a pIII.)
although i haven't tried anything other than 1024x768x24.

man, that is one painful compile!

Try 1024x768x32 instead. When using aux/vga -m vesa -p I did not
notice any settings ending with x24.

That's funny...just before the recent chunk of changes a student
and I were poking at a Dell laptop with, I believe, the same
NeoMagic card (it has an integrated sound device, right?).

That's exactly what we observed.  I tried an April VESA kernel and
while we did get a blank screen that wasn't the whole story--in
addition, the kernel was no longer running.  It also locked up if
I tried to use aux/vga to "switch to" text mode.

Is anybody happily using this chip with Plan 9 in any machine?

Re: [9fans] vesa success list

[erik quanstrom]

on second thought ... i remember having similar problems with my 570 & X11.
the solution for me was declaring the right amount of video memory. iirc declaring
to little memory resulted in a shifted image. declaring too much required removing
the battery.

My 570 works perfectly with Plan 9 using the native driver.
It doesn't work with the vesa driver, however, the system goes
out to lunch.

Don't know about the VESA, but the neomagic driver worked in the old
kernels with my Thinkpad 600X. Just  required the screen been set to
1024x768x16 and a press of fn + F8 keys at the rio startup.
