Ani and others :-)

	I was hoping you could lend me some insight :-)  I'm trying to do
some work with DirectFB, and I'm now running into a slight problem
concerning getting output on the VGA port.

	I've e-mailed the directfb-dev mailing list about it and had some
interesting conversations, but the end result was basically: "You should
check with Ani Joshi about that, and maybe ask on the linux-fbdev-devel
mailing list".

	So now I'm asking here :-)  Below this I'm including the
description of the problem I'm seeing that I sent to the directfb-dev
mailing list.

	Can anyone help me out?  Thanks :-)

It took me a while to figure it out what I know so far, and I'm still not
100% sure what's going on...

If I run *any* DirectFB application, the screen blanks.  The system
doesn't lock.  I can ssh in and see the application listed in the process
table.  For example, running df_fire, the screen blanks and, after a few
seconds, the monitor goes to sleep (as if it's no longer getting a
signal)...  Hitting the 'esc' key brings back the vt, just as usual when
runnin the application.

Running dfbsee produces similar results.  However, with any video that I
play, I can hear the audio stream :-)  I just can't see anything...

Now, when I first experienced this, I posted about it on either
directfb-dev or directfb-user.  A short while later, I figured out a
workaround :-)

Instead of booting with my CRT plugged into the VGA port, I used a
DVI-to-VGA adapter (that came with my Radeon 7500), and plugged the
monitor into the DVI-A port.  Lo' and behold, DirectFB applications were
now showing up :-)

Since then I've done some video card swapping and now have a "Powered By
ATI" Radeon 8500 LE.  This card has both a VGA port and a DVI-D port, but
no adapter.  The old adapter doesn't work for this card because it's
designed for DVI-A as compared to DVI-D.

I've encountered similar problems elsewhere, too.  For example, a hacked
radeon 7500 driver for BeOS would only display on the DVI port, even if
the computer booted up fine with a monitor on the VGA port.

Of course, I just don't know why this is the case :-)

I've been poking around on-line looking for a DVI-D to VGA adapter, but
very few of the shops that sell them on-line clarify if it's DVI-A or
DVI-D :-)

Radeon support (was Re: (no subject))

[Adam K Kirchhoff]

Me again,

	So I think I might have a better idea of what's going on... I did
some testing with the Radeon framebuffer tonight, and can only seem to get
it to work with just two modes: 1024x768@70 and 640x480@60.  I've tried a
number of others, which worked with the DVI output of my 7500, but don't
seem to work with the VGA port of the card.

	Any ideas?

Re: Radeon support (was Re: (no subject))

[Adam K Kirchhoff]

Alright, so I did some more testing this morning...  I tried the exact
same modes, with the exact same monitor, first hooked up to the VGA port
and then hooked up to the DVI port of my Radeon 7500...  All but two of
the modes were taken from the fb.modes file supplied by the DirectFB
project.  *None* of the following modes (all at 16 bit) worked with the
VGA port:

640x480 75Hz
800x600 75Hz
1024x768 72Hz
1280x1024 60Hz
1600x1200 60Hz

All of the above worked (again, with the *same* monitor) hooked up to the
DVI port.

The two modes that *did* work with the VGA port were modes that I
specified to the kernel when booting (they were not taken from fb.modes):

1024x768 70Hz
640x480 60Hz

Also, it makes no difference if I use one of the unsupported modes from
the list of five above with fbset or when the kernel boots...  In both
situations, the display just blanks, as if it's either: A) getting no
signal, or B)  getting sent to a frequency it doesn't support.

Does *anyone* know what's going on and how to fix this?

Well, I finally got it working...  I had to use the radeon framebuffer
code that's distributed with mplayer, though :-)

Re: Radeon support (was Re: (no subject))

FYI, using the radeon framebuffer code from the mplayer package seems to
have resolved the issues I was having.  Any chance of the mplayer driver
making it's way into the kernel?

Radeon support (Was: Re: (no subject))

[Adam K Kirchhoff]

I thought that might be a possibility, too, except that the same monitor
works with the same applications when connected to the DVI output on the
7500 with the adapter.  So apparently the application isn't switching to
an unsupported frequency.

I might try to get the app to dump the registers anyway, though.

Thanks for the response.

Oh, and sorry for sending an e-mail without a subject to the list.
