Fedora Core 4 : kernel 2.6.12.1
1. Single Matrox AGP 32MB G400 Dual Head.
All I get is one head. That's it. The other head is black.
2. Single Matrox AGP 16MB G450 Dual Head
From power on all through boot up, the two heads put out exactly the =
same image.
3. Multiple Matrox PCI (Millennium I, II & Mystique)
Beautiful! Works exactly like it should. PCI slot #1 is fb0, #2 is fb1, =
etc. I have 4 different versions of Matrox PCI cards working at the same =
time with a PCI network card.
4. Single Matrox AGP 16MB G450 Dual Head + Multiple Matrox PCI =
(Millennium I, II & Mystique)
From power on all through BIOS and into Linux boot up, the two heads on =
the G450 put out exactly the same image and are the primary display. As =
soon as Tux appears, he's on the first PCI Matrox card and the Linux =
boot continues with that as /dev/fb0. The AGP card is /dev/fb1 and =
additional PCI cards are 2, 3, etc.
5. Single Matrox AGP 32MB G400 Dual Head + Multiple Matrox PCI =
(Millennium I, II & Mystique)
Just one head on the G400 and it is the primary boot display. As soon as =
Tux appears, he's on the first PCI Matrox card and the Linux boot =
continues with that as /dev/fb0. The AGP card is /dev/fb1 and additional =
PCI cards are 2, 3, etc.
There is something else that is a little bit annoying. Every time I =
switch out the video cards, Linux boots up into X. I have a '3' at the =
end of the boot line in grub.conf to enter run level 3 and that works =
every time except for the first time I boot up with a different video =
card. Once I log in to X as root and wait for it to come up I have to =
ctrl-alt-backspace to get out to a shell prompt, where I have to log in =
as root again.
I will try all of this on another machine in Red Hat 9.0 with whatever =
2.4 kernel is sitting there and let you know.

If you want to use more than one video card then that implies that you =

need at least one that is PCI. I have had success using 5 Matrox PCI =3D
cards (all slots full).

I never heard of an S3 Trio that came with a sufficient new VESA driver to work
with vesafb. Which of course doesn't mean that no such beast exists...

James,
Thanks! I do have one multihead video card, the GeForce Ti 4200 AGP.
It works
with Mandrake and X but only one screen with FrameBuffers.
What boot parms are you using? I use:
title Fedora Core (2.6.12.1VESA)
root (hd1,0)
kernel /boot/vmlinuz-2.6.12.1VESA ro root=/dev/hdb1 rhgb
vga=0x31B video=rivafb
I have to use 'video=rivafb' to get the NVidia driver to install FB.
Do I need to add 'map=???'?

The Ti 4200 should be recognized by nvidiafb. The MX 4000, I'm not sure (what is the pci id of that card?). For S3 Trio to work, configure it as your primary card and use vesafb to drive that thing. Use nvidiafb to drive the Ti 4200, and depending if the MX 4000 is supported, probably nvidiafb or rivafb. The nvidia cards will be /dev/fb0 (and maybe /dev/fb1), and the S3 Trio will become /dev/fb1 (or maybe /dev/fb2). Check /proc/fb to find out. Tony PS: Non primary cards are not initialized by the BIOS, so it might be necessary sometimes to boot the secondary cards before loading the fb driver. |

I did report it back - intelfb has bug(s), one of which is known (ioremap) and can be fixed by reverting a patch, the other one (cursor died) is not clear, maybe a hw / BIOS problem. Switching to vesa and setting vga= kernel boot parameter allowed me to boot with a fb console and to start X over fbdev. Interestingly, booting with vga=ask and performing a scan doesn't deliver desired modes. What helped was this suggestion by Antonino A. Daplas: > One good method is to use the "vesa" driver of Xorg/Xfree86.

This is, however, no longer important to me, as I now don't need the fb anymore - I can use touchscreen with any X card driver.

Guenndi, What Operating System are you using?? I have been trying to get FB working on a Fedora Core 4 system with little luck. I then installed Mandrake 10.1 and got the OS to see the four video cards I have but still no more than one FB. I can get four displays with X. On both of my systems, 'X -configure' does not work. It does not assign any mode statements to xorg.conf. Good luck, let us know how you come out.

EZFB has an example touch screen application that has nothing to do with X. It reads directly from the touch screen device and translates coordinates from the physical touch screen to the visible frame buffer resolution. http://www.akrobiz.com/ezfb/ Look at "tsc" James. :o) ----- Original Message ----- From: <gl...@ds...> To: <lin...@li...> Sent: Monday, September 05, 2005 4:11 AM Subject: [Linux-fbdev-users] X over fb: "EGA/VGA planes are not yet supported by the fbdev driver [1]" > Hello everyone > > Trying to get the xserver (Knoppix 3.8 XFree86 4.3.0.1) over framebuffer. > The hw is the following: > > 0000:00:02.0 VGA compatible controller: Intel Corp. 82852/855GM Integrated > Graphics Device (rev 02) > 0000:00:02.1 Display controller: Intel Corp. 82852/855GM Integrated > Graphics Device (rev 02) > > (btw, why do I get 2?)

As a follow-up to the previous thread, but not hardware-specific: where
is the screen_info.orig_video_isVGA variable set and is it user-settable?
Actually, is the test
if (FIXED_MODE(dinfo) && ORIG_VIDEO_ISVGA != VIDEO_TYPE_VLFB) {
ERR_MSG("Video mode must be programmed at boot time.\n");
cleanup(dinfo);
return -ENODEV;
}
in intelfbdev.c (2.6.13) correct? (ok, this one is hardware-specific,
maybe).
Thanks

Hi alltogether!
On the debian-powerpc and linuxppc-dev lists from time to time pops up a
subject which probably better belongs on this list since it discusses a
problem with the nvidia graphics card used in newer 12" powerbooks. It seems
it only occurs on graphics adapters with NV32 chips and newer.
Also, I did not have the problem with kernels up to 2.6.10 together with
the patch from Guido G=FCnther providing suspend-to-disk. It seeems the
problem appeared after 2.6.11 with the merge of swsusp2. To get
better data I could test the old kernels, but perhaps the following
description of the problem rings a bell to someone:
boot, suspend-to-disk from X -> crashes in the first state of suspend=20
when switching to another vt
boot, switch from X to vt[1-6], suspend-to-disk -> works
suspend-resume to/from disk works from now on under X too=20
boot, switch from X to vt8 (not allocated in inittab) -> crash
summary: directly after boot the system crashes on chvt to an to that
time unused vt.
Probably related:
If I start mol (Mac-on-Linux) the system crashes even when I try to
switch to vt1. This also means that I cannot use fullscreen mol on tty8.
Most interesting however is that I can still type "halt" or
"/etc/init.d/gdm stop" in my xterm and the machine kills X and shuts
down normally, even after running mol. I can suspend to disk "normally"
again. To me this looks as if the machine follows different code paths
in the kernel in each situation and some of them are save, others are
not.
Please tell me what I can do to debug this further, I am also more than
willing to test patches.
With best regards,
Wolfi

Hi. I was interested in looking at XFB by Hannu Mallat but a Google search returns with just a pointer to a dead web site at http://www.hut.fi/~hmallat/xfb. Has it been discontinued for newer kernel versions (2.4 and above)? |
