Bug 150246

Hmm, sounds critical. Could you provide more information of the
system ? how many cards, what kind of cards. The information from
sax2 -p ?

Thanks

sax2 -p
Chip: 0  is -> VESA Framebuffer Graphics       00:09:0 0x1102 0x0002 PCI fbdev
Chip: 1  is -> NVidia Vanta/Vanta LT           01:00:0 0x10de 0x002c AGP nv

That says about my card. My card is actually RivaTNT2. Only one card.

One more point, if that is of any use, My sound card SBLIve is recognised as VGA device(strange!). And that interferes with nvidia too. 

I dont think, that is any reason, because that is not reported in any output I have tried.

Actually My sound card is being reported in windowsxp too as vga card. I have lost hope of its solution 2 years ago already. 
If there is any way to manually provide information to linux that sound card is actually sound card, not vga, I will be extremely thankful.

Thanks for the information; The problem is the wrong detected card
I assume the soundcard has PCI class 0x300 which is reserved
for VGA devices only. In such a case this is a hardware bug. You can
send me the information of 

  lspci -nvv

so I can have a look at the PCI specs

To fix your problem call:

  sax2 -c 1

which will only use Chip 1 (nv) for the config

Created attachment 67923 [details]
the output of lspci -nvv

Yes, my problem is solve and I can use now SaX2.
The output of lspci -nvv is attached .
btw, if sound card is detected wrongly, cant I manually prove that it is not vga card ?

Because of this problem I cant change to vt1-6 from Xserver when soundcard is loaded, cant even shutdown. So I remove soundcard module before I logout.
The problem is that it intereferes with framebuffer severly.

And Important point is that, the sound card class is not 0x300 .
In fact, actually, it used to work correctly earlier (2 year ago), but suddenly started identify as vga card one day in both OS.

Is this your sound card:

00:09.0 Class 0001: 1102:0002 (rev 08)
	Subsystem: 1102:8027
	Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-

	Interrupt: pin A routed to IRQ 5
	Region 0: I/O ports at a400 [disabled] [size=32]

		Status: D0 PME-Enable- DSel=0 DScale=0 PME-


if yes I can fix it :-)

Yes, that IS the sound card! TIA if you fix it :)

It's fixed now, I will submit the package today evening so hopefully
you can test with the next beta

Can you let me know the reason behind the problem? 

Does this fix means that in the next beta, My sound card will be detected and  it will not interfere with the vesafb or nvidia ?

sorry of course I will explain the fix. Your sound card has PCI
class 0x0001 which was used on older graphics cards to classify
a sub device of a primary chip. Those cards doesn't exist on the
market and even the vendors doesn't exist anymore. Therefore I
decided to remove the 0x0001 class to be a valid graphics card.

According to this your sound card will no longer be used as
graphics card under linux :-) This was the good news the bad one
is I think the PCI class of your sound card is still not quite
correct so the problem on Windows may stay.  

Thanks.
Is there any way through which I can change the class_name parameter of sound card ?
setpci doesn't work. it doesn't give any error, but still nothing happens.

What I suspect is that, when I change the class_name, the hotplug event undo the manual change. So, there should be a way to stop specific pci card to be configured via hotplug ??

setpci writes into the PCI configuration address space, be carefull
at that point. I'm sorry but I never had the need to do that and I
think I'm not of great help here. By the way it's outside of the
meaning of this bug report. I'm pretty sure you will achieve better
results on research@suse.de

Thanks
