GF4 Ti4600 w3123, nothing but a blank screen

[kairo692000]

I recently bought a Ti4600 to use with another computer I bought. I
already own a GF3. When I try to start up the X server all I get is a blank
screen (text mode works fine). There are no error messages of any
kind. I have this hooked up to an LCD monitor using the DVI connector.
To rule out the monitor/DVI I hooked it up to my other monitor which
is currently hooked up to GF3. Still nothing but blank. If I use the analog
connector I get some noise on the screen (random characters).

I am using SuSE8.1 w/2.4.19. I have disabled AGP to rule that out as well.
The chipset is an SiS 651, and I compiled the kernel modules myself. Has anybody had luck with this combo? The card does work great in text mode, but I would like to see its grx capabilities. Thanks for any help.

:confused:

Is there anything in either /var/log/messages (dated recently) or in the output of dmesg that talks about unsupported AGP? Or about agp_try_unsupported?

[kairo692000]

Yeah. dmesg says that it is unsupported, but I was hoping that by disabling
AGP I would get around this until it became available. Will this prevent it
from working at all? :eek:

What about NVidia AGP support? Here is some info from /proc. It looks
like it is somewhat recognizes it. I will try turning on NV AGP support and
see what happens.

brutus:/ # cat /proc/driver/nvidia/agp/card
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x00000000

brutus:/ # cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: SiS (unknown)
Fast Writes: Supported
SBA: Supported
AGP Rates: 4x 2x 1x
Registers: 0x1f000217:0x00000000

brutus:/ # cat /proc/driver/nvidia/agp/status
Status: Disabled

brutus:/ # cat /proc/driver/nvidia/cards/0
Model: GeForce4 Ti 4600
IRQ: 11
Video BIOS: ??.??.??.??.??
Card Type: AGP

brutus:/ # cat /proc/driver/nvidia/version
NVRM version: NVIDIA Linux x86 NVdriver Kernel Module 1.0-3123 Tue Aug 27 15:56:48 PDT 2002
GCC version: gcc version 3.2

[kairo692000]

Yeah that did it! :D

I now have it coming up, but I don't think it is using AGP acceleration.

brutus:/ # cat /proc/driver/nvidia/agp/status
Status: Disabled

But it at least comes up. Any speculation on, if and when this
chipset (SiS 651) will be supported by NV. ;)

Thanks for the nudges, I was about throw in the towel.

I have the same problem, could u please tell me exactly what to do to get it running?

[bwkaz]

I believe the easiest way is to add a line to /etc/modules.conf

Make the line look like this:

options agpgart agp_try_unsupported=1

That seems to work for this chipset, anyway... no guarantees if you're running any other one.

[kairo692000]

Yeah, I tried that last night and it works. Now to try tribes2.

brutus:~ # cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: AGPGART
AGP Rate: 4x
Fast Writes: Disabled
SBA: Disabled

One thing I have noticed is when I exit X it nevers returns to text mode.
I have to reboot. This might be the DVI connection I am using, but I am
not sure. The monitor says "No Signal" and goes black. Have you seen anything like this? This happens with both NVIDIA AGP, and AGPGART.

[bwkaz]

I believe I have seen (well, more accurately, heard about -- I haven't had it happen to me) it. But I don't know what to try to get it to work...

First question is always "are you using rivafb for your console framebuffer support?", and if the answer is "no", I don't really have anything that might work.

[kairo692000]

No rivafb here. Thanks for help! :D
