Xorg hangs at "Loading extension NV-GLX"

[mirza.m]

Hi,

I have two 7600GS cards with different Xorg servers running on these cards:
1. twinview with beryl
2. only tv-out

2nd X server is being started (with -sharevts) when I log in and it is working great.

Problems appear after waking up from suspend:
1. X server on the 1st card with twinview is working great
2. X server on the 2nd card is still running, but there is no picture on the TV after waking up

So I decided to kill 2nd X server before suspend mode and restarting it after waking up.

But X hangs (cpu running at 100%) after restarting at this line:

(II) NVIDIA(0): Setting mode "800x600"
(WW) NVIDIA(0): WAIT (0, 1, 0x8000, 0x000005c0, 0x000005c0)
(WW) NVIDIA(0): WAIT (0, 3, 0x8000, 0x00000af4, 0x00000af4)
(WW) NVIDIA(0): WAIT (0, 11, 0x8000, 0x00000b14, 0x00000b14)
(II) Loading extension NV-GLX

I waited for a minute, but nothing happened. Killing/restarting 1st X server resolves the problem. But this is not a solution, because it kills all my applications.

I hope to get some of the great comments from netllama or some other specialists to resolve this problem. I am using 1.0-9755 with kernel 2.6.21.3.

Thanks a lot.

Am I asking strange questions?

Nobody with an idea what might be going on?

I'd suggest reading the forum sticky posts.

[mirza.m]

You are talking about "If you have a problem, PLEASE read this first"?

I hope so ... Here is the nvidia-bug-report.

I had to gzip it because it is pretty big.


I added also the log of Xorg.1.log at the of the regular nvidia-bug-report.log, because that is the log file of the 2nd Xorg server (started with -logverbose 6). I can split it in two files if you want.

I hope you have an idea, what is going on.

Thanks a lot.

I don't see any issues with NV-GLX in your bug report.

Also note that 1.0-9755 is no longer supported. You should upgrade to 100.14.09 if you're still having problems.

[mirza.m]

OK, I will upgrade.

I don't see any issues with NV-GLX in your bug report.

Do you see at the end of the log file, how to 2nd X server just stops at "Loading extension NV-GLX"?

It stops there and cpu is running with 100%. X does not get started, and none o of the commands from xinitrc does not start.

Sorry, I had missed that you appended the 2nd X log to the end of the bug report. In the 2nd X log, I see several WAIT messages, which can be triggered when the nvidia driver is mpt receiving interrupts from the graphics card. This could be a driver bug, or it could be a bug elsewhere (X server, kernel, BIOS, etc).

Please retest with 100.14.09, and if the problem persists, please verify:
0) That you're using the latest motherboard BIOS
1) Whether the problem persists if you run one X server for both GPUs

thanks,
Lonni

retested ... same situation

I am not using latest motherboard BIOS, but I will update tomorrow. I also tried with swapping two cards (I moved 1st card in the PCIe slot of the 2nd card and 2nd in the 1st slot) but no changes.


Back to the root of the problem. As I told in the 1st post:

2. X server on the 2nd card is still running, but there is no picture on the TV after waking up

So I decided to kill 2nd X server before suspend mode and restarting it after waking up.

The problem with these WAIT messages appear only if I (after waking up from suspend) kill the 2nd server and start it again. It does not appear when I start it first time (before suspend). But as I told, after waking up, there is no picture on the TV. That's why I kill 2nd X server and start it again.


But when I start X first time (before suspending), I get these messages, but only on the 2nd X server, not on the 1st:

(II) NVIDIA(0):
(II) Loading sub module "int10"
(II) LoadModule: "int10"
(II) Reloading /usr/X11R7/lib/modules/libint10.so

(EE) NVIDIA(0):     be restored correctly on your TV.
(++) NVIDIA(0): DPI set to (100, 100); computed from -dpi X commandline option

Is/Could this be a reason for no picture on the TV after waking up?
Is int10 being used only for TV? I am asking this because I do not see the message Loading sub module "int10" when I start 1st X server on the 1st card. I see it only when I start 2nd X server on the 2nd card.

Thanks a lot.

[netllama]

Yes, int10 is normally only needed for TVs. Based on the latest information, it looks like the problem here is outside of the nvidia driver.

[mirza.m]

Suggestions? Reinstalling/recompiling X server?

M.

[netllama]

Its not clear where the problem is. It might be a kernel or BIOS bug, it might be Xorg. All that is clear to me, is that the first fatal error is not coming from the nvidia driver.
