[SOLVED] Nvidia graphics, xorg memory leak since kernel 4.19.2

[dibl]

I have 4 siduction systems, only 1 has Nvidia graphics -- the others are all Intel graphics.  The one with Nvidia graphics is using the nvidia-driver.

On the system with Nvidia graphics, I have been seeing a serious memory leak since at least the 4.19.2 kernel -- possibly it started earlier.  The culprit is xorg.  The platform has 32 G of memory, and if I let it run overnight, in the morning it will be starting to swap, and the problem process is xorg.

Does anyone else see this issue?

Which nvidia driver are you using?

I cannot reproduce this with experimental 396.54-2

The only thing I can find is

https://devtalk.nvidia.com/default/topic/1043938/nvidia-geforce-4xx-series-drivers-segfault-with-kernel-4-19-x/

But not related here (driver wise)

Is that v. 396 driver in the experimental repo?

Here's a picture.

Yes 396.54-2 is in experimental

OK, fully updated, Torsten's latest kernel installed, and the 396 Nvidia driver from experimental.

I will let it run overnight and see what I have in the morning.  Thanks, piper!

No problems dibl, good luck

You see the problem?

[piper]

I'm wondering if he has a

in

/etc/modprobe.d


I always just do a

apt purge xserver-xorg-video-nouveau

But, I don't recommend that to newer users

[dibl]

Thanks towo -- I was a little too fast with the driver from experimental, and forgot the mesa packages.  Does this look better?

I do have the nouveau driver blacklisted and the package is not installed -- thanks piper.  Now that I fixed the OpenGLX version situation, it will take some time to see if the memory issue is fixed.

[piper]

I question the "blacklist thing" only because what I read at opensuse to a few people

No, that's even wrong!
Your path to the right glx lib seems to be wrong. After a look in the changelog of the nvidia driver, there was a packaging error which sould be fixed in 296.87-3

Revert move of libglx.so to /usr/lib/nvidia/current/modules.

I switched to ATI, so i can't investigate fourther.

What I would do first

Code Select Expand

apt purge nvidia.

Yes, use the period  .

Code Select Expand

apt update; apt install nvidia-driver nvidia-driver-libs nvidia-settings nvidia-smi nvidia-kernel-dkms -t experimental

If you don't need/use thermal monitors you don't have to include nvidia-smi

Post back if this don't work

[dibl]

Great -- thanks guys.  I knew something is wrong -- xorg continues to slowly suck up memory, even when no user packages are running.  I will try these ideas.
