xorg-server memory leak

Re: xorg-server memory leak

If nvidia-settings brings up the nvidia Xorg control panel, and shows your display correctly, then yes you are running with the nvidia driver.

Does that error output always show the same 3 memory addresses? Since it says "not released memory pool", I'm inclined to think it is a feature of your motherboard/BIOS design, rather than anything about Linux. There's a similar "feature" on my Intel motherboard -- a boot warning regarding memory reservation, but it's irrelevant to running the system.

The other thing to do is just to let your system run for a few days, and see if there is any evidence of any kind of degradation. Linux will tend to "use up" memory, mainly for disk cache, in a way that is unnerving for folks whose main experience is with Windows. But in Linux, it's a good thing to use your memory in a productive way. When you start an application or start copying files around or something like that, it should re-adjust the memory allocation to let you work productively, and as long as it does that, you do not have reason for concern.

Thanks dibl!

No. The addresses are different.

I will leave Lucid running for a few days and check my memory usage.

Re: xorg-server memory leak

Hi guys, I landed here after a google-search, so I hope this is the right spot for this issue. Basically, since I fresh-installed kubuntu RC, the Xorg process shown in System Monitor keeps eating up memory. I've read a fix has been issued, but nothing changed at this end. Currently, Xorg is at 894.0 and counting, and no application closed seems to have any relevant effect. I don't have a Nvidia card, but a Matrox 450, so I'm not using nvidia drivers. Also, following the tests I've found in this page, I got this result:

lelamal@EGO:~$ grep "object bytes" /sys/kernel/debug/dri/0/gem_objects
grep: /sys/kernel/debug/dri/0/gem_objects: No such file or directory

and this:

lelamal@EGO:~$ free
       total    used    free   shared  buffers   cached
Mem:    2060876  2008996   51880     0   11960   361208
-/+ buffers/cache:  1635828   425048
Swap:   2496504   278364  2218140

There is obviously something terribly wrong, but I don't know how to fix it. Is it a graphic card specific issue, or is something else which is being addressed?

Thanks for the link, Fintan. Indeed, my GLX version is 1.2, and had swappiness level at a default 60 value. Now it's set to 10, and I will keep monitoring Xorg behaviour.

Re: xorg-server memory leak

If your lucid has been slowing down and become sluggish lately (like mine) this may be the reason:

With a partial fix here:

https://wiki.ubuntu.com/X/Testing/GEMLeak

Hope this is useful

I just want to ask some very very simple. How can I install the patch? Because, I need the patch for intel video card. Currently i have the 2.9.1 version of xserver-xorg-video-intel but the patch it's in the ppa is 2.9.0-1ubuntu2~xup~3.

My problem it's Kubuntu uses Kpackagekit for install the updates and it just takes the lastest version of each package and i haven't found how to force a downgrade for the patch.

Thanks for any help.

Best Regards

Quote from here:
https://wiki.ubuntu.com/X/Testing/GEMLeak

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get dist-upgrade

Please verify that:

glxinfo | grep "GLX version"

says "1.2", not "1.4"

Re: xorg-server memory leak

ok i think that my start was very bad because

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
[sudo] password for mikesol: 
Exception in thread Thread-1:

Ok i added the repo manually, no problem.. but

~$ sudo apt-get update

I tried with pkcon, and it can connect to internet but it seems that just take the lastest version 2.9.1(with the bug) instead of 2.9.0

Thanks

Re: xorg-server memory leak

I think mine got fixed

befor when I would do

vinny@desktop:~$ grep "object bytes" /sys/kernel/debug/dri/0/gem_objects 
213168128 object bytes

the # would just keep growing untill it wint to -#'s witch the report sead ment multipull Gig's of loss

now after a X-sever-core update 2 days ago the reported number has gone as high as 290000000 or so but will drop back ...... then up then back and fluckuats like that .........intel chip's hear.

so I assume the mem is being relesed and not lost.
