xorg-server memory leak

[Fintan]

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

With a partial fix here:

Hope this is useful

Re: xorg-server memory leak

At first blush, this would appear to explain what I have been seeing and the timing seems appropriate. Only when I look at the finer details of the problem including the troubleshooting that is being asked, it would appear that this is an issue around compositing. For some reason I am not allowed to run with compositing on -- I just assume it's my older hardware. But this, I think, would preclude me from the testing of this particular bug fix as well as suggesting that I have a separate problem, would it not?

Re: xorg-server memory leak

I don't know. I had have my kwin effects turned off and my machine got very sluggush after a few hours.:
fintan@fintanws2:~$ grep "object bytes" /sys/kernel/debug/dri/0/gem_objects
175607608 object bytes
fintan@fintanws2:~$

Now I am reading:
fintan@fintanws2:~$ grep "object bytes" /sys/kernel/debug/dri/0/gem_objects
73207808 object bytes
fintan@fintanws2:~$

So it seams to having some effect. I'll check again in a few hours

Re: xorg-server memory leak

Now I am showing:
fintan@fintanws2:~$ grep "object bytes" /sys/kernel/debug/dri/0/gem_objects
74719232 object bytes

I started keeping this record of the bytes last night (4-22-2010) it is now 12:06PM-4-23-2010
I will keep this up untill the system dose/dosenot become unstable and post at what point
(how meney day's - the bytes count-what hapend ect,ect,) it becoms unusable!!

as of NOW it is NOT slowing down to a noteseble point .......and the onley queshtonable thing is the high load avarage??

Re: xorg-server memory leak

at up 1 day 16 and 1/2 hower's bytes now at......

vinny@desktop:~$ grep "object bytes" /sys/kernel/debug/dri/0/gem_objects
1201147904 object bytes

vinny@desktop:~$ grep "object bytes" /sys/kernel/debug/dri/0/gem_objects
1473843200 object bytes
vinny@desktop:~$

and vid is starting to get chopey if I have say bangrang runing full screen and activate the cube.
normaley it will play just fine like that.........and load avrages are going way up......1.88 as told by top (it should be around 0.08-0.18)with just bangarang and firefox runing

I'd say at miner inconvenyence stage ........

Re: xorg-server memory leak

Okay:

fintan@fintanws2:~$ uptime
21:27:59 up 14:28, 1 user, load average: 1.06, 1.08, 1.10
fintan@fintanws2:~$

then:

fintan@fintanws2:~$ grep "object bytes" /sys/kernel/debug/dri/0/gem_objects
74014720 object bytes
fintan@fintanws2:~$

Stable for now

Re: xorg-server memory leak

grep: /sys/kernel/debug/dri/0/gem_objects: No such file or directory

?

Did have the memory leak, though... was up to 600-700 MB when I noticed. I installed the xorg from aforementioned PPA and it went away.

Re: xorg-server memory leak

grep: /sys/kernel/debug/dri/0/gem_objects: No such file or directory

Unless you mistyped above, it's:

grep "object bytes" /sys/kernel/debug/dri/0/gem_objects

[abalone]

Re: xorg-server memory leak

Not mistyped. I don't have a /sys/kernel/debug/dri.

[dibl]

Re: xorg-server memory leak

Yep, me too:

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

there's no "dri" directory under /sys/kernel/debug:

dibl@lucid:/sys/kernel/debug$ ls
bdi gpio hid kprobes mce pktcdvd sched_features tracing usb x86

Re: xorg-server memory leak

Not mistyped. I don't have a /sys/kernel/debug/dri.

Ah. But, you still have to include the quoted search "pattern" for grep.

Re: xorg-server memory leak

I did; there isn't anywhere for grep to grep...
