Memory leak in xorg.

[Volodymyr Babchuk]

Seems that xorg has a memory leak. On 28th day of uptime it consumes 13G of virtualy memory on my PC:

 PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
21516 root 20 0 13,340g 8,351g 49036 S 7,3 53,7 3387:19 Xorg

xrestop does not show anything suspicious:

Hm. I have selected "xorg" as affected package, but tracker created bug for "linux" anyways. Sorry for that. Unfortunately, I can't change affected package for some reason.

Hello Volodymyr,
Thank you for submitting this bug and reporting a problem with the xorg package. You made this bug report some time ago and Ubuntu has been updated since then.

I think this is a problem for a lot of people and they were working on it. I am not sure when the solution was to come out. If this is no longer a problem for you personally, could you let us know so that we can close this ticket?

If it is still a problem, are you still interested in finding a solution to this bug?
Also, have you upgraded to 18.04 yet?

If you have, could you run the following (only once):
apport-collect 1697929
and upload the updated logs and and any other logs that are relevant for this particular issue.

Thank you again for helping make Ubuntu better.
G

Hello gf,

This bug disappeared after one of upgrades. But I'm not certain, what exactly fixed it.
I think, it can be closed now.

Thanks for the update, Volodymyr.
Have a great day!
:)
