Bug Description

ubuntu amd64 version, nvidia card.

After few days, Xorg memory usage grows to around 500 MB (!).

If I log out and log in into my kde session, then still around 400 MB are used.

When I fully reset Xorg (ctrl+alt+backspace zap) then the 400 MB are freed, and when I log in again then this time I have 400 mb more ram free.

Since only resetting Xorg fixes this (killing firefox, nor re-logging into my session doesnt hlep) then it looks like Xorg bug (and/or the driver).

I use nvidia closed driver installed via Ubuntu.

Not sure if this is a dupe of that bug. This is about Xorg showing increased memory usage and the other is about the nvidia driver leaking texture memory in the compiz process. I don't think Xorg uses GLX_EXT_texture_from_pixmap internally.

Hi limcore,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

The output of lspci -vvnn would also be worth having.

I'm also affected by this bug. I looked at it some moths ago and it seemed to have something to do with kdf/libpoppler.

Since I installed Intrepid and I'm back to using poppler (through okukar), it has been happening again.

I was wrong, it is not a duplicate of bug #195183.

Furthermore I solved it by disabling Xinerama:

Option "Xinerama" "false"

in the ServerLayout section of xorg.conf
