[Bug 725434] Re: Nvidia drivers lead to extra memory usage for each process using libGL
The fix for this has been available for a long time, if it works - can the cairo gl backend be re-enabled?It's been disabled for nearly 3 years now, in the meantime it is available on fedora. This is affecting an app I maintain as I can't use it with cairo-gl for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/725434 Title: Nvidia drivers lead to extra memory usage for each process using libGL To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cairo/+bug/725434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I know this is old and most of you must be running 11.10 now, but I just installed 11.04 and I'm having this problem. The last version of libcairo2 in the repos is 1.11.3, which gives me a ram usage about 1.5Gb just after login. I've forced version 1.10.2 and everything is fine now, ram under 500Mb. Another problem I noticed is some apps don't close properly with the latest libcairo2. I have a transparent gnome-terminal set as desktop background and if I close it (with right click, exit command, or even xkill) the process remains in top using ram). Also that prevents me from logout or reboot the system (it keeps telling me than some apps refuse to close). Don't know how is this related to the graphic drivers but forcing the older libcairo2 solved it. If somebody is still taking care of this bug, can you tell me if there is a more stable solution other than maintain an older package frozen?

It's really worrying that noone is the assigner of this bug, when we are nearly reaching the release day...

Summary of what was discussed and tested: * shipping a libcairo2-gl which would conflicts,replaces,provides libcairo2 wouldn't work since provides are not versioned and that wouldn't satisfy the dependencies of most of binaries dependy currently on libcairo2 - we need a new binary installable at the same time as libcairo2 and tweak ld paths * the rules was updated to add a gl build flavor, it means cairo get built without gl and and an extra time with gl * copying the gl build library in a new directory, that would work for runtime but is not enough for builds since the .pc and the .so don't point to the right variant, building with gl also creates some new cairo-gl.pc which need to be installed - we need a libcairo-gl-dev binary, the binary needs to be installable at the same time than libcairo-dev due to the same reason than the library (the provides are not versioned which would mean it can't be installed as a replacement) * installing only the extra .pc in a different path wouldn't work since that would lead to inconsistencies in the cairo installation - the standard path needs to be used for those .pc * If the .pc don't point to the right directory to build with gl it would mean wayland softwares that need cairo-gl would need hacks to point to the right directory * The libcairo-gobject library should build with the correct variant to avoid have 2 different libcairo be loaded by libcairo-gobject users so we would probably need a libcairo-gobject-gl as well The work starts being non trivial from there and it will lead to a solution that need hacks in softwares that want to use cairo-gl, does anybody has a better suggestion on what to do next? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/725434 Title: Nvidia drivers lead to extra memory usage for each process using libGL -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
