Public bug reported: I've downloaded the latest xfwm 4.13 with XPresent support from this ppa https://launchpad.net/~xubuntu-dev/+archive/ubuntu/experimental , but it did not work. Instead I got this error: (xfwm4:712): xfwm4-WARNING **: 14:40:45.838: Dismissing XPresent as unusable, error 3 for request 148.
The problem seems to be caused by XPresentPixmap() throwing a BadWindow error. I've found an older post talking about the same issue here https://lists.x.org/archives/xorg-devel/2017-June/053874.html . They suggest that the issue was solved in presentproto, which in Ubuntu is in the package x11proto-present-dev. I've noticed that when libxpresent was last compiled, in 2015, Ubuntu still had the version of presentproto without this fix. So I recompiled it on my system and the issue went away - xfwm4 now works perfectly with XPresent. $ lsb_release -rd Description: Ubuntu 18.04.1 LTS Release: 18.04 $ apt-cache policy libxpresent1 libxpresent1: Installed: 1.0.0-2 Candidate: 1.0.0-2 Version table: *** 1.0.0-2 500 500 http://lt.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages 100 /var/lib/dpkg/status ** Affects: libxpresent (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801071 Title: XPresentPixmap() BadWindow, recompiling fixes it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libxpresent/+bug/1801071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
