I'm suffering the same problem and I've applied the suggested upstream patch in my personal PPA: https://launchpad.net/~tanty/+archive/ubuntu/ppa/+packages
However, I don't think this is a proper fix for the problem I'm observing. When the problem was happening and tons of error is "_xgeWireToEvent: Unknown extension 148, this should never happen" messages were spitted, everything was going much slower in the affected application. With the fix, the application now is mute about this problem but it is still clearly slower. Hence, the error is still happening it is just that we are not seeing the error messages any more. Is this error a regression in libXext ? In my case, I'm specially seeing it in a custom compilation of epiphany, the GNOME Browser, from upstream. It seems to be affecting webkitgtk+ ... I've just upgraded from Trusty and I was not suffering this problem before with the same custom compilation of epiphany. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libxext in Ubuntu. https://bugs.launchpad.net/bugs/1400730 Title: libxext fills up .xsession-errors log files Status in libxext package in Ubuntu: Fix Released Status in libxext source package in Utopic: Confirmed Status in libxext source package in Vivid: Fix Released Bug description: libxext can write debug output, and it can write so much of it that it fills up .xsession-errors t be several GB and fill up the hard disk (or the equivalent file with lightdm). error is "_xgeWireToEvent: Unknown extension 148, this should never happen" [TEST CASE] Install Plasma 5 on utopic Use it for a while Notice that ~/.xsession-errors is filling up saying "_xgeWireToEvent: Unknown extension 148, this should never happen" with the new packages this will not happen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libxext/+bug/1400730/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
