Yes, downgrading all libraries for the whole systems causes lots of problems, including with some gnome applications and programs that use OpenGL. We have developed a better workaround, that modifies the environment of the `kwin' binary only. The rest of the programs run unaffected with the default libraries as provided by Ubuntu.
I'm attaching the wrapper script for kwin that we are using (read the comments at the top of the script). I'm also going to attach the output of "ls -lR" for the directory where the downgraded libraries are kept. ** Attachment added: "kwin warapper - read the comments" https://bugs.launchpad.net/ubuntu/+source/libx11/+bug/985202/+attachment/3419973/+files/kwin -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libx11 in Ubuntu. https://bugs.launchpad.net/bugs/985202 Title: libx11 causes kwin to crash on login (over NX protocol) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libx11/+bug/985202/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
