[Bug 1448431] Re: xhost access control fails to add other users
I have used this functionality extensively, and wrote a few scripts to make it easier to run programs as other users. So I ran into this rather quickly on 15.04. As a workaround, you can use xauth instead. For example, as a script: #!/bin/sh OTHER_USER=user2 echo Giving $OTHER_USER xauth key XAUTH_KEY=$(xauth list | grep $(uname -n) | sed -n '1,1p' | cut -d ' ' -f 5) #If XAUTHORITY is set, it probably won't be a file writable by the other user unset XAUTHORITY sudo -Hu $OTHER_USER xauth add $DISPLAY . $XAUTH_KEY sudo -Hu $OTHER_USER xclock echo Taking $OTHER_USER xauth key sudo -Hu $OTHER_USER xauth remove $DISPLAY -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448431 Title: xhost access control fails to add other users To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/x11-xserver-utils/+bug/1448431/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
