What does the file /etc/X11/xorg.conf say for the option Emulate3Buttons? To find out quickly, at a terminal enter:
grep Emulate3Buttons /etc/X11/xorg.conf If it does not say “true” (or “1”, “on” or “yes”), you could try changing this setting by at a terminal entering: sudo dpkg-reconfigure xserver-xorg Accept the current answers until you reach the “Emulate 3 button mouse?” question. This is not a user-level option, which is presumably what you are looking for, so I shall leave the status of this report alone for now. -- KDE No middle mouse button simulation with two button mouse https://bugs.launchpad.net/bugs/250358 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
