I have also been experiencing this problem since moving to Intrepid, but not at first. I noticed it first one or two weeks ago, but it is now a daily occurrence. Alt-Tab does not fix it. Only Ctrl-Alt-Backspace restores the mouse click.
I am running 32-bit Intrepid on a Dell Latitude D820 notebook computer and have only noticed the problem when I am connected to a docking station and using Xinerama. I also see the RANDR error message that Tris pointed out. -- Mouse clicks stop working sporadically https://bugs.launchpad.net/bugs/41301 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
