It looks like the bug's been fixed in one of the latest updates. The screenruler package version is unchanged, but several packages where updated since I first reported the bug. For example uname -a now reports:
Linux <computername> 3.2.0-49-generic #75-Ubuntu SMP Tue Jun 18 17:39:32 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux On my part this bug can be considered fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169469 Title: ruler invisible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/screenruler/+bug/1169469/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
