Ah, in your bug report it actually does say Ubuntu not Kubuntu which does change things somewhat.
In order to do anything further I need you to run the following command in terminal which will gather the relevant information about your system. apport-collect 510138 This will gather the relevant critical information and attach itself to this report. As you have also correctly stated, KDE is the GUI for Kubuntu but I'm not sure if this is the correct place to report a bug for that? While i find out, run the above command line as even if this bug has to be passed on they are still going to need that info. -- On laptop Acer Aspire 1810TZ, brightness switch changes brightness twice https://bugs.launchpad.net/bugs/510138 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
