Well it looks like this may be a duplicate of a much older bug, but I can't for the life of me figure out how to link the two. It's bug 74069.
As to the comments in that bug: I can confirm that going to a terminal and typing "sudo shutdown -h now" works. When you turn the computer back on the mouse will work properly (as contrasted to "sudo shutdown -hP now", which makes it not work). I can also confirm that a firmware update on the mouse seems to have corrected the shutdown problem. I can now use the Shutdown choice on the Gnome menu to shut down the computer and the mouse still works when it comes back up. However, I do note that both dmesg and Xorg are still recognizing my mouse as both a keyboard and a mouse. I also noted that it seems to be picking up something as a "Macintosh mouse" (always was, by the looks of it, I just didn't notice). I guess it's worth noting that the only USB devices I have connected to the computer are the Razer Copperhead and the G15 keyboard. I have no PS/2 devices connected. No clue where this Macintosh thing is coming from. Also, I forgot to note originally that I'm running the 64-bit kernel. -- mouse detected as keyboard https://bugs.launchpad.net/bugs/327037 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
