I have the exact same problem. Am using Frugalware 0.6rc1 here. (http://frugalware.org) They have at this very moment GNOME 2.17.91. On same machine warsow and mouse just work in all other WM's and/or DE's. Just NOT in GNOME. In previous version(s) it worked (2.16.x) Also got the same mouse as hangy: "MX510" connected to USB port. Self-compiled metacity without composite feature didn't work either. I don't really know where the problem is or to search for.
ADD: Today starting warsow in GNOME 2.17.91 the mouse worked! About ~30 seconds, then suddenly the cursor stopped to respond and same story as before. ** Attachment added: "my xorg config" http://librarian.launchpad.net/6491259/xorg.conf -- mouse doesn't work in War§ow any more https://launchpad.net/bugs/85766 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
