I can confirm this problem from a clean install of Kubuntu Feisty Beta, updated to 20070325. Everything is like the first post says. This is a x86_64 install on a Gigabyte mobo with an on-board nVIDIA 6100 GPU, part of the nForce 430 chipset. I have yet to check if this same problem happens running the propietary nVIDIA drivers, but as they have another set of currently severe and unfixed issues I have been unable to carry those tests.
As the one eway to fix the cursor problem seems to reboot the box, it seems like a problem with the driver setting some register on the board on boot, and unsetting it under some circumstances and never resetting it back to normal. Maybe an issue with the hardware cursor? Maybe forcing the software cursor could workaround this problem in the meanwhile. Hope it helps. -- mouse cursor disappears https://launchpad.net/bugs/63905 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
