Bug Description
Binary package hint: gnome-panel
Running Natty alpha with the latest partial upgrades on an HP5101 Mini notebook.
A wireless connection is properly established using driver brcm80211 (I deactivated the proprietary STA/wl driver manually). However as soon as I insert an Ethernet cable and the network connection switches to the Ethernet connection, the mouse cursor freezes. The on-off button doesn't bring up the shutdown menu any longer, but the only way to recover/shut down is to press the on-off button for a longer while.
If I disable the wireless network prior to inserting the Ethernet cable, there is no problem.
If I then remove the cable again and after that enable the wireless network, the switchover also works out well.
This problem didn't exist when running Maverick Meerkat on this same computer. I have done several installs of Natty Alpha after Meerkat, the last being a complete reinstallation with all settings removed from my home directory.
My reason for switching to Natty is that it incorporates a Broadcom wireless driver that works at high speed (130 Mb/s instead of just 2 Mb/s). The speed issue was indeed solved :-)
