I finally upgraded to Ubuntu 9.04 last weekend. My wireless card quit working. I tried several things like reinstalling the broadcom driver and all, but it wouldn’t work in Ubuntu 8.10. I thought “”what would it hurt”, I will probably have to reinstall anyway.
The upgrade went with no problems, but it still didn’t fix my wireless problem. I finally determined that my problem was with the network-manager and not my driver because I could see it with ifconfig. So, I completely removed the network-manager, rebooted, and reinstalled. Still no luck. So, I was sitting on the couch programming with no Internet, and it just started working again!
I have noticed a few things working better! First, when I do my dual screens, I noticed that it now places my Applications bar on the laptop screen. Before, it didn’t seem to matter how I switched to dual screens, it would place my Applications bar on the other monitor.
