I upgraded to Kubuntu 10.4 Lucid

I had problems with

1. wireless network - see lspci, dmesg, /var/log/syslog; I uninstalled network-manager and installed wicd. It helped. I can have at university my wireless network. but still I don't have at home.
2. I have problems with my big Dell 2407WFPb screen at school on the newest kernel 2.32-21. I have to use 2.31.
