I just finished installing BT4 R1 on a Acer travelmate 290 and I noticed that the Kpowersave icon shows wrong battery info. It worked fine in BT4 Final.
Also, the wicd tray icon won't appear automatically like it used to in the previous release. I used the "update-rc.d wicd defaults" command and rebooted. I have to run wicd-client if I want to see that icon. Has anyone else having this issues?
