Feisty had started to cause me some problems. It started hanging, I could not trace the problem to a particular program so i think it was the kernel. My computer used to hang. Although the mouse still worked, I could not kill X with Ctrl+Alt+Bksp. So I could not wait for a few days for the final release I installed Gusty RC. A lot of people are having problems with this new version. For me there is good and there is bad.
At first I noticed the program called Cheese, I had given up finding a program like this a few weeks back. Although I had the camera driver installed it was not of much use as there was no such program that worked for v4l2, except for a few video chat apps. Another thing good about gusty is power management for laptops. Feisty usually lasted for a little less time compared to vista, but now in gusty I can run my laptop for much longer than vista. Btw I accidentally deleted few of the boot file for this MS OS, I cant recover it unless I format my whole computer using the recovery disk that came with it. Well maybe I’ll do something about it in a few months when I want to play Age of Empires or Counterstrike. Lastly compiz-fusion makes my computer somewhat cooler than what Beryl made it. Virtualbox makes visualization extremely easy and fast.
Then the bad side. Somehow Wifi connectivity on feisty was amazing, it connected when vista could not connect to a wireless network(which btw should connect as it came preinstalled with my computer) . On gusty I am encountering problems with wireless sometimes(similar to vista), although it works totally fine at home. Suspend stopped working! Hibernate doesnt work too but it didnt work with feisty either. Even after reading all those posts in the forums I could not find a work around.
Some general problems related to Linux. No easy way of configuring s-video output, somehow the nvidia control panel does not detect my connected TV. Card reader drivers dont work with MMC. Suspend/hibernate problems. Otherwise everything works pretty good. I dont like Ubuntu’s default brown theme.
