As I read the personal opinions and reviews of other Ubuntu users, I see that people are not satisfied as expected. Some old drivers are not working, some new problems start from out of nowhere, and improvements can not cover it all.
First of all, I’ve got an NTFS disk and I store my all my music, video and any other files on that disk. Whatever I did; expect one thing that I’ll soon write down, Ubuntu hasn’t mounted that disk at start. The simplest example, my wallpapers are on that disk, too. And everytime I start Ubuntu I see an orange colour screen until I open Computer and double click disk icon.
Solution is; first check tow packages if installed on your system (one comes installed as default actually); ntfs-3g and ntfs-config, than you need the program pySDM (which SDM stands for Storage Device Manager). After installing that program you need to select your disk from its interface and and click assistance.

After that you must select the checkboxes like this:

I mentioned about problems, for example one thing I like very much in Ubuntu is screenlets. My screenlets just doesn’t run. Some people get some error messages like mine. But I couldn’t figure it out to start them. I re-installed (removed the configuration files also) it but it doesn’t work. It was just working on 8.10? What happened since then.
I insalled Gnome-do a few days ago. I don’t want it to start on boot, but it does. First I changed its settings to not to leoaad on startup. It still does. Then I opened “Startup Applications”, called “Başlangıç Uygulamaları” in Turkish. And unchecked it, nop. It didn’t work. So I removed it from my system.
Firefox does not upgrade to 3.5 from 3.0.* version. Do not be surprised. You must install Shiretoko (which is I suppose codename for Firefox 3.5) then you can use your upgraded Firef.. Oops Shiretoko.
And at first times of Jaunty; one of my most loved apps, UbuDSL was not working. Because something changed in Ubuntu, it needed an upgrade from developer and then worked. It works like a charm now. Better then Windows or Pardus (does not have an interface but OK) version of similar programs.
Yesterday I selected and added nearly 100 wallpapers and when I reboot they were not on the wallpaper list. Something is going on with the Jackalope but I do not understand that.
If something just does not work like the previous version, I personally do not feel so into that version because of just trying to solve the problems.
