I am using a partition created from Wubi, and this is only because Windows is needed for activities like gaming and watching movies on certain websites that require the Silverlight plugin. All of the partitions I have created in the past have worked fine. This new install, however, has a problem.
I formated a month or so back to allow more space. Back then, I only created a partition that allowed for a few gigs of space. I deleted the partition in windows and gave myself the 30gb partition. This is because I planned to work from my Ubuntu partition entirely except for the above-mentioned things. It worked fine for a week or so.
Then, for some reason, the Ubuntu loading screen (the purple one with the four or five red dots that slowly light up) went wrong. Instead of coming to this screen from start-up in my native resolution of 1440x900 and having the dots all light up before the operating system presented the login screen, the system waited a while at the screen with the blinking underscore, then quickly flashed green, presented the purple Ubuntu screen in a low resolution, allowed time for only 2 or 3 dots to light up, and the instantly took me to the login screen.
This was originally only a problem with start-up. However, it is now a problem with shutdown too, and I fear it might be detrimental to my system the way it works. Whenever I shut down, the same purple Ubuntu screen comes up in low resolution. There is no green flash here. It just appears after my programs are assumed to have closed. The dots begin to light up, and after only a couple of the dots light up as opposed to all of them, the system suddenly just shuts down.
Lately, it has also had some other problems. These happen every once in a while as in every three or four days. When I go to shut down, the purple Ubuntu screen will appear but without the dots yet still in a low resolution mode. There will be some text over the logo as if it is a terminal outputting information from the system about closing programs, killing the system, and so on. Sometimes this text appears for a short while before the shutdown.
Other times, my system has actually been stuck on this screen; requiring a hard shutdown. In fact, when I installed Kubuntu Desktop Environment a few weeks back (This was after the problem, so it's not KDE), I shut down my computer and went to bed without confirming it had shut down. When I woke up, my computer had literally sat all night at the Kubuntu logo display screen; having failed to shut down.
Does anyone know what the problem is? I don't think it's my graphics card or processor or anything, even though both of them currently have their problems. Windows loads fine. The Ubuntu partition works fine when I am working in it. There are no problems elsewhere. I do not remember installing any software that would do this. The last big modification to my system around the time this started were simple changes of my desktop wallpaper.
