Im a first-time user to Ubuntu-12.04 with WUBI installation.
I have a Dell vostro 3450 with i5 2410m, 3 gb ram, intel hd3000, amd 6630m hybrid.
Surfing and playing games works flawlessly. However, I'm having huge problems when installing applications and generally copying and moving files.
When doing so, system is significantly slower and freezes quite often (Firefox gets bluish, sometimes even black n white). I would say that Ubuntu allocates too much resources on file transfers and installing, but even these tasks are very slow.
Here is very specific example : Today I tried to move a 6 GB file from my Windows 7 installation. It was good at first, so I jumped to Firefox but after a while firefox started to randomly turn bluish and mouse was randomly stopping working. It was gradually worse and worse until it got to a point when firefox black and whited and mouse wasn't working at all. I raged and went for some meal, when I got back screen was black. It probably unlogged me due to inactivity, when I pushed random button to bring screen to life I had to wait few minutes to let it show me only my screen background. No log in screen, just background and working mouse. NoteBook fan was working at 100 % so I assumed that file transfer was going on and I left it to work. Nothing then changed for a full hour so I hard rebooted it. File transfer unsuccessful, It transfered hardly 2 gigs. Is this normal ?
What to do in these situations ? It didn't let me load system manager and not even the terminal.
