Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I always wanted to use Ubuntu as my main operating system - mainly because of unity. Unfortunately i can't. Whenever i install Ubuntu on my pc, Ubuntu is running as slow as my grandma.

I have tried different versions of Ubuntu (14.04, 12.04), Wubi and running in Virtualbox (From Windows 7).

They where all extremely slow, way slower than Windows. I then tried Elementary OS, which should be faster. And it was - it was running like a dream, almost instant boot, fast program startup, etc.

Now i'm using Pinguy OS, which is running fine also. I just have no idea why Ubuntu doesn't work - because distros based on Ubuntu apprently are working fine. (Arch linux is running fine also)

Could this be because my hardware (listed below) doesn't work with unity, or...? Just hoping someone can explain this, not necessarily a solution.


CPU: Intel i5 3570 (Non k version)

GPU: Asus GTX 670

Motherboard: Asus P8B75-M

RAM: 8gb Kingston

Nothing has ever been overclocked or anything, and it's running fine in windows...


Why does Ubuntu run slow, when Ubuntu based distros, Arch Linux and Windows run normally? Unity incompatible hardware?

Did you try to install the "Additional Driver" for your Nvidia gpu? – TuKsn May 19 '14 at 12:55
Yes i did ;) Also my CPU usage were extremely high. 80% viewing YT videoes, 60% moving a window around... – Frederik H. Petersen May 19 '14 at 13:03
Is your BIOS version up to date? Check cat /sys/class/dmi/id/bios_version – TuKsn May 19 '14 at 13:11
Perhaps... Which version of Nvidia driver did you try? Did you get more than one version for selection? – TuKsn May 19 '14 at 13:25
You should also try the other versions. – TuKsn May 19 '14 at 13:28

First of all, how slow is slow?

That said, stock Ubuntu is heavier on the GPU than many Ubuntu-based distros because of Unity.

Furthermore, Ubuntu (or basically all Linux distros) is known to have issues with NVIDIA GPUs. You are running an NVIDIA card. It's probably wise to install nvidia drivers.

EDIT: Running anything virtualized will be slower than full install. Wubi is no longer available for newer versions of Ubuntu. To test the full speed of Ubuntu, you should really do a full install.

I tried both full install of 12.04 and 14.04. I also tried running Wubi and Ubuntu i Virtualbox – Frederik H. Petersen May 19 '14 at 13:04
