I have an Acer Aspire computer that contains:

  • Intel Atom CPU 1.33 GHz x 2
  • 2.0 GB RAM
  • Gallium 0.4 on llvmpipe (LLVM 3.4, 128 bits)
  • Disk 243.9 GB

I thought that Ubuntu would run faster than Windows 7, so I installed Ubuntu 14.04. The result was terrible, it runs super slow, even the animation of closing a window runs in slow motion, about 1 FPS. I know its not the best PC, but it stands on the recommended requirements and still works slow as hell.

Any ideas why it is happening, and how to fix it? I thought it was maybe due to power saving mode being on, but I can't find the way to check it.

If you are fine with using a lightweight and so more ugly display manager, try LXDE or XFCE. Maybe even GNOME works better. If it still runs slow with lxde, then something in the system is really slowing... but I have no idea what...

In case you don't know:

Install lxde with minimal adaption:

sudo apt-get install lubuntu-core

...or only the lxde package:

sudo apt-get install lxde

To install xfce:

sudo apt-get install xfce4

And for the pure gnome:

sudo apt-get install gnome-core

Ah, and maybe you want to check first what steals the most power. Open the System Monitor (type it into Unity Dash or run it by alt+F2 or in a terminal with gnome-system-monitor). What is used most? RAM? CPU? Then go to the processes and order them by RAM/CPU usage. Which are on the top?

If you can't find it and my previous answer doesn't work or fit you, I don't know how to help, sorry...

Your problem is the Gallium on llvmpipe part. This means, that instead using the intel driver, your laptop is basically rendering everything on the (very slow) CPU, that's why it crawls so badly. I can't really help with fixing the driver issue, I can only suggest using a desktop environment which does not need 3D acceleration, as @Peter Nerlich has suggested (personally I recommend XFCE, to me, LXDE always felt like an eyesore).

You could share with us the exact CPU you are using, maybe another solution exists for you. I am guessing it uses the Intel GMA 500 (codename Poulsbo) chipset, which has the infamous PowerVR graphics core.

Another possible solution is trying out the older, 12.04 release of Ubuntu. I have a Samsung N150 netbook, with similar hardware, it works without much hassle - though I have only OpenGL 1.4 "thanks" to the pathetic GPU.

I think this must be a drivers issue, as on paper, Ubuntu should be more lightweight than Windows 7. Have you looked for other drivers yet? Go to "Additional drivers" and select a other driver.
