Ubuntu running slow on my good machine!

Question

Its fixed now :)

I just installed Ubuntu on my PC. I lag a lot. My pc runs all other OS' at high speed, but ubuntu lags like hell. It worked on my old laptop.

My Specs:

XFX AMD Radeon HD 7870 Black Edition
AMD A8-3800 APU
2x4 GB 1333 MHz Ram
1TB Harddrive

I installed the latest version of Ubuntu. 13.04 I believe.

I run Windows and other linux distros really fast, so why does Ubuntu lag?

Can you edit your question to include what version of Ubuntu you are running? — jobukkit, May 05 '13 at 08:22
There is no 13.0.4. Maybe 13.04. Check in a terminal with this command: lsb_release -a to be sure. — Radu Rădeanu, May 05 '13 at 08:46

First, make sure you have the drivers needed, so open a terminal, and run this:

sudo apt-get purge fglrx*
sudo apt-get install fglrx
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
sudo aticonfig --initial

Then reboot.

If ubuntu is still slow, you might want to change your desktop environment to something like LXDE, XFCE, KDE, or GNOME (though GNOME under ubuntu can be slower than unity, partly due to the excessive patching made by canonical).

Ubuntu runs faster now, but in the left lower corner it says Unsupported hardware. – Jonas Rothmann Hjalager May 05 '13 at 09:17
