So I just installed Ubuntu 13.04 32bit (alongside windows 7), everything fine in the installation, I loged in and everything fine, until I opened the dash home, it was absurdly slow, so slow that the computer froze and i hat to restart it. So I looked for a solution on internet and I installed "unity tweak tool" and disabled blur on the dash home. That helped A LOT, but it's still quite slow (mostly while typing, but everything in general is slow) but at least it doesn't freeze anymore (at least not everytime I open it, since i did that blur thing it just froze once) but as I said, it's still quite slow and this is very annoying, is there a solution? here is my computer info if it helps:
RAM: 2GB Processor: AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ × 2 Graphics (drivers): Gallium 0.4 on NV46
