I recently changed my OS to Ubuntu from XP via USB because the cd-drive is not very reliable due to the old age of the PC. but still my system requirements are enough to operate Ubuntu. 1.5 GB of RAM, Intel pentium 4 CPU 2.26 GHz with Nvidia fx 5200.

If you need any more details please ask.

  • The default Unity desktop requires a fairly powerful PC to run at a reasonable speed but you can try installing a lighter desktop such as Gnome Classic or one of the lighter variants as suggested by an answer. Oct 27 '13 at 14:30

I think, that your system configuration is fine to start Ubuntu, but not so fine to use it perfectly.

I recommend you to use more lightweight Ubuntu derivatives - Xubuntu or Lubuntu, that give you better performance on the same system configuration.

  • ok uhh i did install xubuntu but i saw veery minor changes, it's still too slow to use normally. and i tried installing nvidia's driver for my geforve (downloaded a *.run file and installed it using the official method) but after a reboot which was not required i get a blank screen after logging in. now i only see the cursor. how can i fix this?

  • ok i fixed it but still it's slow. Oct 27 '13 at 17:06
  • i take my words back the xubuntu has significantly changed the performance Oct 27 '13 at 17:32

The slowness you encounter is probably linked to the few RAM you have on your PC.

https://help.ubuntu.com/community/Installation/SystemRequirements states that

From experience, we all know that it is recommended to have 2048 MiB RAM to properly run a day to day Ubuntu.

So as already suggested, you should try changing to lightweigth distros. My solution is you add 1Go to your device if possible.
