I upgraded recently from 13.04 to 13.10. I have Dell Inspiron 4GB RAM, Intel Core i3. Login takes a lot of time and all the graphics are very slow. Alt + Tab takes a lot of time (seconds).
- After reading some threads, I also removed Cinnamon desktop, but it didn't change anything.
- Tried running in FailSafeX mode, but still the performance is poor.
I had to ultimately fall back to Gnome Flashback (no effects). Gnome flashback works fine without any issues.
Can anyone please help me get back to Unity, else I will have a very hard time running using Gnome.
UPDATE
Here is my /var/log/dmesg and /var/log/Xorg.0.log
I would start by looking at the dmesg and xorg.0.log logs (in /var/log/). I found that the new video drivers required a BIOS upgrade. The logs should give you a clue where to begin. Add them to you question for a better answer.
