I just bought an acer aspire E5-521-62DW - NX.MPQEB.001
It has 12Gb ram, 1 TB hdd, AMD A6-6310 processor (4 kernels, 4 threads), AMD Radeon R4 graphics.
It takes more than 1 and a half minute to start, and every application starts really slow. Chromium for example, when I type some text it takes around two seconds to appear. And the touchpad is'nt working...
Do you know if maybe my new laptop is not compatible with ubuntu 14.04 or what could be happening?
