14.04 or 16.04 on Lenovo x260

[vladkatz]

Hi,

I got a Lenovo X260 from work and I need a stable native linux environment. It appears X260 is in the ubuntu 14.04 compatible list, but not yet in the 16.04.

I installed 16.04.1 yesterday and I get occasional errors - app store is running impossibly slow, cpu usage tends to rise for a single core while others are practically idle, when I first run chrome it gave me some errors, etc. In general, though I mostly work with the terminal, it's not a very "smooth" user experience.

Our IT team won't help and I need an advice:
Should I reinstall the system with 14.04?
Would you perhaps change to diffenent linux distribution? Or plainly keep 16.04 and work around the errors?

Thanks!

What are the specs of that machine; it could be one of several versions and that might affect which version we suggest; if it has an AMD graphic card (unlikely, I think, but would be useful to know) 14.04.1 could be the best version to use so you can still use the fglrx proprietary driver.

Did you install 32 or 64 bit? Ubuntu, Xubuntu, ??. Welly need the specs on that machine like ajgreeny said.

Graphics card is an Intel on-board 520, so that's not an AMD issue. I installed the 64bit. Here are my specs:

With that new of a processor better to stay with newer Ubuntu.

Did you install the Intel driver update?

Updates often needed for Skylake or Kabylake

I have a Skylake system, and after update, it gives me warnings that the Kabylake version may be required. I ignore warning as it seems to not know system is just Skylake.
