I recently updated from 17.10 to 18.04.
After the upgrade I've noticed that desktop applications constantly, randomly lock up. This happens about once every minute. The constant random freezes last from about 1 second to 20 seconds.
This issue makes my computer unusable as a work desktop.
I've got a relatively powerful computer: it has an i7 and 16Gb of RAM. So the issue can't be from lack of resources.
lspci | grep VGA
Returns VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)
I understand that this is a relatively good video processor, so I don't expect issues there either.
What could be causing the freezes? How do I prevent them?
I had same behavior as described here (fresh installation of Ubuntu 18.04 on a new computer). I feared some hardware issue between the cpu (AMD Threadripper), the mainboard (ASUS x399) and the video driver (tried with Nvidia GTX 250, GTX 550Ti and GTX 750 Ti, nothing changed).
Then, today I updated Chrome to the last stable version, 68.0. All freezes and hangups are now gone. Hope this can help someone.
