Your kernel log in comment #2 is showing a lot of crashes in the nouveau kernel driver. The best and only remedies for that are:
(a) Install a newer kernel or just install a newer version of Ubuntu. Ubuntu 19.04: http://releases.ubuntu.com/19.04/ or kernel packages: https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D or (b) Continue trying to get the Nvidia proprietary driver working, per bug 1830000. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1830029 Title: nouveau driver for nvidia is sluggish on GTX970M to the point of unusability Status in linux package in Ubuntu: Incomplete Bug description: I am trying to use the nouveau drivers on a recent (today) install of 18.04 on a 2.5yo laptop. Unfortunately the nvidia drivers don't work at all. What I am finding is that the sluggishness of the display is comparable to the case when nouveau drivers are disabled. The only real difference is in the amount of noise coming from the fan because of a slightly reduced CPU load due to Xorg. I don't even know where to start looking into this intelligently, but I would have expected that the drivers would have gotten to a usable state in the past 2 1/2 years since I last tried them on this machine.
