I just installed Ubuntu Studio 18.04.1 and I experience some a massive mouse lag after a while (this question) This happens with 4.15 lowlatency kernel Ubuntu Studio is shippped with. Since I ran out of ideas and wanted to try the generic kernel I installed 4.15.0-20 headers and image. I can boot, but I won't get full resolution on my screen and WiFi device is not available.
How come? Which extra packages do I need to install or remove in order to get this working?
In both of my last OSs Ubuntu 14.04 and Ubuntu Studio 14.04 I had several generic, lowlatency & rt-preempt kernels installed, and switching between them never was an issue.

AMD Radeon HD 6620G graphics adapter (default driver, only LVDS screen used)
Edit I tried all generic kernels up to 4.15.0-32 to no avail..
