After installing ubuntu 18.04 I have now a noisy background when being on the login screen, there is not a nice image anymore and the login experience feels a little screwed up (tap on touchpad doesn't work either for example).
It could be worth mentioning that I have installed / root on a 25gb SSD to have a faster file transfer/boot up time and installed the /home in the HDD.
Any Ideas of what could be happening?
