Re: [dirty hackd]some unnecessary modules loaded at startup

Have you installed e.g. the nouveau video drivers?

Re: [dirty hackd]some unnecessary modules loaded at startup

I guess you will need to look through the logs to see why (or at least when) those modules are getting loaded and then take it from there.

Re: [dirty hackd]some unnecessary modules loaded at startup

just found this in logs, nothing else

... kernel: usbcore: registered new interface driver btusb

so i dirty hack'd it by adding

blacklist nouveau
blacklist mxm_wmi
blacklist wmi
blacklist ttm
