Hi Leszek, John has zRAM in Raring. It was pulled in by a package he installed, and I try to help him switch it off.
Probably it is better to do it in /etc/init.d, but I am not familiar with that method, so I didn't suggest that method. Please describe it, I'm reading and learning :-) Best regards Nio On 2013-09-29 10:03, Leszek Lesner wrote: > Honestlky I don't get the cronjob. Why is it necessary?
