Hi tux-sven, yes, that was fixed :)
I'm rejecting the ISO again though... we're having last minute additions (exfat support, thermald etc..).
It was much easier to connect to the bluetooth mouse with this reease than Mint 17.3
Now for the first time I succeded starting up LM18 Mate 32/bit (installation stick) correctlly on my littlle Acer Aspire One!!!
I will continue testing later today...
