Uh? I have a Pentium T4400 and it should have two cores with two threads each, so a total of 4 logical cores. It should then run 3 processes but actually I get 6 :-? >> https://www.enlightenment.org/ss/display.php?image=e-57b9a7baf33cd3.64891532.jpg >> >> Am finding here, OpenBSD, that I'm not having thumbnails generate >> anything...regardless of the above just have black windows when moving >> through the video rather than preview. > > i am not sure why. generic loader not working? something else? no info here to > go by. > >> On Sun, Aug 21, 2016 at 2:05 PM, Carsten Haitzler <[email protected]> >> wrote: >> >>> On Sun, 21 Aug 2016 14:22:33 +0200 Massimo Maiurana <[email protected]> >>> said: >>> >>>> Carsten Haitzler (The Rasterman) ha scritto il 21/08/2016 alle 14:03: >>>>> On Sun, 21 Aug 2016 10:42:47 +0200 Massimo Maiurana < >>> [email protected]> >>>>> said: >>>>> >>>>>> Carsten Haitzler (The Rasterman) ha scritto il 21/08/2016 alle 01:42: >>>>>>> On Sat, 20 Aug 2016 19:04:44 +0200 Massimo Maiurana < >>> [email protected]> >>>>>>> said: >>>>>>> >>>>>>>> Carsten Haitzler (The Rasterman) ha scritto il 20/08/2016 alle >>> 14:17: >>>>>>>>> On Sat, 20 Aug 2016 09:41:00 +0200 Massimo Maiurana < >>> [email protected]> >>>>>>>>> said: >>>>>>>>> >>>>>>>>>> There is an annoying issue that I found in rage from some months >>> ago >>>>>>>>>> but I've always forgot to report it here, sorry :( >>>>>>>>>> >>>>>>>>>> There are cases where rage_thumb just go crazy, spawns several >>>>>>>>>> processes, eats up the cpu and reamins active even if I close >>> rage, so >>>>>>>>>> I have to "killal -9 rage_thumb".
