I have had some odd problems with my Ubuntu lately: The mouse goes on and off and every once in awhile. Also while I’m working with GIMP it randomly disappears!(Goodbye unsaved work) I had problems with sound after about 5 months with the last version. It annoys me but I figure since I do a fresh install every 6 months (right after the latest version comes out)I can live with it. Right now I’m on a very old machine so I’m using Puppy Linux.
Nary a burp from mine (knock on wood) ! I don’t have puppy linux yet so will snag a copy for some really old machines gathering dust on the shop shelf and see what they will do performance wise........
Hope ya get that bug figured out !
