I upgraded some old systems before from fedora 4 and fedora 6 to fedora 9 and 10 using the cds, When I booted the cds of fedora 9 and 10 it detected the old installed fedora and offered to upgrade it, It sounds nice, I chose to upgrade and every thing went fine, The old fedora 4 and 6 became 9 and 10.
I have a problem using Gnome on Fedora 17 where, after a period of time, I cannot regain focus on any windows; that is, I can only see the desktop screen. If I Alt-Tab I can see the other windows, but if I try to switch to them it immediately goes back to desktop.
I have spent over 30 years researching and designing networks - from the time before there was an internet, or tcp/ip, or even ethernet - so I'm not exactly a noob with regards to networking. But this problem has me stumped.
I just did an upgrade to Fedora 20 so I can check out the "new" Gnome 3.10 desktop. Upon boot my Grub still gives me the option of booting to Fedora 19. How can I remove it so I'll just have Fedora 20 installed? I've done the "clean all" to get rid of stuff that's not needed but I'd like to just have 20 on my system to free up some hard drive space.
