I have a weird problem with fedora. It just suddenly stopped working.
Yesterday, I turned it off just the same way as other days and I can't remember installing any new packages, but today it won't boot up - it didn't get to the part "starting display manager" and fedora logo didnt get filled. So the first thing I tried was booting with older kernel, which didn't work so I choosed the oldest one and it loaded (a bit slowly, it sometimes happen randomly) so I did software update "sudo yum update". It installed new kernel and other packages (some network manager, libreoffice...), there was some problem with virtualbox and its dependences, so I skiped it. The new kernel didn't work, and the one which worked also stopped working. But this time it is differend. The fedora logo got filed, but it automatically jumpes into the log. There is everything allright, it got past the "starting display manager" and ended at starting sendmail or something like that. Everything runs with "OK" status.
I can get to command prompt - I tried reinstalling kernel, gnome-shell, bash, gdm, gtk3 just in case if they were broken, but it didnt help. I also removed the virtualbox (which had broken dependences) and other akmods, but it didnt help.
I don't use ATI graphics drivers, bc they doesn't work.
I can succesfully boot into my second "emergency" distro (ubuntu), so there must be something wrong with fedora...
