Hi folks, FedoraCore3 After an accident it took prolonged time to start Init 5 (X-window-KDE desktop) - starting GUI login screen :- about 15 min - starting KDE desktop : another 8 min After KDE deskop started, it can't work there. Clicking/selecting the Menu with mouse pointer has no response. After GUI loging screen started, from there selecting; Shutdown --> Shutdown The screen just hung with a pink bar appeared at the bottom. PC was still turn-on. What I can recognised at the begining of booting was following line displayed on screen; ..... Setting default font (latercyrhab-sun16) [OK] ..... If IIRC, there will be trouble on booting Init-5, KDE desktop, should the above line appeared. There is no problem booting Init 3 on turn-on the PC and from there to start X-window, Gnome. (I haven't tested KDE desktop there. I forgot "Kstart"/"startk" ?) The accident was caused while playing around installing "Grub" bootloader on USB pendrive plugged in an USB port on a USB 2.0 PCI Controller. After changing drive; # cd /mnt/sda1 # grub find myusb (hd0,0) # setup (hd0,0) (I left out "root (hd0,0)" before "setup (hd0,0) ) the screen then hung. I have to press a hard-reboot. Please advise how to fix this problem. To umount /dev/hda2 (FC3 OS) after booting up Init 3 whether to run "umount /dev/hda2" then to run "fsck /dev/hda2" ? TIA B.R. satimis
