Hi All I have just installed FC4T1 x86-64 on Ext USB disk Only problem being installing a boot loader, don't trust it! The options don't seem correct. I selected Do not install boot loader!!! I then did a mkinitrd and grub setup by hand to USB disk after install complete. Clean boot from USB without touching MBR of main disk. Usual gdm problem but as I use kdm ... Need to edit /etc/X11/xdm/kdmrc to permit root login !!!! 2nd occurrence of AllowRootLogin for anybody interested. However Cont-Alt-Fn to switch to a dumb virtual terminal causes the graphics to fail. The screen/keyboard is active and you can log in blind, mingetty running OK, but not very useful with nothing to see. Suspect that the graphics resolution/scan rates not supported by LCD monitor but not certain. Seems odd as... The main disk of the machine runs FC3 x86-64 with no such problems Graphics card is very standard Matrox G550 Monitor Iiyama AS4314UT Has anyone seen this problem or know where the default settings are for the virtual terminals? Thanks John
