Control-Alt-Fn Problem - REPOST

[John Austin]

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

Additional Info
I still cannot get the display to work on virtual terms 1 to 6.
I have tried
yum install xorg-x11*

to the latest development version, not to be recommended as
the screen became unreadable at run level 5 and still fails
with Cont-Aft-Fn !!!!

Managed to get it back to the DVD release - just.

Is it time to submit a Bugzilla.

Advice welcome !!!!
