Problem starting gdm resolved by vga kernel parameter
L.S.
You are probably not the right group to write to, but you are likely to
know where to forward this message.
The problem I had/have is that during boot while starting gdm my LCD
monitor (CTX PV700) complained with "Signal Out Of Range", "H:36.8 kHz
V:82.2 Hz", "Mode Should Be Below", "1280 x 1024 / 75 Hz". This message
shows for approximately 4 seconds, and then the X-server seems to work
normally.
After a morning of googling and experimenting with several settings
in /etc/X11/xorg.conf (I even copied a Knoppix version in, which did not
have this problem in Knoppix) I gave up because nothing seemed to have
any influence on the problem.
Then this afternoon I started googling to find out how to change the
fontsize in my tty's. After adding a vga parameter to the kernel in grub
my "Signal Out Of Range" problem disapeared. As far as my experiments go
it does not seem to matter what value the vga parameter has.
This finding is consistent with Knoppix and openSuSE not having this
problem, because both these distributions change to a smaller console
font.
Below I will add some additional information on the versions I am
running. I will be happy do give additional info if needed, and I can.
Kind regards
Hans
