No signal during boot

[ihinkican]

Hi
I have installed LL2.8 x64 from a live cd to a modest  dell dimension e521 (AMD sempron 3400+). I upgraded the video card to a gforce gt610  at 1360 x 768 and added 3 gig of ram.

My current issue is that when I boot the computer the monitor has no signal until the desktop(xfce) loads. the live cd had a splash screen to cover the usual code that scrolls during boot as did the previous 2.6 and 2.4.

I did not have the issue with 2.6 installed or any  of the live cd versions of 2.4,2.6.2.8

long story short,

In my case the best solution was to go do something else. The system has no signal during boot but once booted the system appears to function. no one has an explaination

second best effort was open /etc/default/grub as root and remove "quiet splash" then sudo update-grub, reboot

If that does not work for you try

hold shift down for the grub menu

hit F4 for a text boot

hit shift F2  to see the boot splash

hit shift F1 to see boot text

remove the # from GRUB_GFXMODE=640x480 in /etc/default/grub ( also try add: GRUB_GFXPAYLOAD_LINUX=text as the next line, ) then sudo update-grub, reboot

try an optional driver

try another distro
