i have the fix for this issue, i will make a bug report for it for
people to find it easier.
THE FIX:
if you are getting a blank screen or you're monitor turns off instead of the
bootup splash, the fix is to download a kernel from kernel.org or "sudo apt-get
install linux-source" and configure it with "make menuconfig" go to device
drivers, graphics , and you have an option to enable VESA (it's under VGA 16
something). then compile you're kernel using make-kpkg which you can get by
"sudo apt-get install kernel-package. so after making menuconfig, and have
configured the kernel , in the top source directory do this after installing
kernel-package:
"make-kpkg --rootcmd fakeroot --initrd --append-to-version=-some-string-
here kernel-image kernel-headers"
replace -some-string-here with anything you like, like my-custom-kernel. that
command should compile you're kernel and create a .deb pkg for the kernel and
for the headers. then go to /usr/src (if that is the directory where you
extract you're kernel) and you will have the 2 .deb packages. install them. the
installer should install you the new kernel and the new kernel headers. it will
also configure you're bootloader.
REBOOT and see how it goes. you should get a splashscreen now, if no splash
screen make "vga=792" to the bootloader's kernel line. if it works, you can
remove kubuntu's default kernel from adept/synaptics and keep the kernel you
compiled.
(this was somehow stupid from the developers to disable the vesafb by default,
because kubuntu-desktop/ubuntu-desktop by default gives you the boot-up splash,
and boot-up splash doesn't work without vesafb)
