okey, then something has gone wrong in the installation because i get a console flashing by complaining about mounting just before the installation menu pops up when i boot from the cd.
so i still dont think it has to do with the grafics card (but i could be wrong)

This is normal for the Lubuntu installer . It also happens with the Sam440ep installer.
It does not affect the installation .
So what you need to do Is run the installation with the Radeon HD4650.
Delete the Linux partitions created by the previous installation and leave the un partitioned space before booting the Linux installer .
Do the base install and reboot and boot into LInux. do not change anything.
If you do not get any display on your monitor then something may be wrong
with your hardware.

okey i will try and install with the hd4650 card.

so now i have tried installing with the hd4650 card and it was a success
seems you where right that it was the hd7750 card that was failing to show the console.
unfortunatly i was also right that something more is wrong with my hardware i have successfully installed xinit and fluxbox with firefox browser now but not without some headache.
it seems its some kind of information coruption happening when installing software so you have to try and fail a couple of times before it is installed :/
but atleast i have manage to install linux now so maby i can install some diagnostics tool so i can see whats wrong with my sam460

Ram and hard drive are two possible problem areas.

yes ram was my first thougt when i first got it so i sent it back and got a replacement ram so that possibillity was ruled out.
will try with a couple of different hard drives now to se if the problem remains.

@Spectre660

I am experiencing random crash using kernel 3.16.2, both on Lubuntu 14.04 and 14.10.
After between 10 to 20 minutes of normal usage (mostly plain x-terminal stuff) the system simply hang without any error message neither on the screen nor via the serial port.
The system freeze, the screen doesn't present artifacts, any process stop working, and the keyboard and mouse stop working.
Does somebody experienced these on Sam460?

What graphics card are you using ?
It may be the radeon dpm.
Try adding radeon.dpm=0 to your menu.lst command line to disable it.

That's a pity. I think ACube has forgotten you because of the Sam460 Lite.
