Tumbleweed black screen after welcome screen ..

Hi,
Please notice that i already installed old opensuse 11.3 on this old machine a few years ago …
I boot on install dvd and i see the welcome screen !
F2 → language and keyboard → france
i select “installation” … enter …
then kernel loads and text scrolls on the screen … until “opensuse tumbleweed installation”
then black screen … and nothing
no more gui screen…
Can anybody help me ?
Thanks

How old? How much memory? What video card?

Did you check the download, check the install media?

I checked the media (sha256) and i have the same problem with boot on usb stick…
Hardware (2010) : cpu intel core i5 750, 4Go ram ddr3, video ati radeon hd5850…

Somebody solves the problem on another forum!

Before clicking installation :
F3 -> text console size -> no kms

Then installation goes on !
