i enter with kernel 4.3.0 RC1 again because with version 2 of kernel i have blank screen
i send you the Xorg.0.log
p.s.

i try to install debian 8 with second version of kernel and same error...blank screen before linux load

Thank you for the Xorg.0.log file. The problem is, that the Radeon driver doesn't detect any Radeon HD graphics cards.

Error message:

Christian the same error with Lubuntu

This is very sad.

lspci | grep -i vga looks directly on the PCIe/PCI bus.

Please post lspci without vga.

Additionally post the output of the following command:

Code: Select all

sudo lshw | grep -i vga

FYI: [kind of Solved] AMD Radeon HD 7950 support ?

FYI2:

For HD7950/7970 Use TAHITI

The varsion of Xorg drivers supplied with current distributions (6.14) doesn't recognise these cards causing the xserver to fall back to the fbdev driver. This has a maximum resolution of 768 x 1024, so I've compiled 7.1 which will work better.

Is the package xserver-xorg-video-ati installed?

If not then you can install it with:

Code: Select all

sudo apt-get install xserver-xorg-video-ati
