Hi,

A lot of people have said in previous topics about dumping the graphics cards BIOS from terminal.

 

Have you tried dumping the BIOS of the graphics card to a file and then ensuring the VM tries using this ROM for output?

 

See the below video link on dumping bios using putty or any ither SSH tool.

 

Note: Failing the below, you could VBIOS dump using GPU-Z.

 

 

This seems to be quite a common problem.

yes i did. and by doing some other test i finally found out..... I thought i tried the Q35 machine setup but it seems that it never worked before..... and it was the problem so switching it to Q35 and changing manually the xml finally did the work shit im so glad now!!!!

Thx for the help
