Thanks for the incredibly fast answer to my previous question! I will go with an other one:
I did: su - dpkg-reconfigure x11-common dpkg-reconfigure xserver-xorg-legacy choosed to allow all to start xserver then, I tried first as a normal user, then as root (because you said root was allowed to lspci devices, not normal users): startx results in: xinit: unable to connect to X server: connection refused grep EE /var/log/Xorg.0.log show that: failed to load fbdevhw (invalid module, 0) VESA(0) Cannot read int vect Was it expected?
