Hi I have a Sony Vaio Z VPCZ1290s with Intel HD graphics 1920x1080 resolution. Im having the same problem with it when installing BT5 Gnome64bit. The only way I could get into the terminal is with the nomodeset parameter but when I startx the screen goes black and the caplock LED start flashing. I tried the i915.modeset=1, i915.modeset=0, changing the vga=1 to 2 in the grub menu but the screen would still go black after a few moments. Does anyone have other solutions?
