Please use the "xinit" trick from the wiki page in comment 22, which also produces an xrandr.txt file. Copy the new Xorg.0.log like I said in comment 18. Run "dmesg > dmesg.txt". Then use failsafe mode to attach all three files here.
Once the screen is scrambled, you can still switch to a text console with ctrl-alt-F1, right?
