http://ubuntuforums.org – Back in October I attempted a 12.04->12.10 upgrade. It went almost all well but my X became broken. Now that I execute startx from the console it fails with a segfault (from /var/log/Xorg.0.log): Code: [ 31.985] (II) config/udev: Adding input device ImExPS/2 Logitech Wheel Mouse (/dev/input/mouse0) [ 31.985] (II) No input driver specified, ignoring this device. [ 31.985] (II) This device may have been added with another device file. [ 39.887] (EE) [ 39.887] (EE) Backtrace: [ 39.887] (EE) 0: /usr/bi (Hardware)
