When you set "Modes", you are basically saying you want to use certain
modelines (the driver usually has a bunch of standard ones already
defined - like 640x480). You can define custom modelines in the
Monitor section and that, essentially, is what you are doing.
So, you've defined a mode called "1360x768_60.00" in the Monitor
section, and you're trying to invoke a mode called "1360x768 at 60" in
the Screen section. You need to match up these references.
While we're at it - I'm not 100% about the PreferredMode in the
Monitor section, but I imagine those names need to line up as well.
So, pick a name, and go with it consistently in your xorg.conf.
Cheers.
