I'd focus on profiling the X server, making sure the profiles show symbols, ideally with call graphs. sysprof or perf might work better for this than oprofile.
Thanks. Lucky me, that this is not needed now and I can postpone how to figure out how to start X that way under Debian with GDM.
For future reference, sysprof and perf can be used to perform system wide profiling - that is you can launch them after starting the task you need to profile. For sysprof this is its default mode, and for perf you need 'perf record -a'
A quick 'sudo perf top' is always a useful first step. For best results, make sure you have debugging symbols and frame pointers. -Chris
