My hardware:

Dell Latitude D600 laptop
Processor: Intel Pentium (r) 1.8 GHz
Memory 1.2 GiB
Graphics R200 (RV250 4C66) x86/MMX/SSE2 TCL DRI2
Disk: 37.7 gb

I did an update from 11.?? using the automatic system update that pops up when you switch/log on.

Ever since then when I switch on the machine it takes approximately one hour to get to the login screen.

Sometimes the actual login will take time too, but sometimes within a couple of minutes I am logged in.

Once I am logged in I find I can work normally, the response is not swift, but is neither too slow that I cannot work.

I was wondering if there was anything I could do to speed things up.

I deliberately did not do a clean install from disk, because I did not want to loose settings on the machine.
