I did the 5.6 update yesterday. When I started the machine today, I did not get a login screen -- it was just a blank screen with no cursor or anything. I shut down, restarted and when grub came up selected the previous kernel. The system came up as usual, presented a login screen, and is working OK. There is apparently something buggy related to the new kernel (2.6.18-238.5.1.el5). Stan Klein --
