Hi, We have a fc1 linux with kernel 2.4.22-1.2188 and 2.4.22-1.2194 installed. The X-window was working well with kernel 2.4.22-1.2188. This morning, I ran up2date to get kernel 2.4.22-1.2194, installation went through without error. However, after reboot, the X-window cannot start. The monitor shows the text-mode login screen, then a sound of clicking, then black, then the text-mode login screen, then a sound of clicking, ... endless. I restart the system and select kernel 2.4.22-1.2188, X-window cannot start either now, the same as above. It seems that the monitor has been damaged by kernel 2.4.22-1.2194. I could test another monitor on it, but before doing that, I want to know how to set the system starting with a pure text mode, then I can probe a new monitor to prevent it from burned. Thanks a lot!
