The installation went fine until kde desktop tried to start. The system froze with the following message: The current input timing is not supported by the monitor display. Pleas change your input timing to 1920x1200@60Hz or any other monitor listed timing as per the monitor specifications.Is the login/password window showing up ? Does this message show before or after logging in ?I'm using a Dell U2412M monitor on an AMD 64 4 core system. The monitor worked fine before and still works fine on another computer. I tried both xrandr and compiz in Recovery Mode. In both cases I got "Can't open display".In recovery mode, xorg is not running so xrandr has no X server to connect to. HTH
The sequence of events on boot up are Bios screen, Debian Window with OS selection, Boot up sequence, login/password ( Xorg not running), startx -> error window. So to answer your question, the message is after login/password.
I hope this gives you some incite to my problem. I tried the other suggestions with no results.
Question: Where is the file that contains the display setup (ie refresh rate, resolution.) Where would randr get its information if Xorg was running?
I would have responded sooner but have been hit with a severe case of Vertigo.
