I have just changed from a CRT monitor to a new LG 15" TFT one. Before I changed, I was running the old monitor at the same settings as the new one requires - 1024x768 at 75Hz. The new monitor works correctly both in Windows98 and Libranet. I didn't have to change anything in Libranet, the new one just worked. However, it doesn't work in SuSE8.1. I can boot and everything looks correct. When it gets to the part of the boot process where KDM starts, the screen goes black and I get an error message: INPUT SIGNAL OUT OF RANGE. Then, nothing else happens. Booting into text mode, to try to run the text mode version of Sax2 (to see if I could find anything wrong) goes well until the prompt. Typing "Sax2" makes the screen go black again with the same error message and then nothing. So I can't run Sax2 to check anything. As I said, the new settings are the same as the old ones. So I can't understand why it won't work in SuSE. I can't find any answer to this problem either in the manuals or in the list archives. Please can anyone give me some advice? Many thanks Keith
