Description Stefano Rosellini 2008-07-17 09:22:54 UTC 
Created attachment 17727 [details]
Log of X started with attached monitor.

Environment Mandriva 2008.1 on Fujitsu/Siemens laptop with Intel GM965 graphic chipset.
All works perfectly, but if I attach an external LCD monitor (tested with various models, 15, 17 and 19 inches) the resolution fall to 640x480 (or maybe less?).
