The problem occurs both using an external monitor (Acer AL1715) attached to my laptop and using only the laptop monitor. When I try to change resolution from 1366x768 to 800x600 or 1024x768, the screen goes black, after about 20 seconds the screen goes back to the original 1366x768 resolution. Tha log file attached in #6 was made using my laptops monitor (my laptop is a HP G-62). Must I send you the same log with the external monitor attached ?
