I have a problem I have never seen before and was hoping someone can point in the right direction. I have a thinkpad T61 with the Intel 965 Chipset / Video.
The problem is you can set the resolution if the LCD to the native and it will work fine. However if you try to use any usb flash/hd type devices it switch back to the 800x600 resolution. I can change it back to the native and use it however once another usb drive is inserted into the usb it does it again.
If I remove the display driver it stops this however I have tried all dif versions of the driver software and all of them do this. I have also have the lastest chipset drivers as well. I am not sure what else to try before I just reload the laptop and hope that that fixes it.
