I have had a bad day.

Among today's events, the LCD display on my Dell E6500 notebook failed. It had been working with a secondary monitor connected through a VGA cable at 1600x900 resolution until I removed the LCD from my notebook for repair.

Now the max resolution available on the secondary display is 1024x768. If I reconnect the burned out primary display, the secondary monitor is again available at 1600x900.

The video card is an onboard Mobil Intel 4.

How can I maintain the secondary display at 1600x900 with the primary display disconnected (for repair)?

Edit: I just noticed that when Windows boots, it displays at the correct resolution and I can see my desktop in all its glory for a couple seconds then reverts to 1024x768.

Why does my laptop resume immediately after suspend?

I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after.
