Hey all- I'm running an Intel HD 3000 graphics card on Fedora 16, 64 bit. My system seems to be using the VESA driver (Which is bad, right?) If I got into Display manager, it says the laptop screen is "Unknown." The system doesn't recognize any display when I plug it into my laptop's VGA port- but if it's plugged in when I turn my laptop on, it mirrors my laptop screen.

$ lspci | grep VGA (04-19 01:27) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

$ xrandr (04-19 01:27) xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 0.0* 800x600 61.0

How can I get everything working?

I would try setting everything manually. To do that first generate the modeline, for my old 1280x1024 TFT that supports refresh rates up to 75 Hz it is:

$ cvt 1280 1024 75
# 1280x1024 74.90 Hz (CVT 1.31M4) hsync: 80.30 kHz; pclk: 138.75 MHz
Modeline "1280x1024_75.00"  138.75  1280 1368 1504 1728  1024 1027 1034 1072 -hsync +vsync

Then tell xrandr about the mode, add it to the display and activate it:

xrandr --newmode "1280x1024_75.00"  138.75  1280 1368 1504 1728  1024 1027 1034 1072 -hsync +vsync
xrandr --addmode VGA-0  "1280x1024_75.00"
xrandr --output VGA-0 --mode "1280x1024_75.00"
