I installed Fedora 15 on a notebook, however when I plug in an external LCD monitor the resolution can only be set to 1024x768 or 800x600.
This is what I know about the problem so far:
- the notebook has Intel HD Graphics and Nvidia GeForce 310M
- processor is Intel i3 M370 @2.4GHz
- attempting to install drivers for the GeForce caused GNOME3 to fail to load (had to reinstall)
- I installed Fedora from a Live CD
- the LCD monitor appears as "Unknown monitor" to the system
How do I get more options to change the resolution?

You can try setting your resolution to the desired level manually.
First, run this command, changing the example 1920x1080 resolution to the resolution you want:
cvt 1920 1080 That will spew out something like this:
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync We're only interested in the chunk after the quotes and before the -hsync, e.g.
173.00 1920 2048 2248 2576 1080 1083 1088 1120 Use that in the next command to add a graphics mode:
xrandr --newmode clever_name 173.00 1920 2048 2248 2576 1080 1083 1088 1120 Now, add your new mode to your VGA output:
xrandr --addmode VGA1 clever_name Finally, switch your VGA monitor to use it:
xrandr --output VGA1 --mode clever_name
