resolution problems

When I play an SDL game such as Nexuiz or Frozen Bubble, it won't correctly switch to a resolution that is lower than the first value specified in /etc/X11/xorg.conf. Instead, it stays in the first resolution, but paints a rectangle the size of the resolution it should be in at the center of the screen. Also, kcmshell display only displays one resolution and Ctrl Alt +/- don't work.

This is with Xorg 7.

My /etc/X11/xorg.conf:

# Xorg configuration created by system-config-display

Section "ServerLayout"
	Identifier     "single head configuration"
	Screen      0  "Screen0" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"

Section "Files"

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, a font server independent of the X server is
# used to render fonts.
	FontPath     "unix/:7100"

Section "InputDevice"

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
#	Option	"Xleds"		"1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
#	Option	"XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#	Option	"XkbModel"	"pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#	Option	"XkbModel"	"microsoft"
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"
# If you'd like to switch the positions of your capslock and
# control keys, use:
#	Option	"XkbOptions"	"ctrl:swapcaps"
# Or if you just want both to be control, use:
#	Option	"XkbOptions"	"ctrl:nocaps"

I have tried using my xorg.conf from FC4, which it worked in, but nothing changed.

I looked at which suggests that my monitor (Envision EFT 720) isn't supported by Xorg anymore. Is it?

I'm not sure what would be the problem, but I doubt that if your monitor model isn't officially supported anymore you can't get it to work properly with generic drivers.

So, maybe you could try that, switch to a generic driver that matches your monitor best. You can use xorgconfig to generate a file for you.
