Change resolution console and X11 to 1024x768 FreeBSD v11

Hi all,
I've installed FreeBSD 11 on my Raspberry Pi. How can I change the console resolution and X11 to 1024x768?
Cheers,
Rob
 
Thanks I just saw that one and I've installed those packages. I can open X11 but the resolution is pretty big. How can I force 1024x768? Changing the /etc/xorg.conf ?
 
The scfb driver ignores the "Screen" section of the xorg.conf files. From scfb man file:

Code: 
For this driver it is not required to specify modes in the Screen
section of the configuration file.  The scfb driver picks up the
currently used video mode from the framebuffer driver and uses it.
Video modes specifications in the configuration file are ignored.

Also, xrandr will only show the currently used screen resolution. At least on a Raspberry Pi 3 it might be impossible to change it.
 
If I run xrandr it says: Can't open display. Not sure if this is due to it being a Raspberry Pi B? Has anyone successfully changed the resolution on a Raspberry Pi?

Also is there a way to force a window size for an App when launching it? Ive got one app which opens so big with this resolution I can't use it properly.
 
What window manager are you using?
It can be done in the window manager configuration files.


With Alt + Space you might get the window options, then go to resize, and resize with arrow keys.

What is the default resolution?

I just fired up my RPi B and the default xorg screen resolution is 1824x984.
 
Mine must be lower than 1024x768. How did you change it? Please share going crazy here trying many combos.
Thanks,
Rob
 
Here's all that I think may be relevant (FreeBSD 11):

Code: 
Section "Monitor"
    Identifier  "Monitor"
EndSection

Section "Device"
    Identifier  "Generic FB"
    Driver      "scfb"
    Option    "NoAccel"    "True"
EndSection

Section "Screen"
    Identifier  "Screen"
    Device      "Generic FB"
    Monitor     "Monitor"
    DefaultDepth 16
    SubSection "Display"
       Depth     16
    EndSubsection
EndSection

And config.txt:

Code: 
disable_commandline_tags=1
gpu_mem=32
hdmi_force_hotplug=1
device_tree=rpi.dtb
device_tree_address=0x100
kernel=uboot.img

My monitor is a BENQ G2420HDBL (24" wide screen, resolution 1920x1080 @ 60Hz).
 
I have a /usr/local/etc/X11/xorg.conf file and config.txt goes in the MSDOS boot partition (there should be one already).
 
hmmm Xorg looks in /etc/xorg.conf on my install. I've added your comments above to that file and also to the config.txt. I get this error.

My monitor is a Dell 2011H 20" with a native res of 1600 x 900 at 60 Hz. Any ideas?

Xorg looks in a number of locations, doesn't mean this is the correct one on FreeBSD though. Move it to /usr/local/etc/X11/xorg.conf so it's at a known and expected location.
 
Using this hack in the config.txt seems to force the X11 resolution too:

R-Pi configuration file - eLinux.org

elinux.org elinux.org

# Uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

Thanks for all your help everyone.
