raspberry pi 2, hdmi not working

[nomoi]

monitor is an lg tv (got no hdmi monitor yet)
android device works fine with the monito, but not kali.
i can connect via ssh. so it's just the hdmi issue.

found this one http://rageweb.info/2013/11/07/vcgencmd-on-kali/

but haven't tried it yet, since it's not especially for the image of offensive security for the rpi 2.

the /boot/config.txt shouldn't work.

greetings

What do you mean the /boot/config.txt shouldn't work? vgencmd is just a helper app to make it easier to edit the config.txt file - you can do it manually, or you can add those - I'm debating importing them in to Kali, but I'm more of a "just edit the text file" guy myself.

[nomoi]

no, in the posts around that, they stated that its not sufficient to edit the text file. because its not booting from there. so if there is no textfile its not helping to create one. because its different from rpi1. i didnt fully understand it, but just that i need an alternative. if you got a simpler solution i m open for that

in kali config.txt is placed in /media/root/random number of the flash card/config.txt

booting from there or not, I'm totaly able to edit settings/changing resolutions/attaching i2c or spi modules etc.

command is

nano /media/root/random number of the flash card/config.txt

to identify the number type cd /media/root then enter the ls and again enter

then remove # to activate what you want and hit Ctrl+O then Ctrl+X then reboot.

After that check if there is a hdmi signal.

I also have LG tv with hdmi.

here's my config for reference, the underlined text is the functions to check for your case one by one:

# For more options and information see
# http://www.raspberrypi.org/documentation/configuration/config-txt.md
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
framebuffer_width=1280
framebuffer_height=720
framebuffer_depth=32
framebuffer_ignore_alpha=1

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

I don't have anything in my /media directory. There is no option for /media/root
Also, no /root/media option. I'm still fairly new to Linux, so is there another place startup files could be stored?

Open your file manager and browse the 64 MB volume.
Do you see the config.txt in that directory?

mikrostart: i think he's looking on the rpi itself, not on another kali box, which would explain why he doesn't see those mount points.

[mikrostart]

It should be on the same Pi. But instead with the file manager, the terminal window should be used.
And not looking in the left panel with file manager's options.
I think that's the point.

Similar problem. After downloading kali to a 16gb samsung card and initial boot my Rpi 2 recognized the LG tv fine, now I get the rolling text then nothing, just an innactive cursor in the top left.No go on a Samsung tv either. Another problem I had when it worked was lock ups requiring unplugging at the wall, could this have corrupted the card? The Pi doesnt show on the router so I cant ssh. Any help appreciated for this novice
