*help* several errors made. Is my SD image trashed?

irRegulator

Ok, this is my first build and I am new to Linux and Pi. All was going well. Loaded all my roms, got sselhp scraper working, messed with themes and was playing all my childhood favorites, great. I got a new case with a fan played with some overclock settings, still fine. Last night I shutdown the Pi3 and today I would only get a black screen on the console on the TV. I could still login via SSH Putty so i tried to launch ES and would get nothing. I tried to launch startx and got a series of errors. Im a few trouble shooting steps down the line but I will try to recall the steps taken and errors received. I had been seeing an error about my games list xml start and end tags not matching but everything worked apart from the metadata not loading on nes and n64. I was going to try to fix that today but was getting the black screen I mentioned.
I first was getting:

(EE) parse_vt_settings: Cannot open /dev/tty0 (permission denied)

I did this:

sudo apt-get install xserver-xorg-legacy

I got this error:
Only console users are allowed to run the X server

So I did this:

sudo usermod -a -G tty pi

And this:

sudo useradd -G tty pi;logout

Now I get this:

and it will not move passed this and I still get no signal to the TV.

Sorry, I know I'm missing many details that would help ID the issue but I am new to this and not sure what you would need.
Any ideas?
Thanks for looking.

@irregulator The main thing that jumps out at me is that you are trying to launch X, ie the Desktop environment via SSH. This is not going to ever work. Secure shell will not display the desktop.

jonnykesh

@irregulator Ignore that final part regarding trying to launch x via SSH, those are normal errors and seems to be distracting from the real issue. The problem is your lack of HDMI output / display. Post the contents of your /boot/config.txt file.

irRegulator

Thanks for the reply, I was trying to get the desktop or ES to launch on the tv not the ssh on the PC. I was able to initiate ES on the tv output from the PC before. I was hoping it would get me around the black screen.

@irregulator said in *help* several errors made. Is my SD image trashed?:

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

First thing to do is remove the hash here so it says.

hdmi_safe=1

then reboot. You should hopefully get a picture on your tv.

jonnykesh

@irRegulator If that doesn't work I would recommend removing all your overclock settings, reboot and see what happens. Where on earth did you get these settings from?

irRegulator

@jonnykesh
Thank you so much for helping me out. I will report back my findings. I think i found those settings on a N64 optimization writeup. Do they look a little wonky?

irRegulator

Ok, sweet, we auto-booted into ES and i have HDMI out. Super low-res now, however. As in SD output, i think i have it locked @720p though? Any thoughts? I owe you a sandwich @jonnykesh.

irRegulator

got it

hdmi_mode=82 1080p 60Hz

fixed
