i was stupidly repairing driver issue using this link https://help.ubuntu.com/community/SoundTroubleshootingProcedure
i think i was here
sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install pavucontrol linux-sound-base alsa-base alsa-utils gdm3 ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm3 ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; ubuntu-support-status || ubuntu-security-status; sudo usermod -aG `cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami
and i might issued "reboot" before the troubleshooting commands finished, i have access to xfce session but not graphical interface, when i boot the pc ( hooked to the TV) I'm faced with GNU GRUB i tried to go to recovery mode and file check and file repair without luck, i tried this Stuck at GRUB command line with no luck too!!
i have root access to the terminal through xfce session which i run from my laptop using Chrome remote desktop, the monitor hooked to pc is black blank with little white blinking dash in top left corner
ETA:i can run xfce remotely, but I can't Access Ubuntu desktop (native GUI ie. the PC)
i can access tty2-4 and login but when i switch back to to tty1 i have black screen
