For the first time I am actually switching my main PC from Windows to Linux.

Problem: When booting into Fedora there was no display output, I changed it to safe graphics to install everything and that fixed it but after the install finished I tried turning it back off and there was still no display output

What I have already tried: I’ve tried installing drivers and everything I could find although that shouldn’t be the problem since I have an AMD 6700xt and Fedora comes with AMD drivers built in. I also tried Installing Linux Mint thinking maybe the distro was the problem but it came up with the same issue.

And if anyone suggests it no there is no way I am going to daily drive on safe graphics.

Edit: I am dual booting on a single 500gb ssd with windows already installed on the other half of the drive, not sure if that would be the problem. Also a similar problem was happening on windows if I left the screen in login for too long without signing in the display would show no signal and it wouldn’t wake up if I moved my mouse or clicked or pressed any keys.

    My bet is it tries to default to mode that your display doesn’t like, probably because of some wrong info in monitor’s EDID downloaded from the connector, but that’s just my guess.

    Before booting, use key e on grub menu, locate line where there is initrd to pass boot parameters. You can force modes using video= parameter, and you can also replace/modify your EDID. Refer to section # Forcing modes and EDID on this page: https://wiki.archlinux.org/title/Kernel_mode_setting

    These changes can also be achieved permanently by editing /etc/default/grub and regenerating its configuration, in case you use grub.

    Easiest would be to have separate extra monitor temporarily or another computer to connect over SSH, but if those low “safe” graphics modes work, that can probably do also.

      Yeah that sounds promising. I have read the wiki page and I tried a few boot commands I followed this guide Here is what I have added to the boot manager screen:

      (without additions)

      GRUB version 2.12 load_video set gfxpayload=keep insmod gzio linux (sroot) /vmlinuz-6.11.6-300.fc41.x86_64 root=UUID=5еа3757а-72ac-492-9832-50b00b68f405 ro rootflags=subvol=root rhgb
      quiet amdgpu.si_support=1 amdgpu.cik_support=1 initrd (sroot) /initramfs-6.11.6-300.fc41.x86_64.1mg stuned_initrd Minimum Emacs-like screen editing is supported. TAB lists completions. Press Ctri-x or F10 to boot, Ctri-c or F2 for a command-line or ESC to discard edits and return to the GRUB menu.

      It didn’t work but I think it might be because I am doing something wrong here.
