I've had LibreElec installed and running for a while now, on several machines. I recently updated one of my PC's in my house and had this AMD Radeon HD 4850 graphics card just left over, and I thought that would be great to get some 1080p files to play on this one particular PC I have LibreElec installed on (it had a generic $20 HDMI out graphics card and chugged at 1080p files). Then my troubles began. Through searching this forum for hours, I found a few threads with very similar issues, and I found one particular thread that suggested that I could just do these two simple steps, it may fix my problem, two command line prompts:
rm /storage/.config/udev.rules.d/97-xorg.rules
touch /storage/.config/udev.rules.d/96-nvidia.rules
However, where I'm stuck, my system is stuck at a screen that says:
LibreELEC (official): 8.2.5
[FAILED] Faled to start Xorg Server.
See 'systemctl status xorg.service' for details.
[DEPEND] Dependency failed for Fluxbox Window Manager.
[ OK ] Reached target Graphical Interface.
Starting intel switch to full range...
[ OK ] Started intel switch to full range.
Starting Kodi Media Center...
[ OK ] Started Kodi Media Center.
[ OK ] Reached target Kodi Meidacenter Interface.
And it's just frozen. I tried initially just to install the card into the already configured LibreElec install, and then I tried a fresh install, and same effect. I've tried rebooting several times and get the same effect. Coincidentally, I notice that when I first boot the PC now, I get the normal startup text on the screen (telling me about the BIOS info, what drives it detects, etc), and then the screen blanks for a minute, and my TV says no source for a second before the LibreElec logo shows, and the above message appears.
How exactly do I execute the commands to disable the nvidia udev rule if I can't actually get into the machine?
Thank you for reading!
