There are problably a million blog posts telling you how to do it, but none of those guides worked for me. Things can often be different sites and other "unknowns", so there is no guarantee this works for you or for every site. First we'll use curl to search for all the relevant files for the domain and based on the snapshot/timestamp in bold below. curl -s "https://web.archive.org/cdx/search/cdx?url=yourdomain.com/*&to=2........

It may appear to be an Xorg or lightdm/gdm/mdm error but in reality for many users with this issue, it's a driver conflict and issue. I had a system that had two GPUs, an Intel and Nvidia GPU. The only thing that got it working was to remove the nouveau driver and blacklist it so it never came back, then the Intel GPU works fine without these issues. Solution sudo rmmod nouveau add nouveau/other driver to blacklist edit th........

Just find the relevant file in /etc/NetworkManager/system-connections sudo vi /etc/NetworkManager/system-connections/Wired connection 1 [802-3-ethernet] duplex=full mac-address=00:00:00:FE:FE:FE [connection] id=Wired connection 1 type=802-3-ethernet timestamp=1532403341 [ipv6] method=ignore [ipv4] method=manual........

Solution for me: My example uses 3 videos in total so "n=3" and a=1 to include audio. ffmpeg -threads 12 -i file1.mp4 -........

Install the "Editors" and "Net" groups that will give you rsync, ssh, ssh-keygen and cron. The trickiest thing that I keep forgetting about each time is you have to run "cron-config" which adds the cron service to Windows, and without doing that obviously no cron jobs will be run thus making automatic backups impossible. Warning about rsync/cygwin and using the -a archive switch. It's a good thing I caught this because it doesn't work ri........
