sudo mount /dev/sdXY /mntsda1 is the primary ext4 (root)sda2 is the extendedsda5 is swapsdb1 is the cruizerso Code: [Select]sudo mount /dev/sda1 /mnt*note the space after the 1 and /mnt
sudo mount /dev/sda1 /mnt
*********************************************************************************************************************************EDIT: firenice03 responded before I finished and posted this. Try that solution first -- it's easier than my instructions below, but is doing exactly the same thing.*********************************************************************************************************************************I don't know a lot about fixing graphic card issues, (so can't be much help with that), but I can help you reverse what you did according to that link.Hopefully you still have the live install dvd/usb that you used to install LL. If not, make another.Boot computer with your live dvd/usb.Open a terminal and enter this command to list the partitions on your hard drive.Code: [Select]sudo parted -l (Command ends in a lowercase letter "L", not the number "1".)Find your LL root partition and make note of which partition it is (eg. /dev/sda1, /dev/sda5, etc.). Assuming you did a standard installation that results in one root partition and one swap partition, just look for the partition that shows "ext4" under the "File system" column of the output. If you have a root/home/swap setup, you'll see two with "ext4". The smaller of the two partitions will be the root partition in that case (unless you have a very strange setup).Substitute your correct partition in place of my example of /dev/sdXY in the command below. (X is the drive letter -- eg. a,b,c -- Y is the partition number -- 1,2,3. Command will mount the root partition to the live environment so you can get to the file you made from that tutorial.Code: [Select]sudo mount /dev/sdXY /mntNow we'll just delete the file you made in tutorial so it doesn't get used on further boots. Enter this command to do that.Code: [Select]sudo rm /mnt/etc/X11/xorg.conf.d/20-amd.confNow unmount the partition with this command.Code: [Select]sudo umount /mntShutdown, remove live dvd/usb, boot back up and should be back to way it was before that change.
sudo parted -l
sudo mount /dev/sdXY /mnt
sudo rm /mnt/etc/X11/xorg.conf.d/20-amd.conf
sudo umount /mnt
If can't access the tty - try gold_fingers suggestion ...
I put my username and password correctly but it still incorrect. What to do?
sudo systemback-cli
Try after it has boots to the blank screen...Press CTRL + ALT + F1You should come up to a tty1 screen prompting for login... Do so.. You will be at a command prompt... From there try the commands suggested to revert:After reboot, you will find screen tearing has been eliminate. If you wish to revert the changes, open the terminal and add the following:Code: [Select]sudo rm /etc/X11/xorg.conf.d/20-amd.confCode: [Select]sudo reboot
sudo rm /etc/X11/xorg.conf.d/20-amd.conf
sudo reboot
An additional thought... Have you configured/added any additional graphical themes/functionality - Compiz etc..??- If so, perhaps setting back to a LL default config to confirm if issue persists.. Here are a couple threads regarding AMD and LL that may enlighten.. https://www.linuxliteos.com/forums/start-up-and-shutdown/shutdown-problems-andor-sluggish-system-w-amd-graphics/msg20292/#msg20292https://www.linuxliteos.com/forums/video-cards/amd-drivers-which-to-use/msg24811/#msg24811
To me... That sounds more related to the graphics driver... Shadowed/delayed/ghosted images, more so as if the the video is refreshing slower..If you wanted to update the video driver, I would make a systemback backup as the first thing.. If the updated driver doesn't work you can easily revert back.Give the manual a read https://www.linuxliteos.com/manual/hardware.html#graphicsThen you could check in the Install Drivers (type from menu) to see if any better drivers are available.. (listed in the manual)As well as searching the forums for ATI or AMD or Radeon for hits..
