And i'd like to change that xorg.conf file so how would i go about that?
The file is in the directory /etc/X11. Directory means also "folder".
The first "/
" means the upper level of the directory tree. It is similar to "C:\" in Windows. Following the path you should find the file.
You have to edit it with root
So open from the menu the file manager Dolphin (or another if you prefer) in root mode. You will be asked about your root password.
Find the xorg.conf
file and copy it giving it another name, let's say xorg.conf.original
. This is a back up. If something goes wrong you can always rename it to the previous name and the system will use it.
Now open the xorg.conf
file for editing and replace the lines between
with the lines copied from the link I posted.
Save the file, reboot and cross fingers...
If something is wrong you probably won't see the usual login screen but rather the system will ask you if it should repair the situation. Choose yes in every step an you should
be back to the initial state.
If not you can boot the machine from the LiveCD that you installed from and rename back the back-up file xorg.conf.original
, again with a file manager in root mode. You can enter the forum from LiveCD too.
