First off to do this correctly a few things need to be in place in case something goes way wrong
#1 goto software store and download an app called TimeShift this is important as it will help restore you back to where you were in the event something goes wrong
#2 you will need to be able to see the zorin boot menu if by chance a kernel panic happens.. to do this in the terminal type
sudo nano /etc/default/grub.....
you may to install nano with sudo apt install nano
once in the grub area change it to look like this
use the arrow keys to get down to line you want to change move past the word then backspace it out when done i move all the way to bottom using the down arrow till it stops should look like this
then hit control+o then enter then control+ x
then in terminal sudo update-grub
make sure to do this or it will not change it in the grub
Ok now this is mainly for folks using OS 18..now at this point you should have timeshift installed and have created a new timeshift
now we need to install mainline which has all the current kernels that is used in ubuntu based distros like zorin open a terminal and type
sudo add-apt-repository ppa:cappelikan/ppa then
sudo apt update && sudo apt install mainline -y
this should install mainline onto your laptop/computer
now lets open mainline you will see lots and lots of kernels in here so before you get all excited and go way to top and download 7.0 and greater you need to upgrade in smaller steps jumping to newest kernel from say 6.17 to 7.0 WILL cause a major problem that may require a reinstall...
in order to do this right if your using the 6.17 kernel go into mainline and look for the 6.18 kernel should be the first one you see in the mainline list...i know there are a few others there but lets not get ahead of our selfs for now lets install just the first one 6.18 generic this is step one in a few steps to find the best kernel for you system
to install 6.18 simply click it then to right side you will see the install button is now lite up click that and it should install the 6.18 kernel there souldnt be any errors on the install screen. if that is so then restart and in a terminal type uname -r it should show kernel 6.18.xxx generic
now do a sudo apt update && sudo apt upgrade
if that goes through with no errors then all is upto date.. now after open a few things apps games and stuff and see if all is working ok test to make sure internet is working and sound as well as all of the stuff that was working in the previous kernel if all is stable at this point and its running smoothly then this maybe the kernel you need and i highly suggest staying here for now
So if all is stable at this point we can now goto the next step in the mainline click 6.18.3 and install it if it installes with no error again restart then run uname -r to make sure it did install correctly if it did do the same as last step and see if everything is working smoothly... if this is working better then last one this maybe a good time to stop as well this maybe the kernel you need if its not stable or you got a kernel panic go to the boot menu then advanced and choose the lower kernel you was on and let it boot up into that one then open the mainline you will see in the list one that says running...then above it is the kernel that had the panic click the 6.18.3 one as it was the error one then to right click uninstall
as the 6.18 generic is the best your system can handle...but if it was stable we can now jump into 6.19 the first one just like when you jumped to 6.18 .... 6.19 generic
then to right same thing hit install let it run till done with no errors if there is errors then 6.18.3 is your best kernel for your machine if errors click it then uninstall
now same as last time if it installed without errors this time restart and make sure it boots ok...if it did then so just like last step run stuff to make sure all is stable if so you can stop at this kernel as its working fine and do the
sudo apt update && sudo apt upgrade to make sure its upto date
Ok so if everything is working ok and you feel it could maybe be better and your machine is PCIE 4.0 and greater at this point we can take the next step by installing 6.19.3 same as all the steps so far ...just click it then to right the install button making sure it installed without errors if errors uninstall and 6.19 is you best best kernel for motherboard you have..if it did without errors then restart then uname -r to make sure 6.19.3 is showing. as with last steps make sure system is running stable and smooth and all is working as expected.. if so and you feel its working correctly then skip the next step as this maybe the kernel that works with your system
Now all this so far is how i did this on my system to get to this point without to many problems. now for the final step, first let make sure we are upto date with
sudo apt update && sudo apt upgrade
now we need to install another repo in order to get the Liquorix kernel in terminal type
sudo add-apt-repository ppa:damentz/liquorix ........then after
sudo apt install linux-image-liquorix-amd64
at this step it may take some time as it will need to download the headers and the image for the linus kernel...as with all the above steps make sure it has no errors when it finishes. this may be awhile as it installs alot of goodies for the Pcie 4.0 and Pcie 5.0 motherboards and the more modern hardware 2021 to 2025 once it finishes it should restart if it starts without a panic welcome to liquorix run the uname -r to make sure it installed the see if system is stable running serveral apps and maybe some games to see if all is working.. now open software updater let it finish and click settings then open the other software tab and remove the Cappelikan repo from there as it is no longer needed if you wish to stay at the current kernel lvl you are at in liquorix then also remove the damentz repo as well and it wont update any farther.. hopefully all went well and hope this was helpfull in geting the liquorix kernel installed....enjoy
