Step 4: Open Ubuntu Mainline Kernel Installer (just search it)
Step 5: Install the kernel you want (I installed the last 6.07)
Step 6: If you disabled grub's timeout reactivate it with grub-customizer (here you can also add intel_iommu=off to GRUB_COMAND_LINE in an ease way), so you can choose the old kernel if things go wrong
I installed 6.07 and added intel_iommu=of, but I took my precautions when using it. I did a complete backup of my system before (you can install timeshift if you don't know how).
I have a Toshiba C845 with 4 cores i7-3632qm with CPU power manager with top speed 2.9 - 3,2 ghz with 2 displays working and upgraded from 20.04 to 22.04
I saw improvements, but most after enabling again xorg. Seems old generation intel processors are better with it.
Nevertheless, the system is not as fluid as with 20.04 . For me it seems that gnome 42 improved design is more resource hungry than gnome 32.
Seems for my hardware is not worth updating. I also did a backup before upgrading so I think I will return to 20.04.
Hi to all,
In this tutorial you can find a way to upgrade linux kernel in a not so dificult way: https:/ /linuxhint. com/install- upgrade- latest- kernel- ubuntu- 22-04/
In a nutshell:
Step 0: I recommend to do a backup before (using timeshift or other app)
Step 1: sudo apt update
Step 2: sudo add-apt-repository ppa:cappelikan/ppa -y
Step 3: sudo apt install mainline -y
Step 4: Open Ubuntu Mainline Kernel Installer (just search it)
Step 5: Install the kernel you want (I installed the last 6.07)
Step 6: If you disabled grub's timeout reactivate it with grub-customizer (here you can also add intel_iommu=off to GRUB_COMAND_LINE in an ease way), so you can choose the old kernel if things go wrong
I installed 6.07 and added intel_iommu=of, but I took my precautions when using it. I did a complete backup of my system before (you can install timeshift if you don't know how).
I also disabled thermald, uninstalled power-profile- daemon and installed cpu power manager extension from gnome.extensions (https:/ /extensions. gnome.org/ extension/ 945/cpu- power-manager/) to configure it in the higher cpu frequency.

Hope this help!
