1st thing to check is after installing updates, is to check "Install Drivers"
You can find this on the Welcome Screen, Menu (type the name)..
Under the Additional Drivers you may see additional drivers for your system...


Under Control Panel:
Also for video - you may want to check "Display" and can try different resolution/refresh configurations.


"Mouse and Touchpad" also listed - Under devices, next to device on the far right ensure button is enabled.


"Power Manager" which you've found, you can adjust the settings in the tab.
My laptop is still on LL4.8 but I believe the screens/functionality are the same...


Any of the programs listed or on the system can also be searched - click the menu button and type the name... i.e. type Lite and all the programs specific will resolve.


One other piece of advice - I would make a backup via TimeShift, is like a Last Know Good Config..
Should you attempt to install drivers or apply fixes to correct the hardware - you can easily revert back to the current/pre state.
Then once you're happy - you can delete the old and make another back up...


Keeping in line with easy fixes or those easily reverted...
What I would try next, is a newer kernel.. Your using 5.4 perhaps a newer kernel..
Search for "Lite Tweaks" then "Kernel Installer".. I would maybe try 5.8 then 5.10 or 5.12 .. you dont have to try each one.. BUT I would try the lower then next higher = so when you reboot (you'll have to) you will automatically boot to the HIGHEST...


You can remove old kernels with "Kernel Remover" in tweaks...
FYI WHEN REMOVING...
You cannot remove the in use kernel - safety net as to not break system...
IF the new kernel does not work or the system does not like it (say things stop working)..
Return to the last working kernel by rebooting - then on the "Grub Screen" - choose "Advanced" then choose the desired kernel (5.4) ...


To confirm what kernel you're using/booted to

Code:

uname -r

If you want to try an older kernel = same as above but you'll want to choose the "Advanced" on grub to select the older..


If joy is found - you can use "Kernel Remover" to any other tested kernels... But I'd keep 5.4.xxx -- I like to keep the previous kernel or 2 just to make sure all is good


** This sounds like a lot - but its not really **
LL has simplified a lot of this functionality and is all GUI based (less the 1 command I provided)


And every listed here is easily recoverable.

It says "no additional drivers available" in Additional Drivers.

Mouse and Touchpad only lists the external mouse I'm using in the drop-down menu.

All newer kernels I installed with the Kernel Installer say that is has an "invalid signature" and that I need to "load the kernel first" at start-up.

I just bought a Lenovo Ideapad 3 15ITL05 laptop

Is this your laptop? https://www.coolblue.be/en/product/87844...zerty.html Well, if that's the case, it uses the Intel Iris Xe Graphics processor and you might want to read here https://dgpu-docs.intel.com/devices/iris...index.html An excerpt:

While support for the Intel Iris Xe Graphics processor has already been integrated into Linux* and integrated into Linux-based distributions such as Ubuntu 20.04.1, enabling work for the Intel Iris Xe MAX graphics processor in Linux* is ongoing.

In that same link, they

provide early access to that software and instructions to configure an Ubuntu 20.04.1 system so you can take advantage of both graphics adapters today.

Which are not trivial. I think that's the issue; the driver for that GPU isn't being loaded, and your inxi output kind of confirms that cause it says:

Code:

Graphics:
  Device-1: Intel vendor: Lenovo driver: N/A bus ID: 0000:00:02.0
  Display: x11 server: X.Org 1.20.13 driver: fbdev
  unloaded: modesetting,vesa resolution: 1920x1080~77Hz
  OpenGL: renderer: llvmpipe (LLVM 12.0.0 256 bits) v: 4.5 Mesa 21.2.6
  direct render: Yes

It should list the driver as:

Code:

driver: i915

At least according to that link I shared above. Instead, it's using the fbdev driver https://www.systutorials.com/docs/linux/man/4-fbdev/

fbdev is an Xorg driver for framebuffer devices. This is a non-accelerated driver, the following framebuffer depths are supported: 8, 15, 16, 24. All visual types are supported for depth 8, and TrueColor visual is supported for the other depths. Multi-head configurations are supported.

I would try a new kernel, 5.11+ and see if that makes things better.

I didn't wanna try this Ire Xe solution because it says it's for Ubuntu 20.04 (I'm using Linux Lite) and already messed up one OS trying another "Tear-free" tweak I found on other sites. I really don't wanna reinstall the OS again, lol.

------

Some have said that if you switch from Xorg to Wayland, that can also fix screen-tearing, but have no idea where to go in Lite.

Also, can anyone help me figure out hot to do the following:

- Figure out how to install the Synaptics driver. It seems to be missing and is what the problem is with the touchpad not working at all.
- How to use the HDMI output to connect to an external screen. I was able to mirror it with Windows 11 with ease, but get "no input" with Linux.
- Enable the F11/F12 buttons to adjust screen brightness.
