In the welcome app you can select akm in the additional software and install linux-lts. Here are more infos
Then when you reboot you can select lts
Edit: I also note that you run i3wm. Any other DE installed on your system or only i3?
Edit 2: in that case you would see what kernel is installed and could select linux-lts and linux-lts-header. Alternatively these can be installed via terminal.
I generally do none of that stuff and I don’t really trust Reddit posts, first source of infos better to use arch wiki. I also run several Thinkpads and they run fine without additional power or graphics tuning…
Not sure what got broken, probably the additional fiddling with Intel driver in step 4). Difficult to say.
Approach to problem would need to be different. Perhaps post that piece of info at the top of this thread too.
Keep us posted but screen freeze are often due to graphics drivers issues. Sometimes new drivers in the kernel don’t play well with some hardware, then lts can possibly fix some issues. But the question is whether you had any issues upon eos install to begin with, before doing the steps recommended in the Reddit post.
My understanding is that this post maybe geared towards hardware with Nvidia and and GPU. If you can’t get the help you need here, my suggestion would be to reinstall eos and then check if you get any system freezes if that is an option.
Then would be faster and easier to troubleshoot the cause. I also have a t490s, almost similar to 480s I assume, and no problems in general with eos out of the box.
What do you mean by hardware acceleration anyways? I use my ThinkPads without any additional packages and performance works flawless, cpu, ram and Intel graphics. Do you mean for GPU like Nvidia?
No im not talking about nvidia, it really doesn’t matter what gpu you have, you can use VAAPI to for example hw accelerate videos in Browser.
On for example laptops its a good way to make your device perform better and not blast all the fans at full force when watching for example 4K content on different services (Youtube etc etc).
