Use Driver Booster, a great driver manage tool which helps to update and backup your drivers easily. To solve this problem effectively, we can try the following solutions.ġ Check your graphics card version in Device Manager, Win+R, input: devmgmt.msc Ģ Go to the official website of the graphics card vendor and find out a proper one ![]() This may be caused by the inefficiency of the graphics driver on your laptop, so you need to update or re-install it manually or through a driver tool.

And no "tools." update suggested.Īnother fun stuff about kernel 5.13 is the "SGX disabled by bios" message at boot I didn't had with kernel 5.4.Īfter some search, it doesn't seems to be bad, but after disabling SGX in Bios, I still have the message.How to dim screen of my laptop when holding Fn key with brightness key is not working So I tried from scratch to reproduce the behaviour (and maybe make my brightness keys work again).įresh Mint (20.3) install, Kernel 5.4 : brightness keys not working (expected) I did the update (I'm an up-to-date freak), and keys weren't working anymore !

The system will not automatically up grade your kernel if the kernel you are using is still receiving support. Switching to a newer kernel series (such as 5.13) is considered an up grade (as opposed to an up date). Therefore, if someone has newer hardware, they often need to use a newer kernel to get the newer drivers and features. However, while it gets bug fixes and patches for the entire time of its support, it does not get any new features. It contains features and hardware drivers from when it was initially released several years ago. I was using Kernel 5.4.0-99.Īnd you tell me there are newer kernels, why did the kernel didn't automatically updated with the rest of the components ?The 5.4 kernel is the LTS (long-term-support) kernel for Linux Mint 20 and will receive support until April 2025. rebooted, luminosity buttons wheren't working. ![]() Wed 10:58 amThe thing that i don't understand (i'm new to Linux and Mint) is that I installed Cinnamon 20.3, and made all the updates.
