Flickering && glitching and random freezes after suspending the system

Hey this is something i noticed when i used manjaro in the past with kde + x11, and now i experience it with garuda gnome i don't really know if it is a problem with my old laptop or something else, whenever my system is put to sleep when i restore back flickering start and some random freezes(the display freezes for like 5 seconds), any idea

i also should say that i use electron apps looooot (teams, vscode, discord)

With those kind of persistent problems, I would update your bios first BIOS Update (Bootable CD) for Windows 8 (32-bit, 64-bit), 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP - ThinkPad T420, T420i - Lenovo Support US

If the bios update alone doesn't fix your issue, I would try out using the linux-lts kernel next.


question : should i download the file in the link and install it inside windows? i have no idea how to do it .
Thank u for the reply

The page certainly could try to instruct better, lol.

Let me try to explain a bit better. "The BIOS Update CD can boot the computer disregarding the operating systems and update the UEFI BIOS" -- this means unlike the other BIOS update method, you can download the latest ISO on that page and then make a bootable CD/DVD/USB with it (without doing it through windows like the other method). Make a bootable media with that ISO. Reboot your computer and hit whatever key your system prompts at startup to get to a boot selection and select your drive that your bootable media is in. The bootable media contains a way to upgrade to the new bios contained within it.

Apologies for the sloppy writing. I am away on a mobile device at the moment.


thank you very much for the explanation, i have already downloaded the iso file, i will put it in my ventoy usb and try to upgrade :heart:

Also looks like your battery might be on its last legs as its max charge is very low from its condition. Would explain the flickering under heavier loads.


i actually never thought about it causing the issue but now since u have said it i believe it is the reason why i a having that, thanks for that note
