Hi!
I have little to no information on the causes of the issue I’m about to describe, so I will still try to give as much as information possible. Feel free to ask for more details.
I maintain casual NixOS configurations for two of my relatives: they are outputs of my own flake with casual oriented configuration. They include:
- User friendly desktop experience with KDE Plasma
- Non declarative
flatpak+ Flathub availability with Discover as GUI - Auto-upgrades pulled from my repository
On both of these 2 setups, which are laptops, I noticed something strange: occasionally (between 10 and 25% of times, arbitrary estimation), at KDE Plasma launch, the inputs are totally unusable. This affects at least mouse, trackpad, and keyboard. Note that everything in SDDM works fine, it’s when the login process is complete and when KDE Plasma starts that problem begins. The only solution to exit this is to force poweroff with the power button.
Among the two, the only computer I can manipulate right now is an HP ProBook 640 G4, so let’s focus on this one. The flake where I maintain the configurations can be found here: https://git.ahur.ac/ahurac/hosts. The output is named confuter and all the declarations can be found in the paths /hosts/confuter and /modules of this repo.
Note that my personal computer (desktop) runs KDE Plasma with a “non-casual” configuration (output ahrc-pc), with SDDM and all and has no such problem, which I find even stranger. I also own a HP ProBook 640 G4 (another one) with a “non-casual” configuration (Niri, greetd) and it has no such problem as well.
I’m so confused about this, I hope somebody will be able to know what’s going on. Thanks in advance!
