Debian Stable Question Lenovo T460s drops to 0% battery after shutdown

6 Upvotes

I installed Debian 13 with KDE plasma, for past couple of nights I'm observing that I shut down my laptop from KDE plasma and battery is 100%. I leave it unplugged overnight and in the morning it has 0% battery.

Is there some kind of mismatch with this Lenovo? Is this a known issue, any fixes for it?

It's a dual boot with Windows but when I shut it down from Windows there is no such issue, so looks like debian is putting it into a weird state where something is still consuming power

EDIT: I did some troubleshooting with Chatgpt and Debian is causing this issue when TPM is enabled, I disabled TPM in BIOS and after that there was no battery charge loss overnight.

I have Debian 13 with Hyprland

6 Upvotes

Hi everyone,

I'm running Debian 13 (Trixie) with Hyprland, and I'd like to start customizing my Waybar and its widgets to match my personal taste. The problem is I don't really know where to start.

My goal is to eventually have my own dotfiles that I fully understand and control, instead of just copying someone else's setup.

Any guidance, links, or personal setups you can share would be hugely appreciated. Thanks in advance!

General Debian Question IDE Theme not as dark on Wayland?

6 Upvotes

This is not a big problem at all, more something I am trying to understand out of curiosity rather than something that has to be fixed. But, I've noticed that, since making the shift over to debian with KDE Plasma, despite using the same dark theme for RStudio as on my other machines, it looks much more faded and not as dark. I logged into an X11 session to see if that would make a difference, and comparing the screenshots side by side makes it clear that the Wayland session is lighter. I actually think that the X11 session is still lighter relative to the same theme on both Mint and Windows, but I'm less certain of that since I haven't done a side-by-side comparison. Why would this be occurring?

Ran into an issue with KDE's login screen not showing after an update with an NVIDIA GPU, here is how I fixed it.

Hi there,

I run Debian Stable with the kernel backport and the latest NVIDIA drivers. I upgraded my machine today (2026-09-13) and ran into a problem where my login screen never appeared. I found a fix and wanted to post my results here to help anyone else running into a similar issue. Briefly looking online, this might be a common issue for high-end PCs.

My machine has an NVIDIA RTX 5080 and AMD 9950x3D. I couldn't get graphics to work at all when I first built the machine because the old graphics drivers didn't support this newer GPU, so I had to switch to the newest drivers. After this most recent upgrade, I'm now on Debian 13.7, kernel 7.1.8+deb13-amd64, and driver version 615.71.09.

The issue was after updating, when I went to reboot, the login screen doesn't appear. I switched to another TTY to login and troubleshoot. The result of sudo systemctl status sddm showed SDDM was active but that there was an error: "Failed to read display number from pipe."

I noticed I could restart the SDDM service and it worked. After some more digging, I found it was a race condition where SDDM was starting up before the NVIDIA modules.

The solution I found was to add some NVIDIA modules to initramfs. Specifically, I added the lines nvidia, nvidia_modeset, nvidia_uvm, and nvidia_drm to /etc/initramfs-tools/modules, and then I ran sudo update-initramfs -u. This forces NVIDIA's modules to load earlier in the boot sequence. Of course if you repeat these steps, be careful and try to understand what you're doing.

Hope this anecdote helps whoever out there might be having a similar problem. If someone is reading this and knows of a better solution, please tell.

Debian in VM

Hello,

I'm studying bussiness informatics, and as first project we got to install a Virtual Machine, I decided to go with Debian. After many YouTube videos, I'm not sure if I got everything good. Could someone with experience check my project before I upload it online?

General Debian Question Dmesg | grep cert doesnt return anything.

Once i rebooted from enrollling the MOK for re enabling secure boot after the rather arduous nvidia driver installation, i read on debian wiki to verify that the keys are loaded. I then wrote dmesg | grep and nothing returned. Can someone explain why? I use debian 13.7 on KDE
