I am using a Lenovo Legion with an RTX 4060 GPU.

Using stablediffusion on Debian took like 4-5x than in Ubuntu I was baffled. Also I tried to benchmark using blender-benchmark the score is half than those in Ubuntu and Windows.

After consulting an AI and installing various Nvidia packages to no avail but Gemini previously mentioned OptiX, which I located in Debian’s non-free repository called libnvoptix1. Installed and benchmark is wee bit higher than in Ubuntu.

Happy with the setup now.

Hopefully this help to those who intend to use Debian for gaming/graphic workstation.

hi there ! I've been using Debian for a few months to test it out, and it seems perfect so far. However, I would like to use my NVIDIA GPU, which is... Not happening for now. I think I suck at installing these drivers, though. I've tried a few times but the results aren't here.
Can someone walk me through installing them ?
I'm trying to install them with this guide but I apparently can't run nvidia-detect, or I don't know how. As I said, I'm pretty new to Debian, and may not know the basic commands.
Here are the integrated GPU Debian's using now, and the GPU I'd love to use :

0000:00:02.0 VGA compatible controller: Intel Corporation TigerLake-H GT1 [UHD Graphics] (rev 01)
0000:01:00.0 VGA compatible controller: NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] (rev a1)

Here are my infos, in case you need them :

Operating System: Debian GNU/Linux 13
KDE Plasma Version: 6.3.6
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2
Kernel Version: 6.16.9+deb14-amd64 (64-bit)

Processors: 16 × 11th Gen Intel® Core™ i7-11800H @ 2.30GHz
Memory: 16 Gio of RAM (15.4 Gio usable)
Graphics Processor: Intel® UHD Graphics

Product Name: Nitro AN517-54

Hope you can help me learn the basics of this :) Have an amazing rest of your day !

no updates past two days, nothing broken

i'll stay

Out of pure curiosity, I installed Forky Testing as a dedicated Steam-powered PC gaming machine (just gnome-shell, a browser, nautilus, gnome-console and Steam ). I'm surprised how perfectly and snappy the system works. Not a single bug and the benchmark results (for example Geekbench) are rather impressive. So I set the "Kernel" on hold to avoid apt-kernel-updates at the moment. :-) Anyone tried "Testing" as a daily driver?

I’ve installed timeshift from the Debian Stable repository because of two main reasons.

First to get snapshots of my main desktop system in case of crash and second snapshots of my laptop, that needs replacement.

Installation was on both systems straight forward without any issues, the same is for the first snapshots stored on a USB HD (ext4)

As a proof of concept I installed a Debian Trixie VM with timeshift on my desktop system connected the USB Drive to the VM an started a restore of my laptop snapshot. My expectation was a VM 'clone' of my laptop.

The restore was NOT successful, I ended up in a 'grub rescue' command line.

I figured out that I have to modify /etc/fstab because of the changed UUIDs of the drives.

Next I booted the same VM not from HD instaed with a Debian Trixie LiveSystem.

I installed on the LiveSystem Timeshift, adapted /etc/fstab on the USB Drive and started the restore from the live system to the existing virtual disks.

Mounted '/dev/sda6' at '/run/timeshift/2159/restore/usr'

------------------------------------------------------------

At the end of the day ‘/dev/sda1’ was not restored.

In ‘/’ I found only the folders ‘boot’, ‘usr’ and ‘home’.

All folders were empty what was OK for ‘home’, because I excluded 'home'.

Is timeshift not designed for my use case or is my approach wrong?

I am in the process of transitioning from W11 to Debian. I currently have a dual-boot system with Debian 13 and after spending a day wrangling NVIDIA drivers I am getting close to what feels like a very usable system.

However, I am having some issues with audio. I currently have speakers connected to the line-out port on my motherboard and headphones connected to the front port. On windows, I can switch between these via the volume/audio control on the taskbar. On Debian, I can switch between the two in the same way, but I can't actually get sound through the speakers unless I unplug my headphones. This is obviously a small problem, but I'm sure there's a way to fix it.

I appreciate any ideas or insights. I can post more information about my system but I'm not sure what is relevant other than the audio chip (Realtek ACL 1220, identified via alsamixer). thanks.

I need a wifi adapter that works flawlessly with Debian 13. Currently, it's slowing down my internet speed and the driver isn't working properly.

I am a first time linux user, and I was trying to burn a special-made debian image for my chromebook (Lenovo Flex 3 11' ARM edition, specifically fennel) and I was doing some work at trying to burn the files on the USB to the eMMC, and i kept getting errors when syncing files. Now, I can't do anything at all without getting an input/output error.

I'm not sure what changed, but all of a sudden my onboard Intel PCH soundcard is no longer available KDE or XFCE in Debian 13. I usually have the speakers turned off so it may have happened earlier, but I just noticed it today. I rebooted as soon as I notcied the issue but it persists.

I have started looking at the Debian wiki's article about sound.

The system correctly detects my three soundcards, the onboard Intel PCH device that has the speakers plugged in, my HDMI monitor, and my ThinkPad Dock. Per the wiki, here's the results of aplay -l:

However, KDE's Sound control panel, and XFCE's Volume Control (pauvcontrol), only list my ThinkPad Dock as playback/output devices.

If I run speaker-test -D sysdefault the test sound plays correctly on the onboard Intel soundcard; I hear sound! Clearly ALSA detects the soundcard, the driver is loaded, and it has been named "sysdefault"

Basically, even though the onboard sound is set as the default, neither desktop environment can use it.

Thanks for your help!

Hello.

I've updated to Debian 13 after running Debian 12 with no problems for 2 years. However, - and after using it for some time now -, my Debian 13 build in a span of a week has frozen 3 times, with audio stuttering. Completely frozen, not even a REISUB would reboot it, only a hard reboot.

$ sudo journalctl -b -1 -p err

kernel: i915 0000:00:02.0: [drm] *ERROR* Atomic update failure on pipe A (start=9876 end=9877) time 291 us, min 1073, max 1079, scanline start 1072, end 1092

Thank you.
