I'm looking for such a device:

• 2-in-1 laptop, or at least a laptop with a touchscreen (optimally also with a stylus)
• 14 or 15 inch screen
• Good battery life (thus probably intel CPU/GPU) and lightweight
• Optimally not a thinkpad because I don't use the trackpoint and I prefer to tap the touchpad instead of clicking physical keys.

The candidates I'm currently interested in are lenovo yoga 7i 14/15 and asus zenbook 2-in-1s, but they all use OLED displays. For these devices is OLED a problem with linux? Mostly, does linux's software-only dimming make battery life worse? And are there ways to avoid burn-in risks? (I'm using wayland compositor niri). I heard that yoga 7i has IPS versions but they are not available in my region, and I'd like to avoid international shipping. And for this reason I would prefer to stick to mainstream brands like lenovo, dell, and asus.

On this laptop I'll mainly do note taking and coding with neovim (which is dark theme and shouldn't have much problem), video playing, video editing, running small LLM and image generation models (better have good GPU multithread performance), and writing latex documents (which has light backgrounds and is my main concern with OLED). Would OLED on linux be a viable option for daily driving for my case?

If OLED is a true concern, are there relatively new LCD 2-in-1 models with good linux support and battery life?

The internal microphone doesn't work on my Dell Inspiron 14 7440 running ubuntu, though it is recognized on windows and I remember it working before I reinstalled the ubuntu system. When I open sound settings, the app doesn't recognize the internal microphone:

I ran alsamixer (newest version) in the terminal and didn't see the internal microphone, this is what it looked like (this screenshot shows all devices listed in alsamixer):

I also looked at pavucontrol and the app shows the internal microphone as "unplugged":

How can I get the microphone working?

Update: I tried plugging in a headset and plugging it out. When I plugged it in 2 microphones showed up, one called "headset microphone" and the other just called "microphone", screenshot:

But when I unplugged the headset both microphones are gone, does it mean that my laptop recognizes its internal microphone when a headset is plugged in? Also when I switch to the one just called "microphone", speaking to the headset microphone doesn't make the bar move as much as patting the laptop, so the "microphone" should be the internal microphone.

I installed the newest ubuntu desktop on dell Inspiron 14 7440, and when I open a video (either mp4 or webm) with GNOME videos it looks like this in the image, showing horizontal bars.

Is this a graphics driver problem? I haven't installed any kind of driver after the ubuntu installation, and if it is a driver problem from where should I install the driver?

I'm planning to buy an Inspiron or XPS model and install Linux on it, and I'd like to run neural networks accelerated by its NPU. Are there available drivers for the NPU in these models that supports debian or ubuntu-based systems?

After installing Mac OS sonoma for a few weeks my mac quickly ran out of storage. I did a scan using cleanmymac and found this huge folder in /Library/Application Support/com.apple.idleassetsd/Customer/:

I opened the folder and found it full of high-quality landscape videos, which is probably used for screen savers. Would anything go wrong if I delete everything in the folder and use the old screen saver?

The main features I want are:

• Import PDFs and annotate them in the app’s native format (so that I’ll still be able to remove previous changes after I save and re-open it)
• Quickly add text boxes anywhere on the PDF
• Draw some basic shapes and lines with different colors (can either be notability-style “draw and hold to make shape” or just a classic “insert shapes” option from the toolbar)
• Have a page thumbnail option and can search text in the PDF file and quickly go there

I'm on Mac OS sonoma beta and I've been using the solar gradients wallpaper since it exists. But a few days ago white vertical bars appeared on the wallpaper. When I switched to another wallpaper and switched back the white bars disappear. Yesterday the same issue happened, but when I switch back to the solar gradients wallpaper, the vertical bars are still there. Although any other wallpaper doesn't show vertical bars, I really want the solar gradients wallpaper back, how do I fix this?

Bot link: https://poe.com/Anarchychess-bot

This bot is made to talk in anarchychess-style, which makes it great at generating memes and copypastas. It can also give humorous comments on chess gameplay (though it sometimes hallucinates).

I made it based on claude-instant because claude is better than ChatGPT at creative writing.

Some screenshots:

I just switched from firefox to librewolf and I imported the autofill passwords through a csv file, but autofill isn't working when I log into websites (the autofill option doesn't show up when I click into "enter password") and I have to manually copy the passwords from about:logins. How do I fix that?
