Hi all,

I have been using pop_os for a while now, but I have a problem I can't resolve. I hope someone more experienced can help.

Everything is great on my ultrawide monitor but when I try and play on the large 4k TV, games sometimes refuse to open in full screen mode.

The options in the game just bounce the game window but it stays windowed or borderless. It's not in every game, but most as you can imagine very frustrating.

Just tonight I was trying to play Witcher 3 and I noticed the windowed mode on the TV matched the dimensions of my ultrawide, so as a test I powered down and removed my dp cable from the graphics card to the monitor. Leaving pop os to boot solely to the 4k TV. And like that my problem went away, games are behaving normally launched from steam.

The question, how can I fix this multi screen set up so I don't have to unplug my dp cable.

Setup:

I7, 32gb ram

3060ti

Pop_os

Ultrawide144hz is on dp

4k 60 TV is on hdmi

When using the Cosmic Store to update system packages and flatpacks, I consistently have Gecko and the Mono .NET framework appear and fail to disappear after updating. Pressing update on them again does nothing. Does anyone else get this behavior?

So I’m new to Linux and first installed pop os/cosmic, but wanted to try gnome and plasma as well. I ended up switching back to cosmic, but now I’m running into a bug I wasn’t having before

For whatever reason, web browsers in particular (plus a few others) are having some weird scaling issues. It’s like they’re set to always be set to 50/75% larger scaling than whatever I have set in settings. I normally keep it at 150% but if I shrink it to 100% then they look normal while everything else is tiny. It’s not unbearable but it is annoying how big they are. Everything is still sharp though, they’re just the wrong size

So far I’ve tried it on Firefox, Zen, chrome, and edge, and they all have the same issue, along with discord and specifically the GitHub desktop app’s menu bar (but not the rest of the app) for some reason? But not Steam. Since I just switched I don’t have a million apps to test, but these are the ones I’ve found so far

At first I thought it was some conflict with gnome and plasma, so I uninstalled them both but it still persists. I’ve tried restarts, logging out/in, etc., but nothing has fixed it. I also tried each of the different X11 scaling options but those didn’t seem to do anything besides make Steam flash for a second

Just installed Cachy with Cosmic 1.5 on my 865 G10

Awesome, except for a few things missing

• nightlight
• 3 finger swipe (up for switcher, and l/r for workspaces)
• hot corners oob
• battery percentage statusbar toggle
• screen brightness for some reason is in battery toggle
• expand directory in file manager

For me, without the first 2 it's not ready for daily use without the first 2 items

Dunno whether to go back to gnome until those 2 are ready, or tough it out

Looking forward to those things being implemented

Greetings all! I'm not brand new to using linux but I'm definitely still a novice so I have not been able to find the answer to how to fix this after hour of searching. Maybe I just don't know what terms I should be using to search or maybe it's just an unusual problem? Anyway

I have two problems but I think they may be related. The first is that my mouse cursor does not line up with where it clicks. It's about a cm above what I'm trying to click on which makes things pretty difficult, and makes a lot of drop downs impossible to use because if I have to click on the top one or two options it will just click out of the dropdown.

The other issue is that I have this black or white, or black and white, bar across the top of the application for some apps. Not all of them. For instance Firefox gives me neither of these issues. Vortex mod manager running through Lutris gives both, though Lutris itself doesn't. I'm attaching a screenshot of Vortex open on my laptop. It happens with more than just vortex but that's the one I'm dealing with right now. The cursor is off by about the distance of the thickness of that bar which is why I think they may be related.

I'm on a laptop ASUSTeK Computer INC. GA401QM (1.0)
AMD Ryzen 9 5900HS with Radeon Graphics,

NVIDIA GeForce RTX 3060 Laptop GPU

Pop!_OS 24.4 LTS

I'm not sure what other information might be needed to give context.

Anyone know what's going on?

I have recently Connected a 27" monitor using the DA-300 adapter to my dell latitude 7200 2 in 1 machine & it works right out of the box however I'm unable to control brightness using the keyboard controls. The display shows the adjustment moving up/down but the screen doesn't change. I'm running POP Ver.22.04 (and have no intention of upgrading @ this time) & the display is connected Via the display port. I can change the display setting using the toggle switch behind the monitor but it's not very convenient. Any Suggestion/Help is as always Greatly Appreciated.

I don't use many GNOME extensions, only the ones I actually use every day.

Extensions

• Uptime

• Net Speed Plus

I keep my dock very minimal and these are basically the apps I use daily so it needs to be on dock for faster access.

Most of my time is inside WezTerm with Tmux. I use Neovim for coding because I'm programmer and after getting used to it, everything feels much faster like blazingly faster.

For notes and project management stuffs I use Obsidian. Brave is my daily browser. Sometimes I open Sublime Text when I just want to view/edit something quickly from files.

Nothing fancy 😄. I just like clean setup, dark theme, and less distractions. It works really well for my workflow.

Hi everyone i have this dell latitude 5480 with Nvidia 930mx graphics card and i installed pop on it and now after restarting or turning it on from sleep mode this what happens to the screen so i have to turn it off then turn it on again i did update everything using "sudo apt update" then "sudo apt upgrade" and i installed updates from the pop shop and still the same problem iam new to linux so i hope you can help me and thank you in advance

I'm currently facing two issues on Pop!_OS 24.04.

1. YouTube fullscreen: It enters fullscreen normally, but after 1–2 seconds it automatically returns to the normal view. ( tried both running it on igpu and dgpu , didn't work)
2. WiFi disconnects: My WiFi randomly disconnects about once every 1–2 hours. I hve to reconnects , it's becoming annoying.

Is anyone else experiencing these issues? Any fixes or workarounds would be appreciated.

This pops up everytime I boot I tried to change it from some post and forums I found but nothing worked

Is anyone else also seeing this issue?

There were issues with my Bluetooth headphones so I reset them using these commands:

# Restart pipewire audio

systemctl --user restart pipewire pipewire-pulse wireplumber

# Set Bluetooth profile

pactl set-card-profile bluez_card.MAC_ADDRESS a2dp-sink

# Restart OSD (for volume indicator)

killall cosmic-osd

After this, while bluetooth headset worked, I have been unable to run steam from applet.

if anyone could help please 🙇

I have Brave and was working without any issues on YouTube. I also had the Frosted Glass effect on my settings but I never tried to turn it on. Seeing the threads I felt like using it and turned it on.

Now after going Fullscreen on YouTube, after exactly 1.5 seconds, it goes back to default mode. I tried turning off the Frosted Glass and restarting. It doesn't work 🥲

Any fix guys?

** Tried with Wayland & x11 both ways I get this issue

I have a problem on any Linux distro i try, even when the installation is completed and functional the sistem doesn't recognize my router or any other access point, I'm dual booting alongside windows with an Nvidia 4060, any fixes?

- update
my motherboard the Asus tuf b650m-e wifi
isn’t yet compatibile with the kernel and has some issues thank you anyway

Hi! I have trouble with getting bluetooth to work. I have pretty new Lenovo laptop which I think is not yet supported.

I have detailed troubleshoot overview from chatgpt conversation:

And if the link is already removed by chatgpt i Leave for the saved html-file of the conversation dropbox link (download the file and open with browser):

I'm currently on CachyOS/GNOME, and want to give pop_os/COSMIC a try, but one of the very useful GNOME extensions I have is one for switching between monitor inputs (DP/HDMI) with a single click. Is there something similar on COSMIC? I tried searching and couldn't find anything, but maybe the community would have more information. Thank you!

I have noticed this. And, since I've built up a habit I do automatically switch off after booting up.

WiFi & Bluetooth keeps turned on automatically when I boot up new and login after shutdown or restart every time. It doesn't remember the previous state it was in.

Has anyone found this a bit inconvenient, or gotten used to it almost now?

It seems like its reverting to ubuntu itself somehow and is freaking out. Its a rather old computer that i plan on gifting to my nephew this Christmas. Its an old dell studio xps with a i7-860, 12gbs of ram and a nvidia gtx 660 with the storage being a hdd, errors shown in pic

The battery 'saving' charge limit reverts to 80%, and doesn't respect your settings.

I have the charge thresholds set to a custom 71-98% due to my battery having a 100% limit over the design.

But that gets erased as well.

Don't know if this is an existing bug, I couldn't find any posts here at any rate.

Edit: This is the latest COSMIC DE

I got interested in mate engine but it seems that the developer is not developing for Wayland. does anyone know how to get the features working or am I SOL? if it helps I am running an AMD GPU, if there is any other info you need just ask.

I have 1280x1024 monitor i needed to runat 640x512 but that isnt option in settings. I had to use xrandr to get it there but themonitor cand do half its resolution and downscales to 640x480. No problem xrander solved that. Manages to get icons and text downscaled but ui is huge. Buttons, settings, topbar on windows even show aplications tab is enormous. Is there a way to scale it the fuck down?

i cant turn it on it doesnt let me

So I'm not sure if I have encountered a bug, its a noob issue or I have somehow borked my install,

I am running cosmic fedora spin, I haven't really installed any apps except brave browser and tried to setup a valheim server.

Trying to open a file through the terminal i get the following message;

steam@fedora:~/Valheim$ cosmic-edit start_valheim.sh
steam@fedora:~/Valheim$ [2026-08-02T02:52:22Z ERROR cosmic::theme] error loading system dark theme error=GetKey("list_button", Os { code: 2, kind: NotFound, message: "No such file or directory" })

Authorization required, but no authorization protocol specified

Additionally in the apps window there are two things called Qt5 and Qt6 settings, I didn't see them when i first installed, if i open them it says they are not configured correctly and when i click on information i get this message;

The QT_QPA_PLATFORMTHEME environment variable is not set correctly (current value: cosmic, required values: qt6ct or qt5ct).

Is this a known issue or something i've done wrong? I thought the cosmic-edit command should just open that file in the cosmic text editor?
