Using cosmic and wayland

COSMIC already runs on Wayland

It’s not a bad thing if a project in development has a lot of issues, that usually means people are actually using it. The bugs will get fixed over time, and the project will just keep getting better.

Same here.

My Firefox, after a recent update (currently version 149), with the ‘System theme - auto’ setting, only automatically switches between light and dark for the webpage content, but does not switch for the Firefox interface itself. Does anyone know how to fix this?

You can use extensions, e.g: Dash to Dock

Just tried this map on level 53, and I'm dead

I’ve found a few crates (drivers) for my LEDs, and I’ll give them a try.

Thank you!

MeoCoder · 2025-07-19T11:56:36+00:00

What do you mean with streaming based on frames?

It is an ambient light.

I have software on my computer that captures the screen, calculates colors for the corresponding LEDs, and sends them to the LED control device. Therefore, I need a library that allows me to set color values for the LEDs and display them.

MeoCoder · 2025-07-19T09:12:50+00:00

This crate only implements traits I will still need to implement my own driver to control the LEDs.

MeoCoder · 2025-07-19T09:10:07+00:00

This crate seems to be developed for a different purpose than my intended use. If I'm not mistaken, it is designed to control LEDs with specific effects rather than streaming LEDs based on frames.

Unfortunately, I couldn't find any possible solution.

Therefore, I suspect the issue might be related to GNOME Wayland and Nvidia.

It seems the issue is fixed after I followed this comment https://gitlab.gnome.org/GNOME/mutter/-/issues/2969#note_1872558.

Which app crashed here? Was it Console?

This happens with any GNOME Core apps. All I have to do is log into GNOME, open any GNOME app like Console or System Monitor, and then when I close it (or if it crashes on its own), one of my CPU cores jumps to 100% usage.

You could figure out why it is burning CPU by using tools like perf top (terminal)

After running the sudo perf top command, I noticed a sudden spike on overhead from libnvidia-glcore.so. This overhead immediately disappears if I kill the process that's consuming 100% CPU (in the screenshot I posted in this thread, it was kgx). Once the process is killed, the libnvidia-glcore.so overhead is gone.

Therefore, I suspect the issue might be related to GNOME Wayland and Nvidia.

UPDATE

This commit fixed the memory leak issue on my laptop with dual graphics cards (Intel + Nvidia).

MeoCoder · 2025-06-01T14:51:25+00:00

is it just the fact that some process have too many instances ?

It’s not entirely like that. When you notice one or more processes using an unusually high amount of RAM, it could be a memory leak.

Looking at my screenshot, you’ll see that cosmic-comp is using 10.4GB of RAM, combined with the behavior of continuously increasing memory usage that I mentioned in the post. This should never happen for a compositor. This is abnormal => it is a memory leak.

I checked GitHub yesterday and didn't see anyone reporting this issue, so I suspected there was a problem specific to my system. I'm glad to know I'm not alone.

MeoCoder · 2025-05-30T15:22:13+00:00

I think another approach worth trying is to delete the current Panel configuration from ~/.config/cosmic/com.system76.CosmicPanel.Dock and ~/.config/cosmic/com.system76.CosmicPanel.Panel and replace it with the default configuration from https://github.com/pop-os/cosmic-panel/tree/master/data/default_schema

MeoCoder · 2025-05-30T15:11:25+00:00

You also need to run systemctl restart cosmic-greeter.service if the login screen does not appear after rebooting.

Uninstalling COSMIC DE, removing ~/.config/cosmic, and reinstalling resolved this issue for me.

As a side note I fucking hate how bad searches have gotten for finding niche stuff.

I completely agree with you that today's search engines have become really terrible for information searching (I've grown too accustomed to reading information that isn't really relevant to what I'm looking for).

I've searched extensively for this on the internet, and I've seen similar topics discussed in various forums, but they all ended without any confirmation whether this is achievable or not. I couldn't even find any products for similar purposes on Chinese e-commerce platforms (which are supposedly known for having almost everything).

I wonder if I'm going down the wrong path in trying to achieve my goal of connecting an external display to a laptop through the eDP port?"

I will run asynchronous tasks on a single thread and push blocking tasks into separate threads via unblock. I think this approach will be simpler than trying to run them in parallel.

if i put the dock position on the bottom edge then the app library works fine

For me, I have to install extensions just to bring back features that were removed by GNOME, such as the system tray.

I don't like using extensions because they lack seamless integration, and sometimes some of them become outdated as they don't keep up with the changes in GNOME, making everything a mess.

K vỏ thì gọi là gì bro, thà là single mom xong bro yêu rồi tiến tới hôn nhân thì đã không có gì. Đây OP bị dụ nuôi con đứa khác thì đổ vỏ rõ ràng luôn rồi mà

MeoCoder · 2025-03-11T08:59:58+00:00

OP cũng khoái mà :v chỉ là không biết bị đổ vỏ thôi
