COSMIC Store is coming along quickly, though there is still a lot left to do. It loads nearly instantly, because it uses bitcode to cache appstream data in an optimized format. It uses very little memory compared to the Pop Shop. Searches can be performed live as they are done in parallel. Searching for "e" takes 5.5 ms on my desktop and returns 4601 results.

1. install virt-manager

2. create a vm pop-os

3. start the vm

4. sudo apt install cosmic-session

5. sudo nano /etc/gdm3/custom.conf

6. set "WaylandEnable=true"

7. reboot

8. at the log in screen, there is a small gear wheel on the bottom right side, choose “Pop on Wayland" (edit: if you want COSMIC DE to work too, see update below)

update:

there are some settings on the virt-manager to make COSMIC DE works.

if you don't need to run COSMIC DE, can ignore the following

• Display Spice : Type = Spice server, Listen type = none, uncheck password / opengl
• Video : use QXL (instead of default Virtio)

new step 8. at the log in screen, there is a small gear wheel on the bottom right side, choose “COSMIC"

To reproduce this, click Application (or Super + A), Hover over to the Firefox Icon, right click.

there are "New Window" "New private window" and "Open Profile manager"..

the last one wasn't here before the update. can i get rid of it?

Hello, for months I've had a problem on my #PopOS, on some apps, when I open a window for the first time after a start-up or after a sleep mode, the window closes automatically.

It's a bit random, where it always happens is with the "Files" application, it's very annoying.

Today we have the one of the 2 founders of System76 and current CEO of the company Carl Richell on the show to chat about the history of the company, how we got here and some of the cool stuff they've got in store.

I recently installed Pop on another device, everything is fine except for Pop Shop which seems to be missing apps that I already have installed through there on my main desktop.

I checked that I hadn't accidentally deleted/messed with the sources and they all look fine. These are common apps like Librewolf, Joplin and Standard Notes.

I know they can be installed through other methods like apt or appimage but am curious as to the possible reasons behind the discrepancy. What's more confusing is that I had a few attempts installing Pop (as recently as 10hrs ago) on this newer device and they appeared then!

I'm using the virt-manager to install Pop!_OS on a virtual machine from the latest ISO image (...38.iso) with QEMU for testing:

GRUB starts okay, running the tests. Then the QEMU window turns completely black and nothing changes for hours. This didn't happen with the previous ...36.iso of the image.

Any help is highly appreciated. Thank you!

note that, this issue has been around since ...37.iso

With today's repo-release PR #312, Pop!_OS is now building packages for 24.04 (Noble Numbat).

While this doesn't mean a release will happen any time soon, it does mean they are now beginning the process of testing and packaging for 24.04. In particular, they are now building many of the COSMIC DE components for 24.04 with this pull request.

The base Ubuntu 24.04 LTS shipping with Linux kernel 6.8 is anticipated for release on April 25th, 2024.

Today I saw someone once again trash System76 for rebranding Clevo machines and writing that off as some kind of deceptive business model. Ultimately, they're not "just rebranded Clevo...", but even if they were, the ignorant douchebag posting this misguided rant fails to acknowledge that EVERY SINGLE LAPTOP OEM does the same. Yes, HP, Dell, Lenovo - fucking all of them!

Sometimes when resuming from sleep, or when playing a fullscreen video, my screen will fill with white video blocks.

rebooting will fix the problem (until it appears again).

$ uname -r
6.6.6-76060606-generic

Similar to this: https://i.bke.ro/selif/artifacts.mp4 and https://www.youtube.com/watch?v=7Xt2e9Lt2gg

and issue: https://gitlab.freedesktop.org/drm/amd/-/issues/2735

One solution is to add amdgpu.sg_display=0

sudo kernelstub -a "amdgpu.sg_display=0"

It is fine when not put in full screen. When i put it in fullscreen mode, it shrinks to about 1/3 to 1/4 and moves to upper left corner. This happens only on a wayland session/

my laptop resolution is 2256x1504, while my monitor has standard 1920x1080. when I start Pop is always default 200% scale, even I changed it to 100% before. I have to manually set it to 100% scale on my laptop and monitor. But it would not sustain. When I unplug hdmi and reconnect, everything goes back to default. Is there any ways I can optimize this? thank you

Reviewing some of the latest updates with the cosmic terminal, files, and more.

COSMIC is a Wayland desktop environment for Linux that is written in Rust with Smithay and Iced. COSMIC applications are developed with the libcosmic platform toolkit, which is based on iced. They are cross-platform and supported on Windows, Mac, and Redox OS in addition to Linux.

As COSMIC nears its alpha release in Q1 of 2024, we have thus far developed a terminal, file manager, and text editor for our desktop environment within the last few months.

Everything worked fine until today, updated the system yesterday. Cursor works, I can start the reboot and such, but not app will open, no terminal command can be performed, and the shutdown doesn't finish after 30 minutes, meaning I have to perform a SysRq reboot to actually do something. Will check Discord and VSCode in a second, also try to apt update and post findings in an edit. Worst case I can wait for an update using dual-booted windows.

Edit: Apparently the problem fixed itself - none of the apps crashed, even when I went back to the previous settings. I've booted into Windows to write this post which might've helped (instead of breaking things the usual way), apt didn't do anything, but there were 2 runtime updates on Pop shop which I've installed prior to starting Firefox. Anyway, one of them can help if any of you are unfortunate enough to have the same problem.

Gaming on Linux is easier now than ever before. Though many PC games are still developed with Windows in mind, the emergence of Valve’s Proton and proceeding contributions from the open source community have made Linux gaming into a first-class experience.

Hi, I'm making this post today because I've been having some problems with Nvidia drivers with wayland. Looks like nvidia driver 535 was having some issues with Godot (flatpak), the error was something about Vulkan, anyway, it's not important now.

The versions 535 and 545 of the nvidia driver have been causing some problems on my machine while using wayland, so I'm making this tutorial for the folks that are encountering problems and wish to change their driver version to (hopefully) solve their bugs while waiting for the latest driver to be updated.

Let's get started.

DISCLAIMER: I am not responsible if you break your installation or if you damage your machine in any way.

1st step

First of all, I highly advise to install Timeshift. It's a neat program that will make a snapshot of your system configuration (depending on how you configure it) so you can roll back in time if something goes wrong. It saved my linux installation many times.

2nd step

If you wish to see your current driver version, open a terminal and type:

$ nvidia-smi

I advise to write the version down, or at least remember it.

3rd step

To view all the nvidia drivers you can install, open a terminal and execute:

$ ubuntu-drivers list

or

$ ubuntu-drivers devices

These 2 commands (you can use whatever you prefer) will tell you all the nvidia drivers that are available for installation.

To delete your current nvidia driver, open a terminal and execute:

$ sudo apt purge ~nnvidia

Then, you can install one of the nvidia drivers we have seen before, for example:

$ sudo apt install nvidia-driver-535-server

(If I understand correctly, the server drivers are no different from the normal drivers, other than the fact that they are supported for longer and they should in teory be more stable).

4th step

After your new driver is installed, you can reboot your machine, using the UI or the terminal by executing:

$ sudo reboot

5th step

If you want to use X11, you're done. If you want to use Wayland, you have to do some additional steps.

To enable wayland in pop-os, you first have to enable nvidia modeset if it's not already enabled.

To check if it's enabled, you can go inside /etc/modprobe.d/ and check if any of the files contains options nvidia_drm modeset=1. If you find nothing, you have to create the file yourself.

To do this, execute:

$ sudo nano /etc/modprobe.d/zz-nvidia-modeset.conf

The content of this file should be:

options nvidia_drm modeset=1

Then execute:

$ sudo update-initramfs -u

6th step

To be sure that there is nothing else blocking your machine from enabling wayland, execute:

sudo nano /usr/lib/udev/rules.d/61-gdm.rules

Inside this file there are some rules, some of which may stop your system from displaying the wayland option inside the little gear in the login screen.

Specifically, you have to check these lines:

LABEL="gdm_prefer_xorg"
#RUN+="/usr/libexec/gdm-runtime-config set daemon PreferredDisplayServer xorg"
GOTO="gdm_end"

LABEL="gdm_disable_wayland"
#RUN+="/usr/libexec/gdm-runtime-config set daemon WaylandEnable false"
GOTO="gdm_end"

LABEL="gdm_end"

Check that the lines starting with "run" are commented out.

7th step

We are almost done.

Execute in the terminal

$ sudo nano /etc/gdm3/custom.conf

Here you will find a line like this

# Uncoment the line below to force the login screen to use Xorg
# WaylandEnable=false

You can leave it as is, but if you can't see the wayland option in the login screen, you can come back and edit it like this:

# Uncoment the line below to force the login screen to use Xorg
WaylandEnable=true

8th step

You can reboot your machine, and when it boots back up, you should hopefully see the wayland option in the bottom-right gear in the login screen.

9th step

Don't forget to run:

$ flatpak update

To allow flatpak to install the new version of the nvidia driver for your flatpak software.

Final

I hope you found this tutorial useful. If you want you can suggest improvements, or edit and share it on other platforms if you want more people to see it.

Heyo,

i swapped to Pop!_os 2 days ago ( from linux mint, because i wanted some change and found pop_os ) and i like it!

I have just few points that i would like to share:

• That the displays scaling cant be changed per monitor untilthe activation of "Fractial Scaling" ( just as a beginner "weird" behaviour )

• You cant disable / make the "Active window" border smaller.

• You cant hide the top bar ( but thats acceptable as it hides itself if you are in full screen )

• Customizability/Lack of keybinds ( for example move active window to Screen 1,2,3 with Super + 1,2,3,4 )

• (The pop_store lags? sometimes if i search? idk if its just a known bug or if its something on my side?) )

But its still very good and it has some cool features and simple installation!

Thanks for the System76 devs for making such great OS!

LazPaint is a surprisingly good image editor.

I've looked around at many raster image editing apps for Linux, and I have mostly been disappointed.

• The Gimp is hard to use and has lagged behind major other platforms' banner image editors.
• Pinta is "ok" but has graphics glitches on my hardware (Intel).
• Inkscape is good but specializes in vector graphics, not raster images.
• Krita looks like it might be particularly good for artists using a tablet, but is mediocre for raster image tasks and has a complex interface.

I've also tried various "simple" apps such as KolourPaint [1] and Drawing [2], but these are generally more like "MS Paint" and have limited capabilities when importing images for various editing tasks.

LazPaint has all of the major features you would expect, without an over-complicated UI--selection, layers, gradients, filters, shapes, opacity, many file formats etc.. However, it is not wrapped in a Flatpak, so you need to download the "deb" file and install with Eddy (or the CLI):

https://github.com/bgrabitmap/lazpaint/releases/tag/v7.2.2

As an aside, I recently also discovered Pixelitor, and I think it's another one to keep an eye one. The author seems to be making some great progress lately (most recent release in September 2023).
