Now to make it all RGB and shit 👾

Finally a distro has me tempted into considering moving from Arch which I've been using for almost a decade (kudos to the CachyOS devs on a job well done!).

But one of the things I love about Arch is that I choose what is and isn't installed and after my spouse installed Cachy (also previously on Arch) I can see a number of apps come pre-installed (like Meld).

Is there a list somewhere of what CachyOS installs by default so that I can uninstall it post-install? Or is there a minimal install ISO somewhere that I'm missing that just installs the Cachy 'tweaks' and Cachy-specific apps (like Hello) + a DE?

I have considered converting my Arch install to Cachy but since this install is 3+ years old now, it would be more difficult to find and get rid of all the tweaks I've made here and there than just start a fresh CachyOS install and remove unwanted packages.

EDIT: Here is the answer: https://github.com/CachyOS/cachyos-calamares/blob/cachyos-systemd-qt6/src/modules/netinstall/netinstall.yaml

SOLVED: BananaTrifleViolin's post contains the solution.

Flatseal won't start by itself anymore, which is a known issue. I got it running by running

GSK_RENDERER=gl com.github.tchx84.Flatseal

and inspired by a response in the above linked issue, I wanted to add GSK_RENDERER=gl as a variable in Flatseal so I could open it without having to manually run this in the terminal.

However, I seem to have screwed that up, and written GSK_RENDERER=ng instead, because the application still won't run, and now I get the following output anytime I try to open it by the method above:

(com.github.tchx84.Flatseal:2): Gsk-WARNING **: 22:09:54.997: Unrecognized renderer "ng". Try GSK_RENDERER=help
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:782: FINISHME: support YUV colorspace with DRM format modifiers
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:814: FINISHME: support more multi-planar formats with DRM modifiers
Gdk-Message: 22:09:55.406: Error 71 (Protocol error) dispatching to Wayland display.

However, I can't for the life of me seem to correct this. I've tried running the above command again, I've tried overriding it with flatpak:

flatpak override --env=GSK_RENDERER=gl com.github.tchx84.Flatseal

(which yielded a "permission denied", and nothing happening after running with sudo)

I've reinstalled the applications several times, including removing the config files from ~/.var/app/com.github.tchx84.Flatseal and checked that /var/app/ does not contain any config files.

I just want to reset the user input changes I made to this flatpak and start over, but I'm getting no where...

Is there anyway to pass terminal colors through a pipe?

As a simple example, ls -l --color=always | grep ii.

When you just run the ls -l --color=always part alone, you get the filenames color coded. But adding grep ii removes the color coding and just has the grep match highlighting.

Screenshot of both examples:

In the above example I would want ii.mp3 and ii.png filenames to retain the cyan and magenta highlighting, respectively. With or without the grep match highlighting.

Question is not specific to ls or grep.

If this is possible, is there a correct term/name for it? I am unable to locate anything.

That's pretty much it, after several months, maybe even a year of wanting to take the leap, a couple days ago I finally did it. I just wanted to share this cuz I think it's an absolute win, and I guess just see if anyone has any general advice to keep in mind during the process. I ended up choosing Fedora, right now I'm dual booting while I'm still in the process of finding software alternatives and getting everything set up, but trying to minimize my use of windows as much as possible, and so far I've been loving it. I love this community and I just wanted to thank everyone that has given any advice or suggestions in the past, i'm really excited about this and grateful that I could get to this point.

I can't search in discover for any of the KDE software like kmail or KDE partition manager. On the apps.kde.org website when I click the install on Linux button it pulls up discover. But it says "Could not open app stream://org.kde.whatever because it was not found in any available software repositories.".

I have been googling for awhile and can't figure out what repository I need or how to add it. If any one could help I would appreciate it. Thanks.

I have the following kernels installed:

• linux-zen (Zen)
• linux-rt (RealTime)
• linux-hardened (Security Hardened)
• linux-lts (Long Term Support)
• linux-tr-lts (Realtime LTS)

When I boot up, I try the different kernels from time to time just to see if anything interesting happens. It never does.

My question: How do I actually physically notice the difference between these kernels? If I use RT, does Firefox spawn quicker (in my testing, no, not really)?

What are some use cases when I can really see the difference in these kernels?

Using latest fedora 41 with Plasma Mobile, I can't get Bluetooth to work. Nothing shows up running bluetoothctl list. It's an intel wireless 7265, which shows up as a network controller under lspci, but the bluetooth part doesnt. hciconfig returns nothing.

Steps I've taken:

sudo modprobe bluetooth

sudo dnf install bluez bluez-utils

sudo systemctl start bluetooth

I'm having deja vu where I followed all these steps before, but somehow I'm stuck here. Thank you for any help.

so my Fedora installation was upgraded in place from 35 onward, survived three SSD upgrades (all glory to btrfs send | receive), got switched to systemd-boot, then from Gnome to Plasma, so there's some junk hanging about.

one of those is my flatpak setup that's system-wide, as was the style at the time, instead of the current user-level. although everything works, there are enough irritants (like forcing crappy electron apps to use wayland) that the old way is just a chore now. so, here's my brief write-up on how I made the switch.

flatpak --user remote-add --if-not-exists flathub https://flathub.org/repo  
/flathub.flatpakrepo

flatpak list --system --columns=application > system_flatpaks

edit the list by removing various org.kde., org.gtk., org.freedesktop., etc. runtimes and save it as e.g. flatpak_apps. otherwise, the following install and remove processes will ask tons of questions as to versions and nobody got time for that; the unused runtimes will be autoremoved later.

flatpak install --user $(cat flatpak_apps)

after it's done, time to pull the dependencies; no idea why they don't get pulled in the first place, when installing? anyhoo:

flatpak --user upgrade

will pull everything that's needed. thanks to the glory of btrfs deduping, this won't take up any additional space as it's already on the disk. to remove the system apps:

flatpak remove --system $(cat flatpak_apps)

after it's done, the runtimes:

flatpak remove --system --unused

and finally list all the system repos and remove them:

flatpak remotes --system

flatpak remote-del --system {flathub,flathub-beta,fedora-testing}

all app data remains safe and untouched in ~/.var/app, everything works as before and no reboots necessary. from this point forward, it's not neccessary to include the --user switch.

bonus content: if you haven't set up flatpak autoupdate, fix that post-haste.

I've got an x86 tablet, and I don't want to run Windows or Android, so I have always been left with the option of Linux with GNOME. GNOME is a solid DE, but despite the design language, it is nowhere near ready for touchscreens. Depending on the distro, it was either severely outdated or just generally buggy, particularly with the onscreen keyboard. This lead my to completely abandon my tablet for a while, but today I had an arbitrary though that I should try out KDE Plasma Mobile. Low and behold, it was exactly what I needed for my tablet.

I expected it to be a bit buggy, because I had tried out KDE Bigscreen and this seemed like the mobile equivalent of bigscreen, a fork that is half-baked and still has lots of work to do before it's worth daily driving. Imagine my shock when I booted the Fedora liveUSB and everything felt incredibly fluent and polished. I knew about 15 seconds in that I was switching. The navigation feels like an Android tablet, which I see as a positive, and the keyboard is just so much larger and more responsive. The GNOME default OSK is hardly usable because it's letters are so small, so this was a relief being able to type with no need for checking that I'm writing correctly every few characters. The next thing I noted is how polished it feels even for large screens(I have a 12 inch tablet). The gestures work on the whole screen, and this makes it feel effortless to navigate around. The final thing I want to touch on before I stop glazing is the really good performance. I have a very old tablet, about 10 years old, and the performance felt like it was brand new.

Thanks for reading my glazing exhortation, and if you have a tablet, I couldn't recommend Plasma Mobile more.

P.S. does anyone know where KDE connect is?

A Qnap NAS has a drive with some bad sectors, I want to RMA it, but before just want to figure out how to prepare a drive? It's part of a raid 5 setup of 4 drives unencrypted. So I want to remove it and wipe it. Got a Linux machine I can use, but never done this before.

What are common Linux tools to do that sensibly?

Let's say I want to enforce certain settings, such as the use of a proxy in network settings for certain users.

Isn't this easily bypassable by for example by installing TOR browser or using a VPN app in the user space?

How does system mangers can be sure users will only use the system as planned by the sysadmin? I'm especially interested in network settings, but in general I would be interested to know more about this/be pointed towards the right direction.

Thank you!

Hello :)

There isn't any community about note taking where I could post my question and no this is not a "What's the best note taking app" question...

I'm getting tired of maintaining my Obsidian vaults... Somehow I'm fighting to get it right and obsidian seems to fight back. I've got 4 vaults of the same subject and I always end to make a mess out of it and make a fresh one... Also my notes a scattered in all direction and the more my knowledge base grows the less I seem to be able to find something...

This is probably a me problem rather than Obsidian issue. The way I'm taking notes are not compatible with Obsidian. IMO Obsidian's defaults configuration are bad and visually not appealing. Sure customization in Obsidian is "endless" but digging in the HTML code to change the style or adding plugins to somehow get something visually appealing seems more like a chore than actually taking notes.

Here I'm again roaming the web for a Note taking app the could fit my needs and after trying a lot of different apps (please don't suggest the already well known apps... I have probably already tried it...) I couldn't find something that fits my workflow.

The only one that looked great and simple was osmosnote but it isn't maintained anymore. There's also dendron but it's in maintenance mode. So there goes the only ones that looked promising from my perspective.

After giving it more thoughts, I was looking for something that could:

• Keep my scripts updated
• Simple markdown text
• No database
• Local first
• Open source
• If webapp self-hostable
• Back-linking
• Keep track of changes

Except for back-linking, a self-hosted Forgejo with git seems to fit all my needs, however I'm not sure if this is the right tool and I'm scared that in the long run I will mess it up the same way I did with Obsidian.

Does anyone here has some experience and is taking notes that way? I'm really curious on your experience and maybe your thoughts if it's feasible ? Practical ?

Please don't suggest Org.mode or Emacs ! They look very cool and very promising but they are WAY to much overkill ! And they also implement a totally new way of taking notes... Relearning on how to take notes will probably give me the last hit on abandoning to document anything !

Thank you for any helpful input !
