For a long time, when using my computer (Arch linux), I would sometimes run into this problem. When trying to open an application in a new window, I'll be met by:

 undefined

    
Invalid MIT-MAGIC-COOKIE-1 key
cannot open display: :0


  

I've tried a lot of "solutions" without luck, but I've finally found a way to consistently reproduce the error. It happens everytime I connect to a new wifi.

I found this 9 year old post about the same problem, but it does not include a real solution or the cause of the problem.

I'll try asking it here, to see if anybody knows why it happens and how to solve it, and perhaps to help others with the same problem find the cause of this error. It is such a relief for me, knowing that it is caused by changing wifi.

In advance, thanks for the help/feedback :)

I'm having network issues on Arch Linux, particularly with Steam download speeds, which fluctuate and are slower than usual. Additionally, I've noticed that things sometimes take longer than normal to load but usually load up after refreshing which makes me think the issue is not specific to Steam.

Here’s what I’ve tried:

• Tested on a Windows laptop which showed normal speeds.
• Reinstalled my system using Bazzite, which resolved the issue and showed normal speeds.
• Reinstalled Arch Linux, but the problem returned.

Other Info:

• Installed Arch with Archinstall using NetworkManager
• I'm on a wired connection
• DNS set to my router, which uses Quad9 DNS
• Steam installed via Flatpak

Any troubleshooting ideas or suggestions would be greatly appreciated!

I want to hide the about tag in rEFInd. So, I did according to the info in config and website, which is to add a showtools line with no options.

And, nothing happens. I still see About, Shutdown, Reboot, Firmware tools in the rEFInd screen

 This is my rEFInd config containing showtools 👇

    
# Default is shell,memtest,gdisk,apple_recovery,windows_recovery,mok_tool,about,hidden_tags,shutdown,reboot,firmware,fwupdate
# To completely disable scanning for all tools, provide a showtools line
# with no options.
#
#showtools shell, bootorder, gdisk, memtest, mok_tool, apple_recovery, windows_recovery, about, hidden_tags, reboot, exit, firmware, fwupdate
showtools

  

Eventhough the previous showtools line is a just a comment, I removed it too. And still nothing happens.

Does anybody have any idea?

I only want Shutdown, Reboot.

SOLVED

It seems like a rEFInd problem in latest version.

What do I do, when my PC freezes?

Windows has ctrl+alt+del, does Linux Mint has something comparable? The only thing I know about is REISUB, but that borked my PC, so I am hesitant to use that again.

Are there any remaining alternatives to waiting and/or using the power button?

Edit: Thank you all for your insights and possible fixes. Crashes usually happened when I was running (cpu/ram?) heavy workload. Increasing swap space was not even on my radar, so I did that now. :) Hopefully Mint will run more stable now.

I installed lots of OSs on my PC. The mistake I did was not backing up my EFI partition beforehand.

Now I deleted all the OS except CachyOS (Arch) and Windows.

Now I want to tidy up my EFI partition. I want to delete everything (even rEFInd) except Windows and Default ones like OEM. (I am gonna reinstall CachyOS ) Can anybody please assist me?

I already deleted the obvious ones like ubuntu and fedora. Anything else?

I know this is not necessarily a linux question but anyways 😅

Solved

Before proceeding with any of the following, I STRONGLY suggest you to make a full backup of your ESP (efi) partition.

I deleted everything on boot folder, since I didn't need grub or any of those files ( after searching everything individually on internet)

I deleted refind folder, since I didn't need refind boot manag

I installed CachyOS with BTRFS, LUKS2 , REFIND.

After successful installation I'm not seeing any prompt for password nor the linux boot entry on refind.

Note: I didn't do any lvm or raid.

What should I do?

Solved

I just forgot to create a boot partition 😮‍💨

Let's say i made 10 snapshots on top of the base.

Now can i delete snap no. 5? Will the snaps after 5 will be affected?

Solved

Yes, one can delete consecutive snapshots. The data won't be deleted unless all snaps ( reference points ) get deleted.

Note: If you delete the original file and delete all the snapshots made when the file is still there, the file will get deleted permanently.

So, I am looking for any ideas, help or head(s) smarter than mine.

This is my main problem for some time now, easiest way to replicate this is to run anything proton related. After that, some apps just keep spitting this via dmesg:

How to install ProtonVPN in Arch Linux (CachyOS) ?

Should I follow https://wiki.archlinux.org/title/ProtonVPN ?

OR

from flathub https://flathub.org/apps/com.protonvpn.www ?

This flatpak has Unverified tag, but according to this, this flatpak is safe.

Which one should I follow ?

Asking this because I'm because I'm a bit lazy to configure OpenVPN and all that stuff. (pls don't kill me :)

Also do you think using VPN from flatpak is a good idea?

Solved

I just installed aur mentioned in the wiki and it worked just fine. Didn't need to install anything else in my case.

I want to copy (not move) my Timeshift Snapshots (Rsync) from my existing drive to another drive. Both drives are ext4. As far as I searched I am not able to find any viable results.

If not possible, just why?

TLDR

sudo rsync -az -H --delete --numeric-ids /path/to/timeshift path/to/destination/

  

Where,

-a : Archive mode (i.e. recurse into directories, and preserve symlinks, file permissions, file modification times, file group, file owner, device files & special files)

-z : Compress file data during the transfer

H : Preserve hard links (i.e. copy hard links as hard links)

--delete : Delete extraneous files from the receiving side (ones that aren't on the sending side), but only for the directories that are being synchronized i.e. keep exact replica of your

I can't change directory and file permissions which is in /mnt/ through elevated Nemo. But can change in /. Why?

Apparently, this happens due to Automount. Because when I mount manually, this problem doesn't occur.

I also changed /mnt/Storage to /media/user/Storage/ on auto mount, still the same problem occurs.

Include uid= and gid= as part of your mount options.

Pretty much the title. Maybe to add a bit of a backstory: Bazzite was awesome at first, all games ran on the first try!!

But then: I still haven't installed my vpn, let me quickly do that. Oh wait, there's no flatpak for my vpn, that's right.

Aight, lemme first install tlp and get these laptop fans under control. But wait, how? There's no flatpak. If I install it in distrobox, it has no effect, which kinda makes sense.

Whatever, lemme try auto-cpufreq. No flatpak, so distrobox it is. To no surprise, it fails. "System has not been booted with systems as init system."

Same with Goverlay. So then I just fell back into my chair and screamed: "How the hell do I install stuff on Bazzite to control my laptop?!"

I ran yay -Syu and everything went well but electron25 has taken over 10 hours to update. Is there anything I could have done to speed things up?

Solution: I checked AUR and other people were commenting about similar issues. I swapped out the package for the -bin version.

I wish to change the default Nautilus file dialog that Firefox uses, to Dolphin (my main file manager) but I cannot find any solution. Every single time I download an image, Nautilus is opened instead of Dolphin.

I tried adding GTK_USE_PORTAL=1 to my env variables, and It didn't work, then I tried changing mimetype and also did not work, I also tried modifying the xdg-portal (sorry if I'm wrong) to use xdg-desktop-portal-kde instead, but I cannot accomplish this since I didn't understand at all the Arch wiki and IIRC some files aren't exactly where the Arch wiki was pointing them.

As a last attempt, I open about:config in Firefox and search for widget.use-xdg-desktop-portal and set it to True, and still I keep having that old Nautilus as my file picker in Firefox, and this last thing usually worked well for me in Plasma.

Edit: I just restarted my pc and now randomly seems that Dolphin it's the file dialog for Firefox, I don't have a single clue how this happen.

Hello, everyone. Recently I finally decided to update my system, and right after the update ran into a problem: before update baobab showed ~22 GB avaliable space, and after the update it went down to around 8.

Here's some info, that might be relevant:

SOLVED: Installed GloriousEggroll custom Proton. For Talos, also had to set launch options (PROTON_ENABLE_NVAPI=1 PROTON_LOG=1 %command%) or else I'd just get a black screen. First runs of games take a bit to get loaded, but launch without issue on subsequent runs.

I'm a recent convert to Linux - currently running Mint 21.2. I don't have a huge Steam library and thankfully most of the handful of games I play have worked fine - Deep Rock, Lethal Company, Sea of Thieves, Elite Dangerous (although that one is through Epic, thanks Heroic Launcher).

Two others that I've tried so far - Astroneer and Talos Principle II - don't seem to want to get started. When I hit play on either of those in Steam, it just stalls at "Launching..." I can cancel the launching and it'll go back to the Play button, but at this point Steam won't launch anything else. When I try to exit steam, the main window closes but its icon is still in the system tray icons. At this point, I have to kill the steam tasks be
