Linux Articles

• /dev/null: Permission denied on Alpine Linux One of my Alpine Linux VMs broke during an upgrade and started throwing errors about the permissions on /dev/null. Just fixing the permissions didn’t persist across reboots, but resetting the device manager did.

• Add a Gemini filetype to Gnome You might need to create a gemini.xml file and/or a .desktop file for your favorite Gemini clients. Here’s how and where to put them.
• Adding External S3 Storage on Nextcloud Using OCC It’s easier to add a storage folder for all users or for your own user via the GUI. But it is possible to create a folder for a specific user using the commandline tool.
• Airport Extreme vs. Linux (Obsolete) Broadcom refused to release drivers or specs for the chipset, so for years no one could even write their own.
• Apache, mod_ssl, and syntax errors in krb5.h (Obsolete) Syntax errors in krb5.h usually mean your Linux distro put Kerberos somewhere Apache isn’t expecting to find it.

• Double Lock Screen (Obsolete) Usually multiple desktops on Linux will stay out of each others’ way when they aren’t running. Not always.

• Firefox Thinks It’s Running an Older Version Than Last Time (But Isn’t!) Look for the compatibility.ini file in your Firefox profile, and delete the LastVersion line.
• Fix for “Among Us” not joining games on Linux Change your server region and change it back. No, it doesn’t make sense to me either. But at least it works.
• Fixing a Blank Article Pane in NewsFlash There’s a bug in WebKit that can prevent articles from displaying in NewsFlash, but there’s a workaround.
• Fixing Flash in Fedora Core 5 (Obsolete) Flash hard-codes the paths where it looks for fonts, instead of letting the X server tell it where to look.
• Fixing Twhirl (Obsolete) Just delete the entire ~/.appdata/Adobe/AIR/ELS/ folder and start from the ground up.
• Geary With Gmail, (Mostly) Without GNOME Install GNOME, add Gmail to your online accounts, then uninstall the rest of GNOME. But keep gnome-online-accounts!

• How Many Bits of Pi? Apparently all Raspberry Pi CPUs show up the same in the Linux kernel, so you have to look at the actual hardware to verify what processor you’re running on and whether it’s 32 or 64-bit.

• NVIDIA on Fedora 27: Bad Resolution and Painful Mouse Lag (Fixed) (Obsolete) As of 2017, Wayland didn’t work with the binary NVIDIA drivers, and the system would lag painfully. If you tell GDM not to use Wayland, it will fall back to the older display system.

• Setting up a Wireless Network on Linux 2.6: Ralink 3062 and Network Manager (Obsolete) Wifi on Linux can still be a pain to get working. Here’s how I set up a Zonet ZEW1642 on Fedora 13 using the Ralink 3062 drivers.
