Here is another spotlight of bookmarks I have come across the last couple of days. This time I am trying to roughly organize them a little bit, trying to make them easier to skim.

Display KeepassXC (aka QT5 apps) properly on HiDPI with fractional scaling

Tue, 02 Jan 2024 21:48:45 +0000

I recently received my 13 inch Framwork AMD edition which runs nearly flawlessly with Arch Linux. Its major drawback is the need for fractional scaling with the current display for a pleasant viewing experience. At the time of writing this is still an experimental feature for many desktop environments and UI frameworks. After enabling experimental fractional scaling support for GNOME 45.2 (on Wayland) I experienced some QT applications rendering badly, which especially bothered me with KeepassXC.

Lucky enough the solution was only one magical environment variable away: QT_QPA_PLATFORM=wayland. After setting it locally in my shell (set -x QT_QPA_PLATFORM wayland on fish) and running keepassxc to verify it is working, I added the variable to the corresponding .desktop file aswell. On Arch Linux, this starts with copying the system-wide KeepassXC .desktop file to the users local location (cp /usr/share/applications/org.keepassxc.KeePassXC.desktop ~/.local/share/applications/) to keep the changes after upgrades. After that, opening the local version and changing the Exec line to the following results in KeepassXC to start with crisp font rendering and UI: Exec=env QT_QPA_PLATFORM=wayland keepassxc %f.

Hope this helps ✌.

Reading and bookmarking a lot of stuff during each week, it occurred to me that I also might publish a collection of interesting links every once in a while to this blog.

So without further ado, here is my first collection:

Fixing "ERROR: device /dev/mapper/root not found"

Wed, 28 Jun 2023 08:02:36 +0000

This morning I booted my work laptop, only to be greeted by the error mentioned in the title. Being thrown into an emergency shell is not my prefered way to start my work day, but it is what it is and being a Linux user, I at least have tools ready to use to tackle such a problem.

It was not the first time that I encountered that problem. As far as I remember I always updated either the Linux kernel or some firmware package which then resulted in my encrypted drive not being mounted/found properly. Each time, recreating my inital ramdisk environment via mkinitcpio solved that issue. I assume that during the package update process something might have gone wrong recreating it (which normally happens automatically at least after updating the linux kernel). Yesterday was such a day where I updated the linux-firmware, linux-firmware-whence and amd-ucode packages before shutting down my computer to end my workday.

Since I was unable to use the emergency shell in any way (especially since no keyboard worked, neither the internal laptop one nor my USB one) I grabbed my ready-to-use arch linux install medium USB stick from my drawer and booted into it. I highly recommend having such an USB stick always ready (independent of the distribution in use) to be able to boot into your machine if the installed OS stops working. It is one of the superpowers people using Linux have – being able to access all their system by booting with another system.

Once booted into the installation medium, I was able to open my internal encrypted drive via cryptsetup and mount it and the boot partition. Using arch-chroot, which basically wraps chroot while ensuring some important functionality I was able to change into my local system installation.

Into my local system, there was only one thing left to do: Recreating my ramdisk environment on my boot partition. I achieved this by using mkinitcpio -P, which recreates all presets available. After waiting a few seconds for it to finish its job, I exited from the chroot, unmounted the boot and root partitions, rebooted my system and ta-da, it is booting properly!

Linux rocks!
