In my earlier post on Complete rotation support for the Adafruit PiTFT 2.8″ capacitive touchscreen display I described that support for the touchscreen has landed in the mainline kernel in form of the ft6236 driver. I also described that my test program would work correctly now.
Complete rotation support for the Adafruit PiTFT 2.8″ capacitive touchscreen display
In my previous post, I introduced the PiTFT 2.8″ capacitive touchscreen display and showed some test code. If you played around with that, you might have noticed that with the default /boot/config.txt setting of rotate=90 the display is a landscape mode.
Getting started with the Raspberry Pi 2 and a Adafruit PiTFT 2.8″ capacitive touchscreen display
“We live in an age when unnecessary things are our only necessities” (Oscar Wilde, “The Picture of Dorian Gray”) Like many others, I bought another Raspberry Pi 2 to play around with, together with an Adafruit 2.8″ PiTFT capacitive touchscreen (note that Adafruit has various variants of displays that differ only in details such as… Continue reading Getting started with the Raspberry Pi 2 and a Adafruit PiTFT 2.8″ capacitive touchscreen display
Workaround for broken O2 Micro SD card reader support since Linux kernel version 4.1.8
On my Dell Latitude E7450 notebook I regularly update to current versions of the Linux kernel. Along with such a Kernel update my notebook’s SD card reader could no longer be initialized properly:

Fixing wireless regulatory support (crda, wireless-regdb) on openSUSE Tumbleweed
On recent SUSE-based distributions such as openSUSE Tumbleweed (and potentially also 13.2), executing iw reg get to check your WiFi device’s regulatory setup will likely get you an output such as this: global country 00: DFS-UNSET (2402 – 2472 @ 40), (N/A, 20), (N/A) (2457 – 2482 @ 40), (N/A, 20), (N/A), NO-IR (2474 -… Continue reading Fixing wireless regulatory support (crda, wireless-regdb) on openSUSE Tumbleweed
Correcting the soundcard order with onboard sound and HDMI output
Like many current devices with HDMI output, my Latitude E7450 offers multiple sound cards but configures the HDMI output as sound card 0 (the default). And xfce’s default sound mixer doesn’t offer switching the default output… To correct the soundcard order, add this to your /etc/modprobe.d/50-sound.conf (valid for openSUSE 13.2, probably other distros as well):… Continue reading Correcting the soundcard order with onboard sound and HDMI output
