 +==== 2018-09-02: Wifi firmware ====
 +By now there is a new [[http://ftp.us.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-atheros_20180518-1_all.deb|firmware package]] available from Debian, no more manual intervention is needed.
 +
 +==== 2018-02-20: Wifi disconnects solved ====
 +If you depend on Wifi for your connectivity and the Wifi disconnects all the time it can get really irritating.
 +After 3 days of intense searching I finally came across [[https://bbs.archlinux.org/viewtopic.php?id=229808|this post]] in the Arch Linux forums which describes exactly what to do so the disconnects finally stop. Ironically again Arch, maybe I should try that distribution for a change ;-)
 +
 +All in all I am still super happy with the XPS 13, great performance, great screen, great battery life. After solving the disconnects I can easily live with software rendering (for the time being) and I think even the Wifi power settings can be turned on again.
 +
 +Just to summarize the steps to get the disconnects solved:
 +
 +  * Download the latest Atheros ath10k firmware from https://codeload.github.com/kvalo/ath10k-firmware/zip/master
 +  * Make a backup of ''/lib/firmware/ath10k/QCA6174'' and delete the whole directory.
 +  * Unpack the downloaded ZIP file and place the QCA6174 directory in ''/lib/firmware/ath10k/''
 +  * Rename the latest firmware-X.bin files to remove the _WLAN* part.
 +  * Place the latest (highest version) firmware-4.bin and firmware-6.bin files directly in ''/lib/firmware/ath10k/'' (I used softlinks).
 +  * Reboot.
 +  * Check with ''lshw -c Network'' if the latest firmware is loaded.
 +
 +As Buster is still young I assume this will be long solved until it will be released.
 +
 +==== 2018-02-17: New challenge, XPS 13 ====
 +I got myself a new challenge: a brand new Dell XPS 13 9370 (2018 model) Developer Edition (non-touch). I really love this notebook, thus far I have not found one single point of criticism (I am not a webcam user ;-)).
 +
 +It comes pre-installed with Ubuntu and even after just booting it and using it for about 10 minutes I remembered why I don't like Ubuntu. So I quickly prepared a Debian Stretch installer stick with non-free firmware. The notebook is very thin and has no USB A ports anymore, let alone a RJ45 connector for LAN. So to install you depend on Wifi and for that the non-free firmware is really needed.
 +
 +However, somehow the Stretch installer didn't like the firmware, not even the updated one. It was looking for a 3.0/firmware-5.bin whereas there are only 3.0/firmware-4.bin and 3.0/firmware-6.bin files available. And because I wanted to start using this great piece of hardware as soon as possible I became lazy and just used the Buster installer which works fine.
 +
 +Points of attention so far (the rest is working perfectly):
 +  * The Wifi randomly disconnects. I had to disable power management for the Wifi card, a description of that will follow later on this site.
 +  * I am running KDE and using the compositor in hardware rendering mode (for e.g. the desktop cube) makes the screen become flickery after a while, the contents don't get redrawn. Switching to software rendering (no more cube) solves this problem and switching from the default OpenGL 2.0 to 3.1 makes it less likely to happen. I hope a future kernel module for the graphics will solve this problem.
 +  * The keyboard backlight turns off after just 3 seconds even though the setting is at 10 seconds. I will have to research this further (low prio).
 +
 +As said, everything else works fine and I am really happy. Ironically, the [[https://www.archlinux.org/|Arch Linux]] Wiki pages for the [[https://wiki.archlinux.org/index.php/Dell_XPS_13_(9360)|9360]] and [[https://wiki.archlinux.org/index.php/Dell_XPS_13_(9370)|9370]] were more helpful than the [[https://wiki.debian.org/InstallingDebianOn/Dell/Dell%20XPS%2013|Debian Wiki pages]] ;-)
 +As soon as I solved my problems I might make an account and edit the Debian Wiki page for the 9370.
 +
 +Updates on this notebook and Debian will surely follow!
