google-chrome-unstable在gnome wayland及 gnome on x.org顯示有問題，轉kde-plasma

好像是adduser的問題？

雖然是blink layout (rendering) engine but 刻意模仿firefox，例如new private windows是shift alt p 而不是google-chrome的shift alt n

我都沒留意重複裝了好多個fx，2個waterfox，fx night x3，firefox-esr，共6個，看places.sqlite meganess / muchness
places.sqlite應該是用了lightweight的mysql / Maria's database，bookmarks檢索資料量太大了

這才發現這jb會set dark theme on falkon，沒仔細看她帖子。怎麼她不用nightly，用fx esr extended support release，stable repository的packaged softwares都是36個月前的老舊套件

她推介的floorp死活裝不上，要麼flatpak，要麼自己compile，太麻煩了，falkon apt-get install falkon裝上了，dark theme搞了我兩三天
首先要裝
https://store.kde.org/browse?cat=571&ord=latest
https://store.kde.org/p/1980818
這玩意是kde的，gnome用web (epiphany-browser)，kde本來用khtml的konqueror和rekonq，現在轉qtblink的falkon，falkon基本上是模仿firefox (netscape navigator，ms-explorer的對手)
qtwebengine實際是qt版的blink，前身是webcore<webkit<khtml，源頭是kde的konqueror

falkon的adblock比較差，總體的體驗和chrome及fx差不多，大概是用qt toolbox寫blink，模仿firefox？
debian stable套件庫的套件太老舊了，unstable (sid) 進入testing最後進入stable，要36個月（3年）
以前用過debian sid及firefox，版本確實很新。當然我現在用的firefox nightly更新了，比stable release早兩個版本
https://wiki.debian.org/DebianEdu/roadmap
The goal for the DebianEdu project is to release Skolelinux at the same time as Debian. In general Debian is released every 18-24 month with security updates over a period of about 36 months after the release. Our experience is that the schools don't have the manpower to upgrade every year. A lifespan of 2-3 years is more suited for the system admins with scarce resources.

kde-plasma on x.org不知為啥，cpu佔用率很高，還是轉回gnome on x
wayland無法用xrandr調節亮度，所以沒法用wayland，而且wayland bugs很多

然後想回到debian，發現device mapper阻止我boot into debian，早上試試crypsetup luksClose

居然是 /etc/fstab 的問題，難怪之前fedora / debian dual boot，debian無法啟動，update-grub / update-grub2都不行，一直以為是fedora + btrfs的問題

apt .debs dependency hell，每次kde plasma升版本都卸載我所有des & dms
