AcherC7 5Ghz wifi problems; and my X390 ethernet speed fuckup.

Arher C7 5Ghz problems

好耐之前刷完Openwrt之後，config完一輪keep完用都冇乜事(雖然冇事但我都想換)
今朝搞咗陣個network試嘢改咗啲config之後
個5Ghz ac wifi就跪低咗 (Wireless is disabled or not associated to network)
轉咗做low freq嘅channel (channel 40) 先穩定用到
唯有係咁先。

Thinkpad X390 ethernet bugs on Linux

個driver冇問題 但default個ethernet config唔知做乜搞到bandwidth限咗100mbps
個fix:

Fix meta key mapping problem to kde plasma default panel.

有咩問題?

你應該知道係KDE Plasma有個比較玄嘅設計：
就係Meta key (Windows Key) 係會被map成組合鍵Alt + F1，
而更加奇怪嘅係，
當你用完Lattle Dock, Set好咗呢一個組合鍵去Trigger Application Launcher，再轉翻用default panel之後；
個組合鍵係會神奇地唔work。

What is Cryptsetup and LUKS


Cryptsetup is a utility used to conveniently set up disk encryption based

on the DMCrypt kernel module.

These include plain dm-crypt volumes, LUKS volumes, loop-AES

and TrueCrypt (including VeraCrypt extension) formats.

The project also includes a veritysetup utility used to conveniently setup

DMVerity block integrity checking kernel module

and, since version 2.0,  integritysetup to setup

DMIntegrity block integrity kernel module.
