☆ capslock/brightness

/sys/devices$ find . -type f -name brightness
./platform/i8042/serio0/input/input0/input0::scrolllock/brightness
./platform/i8042/serio0/input/input0/input0::capslock/brightness
./platform/i8042/serio0/input/input0/input0::numlock/brightness
./pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight/brightness
./pci0000:00/0000:00:14.0/usb1/1-5/1-5:1.0/rtsx_usb_sdmmc.1.auto/leds/mmc0::/brightness

/sys/devices/platform/i8042/serio0/input/input0/input0::capslock$ sudo \
> sh -c "echo 1 > brightness"

すると、CapsLockキーのLEDが点灯した。
しかし、CapsLock機能は有効にならなかった。

とりあえずは、これだけ。

☆ なんか好いみたい

購入後3日目で我慢できず、Win10を消すと、UEFIを何も変えなくとも busterがあっさり入った。
sidにあげてしばらく遊ぶことにする。

☆ i7z

温度上昇を防ぐには、というあたりを少し読んで、thermaidを入れた。その次に あったi7z(1)を実行してみた。

☆ cpupwer(1)

これも適当にやって、次はいつになるか。

$ sudo cpupower -c 1 frequency-info 
analyzing CPU 1:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 1
  CPUs which need to have their frequency coordinated by software: 1
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 400 MHz - 4.60 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 400 MHz and 4.60 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 2.44 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes

☆ waifu2x

bionicで動くなら、busterでも動くだろうとやってみた。
インストールは問題なくできた。 nvidiaのドライバはnon-free(nvidia謹製と思われた)だったが、

$ waifu2x-converter-cpp -l
   0: Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz     (FMA       ): num_core=8

だけ。
以前のページに 貼った写真を4倍に拡大してみる。

6秒余りかけて waifu2x-converterで拡大した写真と、 ほとんど瞬時にできた、 imagemagickで拡大した写真。
