接上篇。隔了很久之後才更新arch,次日又發現兩個問題。

御阪10358發表於2020-12-29
  1. 當滑鼠游標在Chromium中時,經常閃爍,無論游標是靜止還是移動,都會不停地閃爍,但是在檔案管理器中時就不會閃爍。不知道什麼原因,但是現在已經基本不閃爍了(只有當滑鼠游標指向的東西是含有超連結的或是需要彈出“那種含有進一步說明資訊的小框框”的 才會閃爍幾下)。
  2. 還有一個問題就是,有時開機以後,會出現兩個滑鼠游標:一個是固定在螢幕中心的,無法移動,一個是可以自由移動的“真正”的游標。將自由移動的游標移到螢幕中心的那個游標,二者重合時,是固定的那個游標在上,可自由移動的游標在下。 不知道這是什麼引起的,但是reboot以後就沒有這個情況了,但是可能下一次開機,就又會出現。遂將出現上述情況時和出現以後進行reboot後的systemctl status的輸出資訊進行了比較,發現了兩處不同——一個是app.slice下:正常情況時,其下只有一個dbus.service,但是出現兩個游標時,其下還會有一個at-spi-dbus-bus.service,然後搞出了at-spi-bus-launcher、accessibility、gnome session,且在dbus.service下會比正常情況時多出一個/usr/lib/xfce4/xfconf/xfconfd。看到有accessibility的東西,不知道是不是和官網的latest news中提到的accessibility features有關;另一處不同是在system.slice下的systemd-udevd.service下,正常情況時,其下有25個/usr/lib/systemd/systemd-udevd (這些udevd應該是和開機以後啟用一些“快捷鍵”有關,比如觸控板、無線按鈕、音量按鈕、螢幕亮度等),然後還會執行/bin/bash /usr/bin/monitor.sh (這個的內容是依照官網wiki中寫的,檢測一下有無外接顯示器,並用xrandr設定解析度。開機後是用/etc/udev下的顯示器熱插拔rules執行monitor.sh。),但是出現兩個游標的情況時,只有一個systemd-udevd,然後就什麼都沒了。這兩處出現的不同,均搞不懂原因……
    (還有一個想說的就是在用了acpid調整開機時的螢幕亮度時,生效時間很慢很慢,剛開圖形介面時亮度為100,然後得等個幾分鐘,acpid才能將螢幕亮度降低為預設值。我記得之前(2020年年初重灌系統前)是沒有用acpid來管理開機亮度的,那時好像每次通過xbacklight設定了亮度後,下一次開機時亮度是和上次一樣的,不會自動重設為100,但是重灌後,就不行了,每次開機都會變成100,所以才使用acpi自動設定開機亮度,但是每次生效時間都很長……)

以下是出現兩個游標時的systemctl status:
