Kashe wasan bidiyo na gida lokacin amfani da x11vnc

Sannun ku,

Akwai labarai da yawa akan Intanet akan batun yadda ake saita haɗin nesa zuwa zaman Xorg da ake da shi ta hanyar x11vnc, amma ban sami ko'ina ba yadda ake murkushe mai saka idanu na gida da shigar da shi ta yadda duk wanda ke zaune kusa da kwamfutar ta nesa ya yi. kada ku ga abin da kuke yi kuma baya danna maɓalli a cikin zaman ku. A ƙasa da yanke shine hanyata don yin x11vnc mafi kama da haɗawa zuwa Windows ta hanyar RDP.

Don haka, bari mu ce kun riga kun san yadda ake amfani da x11vnc, idan ba haka ba, kuna iya google ko karanta misali. a nan.

An ba: muna ƙaddamar da x11nvc, haɗa shi tare da abokin ciniki, komai yana aiki, amma na'ura mai kwakwalwa ta gida kuma yana samuwa don dubawa da shigarwa.

Muna so: kashe na'urar wasan bidiyo na gida (mai duba + madannai + linzamin kwamfuta) don kada a iya gani ko shigar da komai.

Kashe masu saka idanu

Abu na farko da ya zo a zuciya shi ne kawai kashe mai duba ta hanyar xrandr, misali kamar haka:

$ xrandr --output CRT1 --off

amma a lokaci guda, yanayin taga (Ina da KDE) ya fara tunanin cewa an kashe mai saka idanu kuma ya fara jefa windows da bangarori, komai yana motsawa kuma ya zama bakin ciki.
Akwai hanya mafi ban sha'awa, wacce ita ce aika mai saka idanu zuwa cikin kwanciyar hankali, zaku iya yin wannan misali kamar haka:

$ xset dpms force off

amma a nan ma, ba komai ba ne mai santsi. Tsarin yana tada mai saka idanu a taron farko. Ƙunƙwasa mafi sauƙi a cikin hanyar zagayowar yana taimakawa:

while :
do
    xset dpms force off
    sleep .5
done

Ban yi tunanin kara ba - Na kasance kasala, yana aiki da manufarsa - masu saka idanu ba sa nuna komai, koda kuwa na danna maballin, motsa linzamin kwamfuta, da sauransu.

UPS:

Спасибо amariya don wata hanya tare da juya haske zuwa sifili:

$ xrandr --output CRT1 --brightness 0

Yanke abin shigar

Don musaki shigarwa na yi amfani da xinput. Lokacin da aka ƙaddamar ba tare da sigogi ba, yana nuna jerin na'urori:

$ xinput

Na'urori Mahimman bayanai ... ba za ku iya kashe shi ba - an nuna kuskure, amma sauran za a iya kunna da kashewa, alal misali, wannan shine yadda za ku iya barin ku ba tare da linzamin kwamfuta na minti daya ba:

xinput disable 9; sleep 60; xinput enable 9
