Sa ou manaʻomia le faʻaalia o se dashboard ma le mataʻituina i luga o le tele o lau i le ofisa. E i ai le tele o Raspberry Pi Model B + tuai ma se hypervisor e toetoe lava a le fa'atapula'aina le aofa'i o punaoa.
E foliga mai o le Raspberry Pi Model B + e le lava le faʻaogaina e faʻaauau ai le faʻaogaina o le browser ma faʻaalia le tele o ata i totonu, ona o le mea lea e tupu ai o le itulau o se vaega o le taavale ma e masani ona paʻu.
Sa i ai se tali faigofie ma matagofie, lea ou te manaʻo e faʻasoa atu ia te oe.
E pei ona e iloa, o Raspberries uma o loʻo i ai se faʻagaioiga vitio mamana, lea e lelei tele mo le faʻaogaina o ata vitio. O lea na sau ai le manatu e faʻalauiloa se suʻesuʻega ma se dashboard i se isi mea, ma faʻafeiloaʻi se vaitafe ua saunia ma se ata na tuʻuina atu i le rasipi.
E le gata i lea, e tatau ona faʻafaigofie le pulega, talu ai i lenei tulaga o le a faia uma faʻatulagaga i luga o le masini komepiuta e tasi, lea e faigofie ona faʻafouina ma faʻasaʻo.
E le'i leva ona fai.
Vaega server
Matou te faʻaaogaina saunia . Le manaʻomia le faʻapipiʻiina, o loʻo i ai mea uma e te manaʻomia e faʻapipiʻi vave ai se masini masini, ma fesoasoani e faʻapipiʻi vave se fesoʻotaʻiga, faʻaopoopo ssh ki ma faʻavave ona faʻaogaina.
Matou te faʻapipiʻiina se masini komepiuta fou ma muamua faʻapipiʻi i luga , и :
apt-get update
apt-get install -y xserver-xorg nodm fluxbox
sed -i 's/^NODM_USER=.*/NODM_USER=ubuntu/' /etc/default/nodmO le a matou faʻaogaina foʻi le config mo Xorg, agalelei matou Diego Ongaro, faʻaopoopo naʻo se iugafono fou 1920 × 1080, talu ai o le a faʻaaogaina e matou siaki uma:

systemctl restart nodmO lenei o le a matou faʻapipiʻi Firefox, matou te faʻatautaia e avea o se auaunaga faʻapitoa, o lea mo le mea e tasi o le a matou tusia se faila faila mo ia:
apt-get install -y firefox xdotool

EOT
systemctl enable firefox
systemctl start firefoxMatou te manaʻomia Xdotool ina ia faʻatautaia vave le firefox i le ata atoa.
Fa'aaogaina o le parakalafa -url e mafai ona e faʻamaonia soʻo se itulau ina ia tatala otometi pe a amata le suʻega.
I lenei laʻasaga, ua saunia le matou kiosk, ae o lea e manaʻomia le faʻatau atu o le ata i luga o le upega tafaʻilagi i isi siaki ma masini. Ina ia faia lenei mea, o le a matou faʻaogaina avanoa , o se fa'asologa e masani ona fa'aoga mo le fa'asalalauina o vitio mai le tele o webcams.
Mo lenei mea matou te manaʻomia ni mea se lua: ma le module , mo le pueina o ata mai le x ma , lea o le a tufatufaina atu ia matou tagata faʻatau:
apt-get install -y make gcc ffmpeg

Sei o tatou taumafai e alu i , i le tali atu o le a e vaʻai i se faʻamalama faʻafouina o le desktop. Matagofie! — mea sa manaomia.
Itu fa'atau
E faigofie lava iinei, e pei ona ou fai atu, o le a matou faʻaaogaina le Raspberry Pi Model B +.
Muamua, tatou fa'apipi'i , o le mea lea tatou te mulimuli ai luga o le nofoaga aloaia.
Matou te manaʻomia foʻi le faʻasoaina o le tele o manatuaga mo la matou puʻupuʻu vitio, aua o le a matou faʻasaʻo i totonu /boot/config.txt
gpu_mem=128Se'i o tatou fa'agasolo la tatou faiga fou ma 'aua ne'i galo e amata le pacman keyring, fa'apipi'i :
pacman -Sy omxplayerO le mea e ofo ai, e mafai e le OMXPlayer ona galue e aunoa ma le x, o lea na pau lava le mea tatou te manaʻomia o le tusia lea o se faila faila mo ia ma tamoe:

Pau lava lena, o se ata mai la matou 'auʻaunaga e tatau ona vave faʻaalia i luga o le lau fesoʻotaʻi. A iai ni fa'afitauli, o le a otometi lava ona toe amata le vaitafe ma toe fa'afeso'ota'i ai tagata fa'atau.
I le avea ai o se ponesi, e mafai ona e faʻapipiʻi le ata o loʻo iʻu i ai e fai ma screensaver i luga o komepiuta uma i le ofisa. Mo lenei mea e te manaʻomia и :
