Ubuntu 18.x lossis siab dua: kev daws teeb meem yog tias kev sib xyaw Alt + Imp Pant + REISUB tsis ua haujlwm rau koj

RESIUB Ubuntu qhov tseem ceeb ua ke

Koj paub tias ho Ubuntu yog pob zeb tawv, tsis yog ib txwm ruamCov. Lub sijhawm, ib daim ntawv thov lossis kab laum yuav dai lub system thiab tsis tso cai rau koj tsa lub console kom ua txhua yam haujlwm lossis rov pib kho lub computer, thiab lwm yam. Hauv cov xwm txheej uas koj tsis muaj lwm yam tshwm sim, es tsis txhob tua cov khoom siv los ntawm nias thiab tuav lub khawm / khawm qhib lossis nrog pib dua khawm, koj muaj lwm txoj kev xaiv.

Qhov kev xaiv no tau nias ua ke ntawm cov yawm sij uas lawv tau Alt + Luam Ntawv + REISUBCov. Qhov ntawd ua rau lub kaw lus yoog thiab rov qab los tawm ntawm lub xeev khov ntawd. Nco ntsoov tias koj yuav tsum tuav Alt + Print Screen yuam sij thiab tom qab ntawd koj tuaj yeem nias cov yuam sij hauv qab no ib qho los ntawm ib qho tsis tas yuav tuav lawv txhua lub sijhawm (pom tseeb): R, E, I, S, U, thiab B. Qhov teeb meem yog tias nws yuav tsis ua haujlwm nyob rau qee qhov version ntawm Ubuntu ...

Qhov haujlwm no ua tau zoo li cas a SysReq (Qhov System thov) lossis thov kom lub kaw lus rau lub ntsiav los teb qhov kev thov ntawd thiab, qhov no, rov pib lub khov dej. Cov yuam sij yog siv los:

  • A: Xa rov qab tswj rau cov keyboard lossis unRaw.
  • E: Txiav tag nrho cov txheej txheem lossis tErm.
  • Kuv: tua cov txheej txheem uas seem lossis fullkIll.
  • S: synchronize lub discs lossis Sync.
  • U - Mount txhua cov file system li nyeem nkaus xwb los yog Umount.
  • B: rov pib kho lub computer lossis reBoot.

Yog tias koj lub khoos phis tawm ntawm lub cev ua tsis taus los ntawm lub neej ntawd, nws tuaj yeem kho tau yooj yim. Rau qhib nws thiab lub kaw lus koom ua ntu zuj zus uas ua raws Alt + Imp Pant los ua cov haujlwm sib txawv (vim tias muaj ntau dua li cov no uas kuv tau qhia), koj yuav tsum ua cov hauv qab no:

echo "kernel.sysrq = 1" >> /etc/sysctl.d/99-sysctl.conf

Lwm qhov kev xaiv yog siv cov lus txib nram qab uas yuav muaj tib cov nyhuv:

sysctl -w kernel.sysrq=1

Nco ntsoov tias rau cov lus txib yav dhau los koj xav tau cov cai, yog li ua nws zoo dua nrog sudo los yog, ua tsis tau, uas yog hauv paus.

Thiab txij no mus, cov kev sib xyaw tseem ceeb yuav tsum ua haujlwm ... Nco ntsoov tias yog koj hloov nws hauv / proc / sys / kernel / sysrq file, nws yuav ua haujlwm, tab sis nws yuav tsis muaj sia nyob thaum koj rov ua lub kaw lus, yog li koj yuav muaj hloov nws dua. Ntawd yog, nws tsis yog mus tas li.

Ntau txog khawv koob SysRq

Qhov koj nyuam qhuav tau ua nrog cov lus txib los ntawm lub tshuab ua ntej yog hloov lub ntsiav txheej txheem los teeb nws rau tus nqi ntawm 1 uas ua rau tag nrho SysRq zog. Tab sis koj yuav tsum paub tias muaj lwm qhov txiaj ntsig tau, yog tias koj xav siv lawv:

  • 0 - Lawb SysRq tag.
  • 1 - Siv tag nrho SysRq nta.
  • > 1: daim npog ntsej muag me ntsis tso cai rau qee yam haujlwm:
    • 2: hloov console tswj ntawm lub cav theem.
    • 4: pab kom keyboard tswj tau (SAK, unraw)
    • 8 - Siv cov txheej txheem debug pov tseg, thiab lwm yam.
    • 16: pab kom cov sync hais kom ua.
    • 32: pab txhawb kev qhia seem hauv txoj kev nyeem nkaus xwb.
    • 64: pab kom cov txheej txheem signaling (sij hawm, tua, oom-tua)
    • 128: cia rov ua haujlwm / poweroff.
    • 176 - Tso cai rau sync nkaus xwb, rov ua dua tshiab, thiab nyob rau hauv hom kev nyeem ntawv nkaus xwb.
    • 256: tso cai them tsis tau tag nrho cov haujlwm RT

Hais tias, dhau lawm muaj lwm tus yuam sij khawv koob uas tsis yog R, E, S, Kuv, U, B, uas koj tuaj yeem siv los ua qee qhov kev thov rau lub operating system. Lawv tuaj yeem siv ua ntu zus zoo li RESIUB, tab sis kuj cais tawm, zoo li Alt + Nthuav + S +, Alt + Vijtsam + B, thiab lwm yam. Thiab kom koj paub ntau tau, ntawm no yog cov npe:

  • B: rov kho lub computer kom tsis muaj teeb meem. Ntawd yog, tsis muaj synchronizing lub disk buffers, los yog unmounting lub mounted kev faib ua feem. Qhov no tuaj yeem ua rau cov ntaub ntawv yuav ploj lossis qee cov ntaub ntawv uas tau sau cia ua rau lub siab tsis ncaj. Nws zoo li nias lub khawm pib kho lub cev lossis nias ON / OFF khawm ntawm lwm cov khoom siv thauj khoom lossis AIO.
  • C: yuam kev sib tsoo, pov tseg qhov system system nco mus rau disk.
  • D: yuav nruab qhov system kaw.
  • E: xa SIGTERM teeb liab rau tag nrho cov txheej txheem tshwj tsis yog init / systemd / upstart,… Qhov ntawd yog, nws tua txhua tus txheej txheem khiav tshwj tsis yog ib qho ntawd.
  • F: foob rau OOM Tua, txhawm rau daws qee kis thaum cov kab ke tawm tsis nco.
  • G: sau console debug hom, siv framebuffer.
  • H: yuav qhia kev pab siv SysRq.
  • J: yuam kom khov ntawm cov filesystems lossis system los ntawm kev siv FIFREEZE.
  • K: tua txhua tus txheej txheem nplij koj siv. Qhov ntawd kuj suav nrog lub teeb.
  • L: qhia tau ib pawg backtrace ntawm txhua lub CPUs nquag hauv lub system. Yog tias muaj lub cev tsis ua haujlwm lossis siv lub cev xiam oob qhab, nws yuav tsis qhia txhua yam txog lawv.
  • M: qhia cov ntaub ntawv los ntawm koj lub cim xeeb.
  • N: pib dua rau niceness sai rau txhua qhov muaj feem thib siab thiab RealTime cov txheej txheem. Qhov ntawd yuav pab daws teeb meem kev sib cav sib ceg.
  • Lossis: nws yuav tua lub computer tag. Ntawd yog, nws tsis dormant zoo li halt.
  • P: qhia cov ntawv sau npe thiab chij chij.
