Uyakwazi lokho nokho Ubuntu buqinile, hhayi ngaso sonke isikhathi ubuwula. Kwesinye isikhathi, uhlelo lokusebenza noma i-bug ingahle ilenge uhlelo futhi ingakuvumeli ukuthi uqalise ikhonsoli ukwenza noma yikuphi ukusebenza noma ukuqala kabusha ikhompyutha, njll. Kulezo zimo ezimbi lapho ungenakho okunye okukhiphayo, esikhundleni sokucima okokusebenza ngokucindezela nokubamba inkinobho yokuvula / yokuvala noma ngenkinobho yokusetha kabusha, unenye inketho.
Le nketho ukucindezela inhlanganisela yokhiye njengoba injalo Isikrini sokuphrinta se-Alt + REISUB. Lokho kwenza ukuthi uhlelo luphendule futhi luqalise kabusha ukuphuma kuleso simo esiqandisiwe. Khumbula ukuthi kufanele ubambe izinkinobho zesikrini se-Alt + Phrinta bese ucindezela izinkinobho ezilandelayo ngamunye ngamunye ngaphandle kokuzibamba zonke ngasikhathi sinye (kusobala): R, E, I, S, U, no-B. Inkinga ukuthi kungenzeka ingasebenzi kunguqulo ethile ye-Ubuntu ...
Okwenziwa yilomsebenzi ukusebenzisa i-a SysReq (Isicelo Sesistimu) noma isicelo sohlelo ukuze i-kernel iphendule kuleso sicelo futhi, kulokhu, iqalise kabusha uhlelo olufriziwe. Izinkinobho zisetshenziselwa:
- A: Ibuyisela ukulawula kukhibhodi noma i-unRaw.
- E: Susa zonke izinqubo noma i-tErm.
- Mina: bulala izinqubo ezisele noma i-fullkIll.
- S: Vumelanisa amadiski noma Vumelanisa.
- U - Faka zonke izinhlelo zamafayela njengokufunda kuphela noma i-Umount.
- B: qala kabusha ikhompyutha noma uqalise kabusha iBoot.
Uma inguqulo yakho yohlelo ikhutshazwe ngokuzenzakalela, ingalungiswa kalula. Ngoba uyisebenzise bese uhlelo luhambela ukulandelana ezilandela i-Alt + Imp Pant ukwenza imisebenzi ehlukile (ngoba kukhona okuningi kunalokhu engikukhombisile), kufanele wenze okulandelayo:
echo "kernel.sysrq = 1" >> /etc/sysctl.d/99-sysctl.conf
Enye inketho ukusebenzisa umyalo olandelayo ongaba nawo umphumela ofanayo:
sysctl -w kernel.sysrq=1Khumbula ukuthi kwimiyalo yangaphambilini udinga amalungelo, ngakho-ke kwenze okungcono ngeSudo noma, ukwehluleka lokho, njengezimpande.
Futhi kusukela manje kuqhubeke, inhlanganisela yokhiye kufanele isebenze ... Khumbula ukuthi uma uyiguqula kufayela le / proc / sys / kernel / sysrq, izosebenza, kepha ngeke isinde lapho uqala kabusha uhlelo, ngakho-ke uzoba ukuyiguqula futhi. Okusho ukuthi, akuhlali unomphela.
Okuningi ngomlingo SysRq
Lokho osanda kukwenza ngomyalo ovela kudivayisi eyedlule ukushintsha ukucushwa kwe-kernel ukuyibeka kunani lika-1 elenza yonke imisebenzi ye-SysRq. Kepha kufanele wazi ukuthi kukhona amanye amanani angenzeka, uma ngabe unentshisekelo yokuyisebenzisa:
- 0 - Khubaza iSysRq ngokuphelele.
- 1 - Nika amandla zonke izici ze-SysRq.
- > 1: bit mask ukuvumela imisebenzi ethile:
- 2 - Inika amandla ukulawula kwe-console ezingeni le-log.
- 4: nika amandla ukulawula ikhibhodi (SAK, unraw)
- 8 - Nika amandla ukulahlwa kwenqubo yokulungisa iphutha, njll.
- 16: nika amandla umyalo wokuvumelanisa.
- 32: inika amandla ukubuyela emuva ngemodi yokufunda kuphela.
- 64: vumela ukusayinda kwenqubo (isikhathi, ukubulala, ukubulala oom)
- 128: vumela ukuqala kabusha / i-poweroff.
- 176 - Ivumela ukuvumelanisa kuphela, qalisa phansi, futhi uphinde ubuye ngemodi yokufunda kuphela.
- I-256: ivumela ukubonwa kwayo yonke imisebenzi ye-RT
Lokho kusho futhi kukhona ezinye okhiye umlingo ngaphandle kwe-R, E, S, I, U, B, ongayisebenzisa ukwenza izicelo ezithile ohlelweni lokusebenza. Zingasetshenziswa ngokulandelana njenge-RESIUB, kepha futhi zihlukaniswe, njenge-Alt + Screenprint + S, Alt + Screenprint + B, njll. Futhi ukuze wazi amathuba amaningi, nalu uhlu:
- B: qala kabusha ikhompyutha ngokungaphephile. Lokho wukuthi, ngaphandle kokuvumelanisa ama-disk buffers, noma ukwehlisa okokuhlukaniswa okukhishiwe. Lokhu kungadala ukuthi idatha ilahleke noma enye idatha ebibhalwa yonakaliswe. Kufana nokucindezela inkinobho yokusetha kabusha ngokomzimba noma ukucindezela inkinobho ye-ON / OFF yenye imishini ephathekayo noma i-AIO.
- C: iphoqa ukuphahlazeka, ilahle imemori yohlelo eyinhloko kudiski.
- D: izofaka ukukhiya kwesistimu.
- E: ithumela isiginali ye-SIGTERM kuzo zonke izinqubo ngaphandle kwe-init / systemd / upstart,… Okusho ukuthi, ibulala zonke izinqubo ezisebenzayo ngaphandle kwaleyo.
- F: icela i-OOM Kill, ukuxazulula amanye amacala lapho uhlelo luphelelwe yimemori.
- G: faka imodi yokulungisa iphutha yekhonsoli, usebenzisa i-framebuffer.
- H: izokhombisa usizo ekusebenziseni iSysRq.
- J: iphoqa ukubanda kohlelo lwefayela noma amasistimu wefayela ngokusebenzisa i-FIFREEZE.
- K: bulala zonke izinqubo zekhonsoli ozisebenzisayo. Lokho kufaka negrafu.
- L: ikhombisa ukubuyela emuva kwesitaki kwawo wonke ama-CPU asebenzayo ohlelweni. Uma kukhona okungasebenzi noma okhubazekile ngokwenza, ngeke kubonise lutho ngazo.
- M: ikhombisa imininingwane evela kwimemori yakho.
- N: setha kabusha kokuzenzakalelayo kokuhle kuzo zonke izinqubo ezisezingeni eliphakeme nezinqubo zeRealTime. Lokho kuzonciphisa izinkinga zokubanga izinsiza.
- Noma: izovala ikhompyutha ngokuphelele. Lokho wukuthi, ayihlali njengokuma.
- P: bonisa amarejista namafulegi.
- Q: bonisa zonke izibali sikhathi nezinsizakusebenza zewashi.
- A: Shintsha imodi yekhibhodi kusuka ku-RAW iye ku-XLATE.
- S: izovumelanisa ama-buffers ediski noma amadiski, okungukuthi, izinkumbulo ezigcina imisebenzi yokufinyelela ezokwenziwa. Ngakho-ke idatha yakho ayonakaliseki uma ususa idrayivu noma uqala kabusha ngokuzumayo.
- T: ikhombisa uhlu lwemisebenzi.
- U: shintsha imodi ekhuphukayo yokwahlukanisa ibe eyokufunda kuphela noma yokufunda kuphela.
- V: phoqa ukusethwa kabusha kwekhonsoli ye-framebuffer.
- W: ikukhombisa uhlu lwemisebenzi evinjiwe.
- Ibha yesikhala: izobonisa izinkinobho zomlingo ze-SysRq ezitholakala kwikhompyutha yakho.
Khumbula ukuthi akuzona zonke lezi ezizosebenza ngazo zonke izindlela ...
