UNvidia Optimus kukhompyutha yakho ephathekayo yeLinux efaka iBumblebee

Yini iNvidia Optimus?

Lobu buchwepheshe abubusha, kungashiwo nje ukuthi kuthuthukiswa iHybrid SLI ne "Hybrid Graphics" endala, eyavumela ukuphathwa kwamandla lapho uhlanganisa iNvidia GPU nebhodi elinoNvidia Chipset kudeskithophu, manje i-Optimus isivumela ukuthi siyenze okufanayo kuma-laptops ethu anama-processor we-Intel Sandy Brigde (i3, i5, kanye ne-i7) kanye noNvidia Gpu. Ngamazwi alulaLobu buchwepheshe bukuvumela ukuthi ushintshe phakathi kwehluzo ezihlukanisiwe nezinikezelwe ngokuya ngesidingo, okusho ukuthi, uma siqhuba igeyimu yevidiyo, uhlelo luzisebenzela ngokuzenzakalelayo imidwebo ezinikele, esikhundleni salokho uma sibuka ibhayisikobho, izosebenzisa imidwebo ehlukile. Futhi ngamagama anzima kakhudlwana:

“Ngokungafani nezizukulwane zangaphambilini zama-laptops, amakhadi emidwebo yesimanjemanje axhunywe yisiteshi sehadiwe ku-IGP yama-processor we-Intel ngakho-ke ayikho indlela yokukhubaza imidwebo ye-processor ukusebenzisa nje ikhadi lemifanekiso elizinikele. Iprosesa isebenza njengesiteshi sokudlula, lapho ikhadi lehluzo elizinikele likwimodi yokulala, i-chipset yemidwebo isetshenziselwa ukunikeza imidwebo, idlulisa imininingwane kusiqaphi sangaphakathi ngesixhumi se-LVDS se-laptop. Kodwa-ke, uma kusetshenziswa ikhadi lehluzo elizinikele, imininingwane kufanele futhi idlule kwi-chipset yemifanekiso ukuze ifinyelele kumqapha, ngenxa yalesi sizathu akunakwenzeka ukuthi kusebenze iprosesa IGP ngokomzimba ngakho-ke yonke le nqubo yokwenza kusebenze nokwenza kungasebenzi kufanele yenziwe nge-software, kulokhu isilawuli. » (I-Leanuxeros.com)

Ku-Windows lokhu kusebenza kahle (ngingasho okuhle, kepha siyazi ukuthi akukho lutho olusebenza kahle ngamawindi) naku- LinuxNgokushintsha, akukho ukusekelwa okusemthethweni okuvela kuNvidia futhi ngokusho kwezindaba engikwazile ukuzifunda abananhloso yokwenza kanjalo esikhathini esifushane noma esimaphakathi, kulokho kungezwa ukuthi kumakhompiyutha amaningi ayikho inketho yokwenza kusebenze / khubaza elinye lamagrafu usebenzisa i- I-Bios, okusishiya sinesimo esidumaza kakhulu ngoba esimweni lapho kuphela i- Kuhlanganiswe utshalomali ku I-GPU enikezelwe iya emgqonyeni kadoti, esikhundleni salokho uma unayo Izithombe zeNvidia ukusebenza (lokhu kuyinto ejwayelekile) ukusebenza kwamandla kuzosenza sikhumbule iMatrix futhi sibukeke kahle emcabangweni wokuguqula isihlobo noma umakhelwane ibhethri, ngoba, njengoba sonke sazi, kusuka I-Kernel 2.6.38  Amabhethri aphathekayo ayanqanyulwa futhi ukuzimela sekuyigama eliwusizo lokwenza izingoma zokubhikisha (kimi ibhethri lahlala amahora amabili ubude)

Kungakho ohlangothini lweLinux lamandla, sekuvele amaphrojekthi wokuxhasa lobu buchwepheshe kepha ngaphandle kwempumelelo enkulu, kuze kube yilokho Bumblebee. Bumblebee iyithuluzi lomthombo ovulekile elibhalwe ngolimi lwe-C, lisivumela ukuthi sisebenzise umshayeli ophethe i-Nvidia noma inguqulo yamahhala new, ezinsukwini ezimbalwa ezedlule i-3.0 version yethulwe okuthe phakathi kokunye okusha okusivumela ukuthi sisebenzise ngokuzenzakalela imenenja yamandla ngokwenza kusebenze noma kungasebenzi i-GPU ezinikele ngokuya ngezidingo zecala (okuyilokho okubalulekile kithi).

Singafaka iBumblebee kufayela lomthombo elitholakala ku- https://github.com/Bumblebee-Project/Bumblebee/downloads

Kunamaphakeji ezinqolobaneni ze- Ubuntu, I-Gentoo, Arch y Debian.
Ngafaka lolu hlelo lokusebenza kuma-distros amabili engiwasebenzisayo: Debian y Arch ngokulandela izinkomba zama-Wikis abo.

Ukufakwa kwe-Arch

Siyafaka Bumblebee kusukela I-AUR

$ yaourt -S bumblebee

Futhi siyafaka i-bswitch ukwazi ukuphatha umphathi wamandla

$ yaourt -S bbswitch

Ngomshayeli weNouveau

Uma uzohlala abashayeli new kufanele ufake amaphakheji alandelayo:

$ sudo pacman -S xf86-video-nouveau nouveau-dri mesa

NgeNvidia ephathelene

Uma usebenzisa abashayeli beNvidia abaphethe, sifaka lawa maphakeji avela ku-AUR.

$ yaourt -S nvidia-utils-bumblebee dkms-nvidia

Isethaphu

Sengeza umsebenzisi wethu eqenjini Inyosi enkulu enkulu:

# usermod -a -G bumblebee $USER (reemplazamos $USER por nuestro usuario)

Sivivinya ukuthi konke kufakwe kahle futhi kusebenza ngokuqhuma i-bumblebee ngesandla:

$ sudo rc.d start bumblebeed

Nemilingo… iNvidia GPU ayisebenzi futhi sisele naleyo edidiyelwe, ngenhlanhla sinika ibhethri lethu ikhefu.

Ngokulandelayo sihlela  /etc/rc.conf

Sengeza Bumblebee ku AmaDemoni

DAEMONS=(... bumblebeed)

Sahlola

$ optirun glxspheres

Siyabona ukuthi okuhlanganisiwe kuyasebenza futhi ekugcineni kwenqubo kuyacisha ukunikela kokuzinikele, uma ufuna ukwenza uhlelo lokusebenza neNvidia GPU siyenza kusuka kukhonsoli

$ optirun [opciones] <aplicaciones>

Ukubona uhlu lwezinketho:

$ optirun --help

Ukuze ikhadi elizinikele livule / livule ngokuzenzakalela sengeza I-Bbswitch esigabeni samaModyuli:

MODULES=(... bbswitch …)

Siyahlela  /etc/bumblebee/bumblebee.conf futhi sengeza umugqa olandelayo esigabeni sabashayeli:

[bumblebeed] KeepUnusedXServer=false

Siyakuqinisekisa lokho PMMethod lokhu emotweni:

[driver-nvidia] PMMethod=auto

[driver-nouveau] PMMethod=auto

Siqala kabusha i- bumblebee:

# rc.d restart bumblebeed

Ukufaka ku-Debian (Kuphela Ukuhlolwa noma i-Sid)

Okokuqala kufanele ususe noma yikuphi ukufakwa kwangaphambilini kwe-Bumblebee, lapho-ke sinika amandla amakhosombe non-mahhala.
Ukuqalisa izinhlelo zokusebenza ezingama-32 kumasistimu angama-64 kunconywa ukufaka amaphakheji alandelayo:

$ sudo aptitude install virtualgl-libs-ia32 and libgl1-nvidia-glx-ia32

Sifaka lawa makhosombe ku  /etc/apt/sources.list

deb http://suwako.nomanga.net/debian sid main contrib
deb-src http://suwako.nomanga.net/debian sid main

Ngemuva kwalokho sehlisa ukhiye bese siyengeza:

# wget -O - http://suwako.nomanga.net/suwako.asc | apt-key add -

Sibuyekeza:

# aptitude update

Sifaka:

# aptitude install bumblebee bumblebee-nvidia

Sengeza umsebenzisi wethu eqenjini le-Bumblebee:

# adduser $USER bumblebee (reemplazamos $USER por nuestro usuario)

Siqala kabusha futhi sihlole ukuthi isebenza no:

$ optirun glxgears

Uma sifuna ukusebenzisa uhlelo nge-GPU ezinikele, sikwenza ngokulandelayo esigungwini

$ optirun <aplicación>

Ukuqedela ngingakutshela ukuthi ulwazi lwami ngalolu hlelo lokusebenza lube luhle impela, abanye abangane abavela DesdeLinux bangibonile ngidela ekhanda ngizama ngingaphumeleli ukufaka abashayeli beNvidia abaphethe kuma-distros engiwasebenzisayo (iDebian ne-Arch), ngaze ngazithela eBumblebee, ngakolunye uhlangothi, ibhethri elihlala amahora amabili laya isilinganiso amahora amathathu nesigamu futhi izinga lokushisa le-laptop lehle lisuka ku-54 ° laya ku-45 °.

Kubonakala kimi ukuthi inqobo nje uma uNvidia enganqumi ukuxhasa ngokusemthethweni i-Optimus ku-Linux, noma uma ungenantshisekelo yokuba nabashayeli bezimpahla kodwa usebenzisa i-Nvidia GPU yakho, iBumblebee iyindlela enhle kakhulu.
