Kwiintsuku ezimbalwa ezidlulileyo yenziwe iposti kwiforum ye-Ubuntu, apho yenaAbaphuhlisi beCanonical baqaphele ukuba imeko ye desktop "Igobolondo elihle" kuhlobo lwe-Ubuntu 19.04, esekwe kwiGnome 3.32, yayicotha kancinci kunezinye iimeko zedesktop.
Ekuqaleni bekucingelwa ukuba isizathu kukusetyenziswa kweJavaScript, kodwa kwavela ukuba iJavaScript yayilishumi leepesenti kuphela zekhowudi ngokudityaniswa kweGnome Shell kunye nomphathi wefestile yeMutter kwaye ayisiyiyo le nto inoxanduva lokucotha.
Ukucinga okulandelayo kukuba isoftware yayilayisha umthwalo kwi-CPU okanye kwimizobo yamakhadi. Kodwa imilinganiselo ibonakalisile ukuba oku akunjalo. Into evelileyo endaweni yoko kukuba iiprosesa zanyanzeliswa ukuba zihlale zingenzi nto ixesha elide.
Into ebalulekileyo ekufuneka uyiqaphele apha kukuba uninzi lwekhowudi yemithombo ikwiprojekthi yeMutter, hayi iGnome Shell. Ngokubanzi, malunga ne-10% kuphela yeGnome Shell ebhalwe kwiJavaScript xa ucinga iMutter, kwaye malunga ne-90% ibhaliwe kwiC.
Ngoko ke, abaphuhlisi babenako ukujonga uphando lwabo ngexesha, ekubhekiswe kuyo kwinqaku njenge "xesha lokwenyani." Kungenxa yokuba inkqubo yeGnome neMutter iluphu yomnyhadala Glib nganye kumsonto omnye, badla ngokulibaziseka.
Nakuphi na ukulibaziseka kunokubangela ukuba esinye sezakhelo sitsibatsibe ezenza umfanekiso kwisuphavayiza. Oku kubonakala kumqolo obonakalayo womsebenzisi ekubekeni esweni.
Ngokulinganisa ii-lags ezahlukeneyo, abaphuhlisi bafumene ngaphantsi kwesiqingatha se-Gnome bugs esisigxina kwi-Gnome 3.34.
Impazamo yokuqala ikhokelele ekutsiweni kwesakhelo kuba emva kokulibaziseka kwenkqubo yesakhelo ngeemilisecond ezimbalwa, ixesha apho isakhelo bekuya kufuneka sakhiwe kwakhona lalibalwe ngokungachanekanga.
Kodwa ukulungisa le mpazamo, ebingasoloko isenzeka, yenze umboniso waba lula ngakumbi.
Okwesibini, lAbaphuhlisi bafumanise ukuba phantse zonke izakhelo zilibazisekile kwi-X.org kuba ukubalwa kwetafile kusetwe kwangethuba kakhulu. Kwinqanaba lesakhelo se-60 Hz, isikrini salibaziseka nge-16 ms.
Kule meko iWayland ayichaphazeleki. Enye impazamo ichaphazela iWayland kuphela. Ingxaki kukuba ku-Mutter, isantya sokubonisa isikhombisi semouse sasetwa kwi-60Hz.Oku kunokubangela iingxaki ukuya kuthi ga kwi-100% yokusetyenziswa kweCPU ukuba inqanaba lokuhlaziya lahlukile.
Kwakhona UMutter wayenenye ingxaki esele isonjululwe ngokuyinxenye ukuza kuthi ga ngoku. Ngenxa yoko, yonke imicimbi yegalelo yalibaziseka kwisakhelo esilandelayo, oko kukuthi, ukuya kuthi ga kwi-16 ms kwi-60 Hz.
Olunye ulibaziseko lubangelwe kukulungiswa kwabaqhubi beNvidia abanelungelo kwiX.org, ezingasafunekiyo ngoku.
Kwaye kwagqitywa enye ingxaki, ichonga into echaphazela isikhombisi semouse, apho iifowuni ze-OpenGL zenziwe khona, oku kuchaphazela kakhulu kwaye kubangele amaxesha okulinda ongezelelweyo ngenxa yolungelelwaniso oluyimfuneko phakathi kweCPU kunye neGPU.
Nje ngeziphumo, IGnome 3.34 ikhawuleza kakhulu. Ya zimbini ezinye iingxaki ezaziwayo ezingekasonjululwa.
- Xa usebenzisa iimonitha ezininzi, ukungqubana kwi-Wayland backend kubangela ukulibaziseka okukhulu. Oku kufuneka kulungiswe ngokomphuhlisi kwi-Gnome 3.36 kwaye ke Ubuntu 20.04 ngokunjalo.
- Ingxaki yesibini kukuba ayilulo lonke ulibaziseko eMutter olusonjululwe okwangoku. Inqaku liphetha ngengcebiso malunga nokuba zeziphi iimpazamo onokuthi uziphephe xa usombulula ingxaki kunye nembono malunga nento oza kuyenza ngokulandelayo.
Ukuphucula IGnome kufuneka ibe ye-Ubuntu 20. 04 kwinani leziphuculo Yintoni ekufuneka bagxile kuyo? kwizixhobo zangoku nezibalekayo. Imiba eseleyo echaphazela iikhompyuter ezindala kunye nezicothayo kufuneka ziqwalaselwe kwaye zisonjululwe ku-Ubuntu 20.10.
Ukuba ufuna ukwazi ngakumbi malunga nokupapashwa, Ungajonga eli khonkco lilandelayo.
