Ukukhishwa kwe-Ubuntu 18.04.4 LTS ngesitaki sezithombe kanye nokuvuselelwa kwe-Linux kernel

Kwethulwa isibuyekezo sokusabalalisa Ubuntu 18.04.4 LTS, okuhlanganisa izinguquko ezihlobene nokuthuthukisa ukusekelwa kwezingxenyekazi zekhompuyutha, ukubuyekeza i-Linux kernel nesitaki sezithombe, kanye nokulungisa amaphutha kusifaki ne-bootloader. Ukwakheka kufaka phakathi izibuyekezo zakamuva zamaphakheji angamakhulu amaningana ahlobene nokuqeda ubuthakathaka и izinkinga, okuthinta ukuzinza. Ngesikhathi esifanayo, okufanayo izibuyekezo Kubuntu 18.04.4 LTS, Ubuntu Budgie 18.04.4 LTS, Ubuntu MATE 18.04.4 LTS, Lubuntu 18.04.4 LTS, Ubuntu Kylin 18.04.4 LTS kanye ne-Xubuntu 18.04.4 LTS.

Kufakwe ekukhululweni wangena okunye ukuthuthukiswa okubuyiselwe emuva kusukela ekukhululweni Ubuntu 19.10:

• Kuphakanyiswe isibuyekezo sephakheji le-Kernel 5.3 (Ubuntu 18.04 busebenzise i-kernel 4.15, Ubuntu 18.04.2 obusebenzisa i-4.18, Ubuntu 18.04.3 busebenzise i-5.0);
• Kubuyekeziwe izingxenye zesitaki sezithombe, okuhlanganisa ukukhishwa okusha kwe-Mesa 19.2, X.Org Server 1.20.5 kanye ne-libdrm 2.44.99, ezihlolwe ku-Ubuntu 19.10. Izinguqulo ezintsha zabashayeli bevidiyo be-Intel, AMD kanye ne-NVIDIA chips zengeziwe (kuhlanganise nomshayeli we-NVIDIA 435 wokuphathelene);
• Izinguqulo zephakheji ezibuyekeziwe i-OpenJDK 11 (i-OpenJDK 8 ihanjiswe endaweni yokugcina yonke indawo), i-OpenSSL 1.1.1 (i-OpenSSL 1.0.2n esele njengenketho), i-thunderbird 68.2.2, dpdk 17.11.6, snapd 2.42, 19.4.33 cloud.11.0 cloud.2.9.5 vula -vm-amathuluzi XNUMX, openvswitch XNUMX;
• Ukuqanjwa kungezwe inkonzo okokugcina, okuvumela ukuthi ukhiqize okuqukethwe kwenkomba ye-/run/initramfs, ezosetshenziswa ku-systemd-shutdown esigabeni sokuvala isistimu, lapho ukuhlukaniswa kwezimpande sekuvele kwehlisiwe;
• В shiftfs, i-FS ebonakalayo yokwenza imephu amaphuzu okukhweza ezindaweni zamagama abasebenzisi, usekelo olungeziwe lwemodi yokufaka/yokukhiphayo okuqondile (O_DIRECT, sebenza ngaphandle kokubhafa futhi udlule inqolobane);
• Ukwesekwa okungeziwe kokuzama kabusha ukuzama ukulanda uma kwenzeka yehluleka kuhlelo lokusebenza lwe-snap-Tool;
• Iphakheji yengeziwe wslu ngezilungiselelo nezinsiza zokuhlanganisa Ubuntu nemvelo I-WSL (I-Windows Subsystem ye-Linux);
• Kusoftware ye-gnome, izigaba zezinhlelo zokusebenza ezitholakala ngohla lwemibhalo lwephakheji ye-snap zibuyekeziwe;
• Iphakheji ye-ubuntu-web-launchers isusiwe ohlwini lwezinhlelo zokusebenza ezinconyiwe;
• Ku-Thunderbird, ngokushintshanisa amafayela kumodi ye-FileLink, lapho okunamathiselwe kugcinwa khona ezinsizeni zangaphandle futhi isixhumanisi kuphela sesitoreji sangaphandle sithunyelwa njengengxenye yencwadi, isevisi ye-WeTransfer inikwe amandla ngokuzenzakalelayo.

В imihlangano Kudeskithophu, i-kernel entsha nesitaki sezithombe kunikezwa ngokuzenzakalelayo. Kuzinhlelo zeseva, i-kernel entsha yengezwa njengenketho kusifaki. Kunengqondo ukusebenzisa izakhiwo ezintsha zokufakwa okusha - amasistimu afakwe ngaphambili angathola zonke izinguquko ezikhona ku-Ubuntu 18.04.4 ngohlelo lokufaka lokuvuselela olujwayelekile.

Ake sikukhumbuze ukuthi ukulethwa kwezinguqulo ezintsha ze-kernel ne-graphics stack kuyasebenza imodeli yokusekela yokuvuselela, ngokuya ngokuthi yiziphi izikhwebu ezibuyiselwe emuva kanye namashayeli azosekelwa kuphela kuze kukhishwe isibuyekezo esilandelayo sokulungisa segatsha le-LTS le-Ubuntu. Isibonelo, i-Linux 5.3 kernel enikelwe ekukhishweni kwamanje izosekelwa kuze kube yilapho kukhululwa Ubuntu 18.04.5, ezohlinzeka nge-kernel evela ku-Ubuntu 20.04. I-4.15 base kernel ethunyelwe ekuqaleni izosekelwa kuwo wonke umjikelezo wokulungisa. Ukusekelwa kokukhishwa kwe-LTS kwe-Ubuntu 18.04 kuzohlala kuze kube ngu-Ephreli 2023, ngemuva kwalokho eminye iminyaka emi-5 izokwakhiwa izibuyekezo njengengxenye yosekelo olukhokhelwayo oluhlukene (i-ESM, Ukugcinwa Kwezokuphepha Okunwetshiwe).

Ukuze uthuthele ukufakwa okukhona kuzinguqulo ezintsha ze-kernel nesitaki sezithombe iyaqhubeka sebenzisa umyalo:

I-sudo apt-get install --install-incoma i-linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
