Kutulutsidwa kwa Ubuntu 18.04.4 LTS yokhala ndi zithunzi zosinthidwa ndi Linux kernel

Zaperekedwa Kusintha kogawa Ubuntu 18.04.4 LTS, zomwe zikuphatikizapo kusintha kokhudzana ndi kukonza chithandizo cha hardware, kukonzanso Linux kernel ndi graphics stack, ndi kukonza zolakwika mu installer ndi bootloader. Zolembazo zikuphatikizanso zosintha zaposachedwa zamaphukusi mazana angapo okhudzana ndi kuchotsa zofooka и mavuto, kukhudza kukhazikika. Pa nthawi yomweyo, zofanana zosintha 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 ndi Xubuntu 18.04.4 LTS.

Kuphatikizidwa mu kumasulidwa adalowa zosintha zina zabwera pambuyo pakumasulidwa Ubuntu 19.10:

• Kusintha kwa phukusi la Kernel kwaperekedwa 5.3 (Ubuntu 18.04 idagwiritsa ntchito kernel 4.15, Ubuntu 18.04.2 idagwiritsa ntchito 4.18, Ubuntu 18.04.3 idagwiritsa ntchito 5.0);
• Zasinthidwa graphics stack, kuphatikizapo zatsopano za Mesa 19.2, X.Org Server 1.20.5 ndi libdrm 2.44.99, zomwe zinayesedwa pa Ubuntu 19.10. Makanema atsopano oyendetsa makanema a Intel, AMD ndi NVIDIA tchipisi awonjezedwa (kuphatikiza dalaivala wa NVIDIA 435);
• Mitundu yosinthidwa ya phukusi ya OpenJDK 11 (OpenJDK 8 idasamukira kumalo osungira chilengedwe), OpenSSL 1.1.1 (OpenSSL 1.0.2n kumanzere ngati njira), thunderbird 68.2.2, dpdk 17.11.6, snapd 2.42, 19.4.33 cloud.11.0 kutsegula -vm-zida 2.9.5, openvswitch XNUMX;
• The zikuchokera anawonjezera utumiki chomaliza, zomwe zimakulolani kuti mupange zomwe zili mu /run/initramfs directory, zomwe zidzagwiritsidwe ntchito mu systemd-shutdown pa sitepe yotseka, pamene kugawa kwa mizu kwachotsedwa kale;
• В shiftfs, FS yeniyeni yopangira mapu okwera malo ogwiritsira ntchito, kuwonjezera chithandizo cha njira yolowera / zotulutsa (O_DIRECT, gwirani ntchito popanda kubisa ndi kudutsa posungira);
• Thandizo lowonjezera pakuyesanso kuyesa kutsitsa ngati kulephera kugwiritsa ntchito chida cha snap-Tool;
• Phukusi lawonjezeredwa wslu ndi zoikamo ndi zofunikira zophatikizira Ubuntu ndi chilengedwe WSL (Windows Subsystem ya Linux);
• Mu mapulogalamu a gnome, magulu a mapulogalamu omwe akupezeka kudzera muzolemba za phukusi lasinthidwa;
• Phukusi la ubuntu-web-launcher lachotsedwa pamndandanda wamapulogalamu ovomerezeka;
• Ku Thunderbird, posinthana mafayilo mu FileLink mode, momwe cholumikizira chimasungidwa mu mautumiki akunja ndipo cholumikizira chokha chosungira kunja chimatumizidwa monga gawo la kalatayo, ntchito ya WeTransfer imathandizidwa mwachisawawa.

В misonkhano Kwa desktop, kernel yatsopano ndi zithunzi zojambulidwa zimaperekedwa mwachisawawa. Kwa makina a seva, kernel yatsopano imawonjezedwa ngati njira yosungira. Ndizomveka kugwiritsa ntchito zomangamanga zatsopano - machitidwe omwe adayikidwa kale amatha kulandira zosintha zonse zomwe zilipo mu Ubuntu 18.04.4 kudzera mudongosolo lokhazikika lokhazikitsira.

Tikukumbutseni kuti pakubweretsa mitundu yatsopano ya kernel ndi graphics stack kuyikidwa mtundu wothandizira wosinthira, malinga ndi zomwe ma kernels ndi madalaivala omwe amabwerera kumbuyo adzathandizidwa pokhapokha kukonzanso kotsatira kwa nthambi ya LTS ya Ubuntu kutulutsidwa. Mwachitsanzo, kernel ya Linux 5.3 yomwe yaperekedwa pakutulutsidwa kwapano idzathandizidwa mpaka kutulutsidwa kwa Ubuntu 18.04.5, yomwe ipereka kernel kuchokera ku Ubuntu 20.04. 4.15 base kernel yomwe idatumizidwa koyambirira idzathandizidwa panthawi yonse yokonza. Thandizo la kutulutsidwa kwa LTS kwa Ubuntu 18.04 lidzatha mpaka Epulo 2023, pambuyo pake zaka 5 zina. adzapangidwa zosintha monga gawo la chithandizo cholipidwa chosiyana (ESM, Kusamalira Chitetezo Chowonjezera).

Kusamutsa zoyika zomwe zilipo kumitundu yatsopano ya kernel ndi graphics stack ayenera kukhala yendetsani lamulo:

sudo apt-get install --install-imalimbikitsa linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
