В maassemblies Yedesktop, iyo nyowani kernel uye giraidhi stack zvinopihwa nekukasira. Kune maseva masisitimu, iyo kernel nyowani inowedzerwa senge sarudzo mune inosimudza. Izvo chete zvine musoro kushandisa zvivakwa zvitsva zvekumisikidzwa - masisitimu akaiswa kare anogona kugamuchira shanduko dzese dziripo muUbuntu 18.04.4 kuburikidza neyakajairwa yekuisa sisitimu.

Ngatikuyeuchidzei kuti pakuunzwa kweshanduro itsva dze kernel uye graphics stack kuiswa rolling update inotsigira modhi, maererano neiyo backported kernels uye vatyairi vanozotsigirwa chete kusvika inotevera yekugadziridza yekuvandudza yeLTS bazi reUbuntu yaburitswa. Semuenzaniso, iyo Linux 5.3 kernel yakapihwa mukuburitswa kwazvino ichatsigirwa kusvika kuburitswa kweUbuntu 18.04.5, iyo ichapa iyo kernel kubva kuUbuntu 20.04. Iyo 4.15 base kernel inotumirwa pakutanga ichatsigirwa mukati menguva yese yekugadzirisa. Tsigiro yekuburitswa kweLTS kweUbuntu 18.04 ichagara kusvika Kubvumbi 2023, mushure mezvo mamwe makore mashanu. ichaumbwa inogadziridza sechikamu chekutsigira kwakabhadharwa kwakasiyana (ESM, Yakawedzerwa Chengetedzo Yekuchengetedza).

Kutamisa zvimisikidzo zviripo kune zvitsva zve kernel uye grafiti stack ndinofanira mhanya murairo:

sudo apt-get install --install-inokurudzira linux-generic-ye-18.04 xserver-xorg-ye-18.04
