Ngethamsanqa le bug kwi-LightDM sele ilungisiwe kunye nohlaziyo lwamva nje luya kusivumela ukuba sikhuseleke kwaye sikhuselwe kwakhona. Into enomdla kukuba, le bug ichaphazela kuphela iinguqulelo eziyi-16.10 kunye ne-17.04, iinguqulelo ezikwe-systemd. Kwaye kubonakala ngathi ezinye zeephakeji ezisetyenzisiweyo kolu tshintsho kwisistim ngoyena nobangela walo mngxunya wokhuseleko.

Ukongeza, ingxaki ayisiyongxaki njengakwezinye iinkqubo zokusebenza kuba umsebenzisi kufuneka abekho phambi kwekhompyuter ukuze akwazi ukwenza lo mkhwa, Oko kukuthi, Ukuphathwa gadalala kude kwezokhuseleko akunakwenzeka.
