I am not sure it is so but I tried to check disk and it said 0.8% of crypto swap is destroied.
Ubuntu start up and welcomome windows is here but I tried to use my password and it is not work.
Change password under Root from Recovery console is not functional. It said something wrong password unchanged.
QUEST login is functional without any problems.
Root console can't start gnome.
The case happened after last update.
How can I fix this ?
