Ubuntu 18.04 (dual boot with Windows 10) on Dell Inspiron 5593.
This only happens when the laptop is not plugged in.
If I lock my screen or close my laptop, the computer suspends. When I try to wake the computer, I see my login screen, but I can't type my password. It just keeps displaying "Authentication Error." (I've seen a fix for this here,
and configuring )
fs.inotify.max_user_watches solved my problem when plugged in, but not when unplugged.
During the "Authentication Error" cycle, if I try
F3, or if enough time passes, I'll see an endless stream of error messages; something like this:
EXT4-fs error (device nvme0n1p5) __ext4_find_entry:1532: inode #13894512: block 5557614: comm gmain: reading directory Iblock 0 EXT4-fs error (device nvme0n1p5) __ext4_get_inode_loc:4704: inode #13894512: block 5557614: comm systemd-journal: unable to read itable block
fsck from a USB boot shows no errors.
It's also been suggested here that I should try downgrading the kernel, but that didn't help me either.
Can this be solved, or do I have a hardware malfunction?
Update I've just experienced this problem again when the computer was plugged in.
