Login fail

[barkingbandicoot]

Login is temperamental! Sometimes it works, sometimes not. Sometimes I have to reboot, and reboot.
If I log back in from the screen lock it will only work if I hit the arrow. Enter appears to perhaps do a backspace.
nb. This behaviour many have started after upgrade to Mantic.

[barkingbandicoot]

SOLVED: After trying a few things, I added backports and this solved the issue.

[barkingbandicoot]

False alarm!
The behaviour has returned!
I can only consistently login with the virtual keyboard now.

could you give us a little more info about the Machine? Make, Model, Ram, Etc. Do you see any error messages on boot?

[barkingbandicoot]

Hi. no messages on boot - but quiet splash is on. Are there logs to be found somewhere?

you can look in /var/log/boot.log But you will have to be administrator to do so.
if you want to use dolphin launch it with this command in a terminal then navigate to /var/log/boot.log

pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY KDE_SESSION_VERSION=5 KDE_FULL_SESSION=true dolphin

(copy and paste to avoid mistakes. )

See if you see any errors especially in ACPI.
good luck.

Failed to start networking.service is the only FAILED I see.
This boot logged straight in though!

In the auth.log this came up a lot:

you can try appending this to the grub boot line.

• sudo nano /etc/default/grub
• Change line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

If it makes no difference revert to the original.
