Ubuntu / Manjaro Dual Boot Power Cut while on

Support
1

I have been using Manjaro as my main distro in dual boot for the last couple of days. Rather new to this as a computing student but I was understanding how to use it fine.

I needed to move the desktop computer upstairs and I believe it only went into suspend mode rather than shut down before the power was unplugged.

Then when I go back onto the computer when it’s setup upstairs I can log into Ubuntu fine with internet connection but when I get to manjaro KDE login screen, I can put in my password but then it freezes when I press login (Mouse continues to work but can’t click on anything, the login button looks pressed but just freezes)

I’m struggling to work out how to fix it from many articles on the internet. I know this one is arch but hoped it might be similar: [attached [bbs . archlinux . org / viewtopic.php?id=152284]
I don’t think I understnad the steps that were made to fix this?

Thank you very much for the help,
Peter

Do you have other users in Manjaro to try? If you can you know its a problem with your main account.
If not, in the login screen use CTRL+Alt+F2 to go to tty2, then try to log in from there.

3

Ah okay I’ll try that in tty2 when start work tomorrow morning and see what happens. Is there something I’d need to do if I get into tty2 to debug the problem more? Thank you very much

We will see from there, but a good first step is moving all your config files from your /home/username/ folder elsewhere (like a backup), so the next time you log in it will generate all of them from scratch.

This have to be umask=0077 … there is a zero missing.

boot on USB iso manjaro
open a terminal and a browser on this topic
and report

sudo manjaro-chroot -a
cat /etc/fstab
exit ( end-chroot )

Thanks everyone for the advice. I’ve only just had a chance to look at this again. It now can’t get to the login screen:

And then it freezes and doesn’t take me to login.

megavolt - It is now saying umask=0077

I’ll see if I can work out how to boot from a memory stick next and see if that helps

I unfortunately can’t send the screenshot but this is what I get:

Thank you very much!

My nvme0n1p1 says it’s type is fat32 whereas the other nvme sections all say ext4. Is that alright for them to be different?

10

Yes that would be /boot/efi and is supposedd to be FAT32

11

case 1 : UUID is false , /boot/efi is short in UUID for Fat32 (vfat )
you can check with USB iso manjaro

sudo lsblk -fs
12

Thank you, it comes up with this:

correct to mount 1 ( manjarolinux1 )
/etc/fstab for /boot for UUID CBDE-CFF6

sudo manjaro-chroot -a 
nano /etc/fstab
efibootmgr -v
exit

Okay, so I eventually managed to backup everything and re-install but my configuration backup copied over and come up with a similar problem again.
I managed to get into tty2 and move the configuration files I think? I re-started the computer and it did the same thing with the login button freezing.

When I get into tty2 and do ls -a, it looks like it has re-generated .config which looks good.

So, I assume it’s another file in my home/user folder. What shall I do to work out which file is causing the problem? I have a backup of the user home directory so loosing things shouldn’t be a problem. I assume .cache is deleted automatically?

.bash_history
.bash_logout
.bash_profile
.bashrc
.bashrc_functions
.bashrc_system
.cache
.config

Would it be worth some sort of file related to login GUI if that’s to do with it freezing at all?
