WebComer's questions

I'm changing some existing Ubuntu 18.04 install from AMD to Intel motherboard.

On booting with Intel mobo, it stopped to boot in the end with a complain that

Timed out waiting for device dev-di...y\x2dduid-6E6274DB6274AA0B.dev...

Dependency failed for /mnt/6E6274DB6274AA0B.

1. Is it possible to boot on Intel mb previous AMD mb installation?
2. How to fix this os install to run on the Intel motherboard?

There is a question similar, that states that it is possible in reverse case, Intel to AMD, and insist on removing GPU driver first before change.

Migrating from Intel CPU to AMD one

My both installs on the motherboards are with NVidia GPUs, very similar.

3. Can I remove bad driver or whatever else or should I still try to remove some GPU driver?

Note. There is somewhat looking as a file or folder

/mnt/6E6274DB6274AA0B

when drive in accessed from PE Win10. Deleting it results in completely broken boot, so I have to restore it by check.

1. Is it possible to fix the install trying to reinstall from Live flash drive?

UPDATE:

I checked file /etc/fstab contents, and it is as follows:

*# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name
devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda5 during installation
UUID=7d79a32e-4cae-4c47-9736-9ef5e96f15d9 /               ext4    errors=remount-ro 0       1
/swapfile                                 none            swap    sw              0       0
/dev/disk/by-uuid/6E6274DB6274AA0B /mnt/6E6274DB6274AA0B auto nosuid,nodev,nofail,x-gvfs-show 0 0*

So despite of nofail option, as it was advised, for example, in

https://unix.stackexchange.com/questions/326791/cannot-boot-because-missing-external-disk

boot still fail. Should I just remove the mounting point in this file, or do something else to get rid of the issue?

UPDATE:

I did comment last string

# /dev/disk/by-uuid/6E6274DB6274AA0B

and boot a bit continued, but stuck at

“Started Update UTMP about System Runlevel Changes",

which is as far as I can see in questions may be a problem with repository update, graphical driver and other reasons.

So, how to troubleshoot and fix the issue?

May be, it's possible to fix the install trying to reinstall from Live flash drive?

I've installed latest Ubuntu 18.04.1 LTS about a week ago.
All the soft was installed via system menu or Jetbrains repo.

In 2 days appeared freezes - only mouse moves, irresponsive to keyboard, timer above the window don't tick. For several days it was 1 freeze a day in the evening, then 2 freezes in the evening, yesterday 5 freezes, today - 5 times.

I daily do update/upgrade.

My keyboard don't have SysReq button.

Ctrl+Alt+F2/F3 worked only once, once Ctrl+Alt+ScrollLock added somewhat in appeared console stream.

I googled around and find this post advising to get to /etc/default/grub and changing the default line to GRUB_CMDLINE_LINUX_DEFAULT="noacpi" and then running sudo update-grub.

Then i had my 5 freezes yesterday. Sometimes after crash Ubuntu asks for sending crash report, sometimes not.

My questions are:

1. How to get to console and collect info/reason for a crash?
2. Is it possible to recover from crash without reset or power down button?
3. How to properly collect info/reason for a crash to send it to Ubuntu (preferably automatically)?

There is an advice to change kernel in this link.
The kernel in my setup is 4.15.0-39-generic. But it is not in a list of available stable kernels.

Should I change to another kernel in order to get stable system?

Yes, memtest does appear in my GRUB menu. I'll give it a try tonight. Dual-boot Windows 7 don't show any problems so far.

Just have found quite similar issue with LibreOffice 5.1 / Ubuntu 16.04:

Turned off Java in my LibreOffice, OpenCL already off. No luck. 3 freezes in 2 hours. Last time touching LibreOffice after a pause freeze everything but mouse again. Installed NVidia driver v.340. Let' see.

Sometimes i copy/paste text from browser to LibreOffice, and page formatting|stylings from the browser page spoil the text looking ugly, like this, for example:

Sometimes those frames|images|tables can be selected with mouse and deleted, but sometimes not.

How to delete them completely? Vb or Python macro would be especially appreciated.

I'm trying to set up Thunderbird with secondary mail account and want it to leave messages on server. There was such a feature, at least in Windows earlier, like this:

But I can't see those tick box in current setup of the newest Thunderbird in Ubuntu 18.04:

How to set the email client in proper way?

Update:

If you want to setup POP protocol in Thunderbird, you may do it manually this way if you need it.
