Slow boot, how do I configure for nosity boot?

I have 18.04 on a couple of cheap laptops. This version does not work well
with the wireless chipset, and audio on these machine, FYI 10.10 solves all
these issues, BUT I don not want to go to it, as it will be easier to go to
the next LTS FROM the previous LTS.

These machine take *forever* to boot to an X login. How can I configure to
watch the boot sequence , so I can diagnose this issue?

How do I change the colour of the prompt text in terminal emulators


I am running UbuntuMATE 16.04.x amd 19.10, on different computers.

In recent system updates, little green men infested my computers, and,
changed the text in the prompts in the terminal emulators (mate
terminal) to a lime green colour, which, on a white background, is
like having yellow on white.

Also, on my 16.04 system, the spacing has been changed, so it is now
<character><space<character><space><character>, etc.

I have downloaded and installed, using synaptic, every terminal
emulator that I could find, and, they all have this awful green colour
of the text of the prompts.

xubuntu 19.10 fails to install with /boot on different drive - grub-install error

I am trying to install xubuntu 19.10 on an NVME SSD which isn't
visible to the BIOS.

So I need to put /boot on a drive which *is* visible to the BIOS, I
have drives as follows:-

/dev/nvme0n1p1 2048 31250431 31248384 14.9G Linux swap
/dev/nvme0n1p2 31250432 2000408575 1969158144 939G Linux filesystem

/dev/sda1 4xxG Linux filesystem

I'm installing from a USB stick, the installation starts OK, when I
get to the disk allocation bit I select 'something else' and tell it
to mount / on /dev/nvme0n

Getting "No such device xxxx...." at boot but the device *does* exist

I have added a new ubuntu 19.10 installation to my existing ubuntu
19.04 system. The 19.10 is installed on an NVME SSD.

I have run os-prober which identifies the new 19.10 istallation
correctly and I've run update-grub to add it.

At boot I get the expected menu offering 19.04 as the default and
19.10 as a selectable option. However if I try and boot 19.10 it
fails with an error:-

error: no such device: c6ca1c2d-4837-48b9-8fa6-1ef47251d7b7

Fortunately it then just drops me back to the boot menu so I can boot

Running install doesn't offer to use new NVME/SSD disk drive, but fdisk sees it

I have a system currently running xubuntu 19.04.

I have added a new NVME SSD disk drive to it, my xubuntu 19.04
installation can see the new disk drive OK:-

Disk /dev/nvme0n1: 953.9 GiB, 1024209543168 bytes, 2000409264 sectors
Disk model: INTEL SSDPEKNW010T8
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

However when I run an xubuntu 19.10 install it doesn't offer to use
the NVME disk at all, how can I get the install to see and use the new
disk drive?

Configuring/using grub with grub-install and grub-mkconfig

I have been searching around (and asking questions) about how to add a

confused about the relationship between grub-mkconfig and grub-install.

So, is there a good tutorial anywhere about all this?

Webkit issue

Webkit has maxed out ALL the CPU cores on my box, which may be causing
problems. I shut down 2 browsers [w >20 tabs] that use it but that did
not change the CPU data in htop. How can I see ALL of the pgms that are

I was just sitting here, doing my stuff, when suddenly I had no network. I checked

question about PciExpress slots and SSDs

I have a Fujitsu Esprimo P910 system running xubuntu 19.04 to which I
am thinking of adding a bigger SSD. It already has a 128Gb SSD for

BOINC Manager not working after an update

I installed an update to Ubuntu 19.10 and now the "BOINC Manager" no longer

How can I find the program name that is executed when I click an icon that is

copy/paste problem

Recent problem which seems to be getting worse. Running Ubuntu 16.04
updated. I have 2 'files' windows open, highlight some files in #1,
release all mouse buttons, click on the highlighted files, hold down
shift key, drag to #2 window - and nothing happens. Repeat, repeat some
more and finally works on perhaps try #6-10 - finally moved the files.
Getting to be a pain. What might be going on and how can I restore the
original move/copy behavior? I have 15-20 'files' windows running and
usually select 2-4 of them on the screen to work with. I also have many
other pgms running as well.

using network printers, what non-cups things exist?

I spent most of yesterday trying to get an HP OfficeJet to print from 16.04
having had good luck previously using it and an older DeskJet as a scanner
with hp-scan. It turned out that
one problem was the cartridges- the color test page printed something
and then apparently the black and white text failed to print.
However, there were a lot of "failed filter" messages and using
lpr with raw output at least got a piece of paper to feed. I only
have a few peripherals at a time and print rarely. I don't
really need any of this stuff.

Nasty bug in vertical scrollbar


In using UbuntuMATE 16.04.x, a nasty bug in the vertical scrollbars,
keeps causing problems.

When I am scrolling down in a web page, in a browser window tab,
sometimes, a menu listing the tabs in the window, appears. Sometimes,
it jumps to another tab in the window. It just now, jumped browsers,
and, opened the tab in which I was scrolling down, in a new tab, in
another browser.

How do I eliminate this nasty bug?

wanted: suggestions for used Linux compatible notebooks


I need to buy 2 or 3 notebooks, and run Ubuntu on them. Feature-wise,
I know what I need, or so I hope. But I have NO idea which brand/model
they correspond to, and specs/prices/availability/linux compatibility
change continuously, so any feedback is welcome. Here we go:

* used/refurbished, max 4/5 years old.

No budget for new ones, and probably no need either, see below. But
also, regardless of price, don't want to risk on e.g 10yrs old
machines that may break any moment. What I buy now should last 2/3
years minimum.

Writing UbuntuMate image

I have a old laptop with Mate 15 and I need to update it.
I installed M15 originally with unetbootin (pretty sure at least)

on the site say by clicking on Restore Disk Image. The Unetbootin
gets an error saying no OS present and on the other a message quickly
flashes saying isoxxxx.bin missing.. not sure what it actually says

A possibility has occurred to me, and, I do not know whether it has

Recently, Ralf Mardorf posted a link in the thread about tiny kernels,
to a wikipedia comparison of "lightweight Linux distributions", that
can run with lesser resource requirements, than mainstream Linux

Fixed problem installing 19.10

I am running a virtual machine using Ubuntu 19.04 on a Synology DS918.
After several attempts the upgrade each time ended up with ‘Oh, no - something went wrong…’.

The following fixed the mess:
1. start upgrade via standard Software Updater - after very long time it ends up with the Oh,no… (it won’t help to log out!)
2. log in via ssh from another computer to the VM
3. sudo killall dpkg # (pgrep -f 'dpkg|apt’)
4. sudo dpkg --force-remove-reinstreq --remove nautilus-dropbox
5. sudo dpkg --configure -a
6. reboot
7. - the gnome desktop is back again
8. sudo apt autoremove --purge

Good luck

Else then selected the 40GB partition that I had already formatted as
ext4 (using gparted in a working Ubuntu 19.04 partition) and told it
to mount it as '/' and not to format, then told it to continue.
At this point it hangs with the wheel spinning. I left it for an

Problems with Mate


I don't know how it happened but whenever I mount a partition, Firefox
