[xubuntu-users] Some Problems with 19.10 and my ThinkPad T480s

[Klaus Maas]

Dear Christian,

I might be able to offer some help with some items.

1)

A felt 25sec still seems long.

I once had a similar problem. It was related to the system trying to 
load/look for assistive technologies.

It improved after I explicitly uninstalled them.

Try to have look at your text messages at boot up and see where it 
spends its time ob.

Also run in a terminal:

$ systemd-analyze blame

list boot processes sorted descending by time, but only after kernel loaded

$ systemd-analyze plot > graph.svg

produces an svg which also shows you how much time is spent by firmware, 
bootloader, Linux kernel and then all the services.
pre-kernel background is white, Linux kernel = grey, serice running = 
light red with initialisation duration of that service in red

6)

On one of my systems - Tuxedo BC1510 - I am running Xubuntu 18.04 as my 
default OS (Tuxedo Systems' ships Budgie - not my cup of tea).

Xubuntu 18.04:

When my screen blanked I could not wake it up again. Just staid dark.

Suspending the system through menu or by closing the screen also 
produced the dark screen problem.

Keyboard, touchpad, mouse, I pressed and swished on anything I could 
find/think of, nothing helped.

Eventually I discouvered I could log in again on the dark screen. I just 
had to wait long enough.

The system was still responding but the screen never showed me the login 
screen because the screen is dark.

- waking up a dark screen does not work

- locking and unlocking DOES work - even on a dark screen

So this is my workaround:

A) Screen just went dark, but I want to continue working right away:

Lock (ctrl+alt+L) - unlock (ctrl+alt+L) - enter password - Enter

B) Change Power Manager Settings

Tab Display

Blank after:    x minutes    (e.g. 10 minutes)

Put to sleep after: x+1 minutes  (e.g. 11 minutes - the closest I can 
get after the blank time).

Somehow this also fixed my suspend issues.

So my recommendation is:

Try fiddling around with the Power Manager Settings.

3)

The easiest way to adjust system fonts:

Note:  Affects all system apps / menus / Thunar file mangager / TASKBAR 
/ ...

Whisker menu (ctrl+esc) -> type ap for appearance, Enter -> tab FONTS

do any of those:

click on font name / font size to change it

change DPI setting at the bottom

5)

The recent Linux-Welt 2020/2 has a topic somewhere in the back informing 
on how to teach Linux screen resolutions it couldn't / didn't recognize 
automatically.

Don't have it handy. Not my copy.


Success!

Klaus
