This is on Dell G15 5525’s brightness keys in Linux Mint XFCE 21.1 Vera.

The installation of the system was easy-peasy and most features worked out of box.
The missing was proprietary Nvidia-drivers which resulted in a periodic warnings and ugly freezes. The thing easy to fix – e.g. via Software Center.

Then I found that brightness function keys are dead. On a basis of the discussion

https://bbs.archlinux.org/viewtopic.php?id=282356

I did the following (in a terminal – [Ctrl]+[Alt]+[t]):

First searching a device:

$ brightnessctl --list | grep -A 2 'backlight'
Device 'nvidia_0' of class 'backlight':
Current brightness: 100 (100%)
Max brightness: 100
Device 'nvidia_wmi_ec_backlight' of class 'backlight':
Current brightness: 12 (5%)
Max brightness: 255
Device 'amdgpu_bl0' of class 'backlight':
Current brightness: 47 (18%)
Max brightness: 255

Testing:

$ sudo brightnessctl --device='amdgpu_bl0' set +5%
Updated device 'amdgpu_bl0':
Device 'amdgpu_bl0' of class 'backlight':
Current brightness: 60 (24%)
Max brightness: 255

$ sudo brightnessctl --device='amdgpu_bl0' set 5%-
Updated device 'amdgpu_bl0':
Device 'amdgpu_bl0' of class 'backlight':
Current brightness: 47 (18%)
Max brightness: 255

Giving privileges to all users by the new file

$ sudo visudo /etc/sudoers.d/brightnessctl

# 2023-07-03
ALL ALL = NOPASSWD:/usr/bin/brightnessctl

And the last thing is to create shortcuts by Settings Manager – Keyboard – Application Shortcuts:

The End

Issue

After the upgrade Mint 20.3 Una do 21.0 Vanessa VMware’s VMPlayer stopped working!
Usuaully, after every update touching a kernel when I try VMPlayer I get the warnnig-window about necesary vmnet and vmmon modues update. But this time I couldn’t pass this step.

user$ sudo vmplayer #run in "xterm"

I found the error at the latest log

Solution

I found such answers for the issue:

https://communities.vmware.com/t5/VMware-Workstation-Pro/Virtual-ethernet-failed/td-p/2906720

https://communities.vmware.com/t5/VMware-Workstation-Pro/Vmware-kernal-Module-updater/td-p/2920375

and build a procedure for myself, on this basis.

As I understand README

https://github.com/mkubecek/vmware-host-modules

it’s a need to (re)build vmmon and vmnet modules for a kernel
while the rest has been upstreamed for some time.

RESTART the system!

otherwise, re-test of a vm-entity will give an error : vmplayer could not open /dev/vmmon

So they (a vendor) wants you to look if an application failure has a system cause?

I see a change coming from a private experience, transforming the professional life. We are less email-client-oriented with its calendar, notes, tasks. We incorporate chat tools enriched by cooperative enhancements.

I was wondering, should this site be a professional advertisement or just a hobby-related? But the true is that nowadays we mix it often. A year ago I learned ‘weisure’-word on an english class and here is the definition: https://www.macmillandictionary.com/dictionary/british/weisure
