Windows and Linux logbook

Date: December 2020

• Windows 10: time is always outdated. I have to sync time every time I reboot.

• Windows 10: login never accepts password on first try. Known problem.

• Ubuntu: can't show network activity, because my motherboard seems to be too new?

• Ubuntu: 4k display and scaling means font sizes are all over the place. Spotify is tiny. Terminal font needs to be two points smaller to match what it is on macOS.

Solutions

• Final Ubuntu/Gnome settings resolution/scaling etc.:

  • 3840x2160, 60z, Scale: 100%
  • Font scaling in gnome-tweak-tools: 1.25
  • Kitty font size for Jetbrains Mono NL: font_size 11.0
  • VS Code font sizes: {"terminal.integrated.fontSize": 12, "editor.fontSize": 13}
  • Chrome default zoom: 125%

• Changing the scroll wheel speed in Ubuntu

  • Following this: https://dev.to/bbavouzet/ubuntu-20-04-mouse-scroll-wheel-speed-536o
  • Then in ~/.imwheelirc:

    ".*"
    None,      Up,   Button4, 4
    None,      Down, Button5, 4
    Control_L, Up,   Control_L|Button4
    Control_L, Down, Control_L|Button5
    Shift_L,   Up,   Shift_L|Button4
    Shift_L,   Down, Shift_L|Button5
    

  • I think the 4 is the speed in line 2 and 3
  • Then start it with: imwheel -b "4 5"
  • Added it to the startup applications of Ubuntu/Gnome

Debugging network activity not working on ubuntu

No network activity monitor shows any activity.

$ lspci | grep Ether
07:00.0 Ethernet controller: Intel Corporation Intel(R) Ethernet Controller I225-V (rev 02)

$ sudo dmesg | grep igc                                                                               -1-

$ sudo dmidecode | grep Product
        Product Name: System Product Name
        Product Name: ROG STRIX B550-F GAMING (WI-FI)

This works:

sudo iftop -i enp7s0 -n -N -t

I think it might be that the network controller, the "I225-V" is not well supported yet.
