Common Computer Issues

 ·  ☕ 6 min read

These are all the issues we discussed on a live stream. I took all the community questions and made this webpage for them.

Windows 10 - Automated Tasks

Q: How can I make a YouTube video sit there paused on someone’s screen in Windows 10 and instantly start playing aloud upon unlocking the screen/waking from sleep?

A: Task Scheduler can do all sorts of tasks and you can set the triggers to be on login or at certain times of the day.

Linux - Display Issues

Solution for Display constantly resetting or getting incorrectly configured

3 Solutions (All will work)

  • Xorg Custom Settings
    • When display render is launched it will automatically configure each display to these specification from /etc/X11/xorg.conf.d/10-monitor.conf

# /etc/X11/xorg.conf.d/10-monitor.conf
Section "Monitor"
### Monitor Identity - Typically HDMI-0 or DisplayPort-0
    Identifier    "HDMI1" 
    Option        "PreferredMode" "1920x1080"
    Option        "TargetRefresh" "60"

### Positioning the Monitor
## Basic
    Option "LeftOf or RightOf or Above or Below" "DisplayPort-0"    
## Advanced
    Option        "Position" "1680 0" #Note you can always set both to 0 0 to mirror
## Disable a Monitor
     Option        "Disable" "true"
EndSection 
  • Autorandr - Automatic monitor settings
  • Xrandr Script
    • Make a custom bash script and set with login manager, cron job, or set in ~/.xinitrc

Sample xrandr script:

1
2
#!/bin/bash
xrandr --output HDMI-1 --off --output HDMI-2 --auto

Note: You can use the tool arandr to grab the proper display script

Windows/Linux/MacOS - Flashing Images to SD-Card or USB

There are so many solutions for this one:

Linux - Boot Time High for KDE

               267ms minidlna.service
               217ms NetworkManager.service
               200ms nvidia-persistenced.service
               196ms upower.service
               189ms systemd-logind.service

Note: Also try systemd-analyze critical-chain or systemd-analyze plot > boot.svg as this shows the chain of the startup

Linux - USB Port stops working

  • Check to see if device shows on lsusb
  • Check dmesg for errors dmesg | grep -i USB
  • Run usb-devices
  • Disable Auto Suspend
    • cat /sys/module/usbcore/parameters/autosuspend result should be 2 which means enabled
    • Modify Grub or bootloader to disable auto suspend (for grub modify /etc/default/grub)
      • GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"
      • sudo update-grub
    • Verify by running cat command again

Linux - Fixing No Display Drivers or Black Screen or Missing Desktop Environment

Ctrl + Alt + F1 or F2

This drops you to TTY and no display drivers are needed. From this console you can fix things by installing display drivers or missing packages you need.

All Computers - Can’t Get into BIOS

Open it up and remove the CMOS Battery. Press the power button without it plugged in to fully discharge. Then wait 60 seconds and put CMOS battery back in.

General PC Maintenance - Updates & Shuting them down

Updates should be done weekly with security only one applied. Feature Updates should be delayed at least 1 year. This is universal across all operating systems. I also recommend shutting down your PC every day and not using suspend/hibernate. If you want to schedule the updates you can leave your PC once a week overnight.

Windows/Linux - Time Maintenance

You should use UTC time everywhere. Windows uses local time and it is terrible. Change this with a registry setting

  • Disable Internet Time on Windows 10
    • Head to Settings > Time & language and disable “Set time automatically”.
  • Modify Windows Registry to use UTC
    • Start - Run - regedit
    • Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation
    • Create new DWORD (32-bit) Value RealTimeIsUniversal
    • Set Value to 1
  • You can also use REG files from this project https://github.com/ChrisTitusTech/Windows-10-UTC if you don’t want to manually edit registry

MacOS - OpenCore and Safety

Opencore is a completely open project and is safe. Here is the github of OpenCore where they expose all their code for review https://github.com/acidanthera/OpenCorePkg and the complete install guide is here https://dortania.github.io/OpenCore-Install-Guide/

Linux Battery Life and Laptop Heat

There are a variety of packages you can use, but highly suggest two:

  • tlp
  • xfce4-power-manager

TLP will throttle your CPU and use less power and XFCE power manager will take care of brightness, suspend, and other power saving features as a standalone package even if you aren’t using XFCE as a desktop environment.

MacOS - OpenCore Audio Issues

This typically comes from using two codecs or the wrong one. Use ONLY ONE!

Linux - App won’t launch it just disappears…

Run Application in Terminal and look at the errors. Chances are it is missing a dependency.

Windows - “these settings are managed by your organization”

Chances are you ran a powershell script (maybe mine…) and you are now locked out of changing the lock screen on your Windows Box. Run this command in powershell to gain control of your lock screen again:

1
Remove-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\Personalization" -Name "NoLockScreen" -ErrorAction SilentlyContinue

OR

You can also open up Start - Run - gpedit.msc and then go to All Settings and look for enabled features and set them to Not Configured

Windows - Reinstall OneDrive

Open Up PowerShell Admin (Right Click Start Button)

1
%systemroot%\SysWOW64\OneDriveSetup.exe
