#StackBounty: #windows-10 #google-chrome #keyboard #mouse Windows 10 intermittent keyboard/mouse lag

Bounty: 50

My keyboard/mouse input intermittently pauses throughout the day for about a half second to a full second and it happens maybe once every few minutes. It’s mostly just an annoyance when I’m using my computer for non-intensive tasks like using VSCode, Chrome, Word, Powerpoint, etc.

I recently started playing Squad and it happens constantly, making the game nearly unplayable. I’ve also noticed that it doesn’t seem to happen at all when I play Modern Warfare: Warzone. The latter is really peculiar because it suggests to me that not only is this issue not hardware performance related, but there is some way that certain applications can "fix" this issue.

I’ve also noticed that music and youtube doesn’t stop playing in the background when the freezes occurring, suggesting that it’s not a system hang-up but an input hang-up. It also seems to occur more frequently when I have a ton of tabs open in Chrome.

Are there any tips on some steps I can take to troubleshoot what’s going on?

Steps I’ve already taken:

  1. Monitor task manager while pauses occur. CPU/Memory never approach 50% when not in Squad
  2. Try keyboard/mouse on another computer, no issues

System Specs:

  • CPU: AMD Ryzen 5 3600
  • Ram: 32GB
  • OS: Win10 20H2 19042.985
  • VMem Size:
    4864 MB

EDIT: I tried updating my display drivers to the latest Radeon drivers and that fixed the issue with Squad. However, I’m still having issues with Chrome, VSCode, and even the Windows menu being really unresponsive.

Thanks in Advance

#StackBounty: #audio #keyboard #audio-volume How can I set the amount by which the sound keys increase/decrease volume?

Bounty: 50

On my laptop, when I press the volumeup/volumedown key, the sound lever go up/down by 10 units.

I can check that with alsamixer: when I press volume up, the sound level indeed go up by 10 points.

But I would like these keys to be less sensible: it would be nice if the level could go up/down by 5 points when I press a key (volume up/volume down).

I know that these rules are configured in /lib/udev/hwdb.d, but the only thing I found in these files is the use of the "volumeup" and "volumedown" keywords, but not the amount the button increase/decrease.

How could I do that ?

Is there a config file somewhere ?


I’m on arch, and I would like to know where the config is stored (if there is one)

I’m using pulseaudio, I don’t know if this can help

#StackBounty: #keyboard #terminal #zsh #input #oh-my-zsh Pound sign (£) rendered as <ffffffff> in zsh

Bounty: 50

Things I’ve ruled out

  • Terminal: works if I launch it with bash as shell
  • Keyboard layout: £ inserts fine in Vim, bash and Firefox
  • Unicode issues anywhere: emojis work in all applications

I can’t input £ in zsh, even when I launch bash, which probably means the ZSH Line Editor is at fault. But I can’t find out
how to make it work by using bindkey, even after some Google searching.

Can I use bindkey, or do I have to use something else?


Locale Variables (same in bash and zsh):

Also using oh-my-zsh with default theme

#StackBounty: #keyboard #shortcut-keys #xmodmap #xkb #remapping How can I remap my keyboard to create a lefthand numpad?

Bounty: 250

Like many smaller machines, my laptop’s keyboard is missing a dedicated numpad.

I can generally type without looking at my keyboard, but I am unable to blindly type numbers with the number row. That’s why I thought of converting the left side of my keyboard into a second-level numpad (e.g. Z = 0, X = 1. C = 2, V = 3, S = 4 and so on).

Another advantage would be the possiblity to quickly type numbers without taking the right hand off the mouse or moving the left hand across the entire keyboard.

Now I’m looking for a way to remap those keys to "create" the numpad, at best independent of the desktop environment, as I’m using multiple ones constantly. Also, it would be amazing if that mapping was portable, so I could set it up once and enable it for different keyboards/machines.

I know that it’s possible to modify the keymap directly inside /usr/share/X11/xkb/symbols/, but those allow only three modifiers (Shift, AltGr (on European keyboards) and Shift + AltGr) and they’re usually in use on the letter keys or require both hands to activate.

I thought of using either Super_L or a combination of Shift_L + Alt as modifier keys to access the numpad layer, since those combinations shouldn’t be in use and are easy to reach with one hand.

How could this be accomplished?

#StackBounty: #keyboard #input-device Simulating a Keypad with Raspberry PI

Bounty: 100

I have an electronic Lock I want to open with my Raspberry PI 3B+. Therefore I measured the Voltage that is sent from the Keypad to the Lock. Each Number has its own Voltage. (0 = 0.00V, 1 = 0.06V… etc). If no Signal is sent the Voltage is 3.46V. When I send the Code 1-1-1-1-1-1 (= 6 x 0.06V) with the keypad, the Lock unlocks. But when I send the same Voltage with the Raspberry PI it doesnt unlock. I measured it with my Multimeter and the Voltage is the same like with the Keypad.

The Python Script I use is very simple:

sgn = PWMLED(26) 
sgn.value = 1    # 3.28V

Depending on the Voltage I want to send I change the value.

I also connected a Capacitator to stabilize the Signal.

Does anyone have a clue what could be wrong?

Please help me get this working!

#StackBounty: #keyboard #keyboard-layout #language How to type the 'ro' kana and yen symbol directly with US keyboard?

Bounty: 50

I recently brought the Japanese 106/109 keyboard stickers for my US keyboard. I applied stickers and changed my hardware keyboard layout from English 101/102 to Japanese 106/109. Then I realized that I can’t type the Japanese ‘ro’ and yen symbol directly. After a bit of research, I found this guide. Unfortunately, this guide doesn’t work because I don’t own the Japanese keyboard. I tried powertoys to remap a certain key to type the ‘ro’ kana but I have no idea what is the virtual key number for this kana. I looked up this documentation and it doesn’t help because it didn’t include the ‘ro’ kana and yen symbol. Any ideas on how to configure my keyboard so I can type the ‘ro’ kana and yen symbol directly?

I use Windows 10 and Google IME to type Japanese.

#StackBounty: #kernel #keyboard #xorg #xserver #dead-keys Keyboard buffer issue with multi-byte characters (latin, diacritics) / dead k…

Bounty: 50

I write in Spanish and sometimes I use diacritics (ie multi-byte chars) with dead keys, for example "liberación" ("liberation" in Spanish). Usually I don’t have any problem, but when the GUI freeze or for any reason it can’t handle more input, when the text shows up the diacritic char jump to the first position on the/a keyboard buffer, displaying something like "óliberacin", which is very annoying since occur very often while chatting or writing an email (easier to test: aaaááaaa). Maybe a xserver or GNOME Shell or a kernel bug?

I have this problem since more than four years now, with several kernels, Ubuntu versions, hardware and versions of Firfeox and Chorme. I couldn’t find any pattern neither something strange on dmesg/journalctl//var/log files…

Setup: This happened to me since Ubuntu 16.04 LTS fresh install, kernel 4.4.0-62-generic; and even recently with 18.04 and 4.15.0-134-generic, GNOME Shell 3.28.4.

$ locale
$ im-config -l
ibus xim
$ im-config -m

$ env | grep "XMODIFIERS|IM_"

How can I debug to find where the problem might be?

Update 2021-01-23

I didn’t cross with this issue for a while, until today, typing from Desktop to Android (GSconnect→KDE Connect Keyboard).
