To fix chromium border, go to Settings -> Use system title bar and borders

To "enable" pdf scrolling with vimium, get PDF Viewer from chromium store.

Also add dash to /bin/sh I guess?

Wechat font

If you see square boxes (and you installed deepin-wine-wechat), maybe try the following (as described on github):

After 3.5.0.46-2, the font is bugged (also the emotes), but to fix the font you can download 微软雅黑 fake_simsun.ttc on this link (the guy put up baidu yunpan here with password 96qm). I have a copy in this repo as well.

After you download it, just put it into the folder $HOME/.deepinwine/Deepin-WeChat/drive_c/windows/Fonts and everything should work fine.

Playing Paladins on Steam

Currently (as of May 2022), Proton 6.21-GE 2 works ...

Qutebrowser handling xdg-open?

You can check the default application for MIME by running env XDG_UTILS_DEBUG_LEVEL=10 xdg-mime query default text/html (as stated in Arch wiki).

Based on this github issue, the qutebrowser desktop file is named as org.qutebrowser.qutebrowser.desktop, which can be found at ls /usr/share/applications/ | grep qutebrowser. Then to set qutebrowser as default browser we use xdg-settings, but we first need to unset the $BROWSER variable in bashrc (then set it again later). Then run xdg-settings set default-web-browser org.qutebrowser.qutebrowser.desktop and it is done.

Java LSP

Install jdtls first. If you use archlinux, then jdtls will be installed in /usr/share/java/jdtls. Then create the following script in a directory like /usr/local/bin/jdtls:

#!/usr/bin/env sh

# copy the configuration folder to tmp to be writable
tmp_dir="$(mktemp -d /tmp/jdtls.XXXXX)"
cp -R /usr/share/java/jdtls/config_linux "${tmp_dir}"
# and ensure that it is removed on exit
trap "{ rm -rf ${tmp_dir}; }" EXIT

server=/usr/share/java/jdtls #or whereever jdtls is installed at

java \
    -Declipse.application=org.eclipse.jdt.ls.core.id1 \
    -Dosgi.bundles.defaultStartLevel=4 \
    -Declipse.product=org.eclipse.jdt.ls.core.product \
    -noverify \
    -Xms1G \
    -jar $server/plugins/org.eclipse.equinox.launcher_1.*.jar \
    -configuration ${tmp_dir}/config_linux/ \
    "$@"

Then put this in vimrc:

let g:LanguageClient_serverCommands = {
    \ 'java': ['/usr/local/bin/jdtls', '-data', getcwd()],
    \ }

Then this should work!

Language client serverCommands autocmd/autogroup

If you want to source different .vim configs for different file types, you need to add BufReadPre, like:

au  BufReadPre,BufRead,BufEnter *.cpp source ~/.config/nvim/init_cpp.vim

This way g:LanguageClient_serverCommands will get sourced in before it starts so that the language client actually runs.

Wine audio laggy / glitching

Just try to tune it using the options here: https://forums.linuxmint.com/viewtopic.php?t=44862

Also according to the wiki, you also should add tsched=0 in the following in /etc/pulse/default.pa:

load-module module-udev-detect tsched=0

How to see how much memory a process is taking

You can get ps_mem (the github page) and see example usages.

For example, you can do sudo ps_mem -p $(pgrep -d, chromium) to see how much memory chromium is taking

Open links in Zathura issue

Maybe you have encountered a issue where you want to open links in zathura but xdg-open just fails you, and at the end you will get "no method available for opening" some link.

Firstly, you should set a BROWSER variable in your ~/.bashrc. I use chromium so I just did export BROWSER="chromium". Then this is not enough for some reason (you will know it if you run zathura again, at least for me it didn't work). You should also add the line set sandbox none in your zathurarc, usually located at ~/.config/zathura/zathurarc.

It might also be good to use xdg-setting to set the default web-browser like xdg-settings set default-web-browser chromium.desktop, as mentioned in the wiki

Emoji coverage

install the following font packages from pacman (I don't recall which package actually fixes the problem but just install these there is no harm):

noto-fonts-emoji

Maybe add the rest, but you don't really need it..

ttf-font-awesome
ttf-inconsolata
ttf-symbola
unicode-emoji

Disable mouse acceleration

Put this file in /etc/X11/xorg.conf.d/50-mouse-acceleration.conf:

Section "InputClass"
	Identifier "Logitech G403 Prodigy Gaming Mouse" #your mouse name
	MatchIsPointer "yes"
# set the following to 1 1 0 respectively to disable acceleration.
	#Option "AccelerationNumerator" "1"
	#Option "AccelerationDenominator" "1"
	#Option "AccelerationThreshold" "0"
	Option "AccelerationProfile" "-1"
	Option "AccelerationScheme" "none"
	Option "AccelSpeed" "-1"

Detecting Elantech trackpoint and touchpad

Append the following kernel parameters to /etc/default/grub, at GRUB_CMDLINE_LINUX_DEFAULT:

i8042.nomux=1 i8042.reset

So an example parameter will look something like

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet i8042.nomux=1 i8042.reset"

This should detect it... When you run dmesg you should be able to see that libinput recognizes the trackpoint and touchpad from /devices/platform/i8042/...

For example:

$ dmesg | grep -i trackpoint
[    2.522591] input: ETPS/2 Elantech TrackPoint as /devices/platform/i8042/serio1/input/input16
$ dmesg | grep -i touchpad
[    2.540001] input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio1/input/input8

Change trackpoint speed (especially after disabling mouse acceleration)

Based on https://wayland.freedesktop.org/libinput/doc/latest/device-quirks.html#installing-temporary-local-device-quirks, we need to create /etc/libinput/local-overrides.quirks file.

You can run xinput to see the available devices and their id. Then run xinput -list-props id and you can see which device node it is. In this example, the trackpoint is /dev/input/event14.

To see if any quirks are used, run sudo libinput quirks list /dev/input/event14. If nothing outputted, that means no quirks are used, which is often the case. To see the quirks libinput have tried, add --verbose argument, so run sudo libinput quirks list --verbose /dev/input/event14. Then you can see "Lenovo ... trackpoint" at 50-system-lenovo.quirks (just example name here). And if you go to /usr/share/libinput, you can open 50-system-lenovo.quirks to see the example config, but be sure to change the MatchName.

For example, when I run xinput I see that my trackpad is named ETPS/2 Elantech Touchpad, and the config does support wildecard, so you can do MatchName=*Elantech Touchpad. You can also change the AttrTrackpointMultiplier to modify the trackpoint speed.

Here is my config:

[Lenovo T495s Trackpoint]
MatchName=*Elantech TrackPoint
MatchDMIModalias=dmi:*svnLENOVO:*:pvrThinkPadT495s:*
AttrTrackpointMultiplier=2.6

AMDGPU

Put this file in /etc/X11/xorg.conf.d/20-amdgpu.conf:

Section "Device"
    Identifier  "AMD Graphics" 
    Driver      "amdgpu"
    Option      "Backlight"  "amdgpu_bl0"
EndSection
