    What happens in Manjaro if you start the patch script with:
    sudo ./PatchVivaldi.sh ~/VivaldiPatch

  • @gwen-dragon Ah, thanks...

    [steffie@Tower etc]$ sudo cat /etc/sudoers
[sudo] password for steffie: 
## sudoers file.
##
## This file MUST be edited with the 'visudo' command as root.
## Failure to use 'visudo' may result in syntax or file permission errors
## that prevent sudo from running.
##
## See the sudoers man page for the details on how to write a sudoers file.
##

##
## Host alias specification
##
## Groups of machines. These may include host names (optionally with wildcards),
## IP addresses, network numbers or netgroups.
# Host_Alias    WEBSERVERS = www1, www2, www3

##
## User alias specification
##
## Groups of users.  These may consist of user names, uids, Unix groups,
## or netgroups.
# User_Alias    ADMINS = millert, dowdy, mikef

##
## Cmnd alias specification
##
## Groups of commands.  Often used to group related commands together.
# Cmnd_Alias    PROCESSES = /usr/bin/nice, /bin/kill, /usr/bin/renice, \
#                           /usr/bin/pkill, /usr/bin/top
# Cmnd_Alias    REBOOT = /sbin/halt, /sbin/reboot, /sbin/poweroff

##
## Defaults specification
##
## You may wish to keep some of the following environment variables
## when running commands via sudo.
##
## Locale settings
# Defaults env_keep += "LANG LANGUAGE LINGUAS LC_* _XKB_CHARSET"
##
## Run X applications through sudo; HOME is used to find the
## .Xauthority file.  Note that other programs use HOME to find   
## configuration files and this may lead to privilege escalation!
# Defaults env_keep += "HOME"
##
## X11 resource path settings
# Defaults env_keep += "XAPPLRESDIR XFILESEARCHPATH XUSERFILESEARCHPATH"
##
## Desktop path settings
# Defaults env_keep += "QTDIR KDEDIR"
##
## Allow sudo-run commands to inherit the callers' ConsoleKit session
# Defaults env_keep += "XDG_SESSION_COOKIE"
##
## Uncomment to enable special input methods.  Care should be taken as
## this may allow users to subvert the command being run via sudo.
# Defaults env_keep += "XMODIFIERS GTK_IM_MODULE QT_IM_MODULE QT_IM_SWITCHER"
##
## Uncomment to use a hard-coded PATH instead of the user's to find commands
# Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
##
## Uncomment to send mail if the user does not enter the correct password.
# Defaults mail_badpass
##
## Uncomment to enable logging of a command's output, except for
## sudoreplay and reboot.  Use sudoreplay to play back logged sessions.
# Defaults log_output
# Defaults!/usr/bin/sudoreplay !log_output
# Defaults!/usr/local/bin/sudoreplay !log_output
# Defaults!REBOOT !log_output

##
## Runas alias specification
##

##
## User privilege specification
##
root ALL=(ALL) ALL

## Uncomment to allow members of group wheel to execute any command
# %wheel ALL=(ALL) ALL

## Same thing without a password
# %wheel ALL=(ALL) NOPASSWD: ALL

## Uncomment to allow members of group sudo to execute any command
# %sudo ALL=(ALL) ALL

## Uncomment to allow any user to run sudo if they know the password
## of the user they are running the command as (root by default).
# Defaults targetpw  # Ask for the password of the target user
# ALL ALL=(ALL) ALL  # WARNING: only use this together with 'Defaults targetpw'

    I guess sudo has a bug in Manjaro or special default setting which does not pass the callers $HOME variable.
    A quick search in web showed me some issues for program sudo, but i did not investigate more (missing spare time)!

    You can see what sudo allows for users with:
    sudo -l -U username

    missing spare time

    ... yes, sorry to have stolen it from you ... many thanks for your generosity.

    [steffie@Tower ~]$ sudo -l -U steffie
[sudo] password for steffie: 
User steffie may run the following commands on Tower:
    (ALL) ALL
[steffie@Tower ~]$

    Anyway, i'm extremely happy with this outcome Lilo. Running your script in future with that simple little extra bit is easy & works great.

    Now, get back to work, you idler !!! 😉

  • Hier mal wie sich sudo su und sudo -i unter manjaro verhalten.

       [ 14:29 ]  [ rolf@hongkong:~ ]
   $ sudo -i
   [hongkong ~]# pwd
   /root
   [hongkong ~]# Abgemeldet
   [ 14:29 ]  [ rolf@hongkong:~ ]
   $ sudo su
   [hongkong rolf]# pwd
   /home/rolf

    sprich sudo -i wird unter manjaro nicht funktionieren.

    @rocknrolf Do you know why $HOME of caller is not passed to bash script on Manjaro after sudo?
    Has Manjaro some special Default env_* settings in sudoers?

    No the sudoers file seems to be "normal".

    @rocknrolf Perhaps some changes in sudo cause this: See https://www.sudo.ws/stable.html

    Hello guys, just wanted to share a new version I did of this script. I uploaded this together with my custom.js and custom.css to a repo in https://github.com/gregodadone/vivaldi-simple-ui. Special thanks to @Gwen-Dragon and @Christoph142 because I used your ideas to create it. Feel free to modify as you want or make suggestions to make it better.
