Issue:

Solution:

1. Open the KDE System Settings app.
2. Click on "Shorcuts" line under the topic of Worskpace
3. On the Shortcuts pane, click on KWin in the Component pane.
4. In the search bar enter the word move followed by enter key.
5. The "Move Window" action should appear. Click on it.

Issue:

Trying to cast a Chrome web page (or chromecast enabled video) from Fedora 29 did not find any devices due to firewalld enabled.

Solution:

The following commands allow chromecast devices to be discovered without having to temporarily disable firewalld.

sudo firewall-cmd --get-active-zone
sudo firewall-cmd --permanent --zone=public --add-port=32768-61000/udp
sudo firewall-cmd --reload

Be sure to restart all versions the Chrome broswer. Be sure to kill any automatically started background instances of Chome.

Issue:

I do a lot of installing of Red Hat in a test environment without a RH subscription. I keep getting this error message:

# yum repo list
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
No such command: repo. Please use /usr/bin/yum --help

Today, after a yum update (I am at 7.6) and rebooting, I cannot run any yum commands without hanging. If I add the --noplugins option to the yum command, the yum command works. I need a more general solution short of removing subscription-manager via rpm command.

Web Sites

Configure NFSv3 and NFSv4 on CentOS 7

The following a good explanation of root_squash, no_root_squash and all_squash. All I know is that if root is to be able see data, no_root_squash needs to be specified in the /etc/exports line for the directory. https://computingforgeeks.com/configure-nfsv3-and-nfsv4-on-centos-7/

The following site is easy to follow but lacks in-depth information about the squashing. https://www.thegeekdiary.com/beginners-guide-to-nfs-in-centos-rhel/

Issue:

Launching a web site as a boarderless window in Google Chrome broswer can be done using 'More Tools -> Create Shortcut'. This works and gives an icon even but i have seen them break or go away. Sometimes they will launch in a boarderless window and sometimes not.

Solution:

Use the --app option when launching google-chrome command.

google-chrome --app=https://mail.google.gom

Of course, creating a launcher in a desktop would be preferred. Icons for desktops will need to be downloaded separately.
