Cursor Jumping Problems

A problem I've been having whilst typing documents was the cursor was jumping all over the place. I'd be typing a paragraph and the cursor would appear in the middle of another line and my typing would appear in that point. Very annoying.

I finally realised what was happening. Xubuntu is installed on a Laptop and my fingers were brushing the touchpad thus moving the cursor. I've not had this when using Windows so don;t know why it happened in Xubuntu.

Fortunately I have found a solution by disabling the touch pad whilst typing. Here's how to do it:

In the menu select Settings > Setting manager. Select Mouse and Touchpad category.

Then select the Touchpad tab. then check Disable Touchpad when typing

Document Viewer will not open external links

A problem I recently came across whilst viewing a subscribed PDF magazine in the bundled document viewer was that I couldn't open external links getting the following error message:

Unable to open external linkFailed to execute child process "exo-open" (Permission denied)

The solution is to open a Terminal window and type the following:

sudo ln -s /etc/apparmor.d/usr.bin.evince /etc/apparmor.d/disable/usr.bin.evince

sudo service apparmor restart

Now all external links open fine in default browser.
