How to Make Scrollbar Always Visible in Ubuntu 18.04

Last updated: September 18, 2019

gnome shell

This quick tutorial shows how to make the scrollbars of GTK3 applications always visible, like Gnome terminal does, no matter whether the mouse cursor is moved over or not.

The scrollbar is only visible when the mouse cursor is moved mover in most of GTK3 applications. It will disappear in a few seconds once the cursor’s moved away.

On a per-app basis, you can start application by setting GTK_OVERLAY_SCROLLING=0 environment variable.

For example, open terminal (Ctrl+Alt+T) and run command to launch Gedit text editor:

GTK_OVERLAY_SCROLLING=0 gedit

To apply for all applications for current user, open terminal (Ctrl+Alt+T) and run command to edit .profile file:

gedit ~/.profile

When the files opens in text editor, add following 2 lines in the end and save the file.

export GTK_OVERLAY_SCROLLING=0
gdbus call --session --dest org.freedesktop.DBus --object-path /org/freedesktop/DBus --method org.freedesktop.DBus.UpdateActivationEnvironment '{"GTK_OVERLAY_SCROLLING": "0"}'

To apply changes, simply log out and login back.

To restore the changes, edit .profile file again and remove the previous lines.

How to Install Linux Kernel 5.3 in Ubuntu / Linux Mint

Last updated: September 16, 2019

Linux Kernel 5.3 was released yesterday. Linus Torvalds announced that:

So we’ve had a fairly quiet last week, but I think it was good that we ended up having that extra week and the final rc8.

Even if the reason for that extra week was my travel schedule rather than any pending issues, we ended up having a few good fixes come in, including some for some bad btrfs behavior. Yeah, there’s some unnecessary noise in there too (like the speling fixes), but we also had several last-minute reverts for things that caused issues.

One _particularly_ last-minute revert is the top-most commit (ignoring the version change itself) done just before the release, and while it’s very annoying, it’s perhaps also instructive.

…

Linux 5.3 kernel brings many exciting changes including initial Intel HDR display support, Intel Speed Select support, Radeon RX 5700 Navi series support, better Intel Icelake Gen 11 graphics support, ACRN guest hypervisor support.

How to Install Linux Kernel 5.3 in Ubuntu:

The mainline kernel packages for Linux 5.3 are available for download at the link below:

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-5.3.0-xxxxxx_all.deb
  2. linux-headers-5.3.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  3. linux-modules-5.3.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  4. linux-image-xxx-5.3.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):

For 64-bit OS:

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3/linux-headers-5.3.0-050300_5.3.0-050300.201909152230_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3/linux-image-unsigned-5.3.0-050300-generic_5.3.0-050300.201909152230_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3/linux-headers-5.3.0-050300-generic_5.3.0-050300.201909152230_i386.deb

How to Hide Files / Folders (Without Renaming) in Ubuntu 18.04

Last updated: September 13, 2019

This quick tip shows beginners how to hide files or folders, without renaming them, in Ubuntu’s default Nautilus file browser.

In Ubuntu Linux, a file (or folder) with a name starts by a dot (.) is considered a hidden file. Filename ends with a tilde (~) is considered backup file which is also hidden.

You can press Ctrl+H on keyboard to show or hide hidden files / folders in file browser.

To hide files and/or folders, without renaming them by prefixing dots (.) or suffixing tildes (~), you can use an extension called nautilus-hide.

NOTE following steps works for all current Ubuntu releases, though the title says for Ubuntu 18.04.

1.) Open terminal either by searching for “terminal” from application menu or by pressing Ctrl+Alt+T on keyboard.

When terminal opens, run command to install the extension:

sudo apt install nautilus-hide

2.) Then restart Nautilus either via reboot or by running command:

nautilus -q

Finally in Nautilus file browser, select ‘Hide Files’ in files’ context menu (right-click menu).

To un-hide them, press Ctrl+H to show hidden files, then either select “Unhide Files” in hidden files’ context menu or remove the .hidden file.

NOTE: The extension works by adding file or folder names, that you choose to hide, into .hidden file (auto-create if not exist). Nautilus reads that file to hide the listed files the next time you open or refresh the folder.
