Fix Slow Boot “A start job is running …” in Ubuntu 18.04

Last updated: May 19, 2019

gnome shell

Ubuntu 18.04 is quite slow to boot up in my laptop in the last few days. It was stuck at the purple screen with Ubuntu logo in center for more than 1 minute before booting into the login screen.

When it was booting into the purple screen, press F2 to show the white and black text screen. There it told me that it was stuck at:

“A start job is running for dev-disk-by\x2uuid …(35s \ 1min 30s)”

To fix the problem, do following steps one by one:

UPDATE: First make a back up of /etc/fstab before editing the file by running command:

sudo cp /etc/fstab /etc/fstab-backup

1. Open terminal from application menu or by pressing Ctrl+Alt+T on keyboard. When it opens, run command:

sudo -H gedit /etc/fstab

Type user password (no asterisk feedback) when it prompts. It will open fstab (file system table) configuration file with gedit text editor.

2. When the file opens, you’ll see something look like this:

As the top picture shows, “UUID=1cdb9a5b-01a7-4b7b-a0ad-ce73676bb7c1”, mounting the Swap partition takes 1 minute and 30 seconds to boot up Ubuntu.

3. Launch Disks utility from application menu.

4. When it opens, check the Swap partition, and it obviously that the UUID value does not match the one in /etc/fstab.

5. So what I need to do here is to replace the UUID value with the correct one copied from Disks utility.

Finally, save the file and reboot.

Linux Kernel 5.1 Released! How to Install it in Ubuntu

Last updated: May 6, 2019

The latest stable Linux Kernel 5.1 was released. Linus Torvalds announced last night:

So it’s a bit later in the day than I usually do this, just because I was waffling about the release. Partly because I got some small pull requests today, but mostly just because I wasn’t looking forward to the timing of this upcoming 5.2 merge window.

…

On the whole, 5.1 looks very normal with just over 13k commits (plus another 1k+ if you count merges). Which is pretty much our normal size these days. No way to boil that down to a sane shortlog, with work all over.

…

Linux 5.1 brings many exciting changes including improved support for Intel Fastbook (enabled by default), Intel 22260 WiFi support, new I/O interface, new ACPI support, Raspberry Pi 3 Model A+ support by mainline, and a lot of new hardware support.

How to Install Linux Kernel 5.1 in Ubuntu:

The mainline kernel packages for Linux 5.1 are available for download at the link below:

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

  1. linux-headers-5.1.0-xxxxxx_all.deb
  2. linux-headers-5.1.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  3. linux-modules-5.1.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  4. linux-image-xxx-5.1.0-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 (Ctrl+Alt+T):

For 64-bit OS:

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-headers-5.1.0-050100_5.1.0-050100.201905052130_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-headers-5.1.0-050100-generic_5.1.0-050100.201905052130_i386.deb
