Firefox is started automatically but it looks corrupted

September 28, 2014 Leave a comment

Problem
On my home desktop I have autologin enabled, i.e. I don’t need to log in manually. Since I always need a terminal and a browser, “konsole” and “firefox” are started automatically. So I just switch on my machine and when I come back 5 minutes later, I’m ready to work.

However, sometimes Firefox doesn’t start normally. It looks strange: some colors are replaced with a different one, fonts are different, tooltips on tabs are plain black (text in tooltips is not visible), etc. If I restart Firefox, it becomes OK. I’m not sure what causes this problem, but my guess is that Firefox is started too quickly. I think it would require some libraries that are not yet loaded when Firefox is started. Then these pieces of software are loaded, that’s why Firefox gets OK after a restart.

Solution
The solution is simple. Don’t start Firefox immediately after the login. Wait some time until everything else is loaded, and start it after. Of course, we still want to start Firefox automatically, not manually. So we need a simple script:

#!/usr/bin/env bash

# /home/jabba/bin/start_firefox.sh
sleep 60    # Wait 60 seconds. You can play with this value.
/usr/bin/firefox &

Then in the Startup Applications, remove “firefox” and add this script instead. Provide the absolute path of the script. Make sure it’s executable. Here is a screenshot of the applications that are started automatically on my machine:

Launch gedit in the background

September 11, 2014 1 comment

Problem
Sometimes I use gedit but it is launched in the foreground, blocking my terminal. There are two ways to put it in the background: (1) Press CTRL+Z in the terminal, then send the job to the background with the command bg, or (2) launch gedit directly in the background with the “&” sign.

Neither of them is convenient. I often forget about it and I always end up in a blocked terminal. I just simply want to write “gedit” or “gedit ehh.txt“, and I want it to start in the background.

Solution
Create a script called “gedit” in your $HOME/bin directory with the following content:

/usr/bin/gedit "$@" &

Make it executable and make sure the directory $HOME/bin is in your PATH.

Windows 8.1 with Linux

September 4, 2014 Leave a comment

I got a new laptop at my workplace, a Toshiba Satellite C55. I decided to put Windows 8.1 and Ubuntu 14.04 LTS on it.

Installation
I had a Windows 8.1 ISO but I didn’t want to burn it on a DVD. Instead, I put it on a USB stick. I found an excellent tool called Rufus that allows you to create a bootable USB stick from an ISO file. Here is a youtube video tutorial too.

When Windows 8.1 was installed, the next step was to install Ubuntu. Restarting Windows is tricky if you want to change the boot order: hold down the SHIFT key and select reboot while pressing the SHIFT. Upon reboot I had to press F12 to get to the boot order menu.

Installation of Ubuntu went flawlessly.

NTFS partitions cannot be mounted
Once I had a strange problem. Ubuntu started to complain that it cannot mount the Windows partitions. It turned out that Windows was hibernated and thus the NTFS paprtitions cannot be mounted in read/write mode. But why is it hibernated when I restarted Windows?

Well, another “cool feature” of Windows 8.1 is that you can power it off / restart it in two different ways! Option 1: right click on the Windows button in the bottom left corner and select halt / restart. This will do some hibernation, thus the next boot will be faster. Option 2: move the mouse to the bottom right corner, wait for the tiles to show up and halt / restart the machine there. It is a normal power off / reboot without any hidden hibernation.

So, if you use Linux with Windows 8.1 in dual boot, you’d better stop / restart Windows using Option 2 (on the right side).

machine shuts down, then restarts in a few seconds

July 11, 2014 Leave a comment

Problem
My new desktop machine has a strange behaviour. It shuts down normally, but after a few seconds it restarts automatically.

Solution
I found the solution here. In short:

Edit the file “/etc/default/grub” and modify this line:

GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet splash"

The new thing is the “acpi=noirq” part. Don’t forget to run “sudo update-grub” at the end.

It solved the problem but when I hit the SPACE button on the keyboard, the machine wakes up as if I had pressed the power button. Strange, but maybe it’s normal for new machines.

open links in okular with Firefox

July 10, 2014 Leave a comment

Problem
You have a PDF that contains links. You click on a link but it opens in a strange browser (Konqueror?). How to open links with Firefox?

Solution

  1. Run the command “kcmshell4 filetypes“. File Associations – KDE Control Module will open.
  2. Search for html and select the file type text/html.
  3. Move the application name you want to be a default for html in the “Application Preference Order” to the top.

I copied this solution from here. Credits go to djhurio.

installing new fonts

Problem
You have a new font that you want to install system-wide. For instance, you copy some *.ttf fonts from a Windows machine (from C:\Windows\Fonts\) and you want to use them.

Solution
Install font-manager:

sudo apt-get install font-manager

With this software you can also browse your fonts. To install a new font, click on the Manage fonts icon in the bottom left corner next to the Save icon.

Tip from here.
