How to Fix Ugly Japanese Fonts in Firefox

May 11, 2012 in Applications, Firefox, Linux, Ubuntu | 1 comment

The other day I took and reinstalled Ubuntu on my computer. So now I’m running 12.04, and I have to say that it’s a really nice OS.

Anyway, in Firefox I encountered an ugly Japanese font on some pages. It looked like an old/jagged serif font. However, on some other pages it looked much better and modern.

After looking around I finally managed to fix that ugly font problem by doing these steps:

  1. Open Firefox’s Preferences window.
  2. Select the Content tab.
  3. Click on the “Advanced…” button under “Fonts & Colors”.
  4. A new window appears with the title Fonts.
  5. Select Japanese in the “Fonts for:” drop-down list.
  6. Select “sans-serif” in the “Serif:” drop-down list.
  7. Finally close the window by clicking the OK button and you are done.

How to Fix Power/Battery Problem with Linux Kernel 3.x on Ubuntu 11.10

November 16, 2011 in Linux, Ubuntu | 6 comments

I have installed Ubuntu 11.10 on my laptop but I noticed that it drained a lot more of the battery than it should do. Apparently there are a couple of fixes to this:

To add pcie_aspm=force, i915.i915_enable_rc6=1, i915.i915_enable_fbc=1 and i915.lvds_downclock=1 to GRUB, do the following steps:

  1. Open the terminal and run: sudo gedit /etc/default/grub
  2. Add:
    pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1
    to
    GRUB_CMDLINE_LINUX_DEFAULT=”",
    so it should look somewhat like:
    GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1″
  3. Close gedit and save the document.
  4. Now run the following line in the terminal to update GRUB:
    sudo grub-mkconfig -o /boot/grub/grub.cfg
  5. After a restart of your computer the new settings should get activated.

Why Aptitude Is Superior To Apt-Get

May 14, 2011 in Linux, Ubuntu | 2 comments

Yesterday I was messing around in the terminal and googeling for cool and useful commands. I had seen the command aptitude being mentioned a few times before in forum threads and such, but I had never tried to use it myself. However, yesterday I did try use it didn’t take long time until I realised how superior it’s to apt-get.

Instead of ranting about what it does better than the other myself, I will link to an article from 2007 that describes everything very well:

Ubunchu! – The Very Best Manga

May 13, 2011 in Linux, Manga, Ubuntu | No comments

Ubunchu!The other day I found a really great manga when I was searching for an anime character on Google. It’s called Ubunchu! and it’s about, as the name suggest, Ubuntu! :)

The story is about the SysAdmin club on a Japanese school, and it starts out with the club’s three only members deciding what operating system to install on their computer. They agree to try out Ubuntu, and the following chapters are about different Ubuntu and Linux stuff. Like one chapters is about the terminal and how you use commands, and another one is about how you use the forums to get help.

Check it out, it’s really great I must say!

Black Screen After Installing FGLRX In Linux Mint

May 6, 2011 in Hardware, Linux, Ubuntu | No comments

I have finally bought a new graphics card to my computer, a Asus Radeon HD 6870 DirectCU. It was a bit longer than my old card, a PowerColor 4870, so it was tough to fit in the computer chassis. But I made it at last. :) The reason why I purchased a new card, was because my old one was half broken and wasn’t able to run with the default clock speeds without getting artifacts everywhere on my monitors.

When I first started Linux Mint with my new card plugged in, I was welcomed by a black screen, which wasn’t very fun. So I booted up Linux Mint in Recovery Mode and tried to install working graphics driver. The driver I had from earlier was ATI/AMD proprietary FGLRX graphics driver from the Additional Drivers window in Linux Mint (and Ubuntu). This graphics driver didn’t work after a clean install of Linux Mint either.

I also found these two guides: https://help.ubuntu.com/community/BinaryDriverHowto/ATI and http://wiki.cchtml.com/index.php/Ubuntu_Maverick_Installation_Guide, which describes how to install ATI driver. But the terminal command aticonfig never worked for me, so I didn’t manage to complete the installation.

However, if you simply download the proper driver from AMD’s website, and then run it like a normal program, it works just as it should. So I can’t really see the reason why you would build the graphics driver into packages and install them and so on in 20+ steps. Maybe it’s easier to uninstall the driver in the future. But how often do you change video card or update your graphics driver on Linux?

Anyway, it works great now and I’m happy.

Install Gens/GS (Megadrive Emulator) On 64-bit Ubuntu

May 1, 2011 in Applications, Games, Linux, Ubuntu | 5 comments

Sometimes I download and listen to Retroresan, which is a Swedish podcast about retro games. Recently they talked about the game Disney’s Aladdin to Megadrive, and it sounded pretty fun. So I searched and found a emulator called Gens/OS that seems to work great on Ubuntu 11.04 64-bit. However, it isn’t made for 64-bit OS:es, but it runs fine if you force install it. Here are the steps you have to take:

  1. Visit http://segaretro.org/Gens/GS, scroll to the bottom of the page and download the most recent version to Ubuntu.
  2. Make sure you have ia32-libs installed by typing these commands in the terminal: 
    sudo apt-get update
sudo apt-get install ia32-libs
  3. Then navigate to your downloads folder in the terminal, and type this line to install Gens/GS: 
    sudo dpkg --force-architecture -i gens_2.XXX_i386.deb
  4. Now the emulator should pop up under your Games category.

Here follows some links:

Ubuntu Shell Script to Enable and Disable Secondary Monitor

April 22, 2011 in Linux, Ubuntu | 5 comments

I wrote a short, simple shell script to easily enable and disable my secondary monitor in Ubuntu. I have saved it as monitor.sh in my home folder, and here is the source code:

#!/bin/sh
echo "Turn on: 1\nTurn off: 2"
read option
if [ $option = 1 ];
then xrandr --output DFP2 --auto --left-of DFP1
elif [ $option = 2 ];
then xrandr --output DFP2 --off
fi

To run it, just open a terminal window (Ctrl + Alt + T) and type sh monitor.sh. If you are really lazy, you can add an alias for the command in the file .bashrc in your home folder. I named my alias m. :)

  1. Open a new tab.
  2. Type about:config in the address bar.

  7. Done!
