1 - Compile and install driver:
Source: http://wiki.cchtml.com/
sudo aptitude install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++5 dkms
sh ati-driver-installer-9-6-x86.x86_64.run --buildpkg Ubuntu/jaunty
# i386
sudo dpkg -i xorg-driver-fglrx_*.deb fglrx-kernel-source_*.deb fglrx-amdcccle_*.deb
# AMD64
sudo dpkg -i xorg-driver-fglrx_*.deb fglrx-kernel-source_*.deb fglrx-amdcccle_*.deb

2 - Generate xorg.conf:
sudo aticonfig --initial=dual-head --screen-layout=right
sudo aticonfig --dtop=horizontal --overlay-on=1
sudo aticonfig --xinerama=on

Note: you can do “dpk-reconfigure xserver-xorg” to reset you xorg.conf to default values.

3 - Bug workaround:

  1. Login to a tty (ctrl+alt F1) and type sudo killall gdm.
  2. Type sudo nano (or gedit, whichever you prefer) /etc/ati/amdpcsdb to edit the file. Go to the [AMDPCSROOT/SYSTEM/DDX] section and add:
    EnableRandR12=Sfalse.
  3. Type this into a terminal, sudo nano (or gedit) /etc/X11/xorg.conf, to open the xorg.conf file.
  4. Under the “Device” section add these options on separate lines:
    Option "EnableRandR12" "false"
    Option "DesktopSetup" "horizontal"
  5. Now just restart your computer and it should be good to go.

Use DeltaCopy (as rsync server) on the Windows box:

http://www.aboutmyip.com/AboutMyXApp/DeltaCopy.jsp

You’ll need to open port TCT/873 in your windows firewall.

Note: To fix the accentuated characters issue in the filenames, you can replace the “Cygwin1.dll” in the DeltaCopy directory by a UTF-8 compliant Cygwin dll (http://www.okisoft.co.jp/esc/utf8-cygwin/). Then restart the service or reboot.

And here’s my bash script running on my Linux box (all the files are in a “backup-tools” directory):

#!/bin/bash
passwdfile=~ACCOUNT/backup-tools/passwd
excludefile=~ACCOUNT/backup-tools/exclude
options="--delete-after --recursive --exclude-from=$excludefile --human-readable --stats --times"
# This gives a  bored user something to watch
if [ "$1" = "--progress" ];
then
options=”$options –progress”
fi
echo “–starting–”
rsync OPTIONNALUSERNAME@SEVERADDRESS::DELTACOPYMODULENAME /WHERETOBACKUP –password-file=$passwdfile $options
echo “–done–”

Then I run it daily in the crontab (command “crontab -e”):

@daily ~ACCOUNT/backup-tools/rsync.sh | mail ACCOUNT -s "daily rsync result"

No more swap partition!

I am now installing Ubuntu without a swap partition and I use a swap file afterward.

Here’s the details from Ubuntu Swap FAQ:

Should I reinstall with more swap?

  • Definitely no.
  • With the 2.6 kernel, “a swap file is just as fast as a swap partition.”(Wikipedia:Paging, LKML).

How do I add more swap?

  • Usually, people associate swap with a swap partition, maybe because they’ve been proposed to create a swap partition on install. In fact any file can be used as a swapping device, be it a partition or a conventional file. If you’re considering responsiveness, my advice: add more RAM. Swapping to a partition or a file won’t change anything.
  • We will add more swap by adding a swap file.
  • Adding more swap is a four-step process :
    • a- Creating a file the size you want.
    • b- Formatting that file to create a swapping device.
    • c- Adding the swap to the running system.
    • d- Making the change permanent.
  • We will consider (as an example) a 512 M swap need.
  • a- Creating a file the size you want :
    • We will create a /mnt/512M.swap swap file.

      sudo dd if=/dev/zero of=/mnt/512M.swap bs=1M count=512

      • What is important here is count=512, which means we want our file to contain 512 blocks of bs=1M, which means block size = 1 MegaBytes.
      • Be careful *not* to do this dd of=/mnt/512M.swap bs=1M seek=512 count=0
        Though the file grows to 512M immediately,it will have holes that makes it unusable. 
  • b- Formatting that file to create a swapping device :

    sudo mkswap /mnt/512M.swap

  • c- Adding the swap to the running system :

    sudo swapon /mnt/512M.swap

    • You can see with “cat /proc/meminfo” that your additionnal swap is now available.
  • d- Making the change permanent :
    • edit your /etc/fstab:

      gksudo gedit /etc/fstab

    • and add this line at the end of the file:

      /mnt/512M.swap  none  swap  sw  0 0

    • save and reboot

rulesMy HTPC lack a graphical display. I want to see the play length of my movies, the temp of my CPU and the upload/download information of my torrents.

I first thought to purchase a VFD based display, but aren’t we after year 2000? Therefore, a greenish old style display is not really appealing.

But, I found what I needed at Matrix Orbital, a Canadian based company specialized in VFD AND LCD display.

They have a complete line of character USB display. And the all mighty Matrix Orbital GX Typhoon USB Graphic Display.
