Installing Orange, openSUSE x64

 Old draft I never published:

Sadly, there aren't any binaries to install orange from.  In theory nightly builds are nice as you have the latest changes, however in practice, a lot can go wrong.

Download the nightly build (bottom of page) for linux
Extract the zip file.
follow the instructions for install listed here:
http://www.ailab.si/orange/installation_suse.html
caveots:
- the version of numpy and PyQwt need to be incremented to the verson you downloaded.
- when trying to run Orange Canvas, you will get an error "ImportError: No module named orange"
         -   create a blank file named __init__.py in the /usr/lib64/python2.6/site-packages/orange directory (this solution found here)


that fixes that error, but then you are stuck by:


 > python /usr/lib64/python2.6/site-packages/orange/OrangeCanvas/orngCanvas.pyw

Installing OpenSUSE on ASUS K55A

Burned and installed a copy of KDE OpenSUSE 11.4.


Things to prep for install:

Enter "BIOS" Setup (press <esc> during boot.

enable UEFI Compatibility Support Module 
disable Fast Boot Mode

Boot the CD/DVD in UEFI mode
Results:

Live CD seemed to work well, but I was unable to activate wirless.

Grub for UFEI worked!!

Wireless after install still did not work as the wireless adaptor seems to not have been detected.  Ended up installing Ubuntu, which worked great.

Installing Samsung Wifi Printer (CLP-315W) on OpenSUSE

Preamble
After getting up my Brother MFC all set-up I've found that the ink cartiges were empty despite a complete lack of use. Apparently the printer automatically flushes ink every so often to keep the print-heads from clogging. The idea of having to buy new ink 2ce a year when I hardly print really bothered me, so I decided it's time to make the move to laser.

As the rest of the Multifunction Brother is still in working order, I had trouble justifying the purchase of a brand new one with laser, the extra cost was the nail in the coffin. Further, as I checked prices, multi-function units with color were extremly expensive, so it only made sense that if I could find a network-able color laser printer for a reasonable price, I'd probably go with it.  With wireless networking and a $130 price tag, the Samsung CLP-315W was impossible not to bring home, despite my grudge against Samsung for it's poor (inexistent) linux support on it's multifunction printers.


Installation
Setting up the printer:
Setting up the printer was relatively easy, it only required removal of some packing tape, and plugging in the power cord and an ethernet cable into my router; the toner cartridges were already installed.
Activating wireless:
This was also simpler than I expected.  I have a hidden network and was worried that the printer might have trouble connecting to it.  After connecting your pinter via ethernet to your router (assuming your router automatically assigns IPs)

1. Find the printers IP via your routers interface page
2. Enter the IP into the address bar of your web browser
3. Click on the Network Settings tab and then the Wireless sub-tab
4. Enter your SSID and any access credentials.
5. Unlplug the ethernet cable

Installing the driver:
Forget about finding a RPM binary, the tar.gz-ed 'unified driver' download was also a breeze.   Assuming you are using KDE:

1. Navigate to the download folder and right click on the download.  
2. Choose "'Extract here, auto detect subfolder"
3. Click on the newly made "cdroot" folder
4. Open a terminal in this directory by pressing the F4 key
5. Execute the autorun shell script as root:

> sudo sh autorun

Answer the install scripts questions (press enter twice to accept defaults).  Use the closest numbered print driver: CLP-310splc

Adding the printer:

1. Lanch Yast (pres F2, type: yast).  
2. Click on the Hardware Icon then Printer.  
3. In the new window click the "Add" button.
4. In the new window click "Connection Wizard" button.
5. Under "Access Network Printer or Print Server via:" choose TCP port.
6. Enter your printers IP adress and brand, choose "test connection"
7. Click "Ok"
8. Under Assign Driver choose the CLP-310 driver and click "Ok"
9. Print a test Page

Calibrating the printer:

There may be a better (more uniform) way to do this described here (I haven't tried)

 Print the image above and verify

• the magenta, yellow, and cyan colors don't look washed out in the top of the image.
• if not you need to increase the amount of the washed out color
• the lightest levels of magenta, yellow, and cyan all appear to be equally filled.
• if not you should increase or decrease the color value in each channel as needed
• that you can see all of the black gradients.
• if not you should increase or decrease black as needed.
  

Changing color values:

1. Enter the IP address of your printer into the address bar of your web browser.
2. Click on "Machine Status"
3. Click on "Color"
4. Increase/Decrease the color of interest as needed.

Update
My router died and thus all network devices, including my printer were given new IPs (they weren't force-ably assigned in a logical manner before, and the new router doesn't seem to have the feature to set an IP based on MAC.

Stealing (forcing) an IP
As before you are going to have to either guess your printer's new IP or find it in your routers clients table if your address was previously being assigned by DHCP. Once you know this you can then force the IP of the printer to be what ever you want:  

1. Enter the IP address of your printer into the address bar of your web browser.
2. Click on the "Network Settings" tab
3. Click on "TCP/IP" in the left side bar
4. Increase/Decrease the color of interest as needed.

Pointing your computer to the new IP
Just follow the instructions under "adding the printer" above but delete the old printer before adding the new one.   Reboot before trying to send a test page (to properly reset the samsung utility).

Networked Brother Devices Including Multifunction Printer, Copier, Scanner, Fax

I have OpenSUSE boxes at home and work as well as networked Brother printers in both environments.  Therefore I thought it would be useful to document the install process.

Installing the printer drivers

1. Download both the lpr and cupswrapper drivers for each  Brother printer.
•  for MFC-7840W
• lpr
• cupswrapper
•  for HL-4040CN

•  for HL-4040CN
•  rpm  -ihv  --nodeps hl4040cnlpr-1.0.3-1.i386.rpm
2. Check to see if it's installed: rpm  -qa  |  grep  -e  (lpr-drivername) 
• for MFC-7840W (or any MFC printer)
•  rpm  -qa  |  grep  -e brmfc
• for HL-4040CN
•  rpm  -qa  |  grep  -e hl4040
3. Open your printcap file for editing (for non-network installs see here)
•  nano /etc/printcap
4. For each printer replace ":lp" line to the following 2 lines ( when done):

:rm=(ip address of your printer)\ :rp=lp\

Installing the cups driver

1. Set a root password for printing
• lppasswd -g sys -a root
2. Create a symlink from cups to lpd
• ln -s /etc/init.d/cups /etc/init.d/lpd
3.  Install the cups rpms:  rpm  -ihv  --nodeps  (cupswrapper-drivername)
•  for MFC-7840W
•  rpm  -ihv  --nodeps cupswrapperMFC7840W-2.0.2-1.i386.rpm
•  for HL-4040CN
•  rpm  -ihv  --nodeps hl4040cncupswrapper-1.0.3-1.i386.rpm
4.  Verify both lpr and cupswrapper drivers are installed: rpm  -qa  |  grep  -e  (lpr-drivername)  -e  (cupswrapper-drivername)
• for MFC-7840W (or any MFC printer)
•  rpm  -qa  |  grep  -e brmfc -e cupsw

Getting Prism working on OpenSUSE

The reason I updated OpenSUSE 11.1 to 11.2 was that with the update I hoped to get a new version of Firefox that would work with the Mozilla Prism plugin.  This was not the case, and after trying a few hacks surrounding the code the prism apps called (switching from Firefox to xulrunner) I still had no luck.  Finally I stumbled upon the fact that someone is kind enough to be maintaining a beta repository for Mozilla products at OpenSUSE.
http://download.opensuse.org/repositories/mozilla:/beta/

I added the repository via zypper

zypper ar http://download.opensuse.org/repositories/mozilla:/beta/openSUSE_11.2/mozilla:beta.repo

Then I installed Prism via YAST, and now Prism works like a charm!

Updateing from OpenSUSE 11.1 to 11.2

For a while I thought there was no straight upgrade path from OpenSUSE 11.1 to 11.2.  Indeed, when I first checked the opensuse.org website had told me that I must do a fresh install, or minimally do an update via a live CD due to compatiblity issues.  However, yesterday I was having some issues with Prism and decided to check again.    Here is what I learned.

• Upgrades are now fully supported: http://en.opensuse.org/Upgrade/Supported
  
• OpenSUSE has a program called "zypper" that is similar to debian's apt-get
• zypper reporsitories can be eaisly added / removed and updated

The process of updating consists of the following:

1. *Back up your /boot/grub/menu.lst file (not mentioned in the above link)
   
2. Check your sources and rename any repositories that will be updated
3. Disable all current repositories
   
4. Add the updated repository sources.
5. Refresh the repository list and download the latest version of zypper
   
6. Download all the packages before installing.
   
7. Install the new packages.
   

Zypper commands 

List your repositories

zypper ls -d

Changing the name of a generic repository (to keep for legacy purposes):

zypper renamerepo repo-oss 111-repo-oss

Disabling all repositories:

zypper modifyrepo --all --disable

Adding the new 11.2 repositories:

zypper addrepo --name "openSUSE-11.2 OSS" http://download.opensuse.org/distribution/11.2/repo/oss/ repo-oss
zypper addrepo --name "openSUSE-11.2 Non-OSS" http://download.opensuse.org/distribution/11.2/repo/non-oss/ repo-non-oss
zypper addrepo --name "openSUSE-11.2 Updates" http://download.opensuse.org/update/11.2/ repo-update

Adding other repositories (by url):

zypper ar  

Refresing the repositories:

zypper refresh 

Installing a single new package (new version of zypper)

zypper in zypper 

Downloading packages with out installing:

zypper dup -d

Installing all updated packages:

zypper dup

Problems I Encountered

KDM didn't launch after installing and restarting

I dealt with this by logging in as a normal user then at the prompt typeing the command:

startX

The Xserver crashed

as superuser I restored the old xconfig file:

sudo su 

mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bad

cp /etc/X11/xorg.conf.saxsave /etc/X11/xorg.conf

exit

then tried restarting X again

startX

KDE didn't work well on first run and the widgets had a tenancy to crash, so after playing around and ensuring that KDM was indeed installed, I restarted again and everything was much smoother.  Restarting was a bit tricky as it couldn't be done graphically or via sudo.  One had to actually log in as root to command a restart.

su

restart

At this point I noticed that my grub config file had been overwritten and I could no longer boot my other linux (Sidux) partition.  I had to restore using the menu.lst file on the Sidux partition, but that was a bit of a headache, hopefully the rest of you backed up your menu.lst file somewhere
