It works!!!

For some time have I had problems running Kububtu and 3 monitors at the same time on a Nvidia card.

I solved by having each monitor running on each own xserver. That worked fine but certain things where not optimal.

I could only change display configuration by using Nvidia setting and I couldn’t disable the screen saver. Not a big problem but when I was watching TV suddenly I would miss a coal because of the screen saver.

I also have a Wacom tablet. It isn’t very often I use it but the other day there were a question at Ask Ububtu about pressure sensibility and I wanted to the answer question.
I just wanted to test if everything was working fine and to my surprise it was not.

Again I did the BIG investigation and hours went by. I could not the get pressure sensibility to work.

Even Krita wouldn’t work at all with the tablet.

So in the end I tried to remove (rename) the /etc/X11/xorg.conf file and reboot.

As the computer was rebooting I was getting grumpy because I suspected the X configuration was the problem and I could not get the 3 monitors to work at the same time.

But Kubuntu booted up, X started and everything looked normal, YES! It works now.
I Just had to goto the Diaplay and Monitor settings and configure the display order to my needs.

Was I one happy little boy and the grumpiness was gone 🙂

I suspect the problem is solved in KDE ver. 4.13.2

To install on Kubuntu add to the repository search:

ppa:kubuntu-ppa/backports

Or, from a command line:

sudo add-apt-repository ppa:kubuntu-ppa/backports

Then

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

Hope you will enjoy!

Kubuntu 14.04 LTE

I just upgraded to Kubuntu 14.04 LTE.

The previous version was 13.10 upgraded from 13.04.
The upgade was a walk in the park without any problems.
I had I minor issue with the displays had to be reordered (I have 3 monitors connected).
My left most monitor was moved to the middel but running the nvidia-settings solved the problem.
Else everything works as expected. I havn’t found any other issues yet.

Installing Aftershot Pro on Kubuntu 64-bit

Yet another problem when I installed Aftershot Pro on Kubuntu 13.10 64-bit.

I happily downloaded Aftershot Pro 64-bit installation package from Corel’s site and tried to install it by:

$> sudo dpkg -i AfterShotPro_amd64.deb

The package manager complained about ia32-libs was not installed.
I looked all over to find out how to install the ia32-libs lib on 64-bit but all solutions failed.

Then I stumbled over a forum thread asking the stupid question:

"Why not install the 32-bit version?" 

and the answer from the user was:

"It worked, thanks a lot!"

To install the 32-bit version of Aftershot Pro on 64-bit Kubuntu you have to run the command:

$> sudo dpkg -i --force-architecture ./AfterShotPro_i386.deb

You also have to do the same for all updates.

Yet another problem to be solved…

I have 3 monitors attached to my graphics card, a Nvidia 650ti, and in my new installation everything seemed to working fine except the screen saver.

When the screen saver was activated then 2 monitors was flashing on and off and the last monitor on the HDMI connection was turned off and would not get alive when it went of screen saver mode.

I found out when I configured the graphic card to use separate X screens the problem was solved.

To do that:

1. Start the nvidia-settings and under 
   "X Server Display Configuration"->Configuration 
2. select "Separate X screen (requieres X restart)" 
3. Also Enable Xinerama under "X Server Display Configuration"

You can’t just apply these setting and you will have to save it in “/etc/X11/xorg.conf” configuration file and restart the X-server.

If you don’t have xorg.xonf file then one can be generated by running:

$> sudo nvidia-xconfig

I prefer to reboot after this change but it can also be done by restarting the X-server.
On Kubuntu (save everything as your session will be killed):

$> sudo service lightdm restart.

Now once the X-server is restarted you might have the same problem as I do: Only English keyboard layout.

The can be fixed by either change the xorg.conf file or by running the command:

$> setxkbmap -model pc105 -layout dk,us -option grp:alt_shift_toggle

This will setup a 105pc keyboard and have both Danish (dk) and American (us) keyboard layout and to change between the 2 press the <Alt> and <Shift> simultaneously.

This will of cause be reset every time the computer reboot so I added the command to (if you are running KDE as on Kbuntu):

/home/<user name>/.kde/env/setlocale.sh
