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.
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):
After the latest updates from Ubuntu my system would not start the X server when booting up. I found a answer at askubuntu by the user darent (http://askubuntu.com/questions/399153/after-apt-get-upgrade-system-always-boot-to-low-graphics-mode):
I had this same problem just a few hours ago, the latest 331 is broken. Downgrading to the previous driver or any other, included the open-source nouveau won’t work, the only solution is uninstall all nvidia packages and install the driver from the .run you can download from the nvidia website.
There, select your graphic card, architecture, etc, and download the installer. When it’s done, you’ll need to install it from the command line without X running. Pres Ctrl+Alt+F1 and after login:
sudo service lightdm stop # (change this line to match the drivers you have installed # or simply sudo apt-get purge nvidia*). sudo apt-get remove nvidia-319 nvidia-331
Now, assuming your driver has been downloaded to the “Downloads” folder:
cd Downloads chmod +x NVIDIA* sudo ./NVIDIA*.run
I’ve used the asterisk here because I can’t know if the driver you downloaded is the exact same name as mine, since it depends on your GPU. You could use autocompletion with the tab key to use the exact .run name.
Follow the on screen instructions. When you finish, reboot:
sudo shutdown -r now
If after rebooting you see the same problem, log again in a TTY and try:
This should regenerate a new /etc/X11/xorg.conf
Just a quick update for anyone who used my solution: Today a new update of some gl libraries has broken my system again. I’ve had to re-install the NVIDIA run package, it complained about some of its libraries being altered and restored them to its working state. There seems to be a compatibility problem between libraries from the official repositories and the ones packaged in the driver. This is the reason I don’t like to install things from outside packagers… To reinstall the driver, kill the X with
sudo service lightdm stop
and reinstall the .run with
The installation of new NVIDIA drivers can be a problem sometimes, especially if you are not accustomed to the way things usually work on a Linux operating system.
There are just a couple of ways of installing the NVIDIA driver on an Ubuntu system: the easy way and the hard way. The easy way is also the most straightforward, but it requires a working Internet connection. This method will also introduce you to the beautiful world of PPAs.
Ubuntu 13.10, just like its predecessors, benefits from a large repository, but Canonical developers don’t upload the most recent version of the driver for several considerations. The most important is that it they don’t risk uploading a piece of software that has yet to be proven stable.
Fortunately, there is a PPA that makes available the latest versions of the drivers, a day or two after the launch. Just enter the following command in a terminal (you will need root access):
sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-331
If you already have an older version of the driver you will need to replace the last command with:
sudo apt-get dist-upgrade
After the process is finished, restart the computer and you’re set. The next time NVIDIA releases a new driver, you will only have to update the system, without adding the PPA.
The second method is a little more complicated, but you don’t need an Internet connection (you will need to download the driver at some point, but you don’t need the connection during the installation). We will be using the 64-bit driver as an example. I did not have a big success with this method
You will have to enter the virtual console with Ctrl + Alt + F1 and login into the system with the user name and password. There, you need to navigate to the location of your driver (for example Downloads) and enter the following commands
sudo service lightdm stop sudo chmod a+x NVIDIA-Linux-x86_64-331.20.run sudo ./NVIDIA-Linux-x86_64-331.20.run sudo reboot
This is it. Whatever method you choose, enjoy the latest NVIDIA drivers.
