I'll post here how I did to fix this problem. I had a nvidia gpu that died (black screen, no driver was working. system only loaded if there was no driver present). Now I am with a R9 270 and was having troubles installing the drivers. I couldn't install the catalyst crimson driver 15.12 because of this.
The error message was the following: vcdk is missing, installation aborted.
I did these on the recovery mode using two solutions.
Solution one: http://www.rage3d.com/board/showthread.php?t=33971086
I didn't know how to force the installer to use the command line so I found this help: http://community.linuxmint.com/tutorial/view/1176Hi all.
For all those that experience VCDK is missing error when installing cat 10.11 or older, there is a binding for library that is broken in the install routine when using the "X" Graphic version of the installer. The easy solution is to boot in to a terminal or use (crtl-alt F2) and force the installer to use the commandline version. There the broken binding is not appearing, and you can install the driver.
And that's it.The first thing we need to do is make sure that any old drivers are removed. The following commands will remove the old drivers.you may reciever errors its ok we are just making sure we remove all the old
-- sudo sh /usr/share/ati/fglrx-uninstall.sh
-- sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* xorg-driver-fglrx
Ok Now we are ready to start installing the driver
Go here and grab the driver you would like to use, for me this is the 12.11 beta do to the fact I use HDMI for sound.
Once the driver is downloaded, extract it. you should now have the driver in my case amd-driver-installer-12-1-x86.x86_64.run
Right click on the file go to properties then to permissions click the box “Allow executing file as program” close that window.
Open a Terminal and type sudo and drag and drop the driver in the terminal hit enter there will be a new window open pick the top option in the next 2 screens.
Now when it is done it will ask to reboot, DO NOT REBOOT YET. Just close the program.
In the terminal type sudo aticonfig --initial when aticonfig is done reboot.
After rebooting you should be running your new driver. You can type sudo amdcccle to run the catylist
I thank those that helped me to fix this today and if someone, in the future, find the solution here I'll be happy to have been useful somehow.
