In the driver manager of Kubuntu: It looks like pressing "OK" was the same as pressing "Cancel".

[Ganton]

Dear Sirs:

I have a virtual machine with Kubuntu 15.04 beta 2, and there the driver manager warned that there were two drivers that could be updated (I attached a screenshot to this bug report). I selected those drivers that could be updated, I pressed OK and... the window closed, and no driver was installed.

To install those drivers I had to: go to the driver manager, do it all again, but this time instead of "OK" I pressed "Apply".

So, in the driver manager of Kubuntu: It looks like pressing "OK" was the same as pressing "Cancel". Pressing "OK" should have installed all the drivers that were selected.

All in all, the new Kubuntu is very good! Thanks for Kubuntu!

Status changed to 'Confirmed' because the bug affects multiple users.

I am currently running into this same issue on a fresh install of Kubuntu 14.04.

The driver manager lets me choose between three video drivers (fglrx, fglrx-updates, and xserver-xorg-video-ati). If I can pick one of them and click "OK", the window immediately closes and nothing changes. If I click "Apply" instead, some message on a red background (presumably an error message) flashes very briefly, without letting me enough time to read it, then the manager goes back to the "collecting information" phase.

I tried running "/usr/bin/kcmshell4 kcm_driver_manager" in a terminal to get more useful output, and this is all I got:

The problems still exist in Kubuntu 16.04 LTS beta2.

This should not be difficult to fix?

Another problem that maybe is related:
Later, in a Virtualbox virtual machine, when executing `usr/bin/kcmshell5 kcm_driver_manager`, it's seen in the command line:
     pci id for fd 67: 80ee:beef, driver (null)
     libGL error: core dri or dri2 extension not found
     libGL error: failed to load driver: vboxvideo
and the driver manager stays saying "Collecting information about your system" forever.

Thanks for Kubuntu!
