I just did a fresh install, because I messed my old one up. Now I can't change my graphics drivers from the noveau driver to the recommended one. Nothing happens when I click on "Apply". Reproducible: Always Steps to Reproduce: 1. Do a fresh Kubuntu install. 2. Try to change your graphics drivers. Actual Results: Still using the noveau driver. Expected Results: Switching to the recommended driver. My system also crashes every few minutes, so I'm hurrying typing this. Not sure if this is because of the driver.
I should probably mention that I had to do an offline install, because the installer didn't recognize my USB Wi-Fi adapter. This may have affected my ability to use the proprietary drivers. Should I file that as a bug, too?
After sudo apt-get update, some updates and restarts I was finally able to change the driver through the driver manager. Still, I think there needs to be done something: Either there should be a warning that offline-installations are not going to work fine or the process after the offline-installation should be improved. At the moment there is a notice that offline-installations are not a good idea, but I think there should be a warning. The updates need to get pulled immediately after starting the fresh installation for the first time, without having the user use the terminal. I know, sudo apt-get update is easy, but some users can't even do that.
As you have written: the updates fixed the problem. So the problem with switching the driver was fixed in an new version of something and doesn't need fixing. You also said that the updates should be pulled immediately after starting the fresh installation for the first time. This problem is a future request concerning a piece of software from Ubuntu. Please file a bug raport on their bug tracker: https://bugs.launchpad.net/ubuntu/ and mark the bug here as "RESOLVED: DOWNSTREAM"
