Public bug reported: TL;DR: Double-check the indexing of radio buttons in the Additional Drivers dialog and how they correspond to installation actions, because there's something fishy going on.
I have a Radeon HD 6870, and on a fresh 13.04 install I wanted to install proprietary drivers for it. Found the "Additional Drivers" tab and had three choices which were, in order: xserver-xorg-video-ati, fglrx-updates, and fglrx. I selected fglrx-updates, hit "Apply Changes", and afterward confirmed with apt that it was installed. I rebooted, and all was fine. Later the same day, I wanted to revert to xserver-xorg-video-ati. I go into the dialog, select it, Apply Changes, and am decidedly unhappy to learn from apt that now fglrx-updates has been removed and replaced with fglrx instead of xserver-xorg-video-ati. The dialog still assured me that this was not the case. Seeing as fglrx was not installed, I told the dialog to install it. Afterwards, apt said fglrx-updates was installed again! So I told the dialog to install fglrx-updates, and finally both versions of fglrx are uninstalled and replaced by xserver- xorg-video-ati. At this point, the Additional Drivers dialog still happy thinks that fglrx-updates is installed. After a reboot, Additional Drivers agrees with apt that xserver-xorg- video-ati is what is installed. ** Affects: software-properties (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1222618 Title: Additional Driver choices don't always correspond correctly to installation actions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1222618/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
