--- Comment #6 from Nick <nick.craig....@gmail.com> --- The problem was resolved by a reboot. As per the comment by Christoph Feck in comment 1 https://bugs.kde.org/show_bug.cgi?id=390334#c1 I had indeed tried to change Nvidia display drivers. In my case it appeared to have failed or at least nothing appeared to have happened which is why I didn't reboot. I used the additional drivers icon the upgrade from the 384 to the 390 driver but the dialog never updated e.g. the radio button remained on 384 when I rerun the additional drivers program... (from the command line /usr/bin/software-properties-gtk --open-tab=4. After the reboot the additional drivers program (/usr/bin/software-properties-gtk --open-tab=4.) and the 'Info Centre' program both showed the Nvidia 390 driver as selected. -- You are receiving this mail because: You are watching all bug changes.
