--- Comment #14 from Kontantin Ivanov <kostyarin.ivanov at gmail.com> --- Content of the /lib/firmware/radeon copied manually from https://people.freedesktop.org/~agd5f/radeon_ucode/ I also tried xorg-edgers/ppa and oibaf/graphics-drivers ppa repositories. With xorg-edgers/ppa X server doesn't start. With oibaf/graphics-drivers nothing changed. When I used Xenial the `DRI_PRIME=1 glxgears` worked fine. But I can't remember after which update it broke. I can reinstall Xenial from scratch if need. -- You are receiving this mail because: You are watching the assignee of the bug.
