--- Comment #12 from Eugene Shalygin <eugene.shalygin+bugzilla.FDO at gmail.com> --- Without the option, the message is not shown, but the HDMI screen is unusable: every second or third frame is shown shifted by approx. 50 pixels downward. When the screen is connected before boot, it is recognized always, but it does not work every time when hot-plugged. So, in my case radeon.hw_i2c=1 seems to be required option. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
