dmesg of 3.19.1 kernel
I have reproduced this on another desktop computer with the same radeon card, if you need any more information I am more than willing to provide it. Might be related to this bug: https://bugzilla.kernel.org/show_bug.cgi?id=94171 Created attachment 114175 [details] [review] fix to test Please make sure your kernel has this patch: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=72edd83cc9e5819ed1ee771519143d7594e059f0 Then apply this kernel patch on top of it. Yes, that works! It now lights up (and works). I'm going to test it on another desktop computer. Tested on another computer, it is lighting up there aswell. Probably not related, but on the other computer if I enable both monitors, one of them is not updated. (With the exception of the mouse cursor). And if I only enable the DK2 it seems to work, but I think I see some corruption on some parts. From what I understand from you on irc is that it might not be related. So I will open a new bug report about that. Created attachment 115195 [details] [review] updated patch Can you try this patch as well? First reverified that it did not work with plain 4.0.0 vanilla kernel. Tested with 4.0.0 + updated.patch and it works. Just tried 4.0.3 vanilla (kernel.org) and it works (the patch seems to be upstream now). Closing as resolved + fixed. Thank you so much! |

Created attachment 114171 [details] xrandr --verbose after attaching DK2 and only enabling it on 3.19.1 (not lighting up) The DK2 does not light up on linux kernel 3.19.1 doing: xrandr --output HDMI-0 --auto --output DVI-0 --off --output DVI-1 --off It does light up doing exactly the same on 3.12.6 (xrandr --verbose attached). It does light up on 3.19.1 on *Intel* hardware.
