Ever since the removal of the catalyst driver and replacement with the Xorg amdgpu driver at least 6 months ago, shortly after the kernel loads and detects hardware the screen blanks, the keyboard doesn't respond, although numlock and capslock are working, but any of the alt+ctl or reisub commands won't work, however the system does continue to load in the background. I suppose this occurs when kernel mode setting kicks in. I can only get a working screen using nomodeset in the command line, which limits me to an 800x600 fb screen. AMD support tells me there is no support for R6 graphics in amdgpu pro, but an Xorg support person tells me that their Xorg version of amdgpu (not pro) does support this carrizo chipset. I've tried the latest Xorg amdgpu to no avail. Apparently, the basic Xorg.ati driver won't work with this chipset. I even get conflicting accounts of how to set up this card with the vesa driver! I haven't been able to achieve it and I'm a 24 year Linux user! I've tried this with all kernels since 4.3 and am now running 4.8.11 and the problem remains. BTW I run PClinuxos with KDE. Is this even a bug or just an unusual configuration issue? I don't have the amdgpu driver installed at the moment, but here are my dmesg and Xorg.log files.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
