Thus I think I am not loading it. I just checked out <a href="show_bug.cgi?id=108085#c18">comment#18</a> and that made no difference, same problem. I just tested again for i915.enable_fbc=0 Still there but using the check that Daniel suggested looks like it is going wrong. [root@test tmp]# dmesg | grep -i "kernel command" [ 0.116842] Kernel command line: BOOT_IMAGE=/vmlinuz-4.20.5-200.fc29.x86_64 root=/dev/sda3 ro resume=/dev/sda2 i915.enable_fbc=0 rhgb quiet LANG=en_AU.UTF-8 [root@test tmp]# cat /sys/module/i915/parameters/enable_fbc 0 I thought I was setting the parameter correctly but it appears I am not. Suggestion? I certainly hope that once set correctly it fixes it because then we will all be happier.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
