** Description changed: + [Impact] + The lts-wily backported kernel introduces the amdgpu driver. Graphics cards that use this driver need the render node (/dev/dri/renderD*) to be accessible to users. + + [Test Case] + Install the lts-wily kernel, and check whether /dev/dri/renderD* is accessible or not. + + [Regression Potential] + Low, as the change is already upstream and included in wily. + + -------------------------------- 3.16/3.19 Linux kernel add render node support which will create /dev/dri/renderD*. uaccess tag must be added to the /lib/udev/rules.d/70-uaccess.rules to make it access-able to login user just like /dev/dri/card*. It has been done on Ubuntu 15.04, but 14.04.3 has not. 14.04.3 70-uaccess.rules # DRI video devices SUBSYSTEM=="drm", KERNEL=="card*", TAG+="uaccess" 15.04 70-uaccess.rules # DRI video devices SUBSYSTEM=="drm", KERNEL=="card*|renderD*", TAG+="uaccess" Please fix this for AMD GPU driver will use the /dev/dri/renderD*.
