I can confirm this. I had this exact same issue (with an intel HD530 card). The fix mentioned above worked.
The incorrect response from xdriinfo also seems to have caused issues with several other programs (such as steam play games and video playback) that now seem to be fixed. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to x11-utils in Ubuntu. https://bugs.launchpad.net/bugs/1787845 Title: Broken xdriinfo on Ubuntu 18.04 breaks driconf Status in x11-utils package in Ubuntu: New Bug description: driconf doesn't work on Ubuntu 18.04. The reason is that xdriinfo fails with "Screen 0: not direct rendering capable." There appears to be a fix for this upstream: https://cgit.freedesktop.org/xorg/app/xdriinfo/commit/?id=6273d9dacbf165331c21bcda5a8945c8931d87b8 Building my own xdriinfo from the upstream source code fixed the problem for me. Please consider updating xdriinfo for Ubuntu 18.04 to unbreak driconf.
