https://bugs.freedesktop.org/show_bug.cgi?id=109150 Bug ID: 109150 Summary: "failed to set DRM interface version 1.4: Permission denied" after resume for lock screen. Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: libdrm Assignee: dri-devel@lists.freedesktop.org Reporter: nanericwang@gmail.com Created attachment 142890 --> https://bugs.freedesktop.org/attachment.cgi?id=142890&action=edit Xorg log before lock screen. Everytime after resume from a lock screen (monitor suspend), I see the following error from xorg log: [ 20.962] (II) xfree86: Adding drm device (/dev/dri/card0) [ 20.962] (EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied There is no such errors at first boot (before lock screen). My question: - How to know what is trying to access "/dev/dri/card0"? Where is the log? - Why it is trying to access "/dev/dri/card0", given that the xorg is started already? -- You are receiving this mail because: You are the assignee for the bug.
