Created attachment 1060227 [details] Xorg.0.log Here the requested Xorg.log procedure for this log was kill X (Cntrl+Alt+Backspace) changed setting to disable touchpad on connected mouse suspended the W530 (by closing the lid) resumed (by opening the lid) touched the touchpad
whoops, sorry about the delay here. The stack trace doesn't make any sense and suggests memory corruption elsewhere. Unfortunately with the NVIDIA driver in play here that makes it a lot harder to debug. do you still see the issue on the most recent versions?
