Description of problem: Xorg crash after suspend/resume when touching a disabled touchpad on a Thinkpad W530 Version-Release number of selected component (if applicable): xorg-x11-drv-synaptics-1.8.2-2.fc22.x86_64 How reproducible: suspend/resume a Thinkpad W530 running KDE and configure the touchpad to be disabled when a mouse is connected. Also a mouse has to be connected -> so the touchpad gets disabled. Steps to Reproduce: 1. Configure the touchpad to be disabled when a mouse is connected 2. Connect a mouse 3. suspend the W530 4. resume 5. touch the touchpad Actual results: Xorg crashes Expected results: no crash Additional info: If either there is no external mouse connected or the touchpad isn´t configured to be disabled when a mouse is connected everything works as expected Excerpt from /var/log/Xorg.0.log.old (EE) (EE) Backtrace: (EE) 0: /usr/libexec/Xorg (OsLookupColor+0x139) [0x59a489] (EE) 1: /lib64/libc.so.6 (__restore_rt+0x0) [0x33c3634a4f] (EE) 2: /usr/lib64/xorg/modules/input/synaptics_drv.so (_init+0xa479) [0x7f21add17af9] (EE) 3: /usr/lib64/xorg/modules/input/synaptics_drv.so (_init+0x4878) [0x7f21add0c5d8] (EE) 4: /usr/libexec/Xorg (DPMSSupported+0xe8) [0x478f98] (EE) 5: /usr/libexec/Xorg (xf86SerialModemClearBits+0x2b2) [0x4a25b2] (EE) 6: /lib64/libc.so.6 (__restore_rt+0x0) [0x33c3634a4f] (EE) 7: /lib64/libc.so.6 (__select_nocancel+0xa) [0x33c36f903a] (EE) 8: /usr/libexec/Xorg (WaitForSomething+0x1d0) [0x593380] (EE) 9: /usr/libexec/Xorg (SendErrorToClient+0x111) [0x43a311] (EE) 10: /usr/libexec/Xorg (remove_fs_handlers+0x41b) [0x43e5fb] (EE) 11: /lib64/libc.so.6 (__libc_start_main+0xf0) [0x33c3620700] (EE) 12: /usr/libexec/Xorg (_start+0x29) [0x4289c9] (EE) 13: ?

:: whot@jelly:~> eu-addr2line -e /usr/lib64/xorg/modules/input/synaptics_drv.so _init+0xa479 /usr/src/debug/xf86-input-synaptics-1.8.2/src/eventcomm.c:632 which suggests that priv->proto_data is NULL, which is odd. Please attach your full Xorg.log from that crash.
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?
