Do attach Xorg.log > and/or relevant section of dmesg/journalctl. My apologies - this may not be the exact same bug. However, since I was seeing the same stack trace from Xorg (see below) I assumed it was. Issue I'm having is that when I connect my laptop to my docking station with external monitor, I receive the same Xorg crash as the other person. (Intel driver crashes with the below stack trace.) I actually don't know if the monitor or the docking station is displaylink or not. (Monitor is Samsung u28e590d; dock is Dell e-port replicator.) However, downgrading from Mesa 13 to 12 does fix the issue. And the upgrade to libdrm 2.4.72 didn't fix it. --- Stack trace: [ 6496.994] (II) intel(0): Enabled output DP1-1 [ 6497.010] (II) intel(0): Enabled output DP1-2 [ 6497.011] (II) intel(0): Enabled output DP1-3 [ 6497.058] (--) intel(0): HDMI max TMDS frequency 300000KHz [ 6497.061] (EE) [ 6497.061] (EE) Backtrace: [ 6497.061] (EE) 0: /usr/lib/xorg-server/Xorg (OsLookupColor+0x139) [0x59cd49] [ 6497.065] (EE) 1: /usr/lib/libc.so.6 (__restore_rt+0x0) [0x7f2d13c670af] [ 6497.066] (EE) 2: /usr/lib/libc.so.6 (readdir+0x29) [0x7f2d13ce77e9] [ 6497.067] (EE) 3: /usr/lib/xorg/modules/drivers/intel_drv.so (_init+0x63998) [0x7f2d0f2dd728] [ 6497.068] (EE) 4: /usr/lib/xorg/modules/drivers/intel_drv.so (_init+0x662b3) [0x7f2d0f2e3103] [ 6497.069] (EE) 5: /usr/lib/xorg/modules/drivers/intel_drv.so (_init+0x6d985) [0x7f2d0f2f1fb5] [ 6497.069] (EE) 6: /usr/lib/xorg-server/Xorg (xf86Wakeup+0x197) [0x479697] [ 6497.069] (EE) 7: /usr/lib/xorg-server/Xorg (WakeupHandler+0x6d) [0x43b2dd] [ 6497.070] (EE) 8: /usr/lib/xorg-server/Xorg (WaitForSomething+0x1e9) [0x5954f9] [ 6497.070] (EE) 9: /usr/lib/xorg-server/Xorg (SendErrorToClient+0x10e) [0x4365ee] [ 6497.070] (EE) 10: /usr/lib/xorg-server/Xorg (remove_fs_handlers+0x463) [0x43a7f3] [ 6497.071] (EE) 11: /usr/lib/libc.so.6 (__libc_start_main+0xf1) [0x7f2d13c54291] [ 6497.072] (EE) 12: /usr/lib/xorg-server/Xorg (_start+0x29) [0x4246e9] [ 6497.073] (EE) 13: ?
