And how can I see why XWayland crashed? I updated my BIOS and thunderbolt controller firmware to the latest, I'm not sure if it made any difference. I tried disabling my display manager, booting into a console, and disconnecting and reconnecting the screen repeatedly. In that case, everything works fine. Unfortunately the coredump for the second gnome-shell crash never seems to complete. When it crashes after reconnecting the displayport adapter, often the caps lock light flashes on and off repeatedly for a few seconds, then the power light turns off (but the screen statys on). The image of the display manager flashed back on the screen, and then turned black. Next I saw the post screen (power light still off) for a few seconds, then the computer turned off. My microcode should be up to date - my bootloader is configured as follows: linux /vmlinuz-linux initrd /intel-ucode.img initrd /initramfs-linux.img and I have intel-ucode 20170707-1 which is the latest for Arch.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
