I had to use the step 3 to be able to report the bug. The .crash file was uploaded to bug 1841428.
I noticed there is a backtrace in /var/log/Xorg.0.log.old which seems it was not uploaded. I'm not sure it is relevant, but here is the backtrace: [ 161.631] (EE) [ 161.632] (EE) Backtrace: [ 161.690] (EE) 0: /usr/lib/xorg/Xorg (OsLookupColor+0x139) [0x55e3d383e829] [ 161.692] (EE) 1: /lib/x86_64-linux-gnu/libpthread.so.0 (funlockfile+0x50) [0x7f45de62a8df] [ 161.693] (EE) 2: /usr/lib/xorg/Xorg (XkbCompileKeymapFromString+0x229d) [0x55e3d37dd00d] [ 161.694] (EE) 3: /usr/lib/xorg/Xorg (XkbCompileKeymapFromString+0x982f) [0x55e3d37eba1f] [ 161.695] (EE) 4: /usr/lib/xorg/Xorg (SendErrorToClient+0x368) [0x55e3d36e1548] [ 161.695] (EE) 5: /usr/lib/xorg/Xorg (InitFonts+0x3c8) [0x55e3d36e5528] [ 161.698] (EE) 6: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xe7) [0x7f45de248b97] [ 161.698] (EE) 7: /usr/lib/xorg/Xorg (_start+0x2a) [0x55e3d36cf18a] [ 161.699] (EE) [ 161.699] (EE) Segmentation fault at address 0x68 [ 161.699] (EE) Fatal server error: [ 161.699] (EE) Caught signal 11 (Segmentation fault).
