Unfortunately, I never received any respo= nse, and after some months I kinda lost hope in upstream doing anything on this matter. Thanks for pointing me to Jon Turnery's MR, which I was not aware of. Upst= ream doesn't seem to have made any progress since then (almost 1 year and a half ago). Glancing at the MR, I have doubts about their approach, in particular the fact that this should be fixed in the server. I think it is likely it should fixed in xtrans instead. After all, this is where sockets are creat= ed or unlinked, which should not happen without a locking mechanism. Moreover= , as pointed out in the mail, the current lock file mechanism in the X server is logically incorrect and could be defeated in arguably rare or provoked situations. I may try to give it a new shot soon (next week perhaps), but not making ha= rd promises. Thanks and regards. --=20 You are receiving this mail because: You are the assignee for the bug.=
