http://bugzilla.opensuse.org/show_bug.cgi?id=1174493 Bug ID: 1174493 Summary: x11vnc cannot connect to X server anymore Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: gfx-bugs@suse.de Reporter: P.Suetterlin@royac.iac.es QA Contact: gfx-bugs@suse.de Found By: --- Blocker: --- I just did an TW update 20200701->20200721 (on two machines) After this update, I cannot connect to a running X server on the updated machine anymore. I use x11vnc_ssh for this, i.e.: woodstock:~% x11vnc_ssh astro@astro1 (woodstock and astro1 are the two 0721 machines). I get an error right away Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 key25/07/2020 21:21:45 XOpenDisplay(":0") failed. 25/07/2020 21:21:45 Trying again with XAUTHLOCALHOSTNAME=localhost ...

So it seems something has changed on the server side. 0701 has x11vnc-0.9.16-2.1, 0721 has x11vnc-0.9.16-2.2, so it was only recompiled... -- You are receiving this mail because: You are on the CC list for the bug.
