https://bugzilla.novell.com/show_bug.cgi?id=484026 Summary: X11 applications do not start anymore; error message "No protocol specified" and "Can't open display: :0.0" Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: i686 OS/Version: openSUSE 11.1 Status: NEW Severity: Normal Priority: P5 - None Component: X.Org AssignedTo: bnc-team-xorg-bugs@forge.provo.novell.com ReportedBy: mail@Franosch.org QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.10 (like Gecko) SUSE When working under KDE3, after some time (hours, days) no X11 applications start anymore. When trying to start xterm in a (already open) konsole shell by xterm the following error is displayed: No protocol specified xterm Xt error: Can't open display: :0.0 When trying to start X11 applications via the "Run command" dialog (Alt-F2, xterm) the application will not open a window. This is bug because using the Alt-F2 dialog or the menu, it should always be possible to start new applications. I currently know no method to reproduce the bug. It seems to simply occur after having been logged in for a relatively long time (hours, days). It does not seem to be triggered by special programs or activities although I am not sure about this. You can "cure" the bug by logging out and logging in again. Or you can cure it by doing "su" in a konsole shell and then log out of this shell again. After this procedure "xterm" can be started again in the konsole shell where you did "su". But not only there. It is now again possible to start xterm in every konsole shell and also by the Alt-F2 dialog. If you just open a new konsole shell (without doing su before), then you will not be able to start xterm in the new shell. So just opening a new shell does not cure the bug. For an ordinary user, there is no obvious way to work around the bug, it just appears as a system hang or crash. Therefore, it should be fixed. How can I debug this further, when the bug occurs? Thank you very much. Reproducible: Sometimes Steps to Reproduce: It is hard to reproduce. It seems just to occur after some login time or by chance. The home directory is mounted by NFS. The server runs Suse Linux 10.2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
