- Hi all,
-
- We have X11 Rel 4 PL14 running on Sun SPARCstations 1, 1+, and 2 running
- SunOS 4.1 and 4.1.2. We noticed a strange problem lately that we
- have not been able to isolate yet. After invoking xinit and a
- couple xterm's, we receive a message "Can't open display" after
- a few minutes. The error occurs when we try to invoke another X
- client. This occurs even if the workstation is idle after the xterm's
- are invoked. Nothing else is running on the system other than the
- normal SunOS processes. I think the message is coming from the server.
-
- I have seen this message before only when trying to make the condition
- occur (i.e., invoking many X clients to determine the display limit).
-
- Can anyone provide some insight into this problem?
-
- My next step is to debug the server which could be time consuming.
-
- ADDITIONAL INFORMATION:
- xinit sets the DISPLAY environment variable to unix:0.0. Even if I
- invoke xinit -display hostname:0. If I changed DISPLAY to 0:0 or
- hostname:0 in the xterm window, then I can invoke X clients from that
- xterm. STRANGE. The following are the DISPLAY values and the result
- from executing a X client:
-
- DISPLAY=unix:0 Can't open Display
- DISPLAY=unix:0.0 Can't open Display
- DISPLAY=:0 Can't open Display
- DISPLAY=:0.0 Can't open Display
- DISPLAY= Can't open Display
- DISPLAY=hostname:0 Can't open Display
- DISPLAY=0:0 Can't open Display
- DISPLAY=0:0.0 Can't open Display
-
- Side Note:
- 1. I didn't realize DISPLAY 0:0 is valid for X11R4.
-
- 2. Why is DISPLAY = unix:0.0 even after xinit -display hostname:0?
-
- 3. Why does 0:0 or hostname:0 work where unix:0.0 does not?
-
- Thank you,
- Richard Jackson
