[Bug 375551] New: acroread locks up X when it starts
https://bugzilla.novell.com/show_bug.cgi?id=375551 Summary: acroread locks up X when it starts Product: openSUSE 10.3 Version: Final Platform: 32bit OS/Version: openSUSE 10.3 Status: NEW Severity: Normal Priority: P5 - None Component: Commercial AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: sitsofe@yahoo.com QAContact: qa@suse.de Found By: --- Description of the problem: Upon starting acroread for the first time the desktop will become unresponsive to clicks for about 25 seconds on a P4. Steps to reproduce: Assuming no instances of acroread are running (e.g. no acroread browser plugins or processes) 1. As root issue the following: echo 1 > /proc/sys/vm/drop_caches As a regular user run the following 2. Start a terminal and run top -d 0.5 3. Press alt-f2 and run acroread . Expected results: Updates to the desktop to continue happening. To be able to click on other programs and use the desktop as acroread is loading. Actual results: Updates (e.g. top inside the konsole) stop happening. Desktop is unresponsive, mouse pointer still moves but clicking on other windows does nothing until acroread has finished loading. How reproducible is the problem? Providing the caches are cleared every time it is reproducible every time. Additional information: Using ionice -c7 acroread and nice -19 acroread makes no difference. Regular Xorg (not XGL) is being used. Reproduced on a Pentium 4 CPU 3.06GHz + Radeon 9600 using the open source driver and a dual core Pentium D CPU 2.80GHz + NVIDIA 7600 using the binary only driver. Switching to a virtual console and using command line apps works. Might be a xorg bug.

If this happens the user has to log in at a virtual terminal/ssh and then kill off acroread with -9 before X will respond to mouse clicks again. -- 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.

You should avoid grabbing the X server as much as possible.

Yes, I think acroread has no good reason to grab the X server and should stop doing this. acroread is a normal application, not a screen saver. -- 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.
