These have occurred with both the Catalyst and radeon drivers, and also after booting with the x11failsafe option. They seem to be triggered by running KDE X clients on a remote (OpenSuSE 11.2) server connected by ssh with X tunnelling. For example, I can trigger it fairly reliably (not 100% but close) by running korganizer and selecting the File/Import dialogue...X11 crashes at the point it should display the file-picker window. My graphics card is an ATI RADEON HD 4650. There are two 1050x1680 monitors attached, though I have switched one of them off in the forlorn hope it might simplify matters. I have attached an Xorg log file showing a segmentation fault generated immediately after starting yast2 on a remote 11.2 system. The local machine was booted with x11failsafe. Reproducible: Sometimes Steps to Reproduce: 1. Connect to remote 11.2 system using 'ssh -X' 2. Select File/Import menu and select Import Calendar Actual Results: X server crashes Expected Results: File picker window should appear -- 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.

https://bugzilla.novell.com/show_bug.cgi?id=687171 https://bugzilla.novell.com/show_bug.cgi?id=687171#c3 --- Comment #3 from Bob Vickers 2011-04-18 08:55:12 UTC --- I would like to add another comment about the reproducability of this problem. I said in my initial report that it was close to 100% reproducable, but I now think it is slightly more complex. There seems to be some unknown factor which controls whether it is reproducable. On a good day I switch my computer on in the morning, login, and can use the problematic applications (e.g. korganizer) as often as I like without crashes. On a bad day I switch the computer on but have to walk on eggshells: X server crashes are reliably triggered every time I perform the known triggers. This behaviour sent me on some false trails to start with; I thought I had found a safe configuration but it turned out not to be so. -- 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.

I was musing as to why nobody else seemed to be suffering from this really nasty problem, and wondering what it was about my setup that was so unusual. The answer is...a font server. If I remove the font server from the font path then the problem goes away. What's more, we have four different font server hosts with similar but not identical configurations, and we use DNS to ensure they get selected on a round-robin basis. Three of these font servers provoke the crash but one does not, and this explains why I had good days when the problem did not occur. -- 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.
