Weird corruption with Xephyr
I'm seeing this rather weird corruption with Xephyr. The system is running Debian Lenny with a custom 2.6.27.4 kernel. I am running Xephyr 1.5.3. I've captured an image of this here: <http://seiner.com/images/imga0018.jpg> This happens after some time - can be minutes, hours or days. The screen just flickers and then wraps right a lot and down very slightly. You can see it in the poor quality image above (sorry for the poor quality image. That was shot with a handheld video camera). This has happened on 2 of the 3 Xephyr servers so far. It doesn't appear to be video driver related; I've been running various versions of nvidia binary blob driver for a while now. I have updated Xephyr from 1.5.1, and the problem appears since then. A second machine, which has the same video hardware, and still runs 1.5.1, doesn't exhibit the problem. I've been through all the logs I can find, and there is nothing at all out of the ordinary in any of them. I've considered hardware failure, but the problem occurs on both video cards in the system, so it's unlikely that both would fail at the same time in the same way. Is there some way to get Xephyr to generate verbose logs to try and capture this? Any other suggestions? --Yan ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

Please run nvidia-bug-report.sh after reproducing the problem and send the resulting nvidia-bug-report.log file to linux-b...@nvidia.com. -- Aaron ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

I've downgraded to Xephyr 1.5.0 which doesn't appear to have the problem (yet). If it's stable, I'll switch back to 1.5.3 and 177.82 and see if I can reproduce it. It may be a while as I am about to go on vacation and be away from all this until after New Year. :-) The reason I suspect Xephyr is that it doesn't appear to happen on screens adjacent to the broken one. In other words, on a dual DVI, single GPU card, I'd expect both outputs to be corrupt. Not so. It happens independently on each head, regardless of whether they share the GPU or not. --Yan ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
