** Summary changed: - [hardy] Compositing + Xv causes SIGSEGV in memcpy() + [hardy] Xv causes SIGSEGV in memcpy()
** Description changed: - Binary package hint: xserver-xorg-video-intel + Changed the Description for the ubuntu stable release team. - Description: Ubuntu hardy (development branch) - Release: 8.04 - Arch: amd64 - Graphics card: i945 - xserver-xorg-video-intel: - Installed: 2:2.2.1-1ubuntu9~local1 - (a local build of ubuntu9 version, but the same problem appeared in earlier versions as well) - - I'm running a KDE environment with the KDE3 compositing manager to get some nice transparent terminals. - Sometimes when I try to play a video with Xv the server crashes in the driver. - The crash causes the text-mode ttys to become unusable but a new X server is started by KDM. + 1. This bug is very critical, It causes the xserver to crash if you use XV (X video extension). In the worst case you lose data. Every open Application gets interrupted. + 2. This bug has been fixed thought a new driver version in Intrepid. To fix this problem in hardy I have applied an commit from upstream that fixes this problem ( http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=commitdiff;h=1c0e4958564588162bc22a980567436dfc9d1e56 ). I have attached a debdiff that I have created against the latest proposed xserver-xorg-video-intel_2.2.1-1ubuntu13.5 package. So far I could not find any bugs/problems that may have been introduced through this patch. + 3. You can reproduce this problem by playing some videos with totem (XV as backend). If you play a HD-Trailer the xserver crashes much earlier. If composite (compiz) is activated doesn't show any difference. + 4. As I mentioned earlier I could not find any new bugs. Two other people have tested the debdiff with success. I don't know if the Graphics Media Accelerator X3100 is also affected. I know that the chips from 915 to 945 are affected. ** Tags removed: needs-bisection -- [hardy] Xv causes SIGSEGV in memcpy() https://bugs.launchpad.net/bugs/212799 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
