As mentioned, the freeze doesn't happen every time. I noticed it happens quite often when I exit UrbanTerror ( quake game mod ) and try to turn back on compositing.
** Summary changed: - System freezes when reenabling compositing in kwin-kde4 + X freezes when reenabling compositing in kde-window-manager ** Tags added: freeze xorg ** Description changed: I run Kubuntu Hardy with KDE4. My system freezes when I press shift- alt-f12 twice. shift-alt-f12 is supposed to toggle compositing (desktop effects) in kwin, so hitting the key combo twice would first disable compositing ( this works fine) and then enable it again - but at this point it freezes. Let me explain 'freeze'... The mouse cursor still moves, although I don't get any hover effects on widgets. The keyboard appears dead. Hitting alt-ctrl-f1 to switch to a virtual terminal doesn't work, alt- ctrl-backspace to kill X doesn't work either, and hitting CapsLock doesn't toggle the CapsLock LED. The only thing I can do at this point is to hit alt-ctrl-sysrq-b to reboot. Toggling compositing works when going to System settings->Desktop and checking/unchecking "Enable desktop effects" and hitting Apply. I have a HP Compaq 6720s notebook with an Intel x3100 card. It uses the i915 driver. I will attach the lspci output. Please let me know if I can provide any other piece of info that may help. I am currently using kde4 packages from kubuntu-members-kde4 team's ppa archive, but I remember this also happened with stock kde4 packages. + + Using xorg-7.3+10ubuntu10, and xserver-xorg-video- + intel-2.2.1-1ubuntu13.5. -- X freezes when reenabling compositing in kde-window-manager https://bugs.launchpad.net/bugs/249251 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
