Hi, in the last couple of days I've tried all the options I could think off: - 3D enabled (running Compiz and GL screensavers) or disabled (switching to MESA software implementation) - DRI/GLX on/off - DDC/DPMS on/off - ACPI/HAL on/off - xorg.conf's NoPM - CheckDevices on/off
I might have missed some weird combinations of all the above, but I tested a lot... Nothing there prevented my system from hanging on lid close :-( Peter's tst3 hasn't been very helpful in pinpointing the issue, as I didn't get any messages in the Xorg.0.log file. Looking for a way to "lie" to X and fake an external monitor, Peter then pointed me to this patch by Raúl Sánchez Siles: https://bugs.freedesktop.org/attachment.cgi?id=11492&action=view which forces the driver to detect an external monitor with the (undocumented) option Option "ForceEnablePipeA" "true" Using this patched driver and option, I get a better behaviour: my system happily blanks the monitor on lid closing, but does not hang. Hitting the keyboard or moving the mouse unblanks the screen correctly. However, I have a new problem: now my system locks on lid *opening*. This time, disabling ACPI (sudo /etc/init.d/acpid stop) works around the problem (rmmod video, disabling only the acpid socket, or using NoPM in xorg.conf are not enough): opening the lid has no effect, the monitor is still blanked but the system doest not hang. Keyboard/mouse do not unblank the screen, either, but switching to a text console and back to X works. I've put a .deb package of the patched driver online if anyone is interested in giving it a try (for the sourced just look into the same directory): https://webafs08.cern.ch/fwyzard/xserver-xorg-video-intel/xserver-xorg- video-intel_2.1.1-0ubuntu10~pcjc2.tst4_i386.deb -- xserver-xorg-video-intel hangs the system when laptop lid is closed https://bugs.launchpad.net/bugs/138256 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
