@Brad Figg I'm unable to add report with 'apport-collect 1153627' - can't find workaround for "ERROR: connecting to Launchpad failed: [Errno 1] _ssl.c:504: error:14090086:SSL outines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed"
@Joseph Salisbury Tested using: linux-image-3.9.0-030900rc2-generic_3.9.0-030900rc2.201303102035_i386.deb linux-image-extra-3.9.0-030900rc2-generic_3.9.0-030900rc2.201303102035_i386.deb A bit different manifestation but same underlaying problem exist upstream: - Kernel is able to boot without hanging. However, looks like error is not triggered because resolution is automatically set at 1024x768 for all outputs. - Issuing: xrand --output VGA1 --auto --output DP2 --auto --output DP3 --auto 1. triggers the same continuous errors: ... [drm:intel_dp_set_signal_levels], Using signal levels 00000000 [drm:intel_dp_set_signal_levels], Using signal levels 02000000 [drm:intel_dp_set_signal_levels], Using signal levels 04000000 ... 2. at this point xserver stop responding, xrandr is unusable 3. but I can confirm from monitor OSD that VGA1 and DP2 are correctly set. Monitor OSD connected at DP3 state "No signal". ** Attachment added: "Xrandr report after succsessful boot" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1153627/+attachment/3570331/+files/xrandr.txt ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1153627 Title: Kernel hangs while booting if there is a monitor connected to DP2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1153627/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
