Thanks for the suggestions Bryce. My main problem is solved for now, but some mysteries remain:
First, I disabled gdm to diagnose. I downgraded to the previous versions of xserver-xorg-core and xserver-common using "dpkg -i /var/cache/apt/archive/<package>.deb" but continued to get a black screen when starting X manually. Mystery #1: Finally I tried enabling gdm again and it worked! I switched back to the latest xserver-xorg-core and xserver-common and it still worked! Other than adding the additional xserver-xorg-video-intel-dbg package, I should be back to the same configuration as when the issue first occurred. Mystery #2: I still don't understand why I can't start the X server manually. It always works when using "/etc/init.d/gdm start". When I kill gdm and try to start X using "/usr/X11R6/bin/X :0" or "startx" nothing but a black screen appears. I even tried duplicating the way gdm runs X, but still had no luck: /usr/X11R6/bin/X :0 -br -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7 gdm is doing something to make X work that I can't reproduce. If I can ever figure out how to start X manually, it may help me resolve the issue with resuming from a suspend. I have attached various log files. The main difference between the Xorg.0.log files is that the one that broken one doesn't show this section: (II) intel(0): EDID vendor "GWY", prod id 2186 (II) intel(0): Using EDID range info for horizontal sync (II) intel(0): Using EDID range info for vertical refresh (II) intel(0): Printing DDC gathered Modelines: (II) intel(0): Modeline "1680x1050"x0.0 146.37 1680 1784 1960 2240 1050 1056 1086 1089 +hsync +vsync (65.3 kHz) The broken one also includes this error message: (EE) intel(0): First SDVOC output reported failure to sync but that only shows up after doing a VT switch. ** Attachment added: "lspci-vvnn.txt" http://launchpadlibrarian.net/24490757/lspci-vvnn.txt -- Xserver black screen on 3/28/09 update of Jaunty https://bugs.launchpad.net/bugs/350399 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
