I have the same issue. My machine is not a laptop but uses mobile CPU. With Precise, VGA works but DVI and HDMI do not work.
I know the machine worked just fine with Lucid. So, I downgraded xorg to Lucid. It does not fix the problem. I brought back xorg to Precise. I also tried the tip of xorg from PPA and did not fix the issue. Then, I downgraded kernel to Lucid. That fixed the DVI output. Kernel that works is 2.6.32-33-generic. 3.2.0-xx-generic deos not work. When DVI is working, in "Display" control panel, the DVI is recognized as "Digital display" while VGA display's maker is recognized correctly. When DVI is not working, in "Display" control panel, the DVI and VGA's makers are both correctly recognized. According to /var/log/Xorg.0.log, DVI1 is correctly recognizing the monitor EDID, sets up the resultion, etc, but the signal is not coming out. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/689221 Title: No DVI output on Intel 82G33/G31 in Maverick Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: Binary package hint: xorg On an ACER ASPIRE L3600 after a clean install and after latest updates of Kubuntu / Ubuntu 10.10 (32/64bit, doesn' t matter) DVI output fails, VGA works fine though.
