Reece, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xorg REPLACE-WITH-BUG-NUMBER Thank you for your understanding. Helpful bug reporting tips: https://wiki.ubuntu.com/ReportingBugs ** Tags added: bios-outdated-a15 ** Description changed: + WORKAROUND: Connecting via miniDP-to-VGA, then to the projector, works + fine for me. + Synopsis: I get "No Signal" and an otherwise blank screen when connecting my Dell XPS 14" Ultrabook running 12.10 to Optoma HD20 projectors (we have two). The projector is recognized as connected. This laptop correctly displays on at least 5 other models of external monitors and projectors over HDMI without issue. Several Macs are known to work fine with these projectors. - Hardware Details: The laptop is a Dell XPS Ultrabook (L421X) running 12.10. This laptop has Intel 4000 and NVIDIA 630M graphics, and lsmod shows nouveau and i915 drivers loaded. This model has both HDMI and mini DisplayPort; results are identical for HDMI and the mini DP port (with miniDP-HDMI adapter). The projector is the Optoma HD20. This projector has two HDMI inputs and native 1920x1600 projection. We have two of them, and all behaviors described here are identical for both of them. snafu$ lsb_release -rd Description: Ubuntu 12.10 Release: 12.10 snafu$ apt-cache policy xorg xorg: - Installed: 1:7.7+1ubuntu4 - Candidate: 1:7.7+1ubuntu4 - Version table: - *** 1:7.7+1ubuntu4 0 - 500 http://us.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages - 100 /var/lib/dpkg/status - + Installed: 1:7.7+1ubuntu4 + Candidate: 1:7.7+1ubuntu4 + Version table: + *** 1:7.7+1ubuntu4 0 + 500 http://us.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages + 100 /var/lib/dpkg/status What I've tried: When I plug the projector into my laptop, the projector is recognized quickly as OTM 72" in Settings > Displays, but the projector declares "No Signal" and has blank display. (Is OTM 72" right?) Xorg.0.log shows frame buffer allocations that seem sensible based on laptop and selected projector resolutions. Clicking "Apply" leads to the 30s timeout dialog in which the laptop display is fine (i.e., not garbled) but the projector says "no signal". Both projectors work fine with Macs. I have tried multiple cable and cable lengths. I have tried multiple resolutions, with and without mirroring. http://harts.net/reece/tmp/optoma-hd20.edid-decode contains the edid info generated by edid-decode /sys/devices/pci0000\:00/0000\:00\:02.0/drm/card0/card0-HDMI-A-1/edid . 12.04.1 LTS behaves similarly. Rebooting with the projector connected has the same effect.
