I have the same problem (Refer to Ubuntu Question #156639. MYTHBUNTU 11.04 - boots to blank screen
Mythbuntu Questions Question #156239 Asked by Roy Gilby on on 2011-05-06 I recently upgraded a Mythbuntu 10.10 frontend to 11.04. On all reboots after installation, the system booted to a blank screen, but from disk activity light and successful LAN access to NFS shares, the system is alive. Hardware is a Gigabyte Motherboard GA-H55N-USB3. It uses the Intel H55 chipset with an Intel i5 processor, and on-board intell H55 video to HDMI. If I boot into recovery mode from GRUB, and select "failsafeX", followed by "reconfigure graphics" and "create new configuration from this hardware", and then "restart X", I am able to log in and use the system BUT, the problem recurs at each reboot. I have now done a clean install from the 11.04 Mythbuntu ISO on the same computer, and have exactly the same problems as I had when I did the upgrade to 11.04 from 10.10. I have attached a copy of "failsafeX-backup..."in case that would be helpful. ** Attachment added: "copy of failsafeX backup tar file" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/758794/+attachment/2119369/+files/failsafeX-backup-110506173427.tar -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/758794 Title: HDMI black screen on Intel Clarkdale -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
