Thanks for your response. With a freshly installed Intrepid (and all upgrades) there has indeed been some development.
X11 still fails, but independently from whether the KVM switch is attached or not. Also, the output from xrandr and get-edid is identical, no matter how the monitor is connected. I'm attaching both Xorg logs (xorg.conf and xorg.conf.failsafe have been deleted; monitor is directly attached) and the output of both xrandr and get-edid (monitor directly attached). ** Attachment added: "edid" http://launchpadlibrarian.net/20035699/edid -- [radeon] xorg gives black screen with external monitor connected through KVM-switch https://bugs.launchpad.net/bugs/257941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
