I'm using the Trendnet TK-407 4-port USB KVM with Ubuntu 10.04 Desktop and having the same problem. Booting with screen connected directly works fine, but booting via KVM results in a blank screen. Same occurs with Ubuntu 10.04 server edition running in frame-buffer mode, i.e. screen blanks as soon as it switches to frame buffer.
To use the KVM I boot the PC's with the monitor plugged in directly, then after booting I can connect the monitor via the KVM. From here on I can switch between PC's without issues using KVM. I've attached the following files from the desktop: - Xorg.0.log (successful boot with monitor connected directly) - Xorg.0.log.old (unsuccessful boot with monitor connected via KVM) I've attached the following files from the server (with frame buffer): - syslog.2 (various successful and unsuccessful boots as per above) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/213895 Title: Ubuntu failes to work with KVM switch -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
