I get this same issue, on a Toshiba Portege R500 laptop with a BENQ T24IWA external monitor. Rebooting with the screen attached is the only way to get my desktop on the screen in a usable manner, and then it works perfectly. However, after doing this, I can never get my laptop screen back after a suspend, even if I switch display settings back to the laptop monitor before suspending.
I'd be happy to gather more debug info to help resolve the issue. -- Cannot switch Monitor configuration CRTC 58 https://bugs.launchpad.net/bugs/484186 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
