Further observation (because this is so mysterious, but this phenomenon seems plausible):
The splash screen appears on both monitors now; whereas it only appeared on LVDS1 when DP1 wasn't working. Might be related, but it's unclear still. Might it be that some registers of the gfx chips are not reliably initialized? Are there any plymouth logs I could look at or enable? -- [GM45] [upgrade] [regression] [lucid]: external monitor only usable via DVI, not via DP https://bugs.launchpad.net/bugs/557436 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
