I also agree that the default resolution at the login screen is ugly. Low resolution mirroring is bad. Windows 7 is using only the external screen at its highest resolution at the login screen.

[Bug 874241] Re: Wrong resolutions in lightdm login screen when using external monitor connected to laptop
Yeah I happened to notice the exact same thing today. I have REALLY unstable sessions when having dual monitors plugged in. Either I randomly loose dual monitor setup (https://bugs.launchpad.net/bugs/921540) as well as sometimes having my desktop crash when connecting the screen in a live desktop session (https://bugs.launchpad.net/bugs/926637). Neither of those bugs getting any attention btw. Anyway so to avoid at least one of those bugs, and the frequent loss of data, I logged out yesterday and connected the monitor. To my surprise I could see that cool new feature when only one screen has the login screen and the other has the ubuntu logo. Moving my mouse between the screens switches the login screen to the focused screen. If this works then what is not working during boot?

[Bug 874241] Re: Wrong resolutions in lightdm login screen when using external monitor connected to laptop
Although an xrandr script could work, if the dual monitor configuration is intended to be permanent then a better solution is to supply a valid xorg.conf. I just had to do this when switching from the nvidia proprietary drivers to nouveau (just experimenting). Jockey blows away the xorg.conf (for good reason) but no suitable dual monitor configured xorg.conf is supplied. This makes the lightdm + greeter revert to default behavior which is to match lowest resolutions on both monitors.

[Bug 874241] Re: Wrong resolutions in lightdm login screen when using external monitor connected to laptop
The way the login display manager should look is now defined in the Design team multimonitor specification. Rather than mirroring (which causes this bug) lightdm needs to set the screens to extended, with the primary screen showing the login and the secondary showing a logo. It probably makes sense to leave the X to the upstream default of mirroring, and tie in with the settings daemon stuff. We can evaluate if a more direct link to libxrandr-utils might make sense later. ** Package changed: xserver-xorg-video-intel (Ubuntu) = unity-greeter (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874241 Title: Wrong resolutions in lightdm login screen when using external monitor connected to laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-greeter/+bug/874241/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 874241] Re: Wrong resolutions in lightdm login screen when using external monitor connected to laptop
So, what's going on here is that the display manager is setting the displays to mirrored. In X, 'mirror' means 'find a common resolution supported by both monitors'. Unfortunately, in cases where the aspect ratio of the two displays differ, there will be zero XxY resolutions they have in common, and so X has to select the default VESA mode of 1024x768 (or one of the smaller required modes like 640x480 or worse). While this is the expected behavior, you're right that it looks really bad, and since it's the first thing people see it gives a poor impression. Certainly doesn't fill one with confidence that multihead in unity is going to work well. Unfortunately, most options to solve this have fairly nasty corner cases that can leave users with an unusable system, or at least extremely confused. So, I agree this is a bad problem, just not sure how it should be fixed. Fwiw, I experimented with scaling the external monitor while it is at 1024x768: xrandr --output HDMI2 --scale 1.33x1 and that looked better. However the text looked bad (mis-hinted?) and it did nothing for the black bars on the laptop display, so this isn't even a viable workaround. ** Changed in: xserver-xorg-video-intel (Ubuntu) Importance: Undecided = High ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874241 Title: Wrong resolutions in lightdm login screen when using external monitor connected to laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/874241/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
