Ubuntu Login Form is Left of Visablity on the Login Screen

[Lonnie Lee Best]

Last night I installed Ubuntu 12.04 64bit onto my cousin's HP quad-core computer and HP 1080P monitor (I will post more hardware details tonight).

The installation went fine, and everything worked from the live CD using the "Try Ubuntu" option.

However, after installation, the login-form (on the login screen) was completely left-of the left-most pixel in the monitor, and (therefore) not visable to the user.

LightDM seems to be displaying that purple-studded-login-screen so largely, that it won't fit on the monitor, and (to make matters worse) the login screen is anchored top-right, so the login text-box (float-left) is about 5 inches to the left of where the monitors left-most pixels begins!

To discover this, I turned on the screen-speaking feature (from the top-right panel), and then I click the screen with the mouse. It told me (speaking out-loud) what I *SHOULD BE* seeing. So, I typed in the password *without being able to actually see the form*. It was kind of funny; for each password-letter I typed it spoke "asterisk" (asterisk asterisk asterisk . . .)!!! Anyway, I got logged in, and as a temporary work-around, I made his user account login automatically:

System Settings > User Accounts > Automatic Login > ON

I've experienced resolution problems with login-screens in the past, but previous version's login-screens were anchored top-left (not top-right), and the form was intended to be "center" (not float-left), so such issues were less severe because the form would have been just "off-center" (instead of not-visible).

Thank you for your bug report, was the screen resolution fine for your session after login? Does the issue happen if you use the nouveau opensource driver?

Sebastien,

After login, the resolution is fine; it is only *during* the login screen that the login *form* is NOT visible.

During installation, I did "check" the box that allows Ubuntu to use 3rd party packages. This problem occurred on the very first login AND all additional logins thereafter. I do vaguely recall changing the video driver from one (recommended) driver to another one "that was newer but not recommended", but it was (however) "listed", when going to System Settings > Additional Drivers.

As for "nouveau", I do not recall ever trying that driver (by name). Again, this issue persists on "my cousin's" computer, and I'm only able to report back as frequently as I visit him. Last night, I submitted the apport-collect from his computer.

Remember, I set his user account to login automatically (so he can expirence Ubuntu without having do a *blind* login each time), but after updating his machine last night with 120 updates (and then rebooting), I was able to see that the problem still persisted by "logging out"; that took me to the login screen where the login form still remains left of being visible.

Each time I visit him, I'll revist this thread also, so that I may provide any additional requested information.

nouveau? Will this automatically be installed by disabled the 3rd party drivers?
