XSPLASH: Displays incorrectly on multi-monitor setups

[Nicholas Christian Langkjær Ipsen]

There are three fairly big problems with multi-screen Xsplash(Using nVidia TwinView with two monitors at 1920x1080)

1. The wallpaper is stretched across all sceens, even though the logo, throbber and login dialog only appear on the primary screen.

2. The throbber and logo look... weird. Try it using my setup yourself, you'll see. I'll take a picture if you find it impossible to reproduce.

3. I can see my desktop loading.

Please attach a picture - it would help.

Thanks,

Here's something better: A video.

"1. The wallpaper is stretched across all sceens, even though the logo, throbber and login dialog only appear on the primary screen."

This is not actually xsplash. That's the desktop background being drawn by gnome-settings-daemon.

The video was interesting. It seems like xsplash is not loading the background image for you. Can you open up a terminal and run:
   sudo -u gdm xsplash

And confirm that it does the same thing?

Also, please post the contents of /var/log/gdm/xsplash-user.log here after you've reproduced the issue (e.g., if you run xsplash from the terminal and the problem doesn't happen then don't post xsplash-user.log, logout/login first).

[Cody Russell (bratsche)]

Also, before doing that can you post the xsplash version you're using and make sure you're up-to-date?

[Nicholas Christian Langkjær Ipsen (ncli)]

I will do all of it as soon as I've finished doing a clean install to make
sure it's not just leftover stuff from the pre-release versions

After a clean isntall, this went away. I guess it was a remnant from somewhere in the Alpha period.

Actually, the grey box clip region still appears here exactly as in the linked video.

I wouldn't mark this as invalid just yet.

Running Xinerama off of dual ATI cards, so it appears to be something regarding implementation as opposed to video card related specifics.

[Robert Collins (lifeless)]

Troy, please supply the data that Cody was asking for then (the manual test results and the log and xsplash version info).

[Troy James Sobotka (troy-sobotka)]

How odd... Apparently I'm not subscribed to this bug. Sorry for the late response. Give me a few...

"It seems like xsplash is not loading the background image for you. Can you open up a terminal and run:

sudo -u gdm xsplash

And confirm that it does the same thing?"

Answer: Confirmed. A grey rectangle appears in the upper left of my leftof screen.

I have this exact same problem on my Ubuntu 32 bit, upgraded from Jaunty, never had Karmic alpha/beta installed. Nvidia card running in TwinView mode using the latest 190.42 driver manually installed. Nvidia card 9500GT. Problem is exactly like the YouTube video link. When I run "sudo -u gdm xsplash" it looks the same way as during boot up. xsplash 0.8.5 from Karmic updates repo is installed.

Here is the log after running "sudo -u gdm xsplash". My TwinView screens are setup as 1280x1024 (primary DFP) and 800x600 (NTSC TV) to the "right of" the DFP. Nvidia sees my screen in xorg as 2080x1024. I have some other metamodes setup but only used for fullscreen games, see below.

Hi,
I have this exact same problem on my Ubuntu 64 bit, upgraded from Jaunty yesterday (xsplash 0.8.5-0ubuntu1).

It's not only multi-screen setups that are affected. I'm running a single screen (1440x900), with nVidia drivers version 185.18.36, and am getting the grey rectangle on boot and when running sudo -u gdm xsplash.

Logs follow:

[Peter Hurley (phurley)]

Here's a patch for this bug against the karmic/lucid source package xsplash-0.8.5-0ubuntu1.

The approach I took was to wipe the whole X screen (in TwinView, this is both monitors) with the background image, and then display the logo and throbber (that's what it's called...) on monitor 0 (the default monitor). The background image is isotropically scaled to match the largest dimension and centered in the other dimension.

Also, the original source allowed the source background image dimensions to vary and I preserved this behavior. This means if you are running dual 1920x1280 monitors in TwinView, you can supply a 3840x1280 jpg and the image won't be scaled. (Although since I didn't test this, there might be an off-by-one error in which case it will scale).

I tested this on a dual-monitor NVidia in TwinView, single monitor and separate X screens, running driver version 185.18.36 (stock karmic but rebuilt for custom kernel).

I'm closing the Ubuntu task, since there is already an xsplash task.
