[Bug 242735] [NEW] [nvidia] 2 sec delay on 1 of 2 X screens, no xinerama

[Launchpad Bug Tracker]

You have been subscribed to a public bug by TobiasDomhan (tdomhan):

my Ubuntu 8.04 (86_64 version) is set up to use dual monitors (19" LCD,
and a 40" Sony TV) using two separate X Screens (no xinerama).

There is a 2 second delay before any menu appears on the LCD screen
(Applications/Places/System) or even a File/Menu/View inside Firefox.
Maximising windows is also subject to approximately a 2 second delay. I
am not using compiz, the problem is not present when using nv or vesa
driver.

The menus on the TV X Screen have no such problem, only the Monitor.
I've tried physically changing the wires on the graphics cards,
renumbering the screens, location, etc. the main screen always has a lag
when drawing menus.

I had the nvidia 169.12 drivers, before going through the pain of
upgrading to 173.14.09

I found this thread on the problem:
http://www.nvnews.net/vbulletin/showthread.php?t=114239 so I know I am
not the only one. Also, i do not think it is a compiz issue.

If I disable the TV, then the problem dissapears.

Thanks for any help. I attach the xorg.conf file.
