Screen stops updating when starting compositing manager?

Question

linux

Card: 01:00.0 VGA compatible controller: nVidia Corporation G72 [GeForce 7300 LE] (rev a1)
Ubuntu: 11.04 i386
Drivers: nvidia-current 270.41.06
Tried running compiz, mutter and xcompmgr. In the first two cases, the screen content stops being redrawn, although the system works, for example, you can drag windows (only this is not visible, it becomes visible after the window manager is killed). Switching to another console and back does nothing. In the third case, you can draw on the screen with shadows from windows (as in the good old days in a frozen Windows XP with window frames on the desktop).
Mutter doesn't write anything, compiz crashed into segfault several times when killing it with kill.
In general, it is the compiz that is needed because of its effects, namely the increase in the desktop, which is very useful when you cannot see from the sofa what is written on the TV, which is used as a second monitor.
Please do not offer Nouveau, 3D does not work normally with it, this time. Artifacts in the form of lines often appear, these are two.
The nvidia drivers of the previous version do not allow you to set a resolution other than 640x480 on the TV, besides, when using them, the splash screen turns into garbage during loading, which of course is not critical, but unpleasant.
I'm waiting for tips, otherwise it turns out inconveniently, the girl promises cuffs. :)
I set to show Ubuntu and ran into jambs with drivers.

Answer 1

Try running compiz with --indirect-rendering

Answer 2

Unity is a plugin for compiz. Therefore, if you see the Unity panel, then compiz is working.

Answer 3

Hmm, have you tried using GNOME or KDE on the same machine? Compiz with similar symptoms did not work for me just because of unity.
