I'm also having this problem in a Compaq Presario F572US with Ubuntu 7.04 (Feisty). I removed the usplash package, the splash kernel boot option and added the vga=normal boot option and now I can swith to virtual console (Ctrl-Alt-F1) and back to X (Alt-F7) only if I am using the metacity (normal) window manager but if I enable compiz (composite manager) the problem comes back (blank screen with mouse pointer and must reset the machine).
Here is the hardware info: $ uname -a Linux f572us 2.6.20-16-generic #2 SMP Thu Jun 7 20:19:32 UTC 2007 i686 GNU/Linux $lspci ... 00:05.0 VGA compatible controller: nVidia Corporation C51 PCI Express Bridge (rev a2) ... I can't make suspend work with any window manager :'( -- [upstream] nvidia-glx doesn't restore state on NV35/NV36 cards.
