[Trisquel-users] Bootup Hangs on 5.0

[wmb1204]

Hi: I just updated to 5.0, and now when I turn on the computer, the machine  
boots to a blank black screen, and hangs. There is no disk or other  
discernible
activity. This machine is a test machine with replaceable drives, and I don't  
have this problem with for example Debian Squeeze. The machine is a Dell  
GX260, 2.4 GHz/40GB/1GB/nVidia 6200.

Intriguingly, if I press the power button to shut off the machine, it then  
proceeds to complete the boot process normally. Is this a GRUB problem or ???

Thanks in advance for any help you can offer.
