Dear maintainers,

I am using grub-pc since 3 weeks, and discovered, that it does not switch
correct to graphic mode when using nvidia-glx. It appears that way, if I
switch to console by using i.e. ALT+F2, the console ios not seen, but a
little white bar is seen on top. 

The console (shell) is existent, as I can blindly enter commands (i.e.
login as root is working and commands like "/etc/init.d/kdm restart") are
working well.

First I thought, the entry in /etc/default/grub were false, so I tested with
several resolutions: 1440x900, 1024x768x32 and 1024x768x16, but had no
success. In old grub-legacy I used the addon vga=791, which worked very
well.

At the moment I reverted back tp grub-legacy, which is still working
perfectly.

Additionally I am using a netbook (EEEPC 1005HGO with an Intel I915 graphics
chip), where grub-pc is working well. 

I suppose, there is a problem with the combination of either the Nvidia
hardware + grub-pc or nvidia-glx + software. It would be nice, if someone
might want to have a look at this. For me using grub-legacy is ok, but I
think in the future grub-pc (grub2) will be used as standard.

My system is a notebook with amd64-cpu, 2 cores, Nvidia GF8400M GS, stock
kernel and the nvidia drivers are built by DKMS.

Thank you for reading this bugreport.


Best regards
