Re: [TEKNIK] text mode med grafikdriver uden x i Grub2

Tak for tippet. Jeg kiggede på siden, og prøvede en række forskellige video 
modes. Og intet af det virkede.

Den grundlæggende skabelon for mine forsøg ser sådan ud (det er linien der 
starter med 'linux' der er interessant):

menuentry 'Command line' --class ubuntu --class gnu-linux --class gnu --class 
os {
        recordfail
        insmod ext2
        set root='(hd0,2)'
        search --no-floppy --fs-uuid 
             --set 823640f9-cbb9-43d6-a516-c72aed271875
        linux   /boot/vmlinuz-2.6.32-30-generic-pae 
             root=UUID=823640f9-cbb9-43d6-a516-c72aed271875 3 ro   
             quiet splash text vga=784
        initrd  /boot/initrd.img-2.6.32-30-generic-pae
}

Når jeg prøvede med et grafik mode, så gik maskinen ned under opstart, hvis 
med lod 'text' blive stående, og uden 'text' så startede den X op.

Når jeg prøvede med et text mode (264-268) så startede den X, hvis jeg udelod 
'text', og hvis jeg lod 'text' stå, så ser det ike ud til at nVidia driveren 
bliver loaded. CUDA API'et kan i hvert tilfæld eikke genkende grafikkortet som 
et CUDA grafikkort (det er det, jeg har checket, og samme program kan genkende 
grafikkortet, når jeg kører det under X).

Hvordan løser jeg det problem? Mit problem er at jeg skal bruge CUDA 
funktionerne på mit grafikkort til nogle beregninger, men der er ikke RAM nok 
på kortet, til både at have X kørende /og/ et CUDA program, så jeg skal starte 
i text mode, men med nVidia driveren loaded, for at få adgang til CUDA 
funktionerne.
