I am running Slitaz from liveCD on my Sony Vaio PCG-FX109K (Pentium 850 MHz and 512 RAM). But when the program loads I only get limited screen resolution rather than the 1400x1050 of which the screen is capable. How can I reset the resolution to 1400x1050 either at boot or when Slitaz is running? I have tried 'slitaz vga=1400x1050' at the boot prompt but without success.
