Hi Andrei, > GRUB_GFXPAYLOAD_LINUX=1440x900 > I know this variable. It is from grub2, I know. Besides I am still using grub- legacy, my problem is not to find the correct vga= for my resolution. I know this one. No, I could not find an answer, if the number from the "vga=" can be computed out of the wanted resolution. So, for example, 800x600x32 = 789h(ex) or whatever. > Kind regards, > Andrei Maybe my English is too bad, so my question is misunderstood. Best Hans
