uvesafb mode_option=1366x768-24 mtrr=3 scroll=ywrapecho FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splashaby mi konzole a usplash běželo v rozlišení 1366x768 ale nestalo se tak dělal jsem to už několikrát a vždycky to fungovalo, ale tentokrát je rozlišení ještě menší než bylo původně (640x480) nemáte někdo zkušenosti?
