This means that If I need to access console, it will probably be blanked. For some servers, console access is needed less than once per year, if ever. But IF the console need to be accessed, there's a strong reason to it (some kind of fault), and having to press anything to unblank may be invasive. I would prefer to fix the issue at the source, instead of sticking "consoleblank=0" in grub2.cfg on houndreds of boxes. BTW, kernel already contains "consoleblank=0" in arch/arc/boot/dts/nsimosci.dts and arch/arm/boot/dts/omap3-lilly-a83x.dtsi Is LCD damage for currently produced LCDs real issue, still? -- Tomasz Torcz To co nierealne -- tutaj jest normalne. xmpp: zdzichubg@chrome.pl Ziomale na życie mają tu patenty specjalne. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
