i915 is a module with kms enabled, the blur seems to show up on the text console the moment that the module gets loaded during boot. Before that, the console is in VGA text mode, which is always slightly blurred because the screen has a different native resolution.
Arg why would the BIOS set the panel fitting bit at all in this config? Any attached outputs (VGA, HDMI) will have their own scalers...
I didn't think the BIOS was setting it. Text mode appears to be blurred differently, but that's hard to tell...
Obviously we need to clear it somewhere, but we should be able to avoid clearing it on every mode set. We should probably shut down all panel related bits in intel_lvds.c if we fail to detect an LVDS output; that should save a little power and avoid problems like this.
Maybe the below patch which does that will help?
No luck here either.
I don't think the code path you patch here actually gets used, since intel_lvds_init gets called by intel_setup_outputs only for mobile devices.
