That broke my framebuffer! If I boot like this: Command line: root=/dev/md2 video=nvidiafb:640x480-32@60 atkbd.softrepeat=1 I see this: nvidiafb: Device ID: 10de0392 nvidiafb: CRTC0 analog found nvidiafb: CRTC1 analog not found nvidiafb: EDID found from BUS1 i2c-adapter i2c-1: unable to read EDID block. i2c-adapter i2c-1: unable to read EDID block. i2c-adapter i2c-1: unable to read EDID block. nvidiafb: CRTC 0 appears to have a CRT attached nvidiafb: Using CRT on CRTC 0 nvidiafb: MTRR set to ON Console: switching to colour frame buffer device 64x26 nvidiafb: PCI nVidia NV39 framebuffer (64MB @ 0xC0000000) But the screen is unreably corrupted. I can describe the corruption as follows: The two penguins I normally see are about the correct size, but shown in dark grey lines on a black background. All characters are also composed of these dark grey lines - with black lines inbetween. The entire screen is very faintly visible, all is dark grey on black. The monitor does receive the correct signal (my Eizo's on-screen menu shows a 60 Hz signal coming in). In case anybody is wondering about the resolution - normally I boot 1600x1200, but that also doesn't work. Xorg works fine, so it must be something in the framebuffer, right? xorg's version: ii xserver-xorg-video-nv 1:2.0.2-1 X.Org X server -- NV display driver output of lspci: 01:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7600 GS] (rev a1) (prog-if 00 [VGA]) Subsystem: Micro-Star International Co., Ltd.
