I too think that you are using the fb, whether you realize it or not. The logo is mentioned in the fb howto, and the first time I saw it (aside from the Debian installer, which had messed up colors) was when I started using the fb. For me, if I do anything that uses the whole screen the logo goes away. For example : start X, switch VT, run a curses app (ie less, vim or mutt). | Where are the documented steps for getting rid of the logo?

This is not a legal value (to the best of my knowledge). (Nice guess though ;-)). See /usr/share/doc/kernel-doc-2.4.8/Documentation/fb/vesafb.txt.gz for the various modes that are legal for the VESA framebuffer. Presumably they work for the matroxfb too, but I've only used the vesafb. If you set 'vga=ask' then you get a list of the VGA (not fb) modes that are allowed for your video card. I just found /usr/share/doc/kernel-doc-2.4.8/Documentation/svga.txt.gz which includes the following : --------------- The ASK_VGA mode causes the kernel to offer a video mode menu upon bootup. It displays a "Press <RETURN> to see video modes available, <SPACE> to continue or wait 30 secs" message. If you press <RETURN>, you enter the menu, if you press <SPACE> or wait 30 seconds, the kernel will boot up in the standard 80x25 mode. The menu looks like: Video adapter: <name-of-detected-video-adapter> Mode: COLSxROWS: 0 0F00 80x25 1 0F01 80x50 2 0F02 80x43 3 0F03 80x26 .... Enter mode number or `scan': <flashing-cursor-here> --------------- There is much more interesting information. The summary is that for standard VGA text console you want "vga=0x0F00". The fb is really cool though -- you get a better console since any resolution and font can be used. Also configuring X is as trivial as telling it to use the fb driver. No modelines, etc, to fuss with. The downside is that most cards are not accelerated (the Matrox and _some_ ATIs are supposed to be). | Does anyone know where I can find the lilo documentation that talks about | disabling fb?

Done, though using the Mail-Followup-To: header helps with this :-). -D
