But now that I see them I remember that they are for virtual consoles. I don't recall that they would affect the system-config-display actions. Regardless, you can pick one at boot time if "vga=ask" (without the quotes) and you'll see different character sizes. If you code "vga=xxx", where the "xxx" is one of those codes, they must be converted to decimal first. One of those links I posted later has a link to how to do that. But, as I mentioned, I now don't think this will affect the X setup. > > So, no graphic mode as I could find by googling > http://tldp.org/HOWTO/Framebuffer-HOWTO-5.html This link only has effect if you're using framebuffer. That's (IIRC) optional - I have it on my 4.x system, but I set it up a long time ago and would have to research to recall the details. It gave a nice speed improvement. Anyway, it's not mandatory. If you want to use it, more setup steps are needed. I would skip it now and continue what you're doing - get a basic acceptable setup running. > > If I use, as an example, vga=0x307, when I startx, I can see saying 4 desktops As I mention above, I think the hexadecimal needs to be converted to decimal. It's been a _long_ time, but I _think_ 0x307 = 775 decimal. But I don't remember if that value is big-endian or little-endian. Big, I think. > on the width of the screen and height of these desktop are only 1/10 height > on the screen, at the top of it > So, 9/10 of the screen is black. > > Regards, > Alain I saw that another posted some parameters to try with system-config-display. I'm going to peek at that and see what else I might offer. I might save my configs and play with system-config-display a bit and see if any clues pop up. -- Bill
