However, when I try to switch the VGA=788 line in grub's menu.lst to VGA=791, I get an invalid video mode message. Does anyone using Matrox know why this is, and if there's a simple way to get a little higher resolution than 800x600 on the consoles?
Invalid Video Mode applies to the monitor not the video card. Since you changed the video card the monitor definition needs to be updated too. Try sax2 and if that doesn't work you may need to use sax2 -l for low resolution, define the monitor then define the video card and resolutions.
The actual error message was: "You passed an undefined mode number." I also have a 9.0 system with a G400, and it behaves the same way. :-( However, I get no such error using ET6000 video on Mandrake 10.2 on the same Sony 200GS display, or using ET6000 video on RedHat 6.2 on the same 200GS display, or using ET6100 video on SuSE 9.2 on a 2nd 200GS display, which also does vga=794 just fine. And, all that work AFAIK have never had any special config program run to make 791 or 794 work. In fact, it seems the GUI Linux installers all seem to use either mode 791, or something higher, maybe 794, or some still different framebuffer mode? vga=778 works with the G400 during the first phase of boot, 143x43 I think, but it switches to only 21 lines shortly before "creating /var/log/boot.log" displays. It seems to me the monitors themselves are fine. I read http://www.tldp.org/HOWTO/Framebuffer-HOWTO-5.html#ss5.4 but it isn't clear that it applies to a G400 or that it isn't an optional way to configure for Matrox. I'm not trying to change any X settings here. Are you saying I have to configure *monitor* (display) settings somewhere in Linux config files for use on tty[1-6], and that's what sax2 -l should do? All it seems to affect here is X. -- "In everything, do to others what you would have them do to you." Matthew 7:12 NIV Team OS/2 ** Reg.
