You have passed an undefined mode number.

OK.. I know this topic has been brought up several times in this forum but despite my efforts i cant seem to get my framebuffering to stay working.

I am using a Gateway Solo PII 333mhz, 128mb, Trident video, Slack9, default 2.4.20 kernel and the 2.4.21 kernel.

Problem seems to go like this:

-install slack9
-chose for lilo to boot 1024x768x64k
-install lilo to MBR
-everything boots/runs pefect including framebuffering
-after about 1 or 2 reboots, it gives me the You have passed an undefined mode number error and remains fucked up no matter what i do

I have tried this several times, reformatting each time as i go. I also have tried the newer kernel and that gives me the same crap

I have had a little luck however, everynow and then it DOES work (for some odd fucking reason) but it will promplty go back to not working once i reboot. X doesnt work either in the text mode.

I have tried using hex, i have tried vga=scan , all , normal , etc. nothing works. However the first time i tried putting the hex it, it did work. But again, only for one boot. I have all the stuff enabled in Console Drivers.

my lilo.conf currently looks like this: (and i get the error)

image = /boot/bzImage
root = /dev/hda1
label = Linux

the only thing that gives me something other than the error message when i boot, is using a 800x600 resolution, in which case it makes my screen flash blue lines. Not exactly working either ...

Anywho, any help would be much appriciated.

Just a little note, now i cannot the other kernel to boot, it gives me the flashing blue lines.

First of all, try to refrain from using so much slang. This is an open forum and there's no need to use such descriptive words. And yes, some do get offended, if you only knew how many emails I get of people complaining about language used in members threads.

Second about the problem. I never use 64k framebuffering when booting to a console. It either never works or just causes problems. Have you tried a lower resolution like 1024x768x256?

Have you tried changing it to vga = normal in your lilo.conf file and running lilo to make the changes? Reformatting and or changing kernels most likely isn't going to change the errors your getting.

And I'm confused when you say: X doesn't work either in text mode?

vga=normal should work, now keep in mind you'd lose the nice little penguin up in the top left but I'm sure you';ll manage

sorry about the language...i've tried vga=normal and it works, but its not the desired resolution. I'm going to try the 256 one right now so hopefully that will do the trick. And as far as X goes, it gives me the "No screens found error" when i get the "you have passed a bla bla bla" in the begining. Again sorry about the language.

**i take that back, normal doesnt work either now (this is so messed up..). Things seem to work once then quit

i'm having the same problem now. I installed slack on an ooold machine, just for practice since i'm newish to linux. in windows, the monitor would only allow 640x480, but I could get the 1024x768x256 framebuffer to show up nicely. Now, trying to get slackware up on my own computer, none of the framebuffer modes work. I tried every one, and reinstalled lilo each time, but received the "undefined mode" crud. and running "startx" gives a garbage screen in the "normal" or "safe" mode (text mode maybe...the one w.o tux). is this a videocard/monitor problem or is it simply something else that needs to be setup?

i think i mave have found something, in the bios i changed it from LCD&CRT output to just LCD (dunno why that would affect anything but it seems to have) and now it appears to be doing the framebuffering like a good little computer...i hope it lasts :\
