Unhappy You passed an undefined mode number

You passed an undefined mode number

Press <RETURN> to see video modes available, <SPACE> to continue or wait
30 secs

sorry for bothering you all with this question again... Iīve already read many threads with this subject and have already done everything I read, but noghing seems to work here with my slackware 9.0 ._.

I tryed pico /etc/lilo.conf

and changed to vga=771, and then to vga=773, and then to vga=788, and then to vga=ask, and then to vga=normal.... but when I try "startx" my monitor gets strange... some green and blue lines appear...

note: with vga=normal the "You passed an ..." didnīt show up, but the startx continued all messed ._.

I donīt really know whatīs happening... red hat and mandrake didnīt give me this error of "undefined mode etc...", so it proves my computer can work well with linux

knoppix gave me this "undefined mode etc..." in the beggining of the boot too, but I chose zero and then everything went well... I checked knoppinxīs lilo.conf and found a vga=normal in there... but in my slack, it doesnīt seem to work

I have an Intel 810 onboard video card... and knoppix detect something like this about my monitor: 30-54 Khz and 50-120 Khz....

what should I do??? óō

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.

I answered this in Newbie.

We just close it, deletion is for very bad things.

Slackware is a lot more optimistic with its framebuffering modes then the other distros. This is funny, as its pessimistic about everything else (some people would call that conservative.)

The i810 doesn't handle framebuffering all that well, you have to play it a little paranoid. The one I had around I think I had in standard VGA mode, and unless you're a big fan of ttys, who cares really.

X-windows is a different story, Slackware is the only distro out there that doesn't configure it for you, that's your problem. So... you have an /etc/X11/XF86Config file that is barebones... and built on the tada... vesa framebuffering driver, instead of the i810 driver. Back to buggy framebuffering.

X -configure

Run the test it tells you, and then copy over the /etc/X11/XF86Config file with that test file in /root/

It would have been easiest to save the XF86Config file from a previous install, and recycle it. Knoppix has about the best auto-configurator around, so you may just want to boot that and copy it to the drive, boot to slack and then copy it into /etc/X11. Of course, that's cheating, but it works.
