You passed an undefined mode number???

Gotcha....

Anyway, I don't just want my students to work with KNOPPIX, I want them to have fun and enjoy their Linux experience. They should see that KNOPPIX is for work and fun.

Just spreading the word, man!

BTW, 20030905 fixed my sound problems!

Thanx Klaus,

I can confirm that there is still an issue with the Intel 82865 integrated video card on Dell computers.. This problem is still there with the latest Knoppix 3.4 2004-05-17 build. Works but only in 640x480 mode regardless of startup options gleaned from cheatcodes.txt.

I don't need the cheatcodes anymore. Its something in the Dell BIOS about max VRAM used. The default on mine was 1MB even though there's 8MB on board. So I just reset that in the BIOS and all is well!

Don't know if this is much help, but two things come to mind:
1. If you are using xmms to play your ogg files, you may need the xmms-arts plugin. The arts daemon interferes with xmms if it's running...and KDE will autostart artsd if it thinks it needs it.
2.I have always had to deal with the 'undefined video mode' error (originally I actually thought it was just a Linux quirk). It comes from Knoppix being set for vga=791 as a default. If you are HD installed (I know you are not but FYI anyway) you have to change vga=791 to vga=normal in lilo.conf. I don't know where it is set if running from CD, you have to use a cheatcode to get rid of it...or a persistent home/saved config setup.

Thank you AJG, you are quite correct. Once you change the VRAM from 1MB to 8MB all issues go away.

Well nearly all, now I get two 'tux' Penguins instead of one on bootup. I consider it a bonus

What a splendid resource this forum is.

And you should, since it most probably means your PIV is HyperThread capable and used as such by the knoppix SMP-enabled kernel.

CrashedAgain: You're right, sometimes, especially if I want knoppix-installer to work right, I still have to run

Code:

knoppix vga=normal screen=1024x768 vsync=60

JP: You're most welcome! Yes, this forum is a great resource and most everyone is friendly and very helpful. That's why I've been on here so long and written so many posts....

Put me down as being another happy user!

Had been frustrated for a few days as Knoppix was only running 640x480.

Increasing the video buffer to 8mb has fixed my problems thanks to the comments made in this forum.

Why Dell ships these with only 1mb specified in the BIOS is beyond me?
Anyone else got an idea why they use value by default?

Thanks.
Ian.

P.S. I'm using Dell SX260 with Intel 82845G or similar
