Hi, all.

Once, again, I bow to the minds who congregate here, in hopes that someone can help with an odd problem with X on a laptop...

I have a Toshiba Satellite 4000CDT which I used to run RH8 & 9 on, as well as FreeBSD 4.7... and I never had a problem running X/KDE with either of those distros.

The video chipset is a CT65555, as auto-detected by Knoppix when running from CD. When booting from the 3.3 (2003-09-24) disc, the resolution is improperly detected as 1024x768x16: the actual resolution of the LCD is 800x600 (though the external VGA can probably handle higher). The system boots fine but only shows me two-thirds of the screen. Same with an HD install (which I had to perform almost blindly).

When I start from the CD, if I use the "fb800x600" cheatcode, the system works perfectly, and utilizes the correct screensize in X/KDE.

On the HD install, I've changed the /etc/lilo.conf file to have the line "vga=791" read "vga=789", and that gets the console working perfectly. But, when trying to start X, it gives a few blinks between console and black screen, and errors out. Trying to "startx" gives me:
Code:
(EE) FBDEV(0): FBIOPUT_VSCREENINFO: Invalid argument
(EE) FBDEV(0): Mode init failed
I've added an append in lilo.conf: "fb800x600", but get the same error.

I've mounted /dev/hda1 (boot/root partition) and copied both of the XF86Config files (-4 as well) from the running boot of the CD to the HD mount, so they are the same, and I still cannot start X from the HD.

Any ideas on what I may be doing differently on the HD? I've just installed this about three days ago, and haven't even put the machine on the network, so no packages have been changed/added/updated yet.

Thanks for any help!
Dan
