Dell LS500 - Frame Buffer support causes purple text consoles

Upon gui Anaconda install, when X starts using frame buffer, all text
consules (e.g. tty2) are subsequently purple in colour. When swapping from
X to tty2 the X screen first changes to purple, and then the new console is
I tested using vga=787 on an installed system, and once X is started (in
800x600x64k) again the other consoles change to purple from the standard
"grey". I installed kernel-2.4.0-0.99.24 and XFree86-*-4.0.2-7 and the
problem still exists.
Steps to Reproduce:
1.Start gui anaconda installation
2.Change to tty2 (<ctrl><alt>2)
Actual Results: Frame buffer support on LS500 gives purple consoles.
Expected Results: Normal colour consoles.
It works correctly until X starts, right?
Yes, that's correct. The kernel loads, we get correct text for the kernel
messages, we probe for video, X then starts with the correct colour. The problem
is moving from the 800x600 X display back to a text console (<Ctrl><Alt><F2>).
Moving back to the X display (<Ctrl><Alt><F7>) restores the X display with the
correct colours again.
I'm attaching the ddcprobe and the XF86Config.test for you also.
I can test any patches you have.

Looks to be fixed in standard wolverine installation from CD. Could this have
been a 15bpp/16bpp issue?
No idea. Every new XFree package is resync'd with XFree86 stable branch
of CVS via patch #0 though, so it is possible a new fix got in that I didn't
see. I'm closing this since you say it is fixed now. Hope that is ok.
So you know... vga=788 fixes this. Installation for wolverine now uses vga=788
instead of vga=787 which was used previously, and as I recall the difference
between 787 and 788 is the bpp. Now we have a properly resolved bug. :-)
