The diff between 2.6.18 and current git doesn't show any critical changes for gbefb.c ... I am not sure about that. The colors with 2.6.18 are better than with current but still not quite what I would expect. Perhaps there are just not enough colors or perhaps the 2.6.18 default colormap is closer to what X would want to set. Also when I kill the X server with Ctrl+Alt+- the colors seem momentarily corrected before the X picture is cleared ;-) Thanks MS -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Perhaps there are just not enough colors or perhaps the 2.6.18 default colormap is closer to what X would want to set. 2.6.18 is probably not much better, I was just lucky, when I tested it. I've fixed the 8bit color modes and 16/32bit modes are working with framebuffer console. What's still broken is X with 16/32bit mode. This is probably because of the wrong endianess of the framebuffer when mapped to user space by the X server. But that's something the kernel can help much, because that's how the hardware works and therefore fixing this in the X server makes much more sense. Thomas. -- Crap can work.

Michal, Can you please test the kernel from http://merkel.debian.org/~tbm/tmp/ip32/linux-image-2.6.26-rc8-r5k-ip32_2.6.26~rc8-1~experimental.1_mips.deb This has the fix from Thomas. -- Martin Michlmayr http://www.cyrius.com/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Yes, this fixes the colors. I get good colors in 8bpp and 32bpp. However, I have to change the framebuffer bpp on all consoles to get X use a different depth. Also when I change the mode I (not only the bpp) using fbset I can no longer start X. I get (EE) FBDEV(0): FBIOPUT_VSCREENINFO succeeded but modified mode Thanks Michal -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
