I have a Raptor card (Texas Instruments TVP4020 [Permedia 2]) in my Netra t1125, which uses the glint xorg driver. This is detected and starts up fine, however once I am in Gnome I get a yellow trail which follows the mouse around, some of the icons have a yellow highlight and some text a yellowish tinge. Unfortunately I can't take a screenshot as the screenshot application crashes when I try to use it.

What I experience is very similar to this xorg bug however that's the ATI driver.

Does anyone have this card working correctly? Or should I be filing a bug with xorg?

This is a "me too" .... not suprising since I have the same card,
bought from the same E-bay seller a few days after yours.

On my Ultra 60 running 2.4.29 with xorg-x11-6.8.2-r1 I get the
same yellow highlights on icons, menu entries and some text.
Running the mouse over an icon is sometimes enough to remove the
highlight. Xterm is not affected so I guess I can live with it.

No yellow mouse trails but that will be because I run IceWM.
I tried all options on the "glint" manpage without success,
though switching to 8-bit depth removes the fault!

Yesterday I worked out how to fix it... and am now running happily without yellow trails :-)

The trick is to get glint to use the frame buffer (the relevant section from xorg.conf):

Code:

Section "Device"
        Identifier  "Card0"
        Driver      "glint"
        VendorName  "Texas Instruments"
        BoardName   "TVP4020 [Permedia 2]"
        BusID       "PCI:0@1:2:0"
        Chipset     "ti_pm2"
        Option      "UseFBDev"  "True"
EndSection

Thanks for the tip. For the record, what kernel and xorg versions
do you have success with?

I tried "UseFBDev" on my not-so-current machine and X starts with
no errors or warnings but the display switches to the initial
black-on-white Prom screen and then freezes. Perhaps permissions
on /dev/fb0 are not right but I ran out of time for this project.

I'm not at the machine now, but I'm pretty sure these are the versions:

xorg-x11 - 6.8.2-r4
gentoo-sources - 2.6.15-r5

Did you compile support for the permedia 2 frame buffer into the kernel? If you're getting the black on white then it sounds like you mightn't have done that... Let me know if you want my kernel .config.

My 2.4 kernel was built with CONFIG_FB_PM2, CONFIG_FB_PM2_PCI etc
and it seems happy because /var/log/messages has
"fb0: Permedia2 PCI board (Permedia2), using 8192K of video memory".

Also, I get a nice console if I boot with video=pm2fb:mode:1024x768-75

Thanks for the .config offer but I plan to leave this machine alone
for a while before making the jump to 2.6.
