2.6.1 on ATI Rage 128 M3: some thin vertical lines show up

2.6.1 on ATI Rage 128 M3: some thin vertical lines show up

[Harald Dunkel]

Hi folks,

Kernel: plain 2.6.1, booted with "vga=0x318"
Hardware: Dell C600 laptop
VGA: VGA compatible controller: ATI Technologies Inc Rage Mobility M3 AGP 2x (rev 02)
      (XFree86 says '"ATI Rage 128 Mobility M3 LF (AGP)" (ChipID = 0x4c46)')

If I run "make menuconfig" on the frame buffer console,
then some character cells (e.g. the top line to the right
of "Linux Kernel v2.6.1 Configuration") contain some thin
vertical lines in various colors instead of being plain blue.

Switching to another console and back to the menuconfig screen
does a clean-up, but new screen output will create the thin
vertical lines again.

It seems that only the character cells _without_ printed text
contain the thin lines. The same problem comes up with
running aptitude instead of menuconfig.

I can't remember having seen this problem with kernel 2.4.22,
but please don't count on this. Can anybody reproduce this
problem?


Regards

Harri

Just to clarify, are you talking about vesafb? I ask, because the
rage128 driver included in the kernel does not support flat panels.
That's the reason why I started a new driver for my Dell C600, which I
haven't ported to 2.6 yet (volunteers are welcome, see
http://www.saftware.de/r128fb/r128fb-20030819.tar.bz2 ;-).

Interesting... I'll look at this as soon as I'm done with my current
work (in a couple of weeks hopefully). I definitely plan to do some
major work on aty128fb so...

Yes, its vesafb. The Rage128 drivers have been compiled as a module,
but they are not loaded.
