[issue854] On ThinkPad T40: X display rather difficult to read if started the first time

[Christoph Biedl]

New submission from Christoph Biedl <grml.fksi at manchmal.in-ulm.de>:

Hi,

booting grml 2010.04 on an ThinkPad T40 notebook I noticed the display
of the X server is hard to read: Pale, poor contrast.  When trying to
debug it turns out this happens always after the first time X was
started.  Bringing it down and starting again yields the expected
behaviour.

For me, this is not critical at all as I use the graphical mode of
grml rather seldom.  It might be of interest for other, hence this
report.

Some facts:
* grml was booted both from the CD-ROM and via USB
* It doesn't matter whether X was started via the "x" in the menu at
  the end of the boot process; or using grml-x.
* The card is a:

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500] (prog-if 00 [VGA controller])
        Subsystem: IBM ThinkPad T42 2373-4WU
        Flags: bus master, stepping, fast Back2Back, 66MHz, medium devsel, latency 66, IRQ 11
        Memory at e0000000 (32-bit, prefetchable) [size=128M]
        I/O ports at 3000 [size=256]
        Memory at c0100000 (32-bit, non-prefetchable) [size=64K]
        [virtual] Expansion ROM at c0120000 [disabled] [size=128K]
        Capabilities: [58] AGP version 2.0
        Capabilities: [50] Power Management version 2
        Kernel driver in use: radeonfb

* You had suggested "i915.modeset=0" or "nomodeset".  Well, this isn't
  an Intel card, the latter did not change anything.

Regards,
    Christoph
