[PATCH] Sony C1V Clock Generator miss detect work around
Package: xserver-xfree86
Version: 4.0.1-1
xserver-xfree86 does not work on Sony C1V series.
(English version is C1JE/Japanese version is C1VJ)
This machine's specs are like this:
CPU: Crusoe (TM5600 600Mhz)
Graphic Chip: ATI Rage Mobility (with Power Management)
Video RAM: 8 MB
LCD: 1024x480
This machine's graphic subsystem uses Internal Clock Generator, but
current XFree86 4 (current CVS) can not detect this correctly on the
machine :-< like this:
(WW) ATI(0): Unknown programmable clock generator type (0xFFFFFFFF) detected.
(--) ATI(0): Pixel clocks available:
(--) ATI(0): pixel clocks: 0.000 0.000 0.000 0.000
So XFree86 runs with incorrect setting of clock generator and can not
display X on LCD (white out....).
This is a work around patch force to set `To use Internal Clock
Generator'. When `ClockChip "Internal"' will set in Device section of
XF86Config, ati_drv force to use Internal Clock Generator.
I'll happy if include this next release of xfree86-4.0.1.deb :-)
Of cause I understand this is the upstream problem and the patch is
a only `WORK AROUND'. I already posted this report to
devel@xfree86.org and I'll debug to fix this problem basically as
soon as possible.
P.S
This machine is tuned only for WindowsMe. To use Linux on this
machine is a little difficult...
For example power management does not work correctly, can not resume.
and Kernel 2.4.0-preX hangs up on this machine :-< etc etc etc.....
