Hullo all.
I had a very similar problem with the upgrade to 8.10 on my Fujitsu
P5020 (Intel 82852/855GM Integrated Graphics Device, of course).
Completely at random X would crash, forcing me to log in again. The rest
of the system was working, on the other hand. The "both planes enabled"
message I saw in Xorg.0.log is what brought me on this forum, in fact :)
After a tad of digging (forget now the source - but kudos to whoever had
this idea, my lappy runs very happily now) I found a workaround, and
would be glad to share with the community. In short, take the xrandr
output, and disable in xorg.conf the device you won't use. Not the most
elegant solution (the bug is still there, but I personally can live with
that).
E.g., on my lappy xrandr listed three devices: VGA, LVDS and TMDS. Based
on this, my xorg.conf contains the following:
Section "Device"
Identifier "Configured Video Device"
BusID "PCI:0:2:0"
Option "monitor-TMDS" "dvi"
Option "monitor-VGA" "vga"
Option "monitor-LVDS" "lvds"
EndSection
Section "Monitor"
Identifier "dvi"
Option "Ignore" "true"
EndSection
Section "Monitor"
Identifier "vga"
Option "Ignore" "true"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection
Now xrandr outputs only LVDS; and the only odd thing in Xorg.0.log is
(II) intel(0): I2C device "LVDSDDC_C:ddc2" registered at address 0xA0.
(II) intel(0): I2C device "LVDSDDC_C:ddc2" removed.
(TONS of these two lines). However, I don't experience anymore the
random X crashes. Go Ibex.
Hope the above helps.
Now if someone can show me how to enable the built in SD card reader
(the infamous O2Micro one) ...
Cheers.
Cosmin
