FC3test1: X / display hangs after overnight inactivity

[Banibrata Dutta]

Hi,

Anybody has noticed the problem of Xserver (or display driver) hanging
in FC3-test1 ? I've filed a bug in bugzilla # 132968 (
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=132968 ).

pciscan reports the display adaptor as:
pci bus 0x000 cardnum 0x02 function 0x00: vendor 0x8086 device 0x2572
 Intel Corp. 82865G Integrated Graphics Device

to summarize here's the problem:
 if i leave the Xserver running (WM being either GNOME / KDE based)
overnight, 9/10 time i'd find that the display as hung, i.e. a thin
raster band (in 16/256 colors) at the bottom of the screen. in this
state CTRL-BACKSPACE, ALT-CTRL-Fn or even ALT-CTRL-DEL doesn't work,
basically i cannot do anything using the console keyboard. if i telnet
into this system from some other system, i am allowed in, after which
if i try killing all X processes including gdm etc., the status
doesn't change, i.e. the raster band stays and keyboard remains
non-responsive. i've tried switching to runlevel 3, stopping X and
going back to runlevel 5, without any good. only option left at this
point is to reboot the system, or poweroff & poweron.

thanks & regards,
banibrata dutta.
