2 Problems:
1) Close laptop (Power management system?) locks up, causing disabled
networking on reboot.
2) When reboot: Unable to reenable wifi networking.
I got no replies on the KUbuntu & Ubuntu mailing lists. I thought I'd
ask here on the KDE lists, because perhaps people who know about the KDE
interface to the network management system, or power management, or any
other KDE stuff, might have some insight.
Can you think of some likely problems? Heard of any problems like, or
related to this? Troubleshooting suggestions? Thanks :)
== Equipment & sw:
Compaq Evo N610c laptop from maybe 2003-7. 1GB, pcmcia 3com wifi using
atmel driver. Fresh KUbuntu 10.4 install, with apt upgrade for latest
packages.
{This had been, & continues to, run KU 9.04 fine, from another disk
partition}
== Problem occurance:
Worked fine for several hours. Then, while doing an ISO download,
via wifi (& no ethernet connection), I unplugged the power
& closed the cover. 5 minutes later I open the cover, & the
laptop is nonresponsive, though power LED is on, & screen is
backlighted, though black. Ctrl-alt-F1, c-a-delete, c-a-backspace does
nothing. touchpad fails to cause useful display.
(Point 1: Seems like a power management system, suspend, whatever is
from the standard settings, has a bug. The laptop shouldn't hang when
the cover is closed.)
Power off, then power on & boot up. Now networking is disabled, & I
can't find a way to enable it.
I mouse over icon of ethernet plug & socket: ¨Unmanaged¨
click on that icon: ¨Network Management disabled¨
Going to (IIRC) System settings > networking, the wifi settings are
still there, in the "wifi" section, but there is no place to turn on or
enable network management.
I insert the wifi card, and it doesn't show up under ifconfig, though it
does with iwconfig. Strange.

Thoughts? Suggestions? Thanks to you, & the great GNU(Linux) community
for the great KU10.4 sw & support. :)

{eth0 is the wifi card, which was inserted during the 10.4 install.
eth1 is the built in wired ethernet.}
{After insert the wifi card, it sees it (eth0) but fails to start the
networking properly}
