Hello,
No one's been able to help with these problems on the forums or in
IRC, and Google yields no useful info after... probably 20-30 hours
of searching combined. Any help would be greatly appreciated:
Setup:
Toshiba Portège m200 laptop (with a GeForce FX Go 5200 - appropriate
kernel modules installed)
using KDE 3.5.0 and with latest ver
Problems:
1) The boot hangs at "uncompressing linux" for the good part of a
minute. (If I have the splash screen enabled, it will never get past
the first step and return to the text screen after the hang.) When I
removed the 'quiet' boot option, I see:
...
...some lines about ACPI
ICH4: not 100% native mode, will probe irqs later
... some line I didn't have time to read
[4294676.411000] ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
[hang for 1 minute or so]
2) All my login prompts from ctrl-alt-f1 through f6 are all black. I
think this started after I installed NVidia. Is there a way around
this? (Oddly I think they're still functioning -- you just can't see
them.)
3) [most severe and infuriating problem:] My laptop's screen
periodically goes blank. This happens from time to time when it's
plugged in (I haven't measured it... sometimes it doesn't happen at
all.) However, I know this happens every 2 minutes when the computer
is on battery power. When the laptop's screen goes black, there are
only two ways I can get out of it: If I hit power, the X server
crashes; if I hit ctrl-alt-f6, and ctrl-alt-f7, then the screen
slowly returns to normal, but then Firefox will crash (Firefox crash
error log: http://www.ubuntuforums.org/showthread.php?t=127198). This
prevents me from using my computer in class. :-(
This is extremely odd for 3 reasons:
- I've tried to turn off sleep *everywhere* I can find it. Is there
some place I've missed? Is there an ACPI config file to check? Could
enabling "laptop mode" support cause this behavior?
- I've checked the BIOS settings: The computer is set to power off
the monitor on battery mode every 3 minutes, not 2 minutes... I think
I've disabled BIOS powersaving behavior but the interface is poor and
I'm not 100% sure.
- "cd /etc/acpi; sudo ./sleep.sh" will sleep the computer perfectly
well and wake it up fine with the power button -- no problems whatsoever
I've also tried acpi=off and other similar boot parameters; they
haven't fixed the problem (but I'm not 100% I had the right one).
(Is there some way to debug ACPI? Like append debug output to ACPI
scripts?)
4) Hibernate doesn't work: the system will try to unhibernate, but
when it tries to "restore to highmem", the screen gets filled with
funky graphical artifacts and I have to do a hard reboot.
5) Shutdown doesn't work: the screen will go off and the HD will stop
being read, but the computer still remains active. I have to do a
hard shutdown every time.
6) [this isn't a hardware-related problem:] KDE's login manager
doesn't show the "Greeting" and Logo as selected in KControl. Is this
normal?
7) [this isn't a hardware-related problem:] The battery kicker applet
does not show up with kompmgr is enabled; one has to disable it and
reenable it in KControl to get it to work. Also it doesn't update
properly: goes from 31% to empty instantly.
8) Might anyone know of a utility that lets one browse for wireless
networks, much like Windows XP?
Any help would be greatly appreciated.
Thanks,
Mats Ahlgren
P.S.: I'd recommending changing the default boot behavior of Ubuntu
network detection on laptops. I had to do the following tip posted on
the net to fix a 1-minute hang every time my laptop would boot up:
sudo update-rc.d -f networking remove
sudo update-rc.d networking defalts 99
