Laptops :: DSL freezes on IBM ThinkPad 390e

I've solved the screensaver problem but my 390e still freezes when I close the screen lid or when I press ctrl+alt+del. And it happens every time. The same thing happens in DSL-N. Very frustrating, cos I've tried everything, disabled all APM features in BIOS, dpms and screensaver are turned off with xset, but still it doesnt' help.

In this state DSL is unusable because I can't leave the laptop on overnight without keeping the screen up (the LCD backlight will wear off prematurely).

Well, you can disable ctrl+alt+del if you want.. but I'm guessing the all of these things are under one root problem.

I suppose you already tried noapm noacpi apm=off acpi=off nolapic noapic ... perhaps it's some hardware driver that's doing it? You could try disabling some and see if that helps (maybe paste out your stats.txt). Does it also happen with failsafe? What if you don't go into X but i.e. boot into runlevel 2?

THanks for your tips, ^thehatsrule^! I'll try nolapic and failsafe, didn't know about them. I think it would be great to solve this, because it seems to be a general problem on 390E model, because I've been getting emails with questions about it from other users as well. And it impedes use of otherwise a pefect distro for this comp. I'll let you know very soon if the new options were to any avail.

by the way, what's the difference between apm=off and noapm etc? and what's nolapic? and difference between apic and acpi?

well not sure myself... other distros seem to use both. I seem to remember some reporting one working over the other if used separately.

the l is for local apic; acpi is for power stuff; apic is for interrupts something... could google for more info, but I'm just pulling stuff out of nowhere here.
