Description of problem:
Under RH 7.3, my Dell Inspiron 4100 could suspend and resume
while X was running with the lid closing and opening. Now, under 8, it hangs
the whole computer up. The keyboard is unresponsive.
Under 7.3, I had the stock XFree86, plus an early-access X driver
for the Radeon graphics from the driver author. That fixed a problem I had
with resume causing the screen to "melt down" and fixed a nonfunctioning
option to turn the laptop screen off when and external monitor is connected.
The author had developed this version of the driver for XF 4.2. It looks like
it is now incorporated in the RH 8 release. The author is firstname.lastname@example.org.
There do not appear to be any messages about this in the system log.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.configure BIOS to suspend when lid is shut
Actual Results: The fan goes on and it sounds like the system is going to
start up. The screen stays blank, and the keyboard is unresponsive (caps
lock, for example). Cannot reboot or halt computer. Cannot kill X session.
Have to power-cycle.
Expected Results: session resumes normally.
I also have this problem with RH8 on my laptop (Dell Latitude C800, ATI Mobility
M4), although I never installed RH7.3 on the computer. I cannot successfully
suspend to disk nor suspend to RAM.
Inspiron 4000; same. Works if I set apmd setuid and use "Suspend" from the gnome
panel battery applet, but not if I shut the lid.
Well, it did. I upgraded to kernel 2.4.18-17 today and suspend doesn't power off
the machine any more. This only happens when the ethernet card is in. Just filed
a new bug 76206.
I have similar behaviour on my Dell Latitude L400.
The strange thing is that it hangs on the *second* resume, the first
suspend/resume works fine. This is 100% repeatable. It happens whether or
not apmd is running, whether or not X is running, and none of the kernel
configuration options related to APM have any effect.
