Lid close causes lockup, (black screen with white mouse cursor), only option is to power down.

System / Hardware info:
Slackware 14.1 huge Linux kernel 3.12.24
Dell x300 laptop with 1G RAM and 3G Swap
Pentium(R) M processor 1200MHz

I used Slackware 13.0 for 4 years previously (with 2.6x kernel), and lid close only turned off monitor, (I was perfectly happy with that). I installed Slackware 14.1 (restoring old /home/ to new system) and have suspend and hibernate working properly but lid close kills everything but power and a white mouse cursor on black screen. After installing Slackware 14.1, lid close becomes an unrecoverable situation, no response from keyboard or mouse and cannot ping the IP from other systems on the network - no response anywhere and nothing gets written to log files. Problem persists in KDE, XFCE4 as well as fluxbox and runlevel 3 (console mode). The stock kernel has the same problem but I thought a newer kernel might be the answer so I installed the 3.12.24 kernel using http://mirrors.slackware.com/slackwa...nfig-huge-3.12 but seeing same problem as before. I should also add that this system was unable to boot smp kernel. So I have this problem with huge kernel versions 3.10.17, and 3.12.24 so far.

From dmesg |grep Lid
[ 6.829143] input: Lid Switch as /devices/LNXSYSTM:00/device:00/PNP0C0D:00/input/input6
[ 6.829956] ACPI: Lid Switch [LID0]

You might try
(a) telling us a bit about your system, e.g. the output of lspci for starters.
This sounds a bit like a "common" video mode problem.
(b) compiling and running a 3.15.x or 3.16.x kernel.

Cheers.

You might also run the queries at the top of this page and report their output:

http://slackware.osuosl.org/slackwar...ADME.SLACKWARE

That will provide information about the power-management capabilities of that machine.

SOLVED:
I found that huge-3.4.66 works ok on this hardware, (lid close successfully activates suspend, lid open successfully recovers).
Kernels huge-3.10.17, huge-3.12.24 and huge-3.16.4 all gave me same problem.

Glad to see you found a working kernel. If you are really energetic, you could file a bug report with the kernel guys.
