Bug Description
Binary package hint: acpi-support
I have an Everex StepNote 2053 T laptop (see below **) that doesn't resume after a suspend in Ubuntu 8.10 Intrepid; worked fine in Hardy.
More details: I recently updated from Hardy to Intrepid, using the Update functionality of the GUI-based package manager. I've since updated to the latest package releases, and am running the 2.6.27-9-generic kernel at the moment (will attach more detailed system info). I have the SDHCI and SDHCI-PCI modules blacklisted (see Bug #187671), but other than that it's a fairly standard Intrepid install. I'm apparently running version 0.114 of the acpi-support package.
When I boot into this kernel, the earlier 2.6.27-7-generic kernel, or a 2.6.27.7 kernel I compiled form kernel.org source, and I suspend the laptop from the System / Shut Down menu item in Gnome, the laptop fails to resume. Booting into an old 2.6.26 kernel I compiled myself from kernel.org source, suspend/resume works. It also used to work fine in Hardy using kernels supplied by Ubuntu (which were conveniently erased when I upgraded to Intrepid) when I was still running Hardy.
What I'm seeing with the current kernels, after I suspend and then hit the space bar to try to resume, is a blinking cursor in the upper-left of the otherwise black laptop screen. In fact, before I added this line to my startup sequence
echo 3 > /proc/sys/
I couldn't even see the cursor -- the screen was just black (I added this line to startup because a friend with a different laptop was seeing a black screen and this fixed his problem, but it didn't fix my problem, just made the cursor visible). The fan and drives start up and make noise, but the laptop isn't usable.
I've tried control-alt-f1 (and other f-keys) and control-
I will attach lspci output and some other system output, and do some more debugging (I found debugging guides https:/
** Here is a list of laptops which are apparently all clones of this one:
* Averatec 2460
* Everex Stepnote SA2050
* Everex Stepnote SA2050T
* Everex StepNote SA2052T
* Everex StepNote SA2053T
* Philips Freevents x52
* Philips Freevents x53
* Philips Freevents x54
* Philips Freevents x55
* Philips Freevents x56
* Twinhead H12Y
OK, this is interesting. I was playing around with some of the debugging suggestions on this page http:// ubuntuforums. org/showthread. php?p=3066404
I found that after a reboot (to make sure I had reset the system to its normal state), If I went to a terminal window and typed run/ifstate file didn't exist, and a couple "Function not supported lines, and on resume, module acpi_sbs not found), but everything resumed without any problems.
sudo /etc/acpi/sleep.sh force
everything worked fine. There were a few warnings on the screen (e.g. that /etc/network/
So it appears that the problem is with the Gnome menu item suspend, rather than with the sleep.sh script.
If I can figure out how, I will change the package this is reported against, but if I can't figure it out, can someone do that? I don't think the problem is with ACPI if sleep.sh works, is it? And it doesn't look like any of the debugging things will be all that useful, because all of them are debugging problems with sleep.sh and not with the Suspend menu item in Gnome.
Anyway, I'm happy to run other tests, just add a comment and I'll see what I can do.
