[savage] unsuspending ends up with a (nearly) blank screen

[Christoph Bier]

Sleeping works but unsuspending doesn't. I get a console with "Linu" (sic!) in yellow color[1]. Nothing else, no reaction on pressing any key. I have to press the power button for about five seconds then the laptop is shut down.

chris@skull:~$ dpkg -l acpi* | grep ^ii
ii acpi 0.09-1 displays information on ACPI devices
ii acpi-support 0.75 a collection of useful events for acpi

Hardware:
IPC PowerNote M 8375 aka Mitac 8375

Graphics: S3 ProSavage8 KM266/KL266 (Xorg driver "savage")
Chipset: VIA Apollo Pro266 AGP (memtest86+ prints "VIA KN266")

Best,

FYI, there are more savage freezes in bug #38500 and bug #41340.

Thanks I didn't know! I was asked to file a bug and just didn't search for similar bugs. My mistake, sorry!

With Matthew's patch, that was already applied to /etc/acpi/resume.d/17-video-restore.sh on my laptop, I observed the following:

First attempt: Laptop goes to sleep but wakes up again immediately without pressing a key---but without any freezes.

Second attempt: After pressing the sleep button the logout-screen stays the same for minutes and syslog prints (watched remotely from my desktop): "localhost exiting on signal 15". After pressing sleep again it goes to sleep and stays there. Nothing new in syslog. But waking up fails now with the same result as described in my bug report. Remote session from my desktop is broken.

Later today I'll try without DRI.

Meanwhile I tried without DRI but I get the same result---a frozen nearly blank screen. Does a missing swap partition interfere with this (see https://launchpad.net/bugs/42561)?

I have also seen "exiting on signal 15" - I think that is just syslog itself shutting down, and nothing to worry about.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Thanks in advance.

[Christoph Bier (christoph-bier)]

Yes, but the behaviour has changed: The laptop is completely shut down when I try to suspend it.

Could you please include the information requested at [WWW] https://wiki.ubuntu.com/DebuggingACPI as separate attachments.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you?
If so, please post the latest outputs from the information requested on the DebuggingACPI page (don't forget the tarball at the end). Then we should be able to confirm the bug for you.
Thanks!

Hibernating/sleeping now works. But after suspending the network is gone. Here is the information you requested.

I just suspended again to provide /var/log/kern.log.0 but the laptop didn't wake up again. BTW: Rebooting still doesn't work (see also https://launchpad.net/bugs/67395).

[Tormod Volden (tormodvolden)]

Can you please try using the "vesa" driver instead of "savage" in /etc/X11/xorg.conf, so that we can see if this is a graphic driver issue?

[Connor Imes (ckimes)]

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as Triaged and let them handle it from here.
Assigning the Ubuntu Kernel ACPI team since this bug is filed against acpi-support and is a suspend/resume issue.
Please also follow Tormod's instructions so they can check if it is indeed a problem with the driver and not ACPI.
Thanks for taking the time to make Ubuntu better!

[Christoph Bier (christoph-bier)]

With the vesa driver the laptop doesn't suspend at all. I get a blank screen, keyboard is dead, network is down (remote login doesn't work anymore) and after about 30 sec the fan starts running---I guess because the CPU is running at highest frequency.

[Gabor Angler (angler-gabor)]

I have a similar problem. When I suspend from command line, after resuming from sleep state,
the screen is blank.
When I suspend from gnome, and resume from it, the screen flickers.

Thank you!

Does this still occur on Ubuntu 11.10 "Oneiric Ocelot"?
