no suspend in 16.04 PPC

[Fritz Hudnut]

Gents:

I just did an install a few days ago using the Alpha1 live DVD on my Powermac 3,1 PPC . . . and overall it's a very nice system. But, one dealbreaker for me is lack of "suspend" from either desktop or log in manager . . . . The screen does indeed go black, but the computer keeps spinning along as nothing has happened . . . and clicking mouse and or keyboard doesn't revive the display. The computer has to be shut down using the power button.

I ran a large "dist-upgrade" the next day after the install and the problem persists; so I don't know if that is now "Alpha2"??? Problem replicated after the update . . . . Doesn't look like anyone else has had this issue, but is a problem that I've had with many iterations of ubuntu 12.04, 14.04, and now 16.04 . . . . I have 2 GB RAM and swap is 2.7 GB . . . .

Same issue on a Powerbook 5,6 (installed it from yesterdays 2016-02-13 daily live).

The following page documents several known issue with suspend on the PowerPC.

At the very bottom of that page it suggests installing `pbbuttonsd`. Can you install that and let me know if it helps?

@Martin:

Thanks for the post and suggestion; I'll post back when I've had a chance to do that and test it out . . . couple days probably . . . .

@Martin:

The link you provided seemed to be about the cursor disappearing when using compiz . . . nothing mentioned about "suspend" or pbbuttonsd . . . .

But, I booted into 16.04, ran apt update/upgrade, I see there is a large upgrade available . . . nothing on pbbuttonsd, so I went to Synaptic and checked it and it shows that version 0.8.1a-2, the latest version, is installed . . . . That mentions "apple hotkeys" for eject and other stuff, but nothing about "suspend." Since I just checked this the other day and suspend didn't work I can assume that nothing has changed via pbbuttonsd for this issue . . . .

Same problem on a HP Pavilion g6. When I boot from ISO, it works as expected, but after install and upgrade, I get a black screen and a nonresponding spinning system. I did not try suspend before upgrade.

I tried sudo apt install pbbuttonsd, but got the massage "no available version". What is the proper way to do this?

This wiki page is referenced in the Ubuntu MATE release notes, and has been for sometime :-)

  * https://wiki.ubuntu.com/PowerPCKnownIssues

In that page is the following text:

If you need suspend then you'll have to use the fbdev driver, but you'll want to increase the default colour depth via a yaboot parameter (for example, video=radeonfb:1024x768-32) or an xorg.conf:

Section "Screen"
  Identifier "Screen0"
  DefaultDepth 24
EndSection

@Martin:

I've been playing with PPC linux for perhaps 5 years, and during that time I have tried all of the "known issues" solutions to get "suspend," and for me, none of them are "valid" . . . . Over in Linux Mint on my MBPro I have working "suspend."

The point being that "suspend" is such a ***basic*** function that there really is no excuse why it isn't working--out of the box. I posted this bug here because I was under the impression that 16.04 PPC was shooting for a high quality system, one that provides ***full function**** and not kicking the can down the road . . . as has been done before and seemingly continues to be.

So far I haven't needed an xorg.conf file or Yaboot params to get the basic GUI function; perhaps if there is a rainy day in LA I'll test it out--but I have very low expectations that either of those suggestions will work--been there, done that . . . increased the size of the swap, increased the RAM . . . until it gets written into the kernel I don't believe that anything will actually work to provide the very basic function . . . I'm stepping away from the computer to have a meal; I don't need to keep the computer spinning, but I don't want to go through the boot sequence every time I need a break . . . that description apparently doesn't enter anyone else's mind as ***necessary***?????

@Martin:

Does it apply to a HP as well?

Found out it is somewhere after kernel 4.4.0-7 the problem occurs. When I boot 4.4.0-7, standby works fine. I tried 4.4.0-14-15-17, they all lock the system with a black screen and spinning system, when going into standby.

Ti seems to be the same thing, look there
